Inella harryleei – Leal 2021: 6 , fig. 38. Type material Holotype USA • sh; Florida , off Dry Tortugas ; depth 90 m ; FLMNH 419182 . Paratypes See Rolán & Fernández-Garcés (2008) . Material examined GUADELOUPE ( Karubenthos 2 expedition ) • 2 sh; stn DW4592; MNHN . Emended description Shell sinistral, conical-fusiform, up to 15.9 mm long, 2.4 mm wide, length/width ratio 6.6, apical angle of early whorls 11°. Protoconch paucispiral, three whorls, 0.96 mm long, 0.57 mm wide; first whorl smooth, inflated, only slightly narrower than subsequent whorls, which have two thin, nearly smooth spiral cords, situated at 33% and 76% of last whorl height; transition to teleoconch nearly indistinct. Teleoconch with up to 20 whorls; two spiral cords (adapical and abapical) in beginning of teleoconch, continuous to those of protoconch, but abapical one considerably more developed until body whorl; median spiral cord emerges very narrowly at end of second whorl, slowly developing but never reaching same size as other cords; suture shallow, with a smooth to slightly wavy sutural cord; 16–17 opisthocline axial ribs on 12 th teleoconch whorl; medium to large-sized (on abapical cord), rounded to slightly elliptical nodules; nodulous, moderately thin subperipheral cord, with a slightly nodulous adapical basal cord right below it and a thin, nearly smooth abapical basal cord situated apart; no evident supranumerical cord; nearly rounded aperture, 1.1 mm long, 0.84 mm wide, length/width ratio 1.3; anterior canal very long, partially open, directed downward, 1.0 mm long, 0.45 mm wide, length/width ratio 2.3. Shell mainly white, stained by few and discrete light brown (or cream) axial patches, usually comprising width of one or two axial ribs. Fig. 1. “ Inella ” harryleei Rolán & Fernández-Garcés, 2008 . A–E . MNHN, stn DW4592, 15.9 mm, 10.6 mm. Scale bars: A–B, D–E = 1 mm; C = 500 µm. Remarks The only known protoconch of “ I .” harryleei from Guadeloupe ( Fig. 1C ) has a first whorl apparently more inflated than those illustrated in the original description, from Florida and Louisiana ( USA ), although all other shell features are very similar. Based on the nearest record from the Florida Keys ( Rolán & Fernández-Garcés 2008 ), the present record extends the known range of “ I .” harryleei by ~ 2180 km into the Caribbean. However, Rolán & Fernández-Garcés (2008) indicated a shell fragment from the ‘West Indies’ as possibly belonging to this species. Lamy & Pointier (2018: 284 , pl. 91 fig. 7a–b) identified a shell from Guadeloupe as Inella aff. harryleei , following the morph from Florida illustrated by Rolán & Fernández-Garcés (2008) under this name. In fact, the teleoconch of this shell from Guadeloupe differs from that of “ I .” harryleei (see Rolán & Fernández-Garcés 2008 for further details). Moreover, this shell has an abapical spiral cord that is even more prominent than that of “ I .” aff. harryleei from Florida. Unfortunately, the broken apex of the shell from Guadeloupe precluded further comparisons. Lamy & Pointier (2018) indicated a depth range of 55–360 m for this morph; considering that “ I .” aff. harryleei from Florida is only known from 55 m ( Rolán & Fernández-Garcés 2008 ), only the depth of 360 m is confidently assigned to this peculiar shell from Guadeloupe . Geographic distribution USA : Florida ( Rolán & Fernández-Garcés 2008 ; Fernandes & Pimenta 2019b ), Louisiana ( Rolán & Fernández-Garcés 2008 ; Garcia & Lee 2020 ); Guadeloupe (this study). Bathymetric distribution Empty shells previously known from 46–500 m ( Rolán & Fernández-Garcés 2008 ), live specimens only known from 63 m ( Fernandes & Pimenta 2019b ). This study: 201–214 m (empty shells).
