Type material. Syntypes, 2 females, 5 mm, ZMB 20319. Type locality. North Atlantic ( 17°28'N , 29°42'W ), 3000 m. Depth range. 0-4000 m ( Schellenberg 1926a , Hendrycks and Conlan 2003 ). Distribution. Atlantic Ocean : approximately 650 kms west-north-west of the Cape Verde Islands ( Schellenberg 1926a ); west of South Africa ( Schellenberg 1926b ). Indian Ocean : approximately 1100 kms west-north-west of Cocos (Keeling) Islands ( Birstein and Vinogradov 1964 ). Pacific Ocean : Kurile-Kamchatka region ( Birstein and Vinogradov 1970 ); United States, west of California ( Hendrycks and Conlan 2003 ). Southern Ocean : Antarctica, approximately 600 kms north of the Oates Coast ( Birstein and Vinogradov 1962 ). Figure 35. Distribution of Scopelocheiropsis abyssalis Schellenberg, 1926. Star indicates type locality. Figure 36. Scopelocheiropsis abyssalis Schellenberg, 1926. Syntype female, 5 mm, ZMB 20319, mid Atlantic Ocean. Whole G1, G2, P4, P5 after Schellenberg 1926. Scales for P3, P7 represent 0.5 mm, remainder represent 0.1 mm. Discussion. Scopelocheiropsis abyssalis was originally described and illustrated as lacking a mandibular molar. Hendrycks and Conlan (2003) described new material and indicated the presence of a small molar. We have re-examined one of the syntypes of this species and can confirm the presence of a molar on the type material (see Figure 36 ).
