TYPE MATERIAL. — Holotype ( IMT 85-21 ; not examined; figured by Higo et al . [2001: 66 , G2401]). TYPE LOCALITY. — Mactan, Cebu , Philippines . MATERIAL EXAMINED. — BENTHAUS, stn DW 1948, Banc Lotus, 23°48.7’S , 147°53.5’W , 120-280 m , 1 lv ( Fig. 5A, B ). DISTRIBUTION. — Pacific Ocean, from off Danjo Islands, Western Kiūshū ( Higo et al . 1999: 217 ; Tsuchiya 2000 ), to the Philippines and the New Caledonia area, alive in 245-400 m ( Oliverio 2008b ). Austral Islands, alive in 120- 280 m . REMARKS The protoconch, partly eroded, of the single specimen, is concordant in the general aspect with the known protoconchs of this species, indicating a planktotrophic larval development. C. mitraeforma is very similar to C. solutistoma Kuroda & Shikama, 1966 , differenciation relying on its higher ratio total height/apertural height (h/a).
