Monodilepas otagoensis
Monodilepas otagoensis Finlay, 1930.[1]
Monodilepas otagoensis was originally discovered and described by Harold John Finlay in 1930.[1] Finlay's original text (the type description) reads as follows:
| « |
Monodilepas otagoensis n. sp. (Fig 6). Very close to monilifera (Hutton), the genotype, but differing in its coarser radials (less affected by the concentric ridges, so that the pits are less prominently hexagonal), more depressed shell, which is less pointed anteriorly especially in the adult, and a notably smaller foramen. The internal callus, as in monilifera, is subtriangular, the hinder margin being straight. Length, 10 mm.; breadth, 7.8 mm.; height, 2.5 mm. Locality—50 fathoms, 10 miles E.-N.-E. of Otago Heads, type and three others. Type in Finlay collection. Juveniles are difficult to separate from monilifera, but adults are easy. I have not seen this species from any other locality. Typical monilifera is in my collection from 15 fathoms, Stewart Island (topotypes); 50 fathoms, Snares Island; 50 fathoms, Oamaru; and Lyall Bay. |
