Species 33. (Miis. Sowerby.) 



NucULA NASA. Xur. lestd parvd, nitenti, olivaced, 

 oblique trigond, elevatd, prnpe umbones tumidd, medio 

 subcomplanatd, intHs subaured ; latere postico 

 hrcrissitno, perpendiculai-i, apice ohtnso ; latere 

 autico obliquo, obtuse nnrjulato, convexo. 



The uwakf Nucula. Shell small, shining, olivaceous, 

 obliquely trigonal, elevated, tumid near the um- 

 boes, rather flattened in the middle, slightly 

 golden tinted within; posterior side very short, 

 perpendicular, apex obtuse ; anterior side oblique, 

 obtusely angular, convex. 



Hinds. Voyage of the Sulphur. 



Nucula Delphinodonta, var. Hanley. 



The little shell figured in Thesaurus certainly ap- 

 pears different from .V. Delphinodonta, and much more 

 like the specimens figured in this plate, although I 

 cannot be quite certain as to the identity. 



Species 34. (Mus. Brit.) 



Nucula Malabaiiica. Nuc. testa parvd, triyond, sub- 

 (squilaierali, pallidd, temii, concentrice tenuiter 

 liratd, elevatd; latere postico breviusado, infrd 

 rotvndato-aubangulato ; apice elevato, aaiminato, 

 margine ventrali subpvducto, infrd, acuminata, 

 latevibns declivibus ; margine cardintdi tato, deniibvs 

 panels. 



The Malahak Nicula. Shell sraaU, trigonal, subequi- 

 lateral, pale, thin, concentrically finely lirated, 

 elevated ; posterior side rather the shorter, roundly 

 angular below ; apex elevated, acuminated, ventral 

 margin slightly produced, acuminated below, sides 

 sloped ; hinge margin broad, teeth few. 



Hanley. Proc. Zooh Soc, 1860. 



Hah. Cochin, Malabar. 



A very small elevated shell, more nearly equilateral 

 than most of the species.

Species. 35. (Mus. Hanley.) 



Nucula ^Egeensis. Nuc. testd ovatd, subcompressd, hum, 

 tenui, pallidd, politd ; latere postico suhproducto, 

 suhrotundo, lumdd brevi, convexo, distincto ; apice 

 prominenti, margine ventrali eequaliter convexo,; 

 latere autico producto, acuminata, margine dorsali 

 recto. 

 The ^Egean Nucula. Shell ovate, subcompressed, 

 smooth, thin, pale, polished ; posterior side a little 

 produced, a little rounded, lunule short, convex, 

 distinct ; apex prominent, ventral margin equally 

 convex; anterior side produced, acuminated, 

 dorsal margin straight.

 Hab. Maori and Crete, yEgean. In deep sea. 



The reverse of the preceding in its lateral and per- 

 pendicular proportions. 



Species 3G. (Mus. Brit.) 



Nucula Layardi. Nuc. teM ovatd, subcompressd^ 

 vtriiique acuminatd, tenui, epidermide politissiiiid 

 suhviridi indutd ; latere postico jyroducto, acu- 

 minata, lunulA brevi, circumscriptd, apice acuminata, 

 margine ventrali mqualiter convexd ; latere antico 

 elongato, acuminata, ared dorsali cotmexo, ad un- 

 guium depresso. 



Layard's Nucula. Shell ovate, subcompressed, acu- 

 minated at both ends, thin, covered with a very 

 polished greenish epidermis; posterior side pro- 

 duced, acuminated, lunule short, circumscribed ; 

 apex acuminated, ventral margin equally convex ; 

 anterior side elongated, acuminated, dorsal area 

 convex, depressed at the angle. 



A. Adams. Proc. Zool. Soc, 1856, p. 51. 



Hab. Ceylon. 



It is scarcely with Nucula convexa that this shell 



need be compared, as is done by its describer. It is 



much more closely allied to the larger species named 



Nucula Cumiugii.
