This has somewhat the appearance of a minute slender 

 form of 0. iulennedium, but it is quite a distinct species. 



Species 36. (Fig. u, b, Mus. Taylor.) 



Ovulum dentatum. Ov. testa lanceolaio-pyr'^formi, 

 flcivescente-ulbn, spadiceo obscure inquinatd, dorso un- 

 diqiie transversim iiiciso-striato, extremitatibns canal'i- 

 ciilato-prodiictis, labro varicoso-incrassato, dantato- 

 serratu, columelld siipenie deulato-cuUosd, Inferne

 Islands, Japan (at the depth of forty-eight fathoms) ;

A very interesting species, of which the characters above 

 detailed are very neatly and prominently developed. The 

 two habitats here quoted show a tolerably wide distri- 

 bution. 



Species 37. (Fig. a, b, Mus. Cuming.) 



Ovulum hordaceum. Ov. testa elonr/ato-oljtouyd, pur- 

 piirascente-ftavd, vivide anrantio marginatd, dorso sii-

 lahro planato, profuse dentato-serrato, pone Jiiiibriato, 

 extremitatibus conspiciii canalicidato-prodiictis, colii- 

 meild superne. dentalu-serratd, liaiid plicatd. 



The bakley Ovulum. Shell elongately oblong, pur- 

 plish-yellow, edged with bright orange, back gib- 

 bously angled at tiie upper part, transversely incisely

JIab. ? 



Another species typically allied to the preceding, in 

 which the details Ijoth of colour and sculpture are conspi- 

 cuous. 



Species 38. (Fig. «, b, Mus. Cunn'ng.) 



Ovulum Traillii. Ov. testa lunceolalo-ovatd, albidd, 

 rosaceo-fnscescente tinctd, dorso medio gibboso, Icevi-

Traill's Ovulum. Shell lanceolately ovate, whitish, 

 tinged with pinkish-brown, back gibbous iu the

 ture narrow, columella callously smooth.

Ilab. Malacca; Dr. Traill. 



A very characteristic species, although the details of 

 sculpture are somewhat obscurely developed. In form it 

 is peculiarly slender and delicate. 



Species 39. (Fig. a, b, Mus. Cuming.) 



Ovulum FOEMOSUM. Ov. testa lauceolato-ovatd, purpu- 

 rascent.e-aurantid, dorso uiidique transversim inciso-

 produclis, labro varicoso, conspicue dentato-serrato.
