Mario Alcocki, sp. n. 



Testa ovato-fusiformis, ventricosa, tenuis, alba, periostraco tenui 

 olivaceo griseo induta, spiraliter tenuiter lirata, lineis incre- 

 menti tenuibus arcuatis striata ; anfractus 9, sensim accresceutes, 

 convexi, sutura profunda canaliculata sejuncti, ultiraus ant ice 

 contractus, ad aperturam ascendens ; apertura obliqua, all)a, sub- 

 auriformis ; labrura vix incrassatum, leviter expansum ; colu- 

 mella in medio arcuata, callo tenui lato labro juncta; canalis 

 anterior obliquus, recurvus. 



Longit. 99 mm., diam. max. 61 ; apertura cum canali 61 longa, 

 27 lata. 



Operculum corneum, dilute fuscescens, elongatum, conccntrice 

 striatum, prope nucleum paucispirale ; nucleus baud centralis. 

 Longit. 37 mm., diam. 18. 



Hab, Station 280, off Coromandel coast, 446 fath. 



In form rather like the M. rugosa, Linn., of the JNIediter- 

 ranean and N. Atlantic, but with a rather longer spire, a 

 broader aperture, finer liration,and a more deeply channelled 

 suture. It is also imperforate, the columellar callus being 

 appressed to the shell throughout its length, and not free 

 and prominent as in the species referred to.

A single specimen, length 42'5 mm., diam. 28, differs 

 from the ' Challenger' Atlantic form in size and in possessing 

 an unclosed umbilical opening. The latter, however*, might 

 possibly be concealed if the columellar callus were not 

 broken at tliat part or had the specimen lived a little longer 

 and so completed the reflection of the callosity. The spiral 

 lirse appear to be rather more remote from one another, but 

 this results from the larger size of the specimen. Tiie 

 remarkable lines of growth, causing the lirre to be crenulatcd, 

 are of the same character in both specimens, and the oper- 

 culum is horny and spiral, as described and figured by 

 Verrill * of his genus Benihodoliuin; which is evidently
