6o GUDE . DESCRIPTION OF A NEW SPECIES OF CHI.OKITIS. 



Shell globose, moderately umbilicated, blackish chestnut, of a deeper 

 shade towards the mouth. Spire conical, apex sunk, suture impressed. 

 Whorls 4}4, globose, the first 2 J/2 increasing slowly, the last 2 widening 

 rather suddenly, the last dilated above and a little constricted belo.v, 

 behind the peristome, and flattened laterally for some distance further 

 back ; finely striated, the earlier 3}^ whorls with oblique rows of hair- 

 scars ; a shallow furrow encircles the body-whorl at the periphery. 

 Last whorl decending shortly but rather deeply in front, angular round 

 the funnel-shaped, deep umbilicus. Aperture semi-ovate ; peristome 

 thickened and shortly reflected, dark brown, the margins slightly con- 

 vergent, columellar margin triangularly dilated and reflected over the 

 umbilicus. 



Diam. maj. 34, minor 28"5 : alt. 30 : apert. 14 5 millim. 

 Hah. — Collingwood Bay, British New Guinea. Tiji/r in my c(jllection. 



Compaired with Ohloritis reh.^ei, Mart., its nearest ally, the new 

 species is darker in colour, smaller, the spire is more compressed and 

 elevated, the last whorl decends more and is less globose, the peristome 

 is much less reflected, dark brown instead of bluish, and the outer 

 margin is not sinuous, while the umbilicus is narrower. The sudden 

 deflection of the last whorl is not well shown in figure 4.

Recently"' I published a few brief diagnoses of some new shells from 

 this district, collected by Mr. J. Waterstradt, and I am now enabled 

 to give a fuller account of the collection, \vith illustrations. For the 

 present, the Helicoids have been omitted, in the hope that some 

 person, more conversant with the group than I am, may deal with 

 them.
