with Tate and May^ that it is a Fossarus. It seems to me a 

 larval shell of the Siimsigera form. 



Crossea gatliffi, n.sp. 

 (Plate ii., fig. 25.) 



Shell small, thin, globose-conical, spire elevated, gradate, basal 

 funicle slightly developed. Colour white C? bleached). Whorls 

 four. Sculpture : last whorl with fine, close spiral threads of 

 which every fourth is larger; at irregular intervals incipient 

 varices traverse the whorl; on the penultimate whorl the spiral 

 sculpture is more coarse and distant. Umbilicus narrow, bordered 

 by a slight rib, which continuing to the anterior extremity is 

 there notched by the pseudocanal. Aperture oval, outer lip thin 

 and everted. Height 1-16, major diam. 1-1, minor diam. 094 mm. 



Hah. — With C. blconica: one specimen. 



Type.— To be presented to the Australian Museum. 



This species is named in honour of m}^ friend Mr. J. H. Gatliff, 

 of Melbourne. The thin shell, lack of longitudinal sculpture, 

 tabulated whorls, and feeble basal funicule distinguish it. C. 

 striata^ perhaps its nearest all}-, is much larger, with conspicuous 

 reticulate sculpture and a double umbilical rib. 



Teinostoma involuta, n.sp. 



(Plate iii., fig. 35.) 



Shell small, solid, globose, spire slightly exserted, umbilicus 

 broad and deep. Whorls 3^, divided by a deeply channelled 

 suture, rapidly increasing, last whorl broadening and descending 

 at the aperture. Sculpture : first whorl smooth, the rest carrying 

 a row of tubercles along the crown and basal edge, on the last 

 whorl about twenty above and fifteen below. The intervening- 

 space is obliquely traversed by fine, close irregularly waved riblets, 

 narrower than their smooth interstices; these may fork or end 

 abruptly, but at either end of their course usually unite in bundles 

 of twos or threes to form the upper or lower tubercle. Their
