COCCLLINA TASMAXICA, FdsbriJ, Sp. 



Afwia-a parva, Angas, var. tasmanica, Pilsbry, The Nautilus, 

 viii., 1895, p. 128 ; Xacella tasmanica, Tate and May, Proc. 

 Linn. .Soc. jST. S. Wales, xxvi., 1901, p. 411, pi. xxvii., f. 89- 

 90 ; Coccidina nie7-idio?ialis, Hedley, Mem. Austr. ]\Ius., iv 

 1902, p. .S31, f. 64. 



The presence of an inrolled often caducous apex directed the 

 assignment of this species to Coccidina, and as that genus liad not 

 been reported from Australasia, the shell was by one of us described 

 as new. Mr. W. L. May pointed out the similarity between JS^. 

 tasmanica and C. meridionalis. After interchange of specimens 

 we agree that they are identical. Mr. H. Suter, who holds a co- 

 type and joined in the discussion, arrives at the same conclusion. 

 The species has recently occurred in deep water off the New Zea- 

 land coast. 



MONILEA OLEATA, sp. nov. 



(Plate xxxvii., fig. 1). 



Shell rather large, thin, regularly turbinate, base tlattened, 

 periphery subangled, spire elevated. Whorls seven, gi'adually 

 increasing, regularly rounded except a narrow flat step below the 

 suture. Colour beneatli white, above pale cinnamon with darker 

 radial streaks on the last whorl. Entire surface glossy, as if well 

 oiled. Sculpture : closely scored by sharp spiral cuts, which are 

 deepest about the periphery, fainter midway up the whorl and 

 vanish from the base and from the first four whorls. On the 

 penultimate whorl between the insertion of the lip and the suture, 

 there are sixteen of these impressed spirals. The flat interspaces are 

 obliquely ci'ossed by faint irregular growth lines. Aperture veiy 

 oblique ovate, upper insertion carried far forward, connected with 

 the lower by a thin dull film of callus. Lip quite sharp, within a 

 white edge is followed by a brown border anfl that again bv a 

 nacreous layer. This seijuence again appears along tiie interior
