Yermicularia deposita, n.sp. 

 (Plate xli., fig.61.) 



Shell small, coarsely irregularly radiately ribbed. CoQimences 

 with a tvvo-vvhorled protoconch like V. caperata,'^ which it 

 envelopes, then extends in three or four loose advancing pros- 

 trate coils, finally rising free and erect for a short length. 

 Diameter of tube 0*7 mm. Length of coil 4; breadth 2-5 mm. 



A few dead and bleached specimens from 5-10 fathoms, I] ope 

 Island. 



Epitonium koskinum, n.sp. 



(Plate xl., figs.59-60.) 



Shell minute, conical acuminate, imperforate base flattened. 

 Colour cream. Whorls eight, including a subulate protoconch 

 of four smooth whorls. Sculpture : about ten prominent radial 

 ribs traverse the whole whorl, both ribs and interstices being 

 crossed by fine close punctate grooves. Aperture subcircular, 

 externally margined by a varix. Length 2-15; breadth LO mm. 



A few specimens from 5-10 fathoms, Hope Islands. Probably 

 the species attains a larger growth than my specimens represent. 

 Scalaria cerigottana Sturany,t appears to be very like, but it is 

 improbable that it should occur both in the Eastern Mediterra- 

 nean and on the coast of Queensland.

 Conch. Cab. iv., PI. 157, f. 1493-4; Pyramidella maculosa Forbes,

Occurred alive in the sandy mud round Hope Island. The 

 only reference to this species as Australian, is Forbes' note of it 

 from the islets of Trinity Bay, a little south of our station.
