though quite distinct, between C. Hedleyi and C. Syhenii, the former 

 being the most abbreviated, ventricose, and multicostate, the latter 

 the narrowest, most fusoid, and fewest ribbed. I cannot trace the 

 least resemblance, either, to an Ancistrosyrinx which Mr. Hedley 

 mentions exists in his C. vepratica. Doubtless C. asperulata,^ E. A. 

 Smith, from the North Arabian Sea, is likewise akin to these. 



It gives me much pleasure to name this species after my friend 

 Mr. Charles Hedley, who is prosecuting such successful researches 

 amongst the rich molluscan fauna of Australia and the South Pacific 

 Ocean.

I am grateful to Mr. E. R. Sykes for calling my attention to 

 this small Philine, which I had thought but a juvenile form of 

 P. orientalis, A. Ad., a species also occurring in the same seas. The 

 frontal projection of the outer lip is peculiar, and like no species 

 with which I am acquainted. The shagreened chain-like spiral 

 ornamentation, visible only with a very strong lens, resembles that of 

 other species. 1 have only seen two or three examples, all dead 

 shells, and some encrusted with Globigerince and other Foraminifera.
