brazier: cypR/Ea found in moreton bay. 319 



were found on the beaches at Lake Macquarie, 70 miles 

 north of Port Jackson, not a single specimen of C. caput- 

 serpentis was found. 



During an extended trip of six months from the Manning 

 River, including the Macleay, Nambucera, Bellenger and 

 Clarence River, with all intermediate small bays, creeks and 

 headlands, C. caput-angids is the predominent species, very 

 few of C. capitt-serpentis obtained. Some years ago I quoted 

 C. capiit-a?iguis as C. caput-serpentis, the former is very rarely 

 to be found in a living state on the coast of New South Wales. 

 I quite agree with Mr. A. Garrett, who is a close observer of 

 genus, that it is a distinct species and need not ever be 

 confused with C. caput-serpeniis. 



In some papers that I have from the late Mr. Harper 

 Pease, reprints from American Journal of Conch., v., p. 85, 

 the description of the animal differs a little from that given 

 by Mr. Garrett. I give Mr. Pease's own words — "Compared 

 with capui-serpentis^ it is smaller in size, not dilated at the 

 sides, darker in color throughout, and dorsal spots smaller. 

 The only description of the animal oi caput serpentis published 

 so far as I can discover, is that in ' Voy. d' Astrol.,' from 

 which caput-aiiguis differs as follows: — Mantle of a deep 

 brown, shaded with dark green, its tentacular processes red 

 or red and white. Siphon dusky, tentacles beyond the eyes 

 light chestnut, base white. Foot pale beneath, dusky above. 

 The tentacular fringe surrounding the end of the siphon is 

 retractible. The colors and their arrangement agree with the 

 type, only darker." Mr. A. Garrett's description — "The 

 animal has a dark brown mantle, varied with dark green, and 

 garnished with red or red and white, more or less divided 

 processes. The siphon is dusky-slate, tentacles brown with 

 white bases, and the foot dusky-slate with a paler creeping 

 disk.
