 Ceritkium, plates 11 to 20; completing the monograph. Oct. — 

 Dec, 1865. 



There are included in this genus, excluding Vertagus and 

 Gerithiopsis, but embracing Bittmm, one hundred and forty- 

 nine species. The following are described as new : — 



We notice, that in two cases, localities are given incorrectly, 

 in ascribing to the United States species which are far-distant 

 in their habitat. Thus, G. Janthinum, " Clermont-Tonerre, 

 (Island) U.S.," and G. lacertinum, "Sydney Ilarbor, U. S." 

 The latter species was collected at Sydney, New South Wales, 

 by Dr. Wm. Stimpson, and Dr. Gould has appended the ini- 

 tials W. S. to the locality, as authority for it. Mr. Sowerby 

 has, perhaps, thought W. S. an error for U. S.
