able differences in this respect from the Heteropods, or from Phyllirhoe 
and Actoion.

Conus. H. C. Weinkauff has continued the monograph commenced by 
Kiister thirty-three years ago, in his 2nd edition of the conchological work of 
Martini & Chemnitz, parts 66 & 70, pp. 105-124 (old) 125-300 (new), pis. 
xix.-liii., with a critical review of the species hitherto described and 
figured in this work, and bringing their number up to 258. The following 
are new or not yet figured : — C. maltzani[an']us^ sp. n., p. 204, pi. xxxii. 
figs. 3-6, Tahiti \jichelii^ sp. n., p. 206, pi. xxxii. figs. 11 & 12, Massowah ; 
Icehheckeanus, sp. n., p. 221, pi. xxxvi. figs. 3 & 4, locality unknown; 
schech (Jickeli, MS.), sp. n., p. 229, pi. xxxvii. figs. 9 & 10, Red Sea. 
The synonymy of many known species is corrected. 
A systematic catalogue of recent species, with synonyms, quotations, 
and localities, is given by the same author in JB. mal. Ges. i. pp. 236-268 
& 273-288 ; he enumerates 362 species, arranged in 17 groups, the 
geographical distribution of which is sketched out, pp. 289-305. 
A list of 90 species from New Caledonia, with descriptions and figures 
of the opercula of many of them, is given by H. Crosse & Marie, 
J. de Conch, xxii. pp. 333-359, pis. xiii. & xiv. The operculum has been 
found in all species capable of examination, and is of essentially the 
same structure, but somewhat different in shape (straight or curved) 
and relative size ; in C. striatus (L.) and talipa (L.) it is very small. 
[According to specimens in the Berlin Zoological Museum, a small 
operculum exists also in C. geographus (L.), in which its occurrence 
was denied by Dr. Gray, Guide Moll. 1857, p. 5.] The living 
animals of C. tulipa and C. textilis (L.) sting, producing great pain and 
swelling.
