CuAMIDiE. 
Chama sinistroi'sa (Brocchi) = gryphina (Lam.) is distinct from the more 
common Mediterranean Ch. gryphoides (L.), not only by the apex being 
turned to the left, but also by differences in the hinge. Weinkauff, i. p. 161. 
MYTILACEA, Cuv. {Lucinaceay Ad.). 
[Lucinid.®. 
Lucina reticulata (Vo\\)—pecten of the authors on Mediterranean shells. 
Old specimens are more equilateral and less transverse, therefore scarcely 
distinguishable from the fossil L. squamosa (Lam.). — L. bo7'ealis (L.)=radula 
of Montagu and Mediterranean authors. — L. spinifet'a (Montagu) occurs in a 
smaller and larger form ; the latter =h{atelloides (Basterot), both recent and 
fossil. — X. lactea (lj.)=fragil{s (Phil.). — L. leucoma {Tmt.) =lactea of La- 
marck and most authors.~X. divaricata (h.) = commutafa (Phil.). — L. la^ 
mar chi (Bunker eoW.)— divaricata of Lamarck, is West Indian, and doubtful 
as Mediterranean. Weinkauff, i. pp. lGO-170. 
Lucina quadrisulcata (Orh.) = 07'nata (Reeve) =c6Mmca (Reeve), from the 
Bay do Castries. Schrenck, 1. c. p. 622. 
Ciyptodon sarsii (Phil.). The living animal and its anatomy is described 
at length by M. Sars. The mantle is open in front and below, united behind 
and provided with one circular opening ; its edges are simple, neither plaited 
nor provided with tentacles ; no siphons. Foot cylindrical, very long, ver- 
miform, subclavated at its end, hollow inside. Only two very small labial 
appendices, which are spirally twisted. Sexes separate. Vidensk. Selsk. 
Forhandl. 1864, pp. 1-15, pis. 4 & 6. 
\_C7'y}7todo7i] Axmus ahyssicolus (Forbes), from the yEgean Sea, is distinct 
from A. ferrugmosus of the same author and locality. Weinkauff, i. p. 172.

Mysia (JFela7iid) ada77isi andi jackso7iiensiS) spp. nn., Angas, Proc. Zool. Soc. 
p. 910, pi. 44. figs. 9 & 10, Port Jackson. — Diplodo7itaj sp., allied to coelata 
(Reeve as Lucina), from the Bay of Yedo. Lischke, Mai. Bliitt. xiv. p. 177, 
Kelliid^e (Laseidas). 
[Lasea'] Poro7iia r7ihra (Mont.) =i?orma se7nmulum (Phil.), Mediterranean. 
Its shape is somewhat variable. Five young shells were found in a speci- 
men. Weinkauff, i. p. 177. 
Bo7'7iia (Phil.). This genus is restored by Weinkauff, on account of the 
different aspect of the living animal from that of Kellia, for Philippi’s third 
species, B. co7'huloides (Phil.), which is identical with E7'ycina geoff7'07ji 
of Chenu (Manuel, fig. 394) and S. Wood’s fossil Lepton ddioidcum. The 
edge of the valves is crenulated in some recent specimens, in others this 
crenulation is obsolete or entirely absent. Weinkauff, i. pp. 178-180. 
• Kellia geoffro7ji (Payr. as Erychia) is a Mediterranean species, which has 
not yet been recognized. K. co77iplanata (Phil.) is perhaps the same species. 
K. suborbicularis (Mont.), Mediterranean specimens (=Bo7’nia mjiata, Phil.) 
remain much smaller than British. K. transversa (Forbes), from the ^gean 
Sea, is doubtful, perhaps a Mo7itacuta, Weinkauft) i. pp. 173-176. The
