This shell, figured in Delessert’s ‘ Recueil de Coquilles,’ pl. 4: f. 1, 
a, 6, is extremely rare. The only specimens I have seen are in the 
collections of Miss Saul and the Rev. Mr. Stainforth.

8. CrassaTELLA ANTILLARUM. Crass. testi trigono-ovaid, vix 
gibbosd, crassd, epidermide fibrosd indutd ; intits brunned, prope 
ad marginem albicante ; umbonibus subdepressis, leviter undulatis ; 
latere antico rotundato, postico subungulato. Reeve, Conch. Icon.

Hab. ad insulam Margaritta, Antillarum. 
Mr. Cuming informs me that this beautiful species was dredged 
up in the pearl-fisheries at the island of Margaritta in the West 
Indies. It is erroneously figured in Delessert’s ‘Recueil: de Co- 
quilles’ as the Crassatella rostrata of Lamarck. ‘The rich chocolate 
colour of the interior of this shell is very remarkable, approaching 
somewhat in that respect to that of the preceding species. 
9. CRAssaTELLA JuBAR. Crass. testd subovatd, vald? inequilaterd, 
gibbosd, extis vivide radiata, radiis ferruginosis, ab umbonibus, 
jubarum similitudine, divergentibus ; ad utrumque latus irregulari- 
ter multistriata ; epidermide fusca, subquassd, sparsim indutd ; in- 
tis alba, ad extremitatem posticam brunned ; umbonibus plicatis, 
compressis ; latere antico inclinato, rotundato, postico arcuato, 
elongato, acuminato. Reeve,Conch.Icon.Crassatella, pl. 2. f. 11. 
Long. 23; alt. 13 poll. Mus. Cuming. 
Hab, Ad oras occidentales Nove Hollandiz. 
A single specimen of this fine shell was procured by Mr. Cuming 
in Hamburgh ; it had been received from that prolific portion of the 
globe above noted, and has made a valuable addition to the genus. 
It has the general form of the C. gibbosa; the sides are profusely 
striated, and the entire surface is richly illumined with brownish rays, 
diverging like solar beams from the umbones to the margin.

p- 481; Reeve, Conch. Icon. Crassatella, pl. 2. f. 6. a. and 6. 
Hab. ad oras Nove Hollandie. 
This is another very rare species; I know of two or three odd 
valves, but only one true pair, which is in Mr. Cuming’s collection.

The figures which have been just published by M. Chenu in De- 
lessert’s ‘Recueil de Coquilles’ as the Crassatella rostrata of Lamarck, 
are certainly not that species, nor do they at all correspond with his 
description of it, particularly in that part which says intis margine 
crenulato ; | have moreover every reason to believe that they are 
drawn from specimens of the new species from the island of Marga-
