CHAMA.—Puate IX. 
THE LITTLE Box CuHAmA. Shell orbicular, deeply sinu- 
ated on the posterior side, both valves peculiarly 
rudely lamellated and scaled, scales at the margin 
somewhat produced, but appressed, margins of the 
valves smooth; whitish, variegated with rose brown, ~ 
interior white. 
Hab. Honduras; Dyson. 
The upper valve of this shell is rather more convex than 
usual; the sculpture peculiarly rudely developed. 
Species 52. (Mus. Cuming.) 
CHAMA TUMULOSA. Cham. testd orbiculari, posticé subpro- 
fundé sinuatéd, valvis ambabus valde convewis, rude 
tumulosis et imbricatis, interstitiis posticé oblique lira- 
tis, liris minutissime squamatis, valvarum marginibus 
levibus ; aurantio rufoque varia, Uiris posticis albis, 
intus alba. 
THE TUMULOUS CHAMaA. Shell orbicular, somewhat 
deeply sinuated on the posterior side, both valves very 
convex, rudely tumulous and imbricated, posterior 
interstices obliquely ridged, ridges very minutely 
scaled, margins of the valves smooth; variegated with 
red and orange, posterior ridges white, interior white. 
Hab. Honduras (attached to coral); Dyson. 
A striking species though of rude growth; it is doubly 
sinuated on the posterior side, having round orange protu- 
berances along the summit, whilst the channelled inter- 
stices have a striped appearance from their being crossed 
by white ridges on a blood-red ground. 
Species 53. (Mus. Cuming.) 
CHAMA LINGUA-FELIS. Cham. testd orbiculari supra 
depressiusculd, valvis ambabus precipue inferiore minute 
retusé squamatis, superiore pulcherrime fimbriato-lami- 
naté, laminis appressis, postice concavo-planatd, ad 
angulos elongato-lamellatis, valvarum marginbus levi- 
bus ; nived, rosaceo hic illic tincté. 
THE cCaT’s-TONGUE CHamMa. Shell orbicular, rather 
depressed, both valves, especially the lower, covered 
with minute blunt scales, upper valve very beautifully 
fimbriately laminated, laminee appressed, posteriorly 
concavely flattened, elongately laminated along the 
angles, margins of the valves smooth ; snowy white, 
stained here and and there with rose-pink. 
Hab. Island of Guimaras, Philippimes (attached to stones) ; 
Cuming. 
An extremely delicate and characterstic species in which 
the upper valve is very finely laminated, whilst the ground 
sculpture of both that and the lower valves is of a curious 
roughened character somewhat similar to the Telline scobi- 
nata and lingua-felis. 
Species 54. (Mus. Cuming.) 
CHAMA PELLIS-PHOcE. Cham. testd suborbiculart, valva 
superiore undique minutissime squamatd, sqyuamis umbo- 
nem versus brevissime retusis, marginem versus longio- 
ribus subspiniferis, inferiore rude lamellatd, valvarum 
marginibus levibus; alba, squamis marginem versus 
rufo-fuscis, umbone roseo. 
THE SEAL-SKIN CHama. Shell scarcely orbicular, upper 
valve very minutely scaled throughout, scales very 
short and blunt near the wnbone, longer and some- 
what spinous towards the margin, lower valve roughly 
lamellated, margins of the valves smooth; white, 
scales towards the margin reddish brown, umbone 
pink. 
Hab. Island of Ticao, Philippines (attached to stones); 
Cuming. 
The pink stain upon the umbone is probably a character 
which may help to distinguish this species. 
Species 55. (Mus. Cuming.) 
Cuama appressa. Cham. testa orbiculari, valvis amba- 
bus concentricé laminatis, laminis tenwbus plano-ap- 
pressis, inferiore posticé liris perpaucis minutis oblique 
exsculptd, valvarum marginibus levibus; alba, roseo- 
Sfuscescente sparsim tinct. 
Tur apPRESsED Cama. Shell orbicular, both valves 
concentrically laminated, laminz thin, flatly appressed, 
lower valve obliquely sculptured on the posterior side 
with a very few minute ridges; white, sparingly 
tinged with rose-brown. 
Hab. Honduras; Dyson. 
Distinguished by its concentric flatly appressed lamine-
