1862.] MR. A. ADAMS ON NEW SPECIES OF LIMOPSIS. 229 
5. Descrirtions oF somr New Species or Limorsis FROM 
THE CUMINGIAN CoLLecTION. By ArtHurR Apams, F.L.S. 
There have been six recent species of Limopsis already described, 
nemely, L. multistriata, Forsk.; L. belcherit, Adams & Reeve; L. 
cancellata, Reeve; L. borealis, Woodward; L. pygmea, Phil.; and 
L. oblonga, A. Adams. To these I now add five more recent species 
from the seas of Japan, one from the Cape, and two from Lizard 
Island in Torres Straits. Those from Japan and the Cape were 
obtained by myself; and for the Australian examples we are indebted 
to Mr. Macgillivray. Nearly all the known species are in the mag- 
nificent collection of Mr. Cuming. 
1. Limopsis saponica, A. Adams. 
L. testa orbiculari vie equilaterali, albida aut rufescente, costel- 
lis radiantibus striisque elevatis concentricis concinne cancel- 
lata, epidermide fusca dense pilosa, pilis in fimbriis concentricis 
dispositis, obtecta, intus rufo-fusca, radiatim strigosa, albo 
marginata ; margine ventrali explanato, intus integro, 
Hab. Kuro-Sima, 57 fathoms; Kiusu, 26 fathoms. 
This species in form and sculpture most nearly resembles Pectun- 
culus cancellatus of Reeve, which is a true Limopsis. It is, how- 
ever, much larger, the radiating ribs are equal, and the hinge-margin 
is not straight, and is extended in the form of auricles. 
2. Limopsis osptiqaua, A. Adams. 
L. testa valde obliqua, oblonga, inequilaterali, tumidula, albida, 
longiore quam lata, latere antico brevi, postico longiore, ra- 
diatim striata, liris crenulatis concentricis decussata, epidermide 
dense pilosa fusca obtecta ; linea cardints arcuata, fessa magna 
triangulari; intus alba vadiatim strigosa, margine ventrali intus 
levi. 
Hab, Uraga, 21 fathoms. 
This species is even more oblique than ZL. oblonga, A. Ad. (Ann. 
and Mag. Nat. Hist. 1860), from which it differs in being oval, and 
not trigonal, in the broad triangular cartilage-pit, and in the ventral 
margin not being internally crenate. 
3. Limopsis cuminel, A. Adams, 
L. testa ovata, valde obliqua, inequilaterali, latiore quam longa, 
compressa, albida, concentrice lirata, interstitiis longitudinaliter 
radiatim striatis, latere antico brevi, postico multo longiore 
dilatato, epidermide pilosa pailide fusca, pilis in fimbriis con- 
centricis dispositis, oblecta, intus alba, margine ventrali intus 
levi. 
Hab. Gotto, 48 fathoms; Santanomosaki, 55 fathoms. 
This species somewhat resembles Z. belcheri in form, but the 
posterior side is regularly arcuate, and the hinge-margin is bent in 
the middle; the teeth, moreover, are much less numerous, and the 
ventral margin of the valves is not crenate within.
