LINGULA. 
: Puate II. 
Species 6. (Mus. Cuming.) 
LINGULA sEMEN. Ling. testd ovato-oblongd, crassius- 
culd, pland, albidd, levissimd, politd, limbo anteriore 
rotundato. 
Tue spep Line@ura. Shell ovately oblong, rather thick, 
flat, whitish, very smooth, polished, anterior edge 
rounded. 
Broverip, Pro. Zool. Soc. 1833, p. 125. 
Hab. Isle of Plata, West Columbia (dredged in fine coral 
sand, from a depth of seventeen fathoms); Cuming. 
My. Broderip thinks this may be a young individual, 
“but the shell is so much firmer than it usually is in Lin- 
gula (so firm, indeed, as not to have contracted at all in 
drying), that I cannot but look on it as an undescribed 
species. In size and appearance it bears a near resemblance 
to a melon-seed.” 
Species 7. (Mus. Cuming.) 
LinevuLa uirunvo. Ling. testd oblongo-quadratd, tenui, 
virescente, postice abrupte attenuata, umbonibus sub- 
acutis. 
THE swaLLow Lineuta. Shell oblong-square, thin, green- 
ish, posteriorly abruptly attenuated, umboes rather 
sharp. 
Hab. Port Curtis, north-east Australia; Stutchbury. 
Several specimens of this little semitransparent species 
were collected by Mr. Stutchbury at the above-named 
locality. 
Species 8. (Mus. Cuming.) 
Lineuta ANTILLARUM. Ling. testd oblongo-ovatd, an- 
tice subquadratd, albidd, cerulescente-viridi, versus 
umbones pallide tinctd, valvis undique clausis. 
Tue West Inpran Lincuua. Shell oblong-ovate, some- 
what square anteriorly, faintly tinged with blue-green 
towards the umboes. 
Hab. Martinique (dredged at a depth of sixteen fathoms). 
Of this small species from Martinique, Mr. Cuming 
has orly a single specimen. It appears to be distinct, and 
the habitat is peculiar. 
Species 9. (Mus. Cuming.) 
Lingua pxusta. Ling. testé oblongo-ovatd, tenuiculd, 
rufescente-luted, versus marginem intense fuscatd, ni- 
tente, umbonibus subacute rostratis. 
Tue swartHy Lineuta. Shell oblong-ovate, rather 
thin, reddish-yellow, deeply stained with brown to 
wards the margin, shining, umboes rather sharply 
beaked. 
Hab. Moreton Bay, Australia; Strange. 
If L. Murphiana be an Australian form of LZ. anatina, 
this might be regarded as the representative in the same 
locality of Z. hians. Both species exhibit a peculiar cop- 
pery-redness, heightened in this to a dark, shining, swarthy 
tone of colour. 
Species 10. (Fig. 10 and 11, Mus. Cuming.) 
Lineuua anatina. Ling. testé oblongd, anticé rotun- 
dati, posticé attenuata, wmbonibus subrostratis, intense 
viridi, valvis utrinque clausis. 
THE DuUCK’s-BILL LincuLa. Shell oblong, rounded at 
the anterior end, attenuated at the posterior, where 
the umboes are somewhat beaked, bright-green, 
valves closed on each side. 
Lamarck, Anim. sans vert. vol. vii. p. 390. 
Rostrum anatis, Petiver. 
Patella unguis, Linneeus. 
Pinna unguis seu lingua, Chemnitz. 
Mytilus lingua, Dillwyn. 
Hab. Molucca and Philippine Islands. 
This well-known species having been described by 
Petiver as the Duck’s-bill, Rostrwm anatis, before Lin- 
neus erroneously named an odd valve of it as a Patella, the 
Lamarckian application of the original title to the bino- 
mial form of nomenclature may take precedence. 
Mr. Cuming happened to be at Manilla in 1836, after 
an unusually boisterous typhoon, when as many as twenty 
bushels of this species were collected on the shores of the 
Bay ; and he procured more than a hundred new species 
of shells on this occasion which he never met with again. 
Species 11. (Fig. 12a, 6, Mus. Cuming.) 
Lineuta urans. Ling. testa elongato-ovatd, posticé sub- 
acute attenuata, tenui, utringue hiante, pallide vires- 
cente, uimbonibus acute rostratis. 
THE Gapine LineuLa. Shell elongately ovate, rather 
sharply attenuated posteriorly, thin, gaping at both 
ends, pale-green, umboes sharply beaked. 
Swainson, Zool. Illus. vol. ii. pl. 2. 
Hab. China. 
The gaping of this species does not appear to depend 
upon the drying of the shell; it always dries into a gaping 
attitude, which is not the case with other species.
