TELLINA. 
PuatE XXVI. 
Species 6. (Fig. 4, c, Mus. Taylor.) 
TELLINA MAGNA. This grand orange-bordered variety 
having arrived too late for insertion with the de- 
scription of the species, it is now presented to com- 
plete our illustration. 

Species 138. (Mus. Taylor.) 
TRLLINA ExcavaTa. Tel. desta solidd, altd, subrotundda, 
albidé, ad umbones roseo tinctd, concentricé minute 
rugatd, radiatim minutissime striata ; latere postico 
brevi, obtuse angulato, post anguluim fleauoso, ante an- 
gulum depresso, margine dorsali declivi, prope um- 
bones inflexo, profunde excavato, termino subtruncato, 
margine ventrali ad angulum flexuosa, sursim ac- 
clivi; latere antico ventricoso, obliqué elongato, ro- 
tundo, margine dorsali declivi, cardine trigono, den- 
tibus lateralibus nullis. 
THE EXCAVATED TELLINA. Shell solid, elevated, rather 
round, white, tinged with rose at the umboes, con- 
centrically minutely wrinkled, radiately very minutely 
striated; posterior side short, obtusely angular, 
flexuous behind the angle, depressed in front of the 
angle, dorsal margin sloping, bent inwards, deeply 
excavated near the umboes, subtruncated at the end, 
ventral margin flexuous at the angle, sloping up- 
wards ; anterior side ventricose, obliquely lengthened, 
rounded, dorsal margin sloping, hinge trigonal, no 
lateral teeth. 
SOWERBY. 
Hab. 
A much more solid and less ventricose shell than 7d- 
lina ephippium, and without the elevated posterior angle 
of that species.

Species 139. (Fig. a, 6, Mus. Taylor.) 
TELLINA INmHQUIVALVIS. Tel. testa albd, compressd, 
ovata, inequilaterali, prope marginem ventralem mi- 
nuté concentricé rugatd, valeuld deatrad quam sinistra 
mayis profunda, ad marginem ventralem postice eandem 
superante ; latere postico compresso, lateraliter fleru- 
oso, margine dorsali declivi, ared impressd postangu- 

lari, subalato, termino acuminato, margine ventrali 
sursum acclivi ; latere antico suboblique producto, in- 
flato, termino rotundo, dentibus lateralibus anticis ad 
umbones proxinis. 
THE INEQUIVALVE TELLINA. 
oval, inequilateral,, minutely concentrically ridged 
Shell white, compressed, 
near the margin, left valve deeper than the right, 
overlapping it at the posterior ventral margin; pos- 
terior side compressed, laterally bent, dorsal mar- 
gin sloping, partly winged, with an impressed post- 
angular area, acuminated at the end, ventral margin 
sloping upwards; anterior side subobliquely pro- 
duced, inflated, rounded at the end, anterior lateral 
teeth near the umboes. 
SOWERBY. 
Hab. Moreton Bay, Australia. 
A very curious species, having one valve deeper than, 
and at the ventral margin overlapping the other. 

Species 140, (Mus. Taylor.) 
TELLINA ALTA. 
oblique retrorsd, altd ; latere postico brevi, margine 
Tel. testa alba, inflata, tenut, levigatd, 
dorsali valde declivi, prope umbones excavato, termino 
trunecato, angulatim flecuoso, ad angulum subduplica- 
tim elevato et depresso, margine ventrali sursiim ac- 
clivi, versus medium rectiusculo ; latere antico inflato, 
valde declivi, margine ventrali subquadrato, dentibus 
lateralibus nullis. 
ELEVATED TELLINA. Shell white, inflated, thin, 
smooth, obliquely leaning backwards, elevated; pos- 
Tur 
terior side short, dorsal margin very sloping, exca- 
vated near the umboes, truncated at the end, angu- 
larly flexuous, with a partly duplicate elevation and 
depression at the angle, ventral margin sloping up- 
wards, rather straight towards the centre; anterior 
side inflated, very sloping, ventral margin rather 
square, no lateral teeth. 
Conrap, Journ. Acad. Phil. 
Hab. California. 
A more elevated and less sloping shell than Tel/ina 
angulata.
