Trttina RuGosA. Tel. testa subovatd, crassa, ventricosa, 
omnino rugis crassis undulatis disruptis exasperatd,

ROUGH TELLINA. 
roughened all over with undulating, thick, broken-up 
THE Shell subovate, thick, ventricose, 
wrinkles, nearly equivalve, inequilateral, posterior side 
acuminated, plaited with a large oblique rib; with 
the dorsal margin short, sloping, rather straight, ob- 
liquely subtruncated at the end, area behind the fold 
in the right valve rather flattened, ventral flexure 
large, anterior side rather round, dorsal margin 
slightly sloping, deeply excavated near the umboes, 
ligament large, partly imbedded, umboes subcentral, 
unequal, lateral teeth strong, nearly equidistant.

The differences in texture between the two specimens 
we have figured would be almost sufficient to justify their 
specific separation, did we not know that throughout the 
genus similar variations take place in shells of the same 
species.

Tue FiesHy Teiutna. Shell suborbicular, inequilateral, 
equivalve, flesh-coloured, concentrically banded with 
red, minutely obliquely and angularly striated, middle 
striz generally more distant, forming a very acute, 
inverted angle with the posterior striz, anterior strize 
forming an obtuse angle with those of the centre, 
posterior strize very fine, obliquely sloping upwards, 
posterior side oblique, subacuminate, slightly plaited, 
with dorsal margin sloping, anterior side short, rather 
angularly rounded, umboes round, lateral teeth sinall, 
rather near.

THE SELENDID TELLINA. Shell orbicular, solid, subin- 
equivalve, inequilateral, convex, yellowish-white, near 
the umboes tinged with bluish or purple, banded in 
the centre, ridged in front with thick concentric 
wrinkles, obliquely striated in the middle, and pos-

In its general aspect this species resembles Tedlina Se- 
negalensis, but it is in the first place rather less oblique
