fifteen in number, smaller and more numerous on the umbones, gradually widening out 
on the body of the shell, and very widely separated on the posterior ends ; between the 
undulations are delicate striae. 
Obs. The coarseness of the concentric undulations brings this shell in close 
relationship with Qlycimeris sulcata, Eth., but it is much longer in proportion to its 
height than that species, with a longer anterior end, and a straighter hinge.

Sp. Char. Shell ovately oblong, moderately large, tumid, inequivalve ; umbones 
anterior, incurved, close ; anterior margin truncated, angular ; posterior end attenuated, 
rounded, widely gaping ; ventral margin slightly rounded ; surface of the shell with wide 
irregular lines of growth, the outer surface of the tost, where best preserved, showing 
it to be very wrinkled. It is three and a-quarter inches broad by two and a-quarterin 
height. {Moore.)

Sp. Char. Shell ovately elongated, thin, flattened ; umbones close, depressed, 
mesial ; anterior end rounded ; the middle of the valves with a depression or fold from 
the umbo, which widens to the ventral margin, surface with broad curved rounded 
costae. {Moore.) 
Obs. The posterior end of this figure, copied from Mr. Moore’s illustration 
(PI. 28, fig. 9) is wanting. 
The genus Goniomga made its first appearance in the Lias, but did not survive 
tbe Cretaceous Period.

Obs. Two specimens of this genus, in a micaceous sandy or arenaceo-ealeareous 
limestone, were examined by Mr. E. Etheridge, F.E.S., who remarked—” The absence 
of radiating costa;, and the somewhat wrinkled surface of the shell, as well as the position 
of the umbo and the gently curved hinge-line, favour the view that the two casts belong 
to the genus Ilomomya."
