THE CATERPILLAR Curron. Shell somewhat elongately 
-ovate, valves very finely ridged throughout, ridges 
narrow, slightly waved, interstices peculiarly crenu- 
lately latticed, umboes of the valves pinched and 
sharply erect, posterior terminal valve small, umbo- 
nated to the extremity ; ligament slit at the posterior 
end, arenaceously coriaceous, brown. 
Hab. Sydney, New Holland; Jukes. 
An extremely interesting species, in which the umboes 
have a pinched erect growth, and are prickly-pointed ; it 
is altogether a most distinct species.

Curron Watsont. Chit. testd oblongo-ovatd, valvis omni-

Watson’s Carron. Shell oblong-ovate, all the valves 
smooth and finely engraved, the grooves radiating 
from the umboes, lateral areas but little raised ; olive 
or reddish-brown, sometimes concentrically splashed 
with pale green, umbonal eminence blackish-brown ; 
ligament horny, brown, furnished with very short 
bristles, with tufts of black curled hair at the lateral 
interstices of the valves.

Hab. Cape of Good Hope. 
This species varies in colour from a deep reddish mahog- 
any brown to an olive-brown, more or less variegated 
with concentric splashes of light green, the umbonal 
eminence being always darkened with a series of longitu- 
dinally triangular spots of much darker brown, nearly 
black ; the lateral interstices of the valves are mostly filled 
with rude tufts of harsh curled bristly hair.
