DESCRIPTION OF SEVERAL NEW SHELLS, AND REMARKS 
ON OTHERS, CONTAINED IN THE COLLECTION OF THE 
LATE MRS BLIGH. 
By WILLIAM SWAINSON, F.RS., &c. 
HALIOTIS GLABRA. 
(Lot 30 and 405.) 
H, (div. 2.) testd obtusé ovatd, depressd, latd, obsolete striatd, intis 
levi; spird ampld ; labio exteriore rotundato, margine antico gibbo; 
foraminibus minimis, numerosis, ovatis, sub-levibus. 
Shell obtusely oval, depressed, broad, obsoletely striated, within 
smooth ; spire ample; exterior lip rounded, the top gibbous ; 
perforations minute, numerous, oval, and nearly smooth. 
In this intricate genus, HH. G/abra cannot be mistaken. 
The perforations are even smaller than in Haliotis Californi- 
ensis (Zool. Ill. pl. 80.), though this character is partially 
destroyed when the shell is uncoated. It is a native of the 
coast of New Holland ; and is sometimes beautifully marbled 
with large angular veins of chesnut brown on a pale ground 
of greenish. |
