176 MR. G. F. ANGAS ON THE MARINE [Jan. 24, 
Phasianella bulimoides, Lam. 
P. varia, Encye. Méthod..pl. 449. f. 1. 
P. picta, De Blainville. 
P. australis, Deshayes. 
Station. On sandy bottoms, amongst the vast meadows of Zostera 
that fringe the Laminarian zone. 
Hab. St. Vincent’s and Spencer’s Gulfs. 
This is the largest species known, and its variations of painting, in 
pattern and colour, are endless. Mr. Reeve’s P. venusta is, 1 am 
pretty certain, only an ordinary variety of Hutropia tritonis. The 
species ranges from Swan River eastward to Port Phillip and West- 
ern Port; but in St. Vincent’s Gulf, where it is very abundant, it 
appears to attain its extreme development, both as regards size and 
variety of markings. When the living shell is first taken from the 
water, nothing can exceed the depth and brilliancy of its colours ; 
but after the animal is removed, and the shells are exposed to the 
air, they fade rapidly—more so, indeed, than those of any other 
mollusk with which Iam acquainted. Although hundreds of bushels 
of these shells are cast on shore after a gale of wind, and many of 
them contain living animals, it is difficult to meet with a single per- 
fect specimen, the delicate outer lip being generally fractured.
