478 DR. R. O. CUNNINGHAM ON THE REPTILES, 
a great number of specimens, and found others burrowing in the sand at low-water mark. 
One animal, on being handled, discharged a pale yellowish fluid (like that secreted by 
Purpura lapillus), which changed after a time, on exposure to the air, to a beautiful 
purple tint which stained my fingers. 
CoNIDZ. 
32. CONUS, sp. 
A live specimen of a small species of the genus was taken at St. Vincent. 
VOLUTIDA. 
39. VOLUTA (SCAPHA) COLOCYNTHIS, Sw. 
I picked up a dead shell of this species on the sandy beach at Maldonado, on the north 
bank of the river Plate; and many live specimens were subsequently obtained by the 
officers of H. M. S. * Narcissus.’ 
34. VOLUTA (SCAPHA) MAGELLANICA, Gm. 
This Volute occurs very plentifully in the Strait of Magellan; but I never Rer in 
dredging a live specimen, which greatly perplexed me for a time. I, however, found two 
live individuals at low-water mark, and subsequently obtained numbers on the beach at 
Sandy Point, after a severe easterly gale; and this led me to the conclusion that the 
species lives in the sand just below low-water mark. 
35. VOLUTA (ScAPHA) Ferussac, Donovan. 
I met with the dead shells of this species in hundreds on the gravelly beaches at the 
eastern entrance of the Strait, but only once succeeded in procuring live specimens. These 
were found burrowing in the sand at low water at Cape Possession, on the Patagonian 
shore of the Strait. A few also were met with apparently feeding on the clusters of the 
Mytili attached to the rounded boulders on the beach. The foot of the animal is very 
large, and of a beautiful purple tint. Several of the specimens, which were kept tied up 
in a pocket-handkerchief for two days and a half, while I was detained on shore by a gale, 
were alive when 1 got on board. 
36. MITRA, sp. : 
A small species of this genus was procured at St. Vincent. 
NATICIDE. 
37. NATICA, sp. 
38. NATICA, sp. 
Two species of this genus, one with a horny and the other with a del operculum, 
were dredged in the eastern part of the Strait of Magellan.
