FISHES, ETC. OF THE ‘NASSAU’ VOYAGE. 479 
TURRITELLIDA. 
39. SCALARIA MAGELLANICA, Phil. 
A single specimen of this species was procured in the Strait. 
CERITHIIDA. 
40. CERITHIUM PULLUM, Phil. 
Several specimens of a mollusk referable, I believe, to the above were dredged in the 
Strait. 
LITTORINIDÆ. | 
41. LITTORINA STRIATA, King. 
This species was common in the rock-pools at St. Vincent. 
42. LITTORINA FLAVA, Brod. 
Common on the rocks above high-water mark at Rio de Janeiro. 
43. LITTORINA ZEBRA, Wood. 
This pretty little species was met with very plentifully on the rocks at high-water 
mark in Valparaiso and Coquimbo Bays. 
PALUDINIDE. 
' 44. AMPULLARIA FASCIATA, Reeve. # 
I found a number of specimens of dead shells of this species floating in a marsh at Mal- 
donado, as well as some clusters of its beautiful pink eggs attached to growing reeds. 
TURBINIDÆ. 
45. MARGARITA VIOLACEA, King. 
This pretty little species is very common alike in the eastern and western parts of the 
Strait of Magellan, and also in the channels. The Fuegians make necklaces of it by 
drilling holes through the shells and stringing them together with sinews. It is often 
to be found on Macrocystis. 
46. MARGARITA CARULESCENS, King. 
This species, much larger than the former (I have met with specimens nearly an inch 
in diameter), is also very common in the Strait, and apparently also on the Patagonian 
coast north of the Strait, as I procured it at the mouth of the Gallegos river. 
47. MARGARITA TÆNIATA, Sw. E 
I procured this species at the Falkland Islands, and also in the Strait, where, however, 
it does not appear to be nearly so common as the two former. 
48. CHLOROSTOMA BICARINATUM, Pat. & Mich. 
A specimen of this species was dredged in Herradura Bay.
