FISHES, ETC. OF THE ‘NASSAU’ VOYAGE. 477 
26. CONCHOLEPAS PERUVIANA, Blainv. 
This curious species is abundant on the Chilian coast, adhering with great tenacity to 
the rocks in the Laminarian zone. It is regarded as a delicacy by the Chilians, by whom 
it is termed * Loco." I never met with live specimens to the south of Chiloe, but was a 
good deal puzzled by picking up two worn, dead shells close to Fuegian encampments in 
the channels on the west coast of Patagonia. One of these occurred at Port Grappler, 
opposite the south-east corner of Saumarez Island, and the other at Puerto Bueno, at 
_ the northern part of the Sarmiento Channel. I find it stated in the * Voyage of the Ad- 
venture and Beagle,’ vol. i. p. 167 (Captain Stokes's narrative), that at Port Santa 
Barbara, at the northern extremity of the Island de Campanha, situated outside Wel- 
lington Island, to the south of the Gulf of Peñas, “the shells ( Concholepas peruviana) 
used by the Magalhaenic tribes as drinking-cups were found adhering to the rocks in 
great numbers." This refers to one of the habits of the Fuegian Indians never observed 
by us during our sojourn in the Strait and channels, though we had frequent opportuni- 
ties of holding intercourse with them ; and it is the only reference to such a custom with 
which I am acquainted. Did the mollusk still exist in the Strait and channels, 1 think 
it is hardly conceivable that it should have escaped my observation, as I carefully ex- 
amined all the Fuegian encampments and wigwams which we came across ; but never, save 
in the two instances I have mentioned, did 1 meet with a fragment of the shell. It is 
possible that at one time the animal may have existed in these regions, and have been 
extirpated in consequence of being a favourite article of diet, and that the drinking-cups 
alluded to by Captain Stokes may have been heir-looms handed down through several 
generations. 
27. MONOCEROS GLABRATUM, Lam. 
This species was met with plentifully at Lota, Bay of Arauco, and also at Chiloe. Dead 
specimens were also found in the Strait of Magellan.

This species was found at Columbine Cove,

Fine specimens of this species were taken on the rocks at St Vincent and at Rio de 
Janeiro.
