FISHES, ETC. OF THE ‘NASSAU’ VOYAGE. 497 
little more than an inch. Named in honour of Nav. Lieut. F. G. Gray, R.N., who 
was of material assistance to me in my dredging operations. 
54. RHYNCHOCINETES TYPUS, Edw. 
I obtained many specimens of this fine Crustacean in rock-pools at Coquimbo at low 
tide. It is an exceedingly beautiful creature when alive, the body and legs being 
elegantly mottled and banded with various shades of red and brown. 
55. PALAMON FORCEPS, Edw. 
This species is the prawn so largely sold in the market at Rio de Janeiro, in the har- 
bour of which it is taken. 
56. PALÆMON CÆMENTARIUS, Pœppig. 
I procured five examples of this large species, termed “Camaron ” by the Chilians, 
and esteemed by them as a great delicacy, in freshwater marshes between the town of 
La Serena and the sea. In Gay's ‘Historia Fisica y Politica de Chile’ we are informed 
that it is to be found “en los embocadores de las riveras donde construyer de grandes 
cavidades que cubre con tierra,” 
STOMAPODA. 
57. MACROMYSIS MAGELLANICA, Sp. n. 
General form that of M. gracilis, Dana (from Rio de Janeiro). Cephalic portion of 
carapace partially separated by a suture from the remainder. Rostrum as in M. 
gracilis. Segments of pleon about as long as broad, with the exception of the sixth, 
which is almost twice as long. Terminal segment of pleon deeply bilobate. Taken 
at the eastern entrance of the Strait of Magellan, January 1867. 
58. PHYLLOSOMA, Sp. 
A very small species of this genus, which I consider more prudent to leave undeter- 
mined, was taken in the towing-net between the river Plate and the Strait of Magellan, in 
November 1867. | 
59. ALIMA HYALINA, Leach. 
Taken in the towing-net to the south of the Cape-Verde Islands,

end of August 1868. j |

Common on the sandy beach of San Carlos de Ancud, Chiloe, where it skips about 
after the manner of our common Sandhopper ( Talitrus locusta).
