FISHES, ETC. OF THE *NASSAU' VOYAGE. | 495 
38. HIPPA EMERITA, Linn. 
Many specimens of this species were taken in Five-fathom Bay, Rio de Janeiro, in 
October 1867. 
39. HIPPA TALPOIDES, Say. 
Common on the coast of Chili. Specimens were found at Ancud (Chiloe), Luco Bay 
and San Vicente, near Talcahuano. 
40. PAGURUS FORCEPS, Edw. ? 
A Pagurus which I refer with some doubt to this species is very common in the 
Strait of Magellan and western channels. 
41. BERNHARDUS OBESO-CARPUS, Dana. 
This species was obtained at Coquimbo. 
42. PORCELLANA TUBERCULATA, Guérin. 
Common in the rock-pools at Coquimbo. 
43. PORCELLANA VALIDA, Dana. 
Abundant at Ancud (Chiloe), and taken also at Lota. 
44. PORCELLANA TUBERCULIFRONS, Edw. and Luc. 
Very common under stones in rock-pools at Coquimbo, and taken also at Chiloe. 
45. PORCELLANA PATAGONICA, n. Sp. 
Length and breadth of carapace about „5; of an inch. Fronttrilobate ; the middle lobe 
much projecting and pointed; all three lobes minutely crenulated on the margin. 
Carpus not dilated in front or behind, with three prominent teeth nearly of equal 
size on the anterior margin, and a tooth at the outer side of the articulation with the 
hand. All the legs minutely granulated; the first pair slightly crested on the anterior 
margin. Carapace smooth on the centre, minutely granulate on the sides. 
This species, which appears to me to be undescribed, was dredged in the Strait of 
Magellan and at Port Otway. 
46. /EGLEA LJEVIS, Lat. 
Specimens of this curious Crustacean, which had been collected in a freshwater stream 
in the neighbourhood of Valparaiso, were given to me by an officer of H. M. S. * Topaze,’ 
then on the Chilian station. 
MACRURA.
