66 ZOOLOGICAL COLLECTIONS MADE DURING [JaU. 4, 



Epialtus DENTATUS. 



Epialtus dentatus, M.-Edwards, Hist. Nat. Crust, i. p. 345 (1834); 

 Nicolet, in Gay's Hist, de Chile, iii. p. 131 (1849) ; Cunningham, 

 ;. c.p. 491 (1871). 



Inachus mitis, Poppi?, A.rch. f. Naturg. ii. p. 141 (1836); Gay, 

 Hist, de Chile, iii. p. 125 (1849). 



A single small female is in the collection, obtained on the beach 

 in Trinidad Channel. Its occurrence at various widely separated 

 localities on the coast of ChiU is noted by Dr. Cunningham. 



Epialtus marginatus. 



Epialtus marginatus. Bell, Proc. Zool. Soc. p. 173(1835), Trans. 

 Zool. Soc. ii. p. 62, pi. xi. fig. 4, ? , pi. xiii. S (1841); Smith, 

 Trans. Conn. Ac. ii. p. 33 (18G9). 



A female and young male are in the collection, from Tal- 

 cahuano. 



Pugettia, sp. 



A single female example is in the collection, which is distinguished 

 from P. richii and P. gracilis, Dana, its congeners of the American 

 coast, as follows : — The body is somewhat more elongated and convex 

 on the gastric region ; the lateral expansions or lobes of the carapace 

 are but Httle prominent, forming small, subconical, acute teeth ; 

 the spines of the rostrum are slender and but little divergent. The 

 example is a small one ; and being of the female sex it would not 

 be desirable to constitute it the type of a new species. If distinct, 

 as is probably the case, it may be named P. australis. 



It was obtained at a depth of 28 fathoms, on a bottom of black 

 saud, in lat. 36° 47' S., long. 55° 17' W., at the mouth of the Rio 

 de la Plata. 



PiSOIDES EDWARDSI. 



Hyas edwardsii. Bell, Proc. Zool. Soc. p. 171 (1835), Trans. 

 Zool. Soc. ii. p. 49, pi. ix. fig. 5 (1841). 



Pisoides tuberculosus, M.-Edw. & Lucas, in d'Orbigny's Voy. 

 Amer. merid. vi. Crust, p. 11, pi. v. fig. 1 (1843); Nicolet, in 

 Gay's Hist, de Chile, iii. p. 134 (1849) ; A. M.-Edwards, Crust, in 

 Miss. Scientif. Mexique, p. 75, pi. xvi. fig. 5 (1875). 



Pisoides edwardsii, Dana, Cr. in U.S. Expl. Exp. xiii. i, p. 87, 

 pi. i. fig. 2 (1852). 



Two males were collected : — one at Trinidad Channel, at a depth 

 of 30 fathoms, on a sandy bottom ; the other at Port Rosario, at 

 2-30 fathoms, on a bottom of sand and rock. 



This is a very interesting addition to the Museum collection, as 

 both genus and species were hitherto unrepresented in it. It is one 

 of the few Magellan species having a considerable range to the 

 northward, having been obtained from Chili (Valparaiso), the Gala- 

 pagos, and Panama. Its occurrence in the Straits of Magellan is 

 now, I believe, for the first time recorded.
