;)() CKAHS OF FAMILY MAIID.K KATHHUN. 



A. INfilne Edwards records tliis species in tlte text as ft^tioida, while 

 ill the deseriptioii of the figure it is designated as rotundntH. The types 

 are from ott' Patagonia and Brazil. 



In characterizing the two specimens at hand, 1 have compared them 

 with specimens of mutica of equal length from South Carolina, and 

 have made the following observations: The width at the branchial re- 

 gions is the sanie, but rotunda is wider at the hepatic regions. The 

 gastric and cardiac regions are a little more swollen in this species. 

 The rostrum is the same length in both species, but in muticd the horns 

 are strongly divergent, while in rotunda the outer margins are subpar- 

 allel. The rostrum is more deHexed ami wider at the base in >o/fn*f/<f 

 and there is a corresponding width underneath across the basal antennal 

 joints. The fingers do not dilfer essentially from those of muti('<(. It 

 is very ju-obable that a large series of specimens of rotnnda would show 

 that the above mentioned characters are not constant, but otier indi- 

 vidual variations as in mntica.

Pelia. sp. 



Much like pacijica. The single male specimen, however, has cheli- 

 l)eds very strongly developed. Manns wide and swollen, fingers 

 arched. The first ambulatory leg is longer than in pacifica, the merus 

 joint nearly reaching the extremity of the rostrum; the i)enult joint is 

 longer and more slender than in pacijica. The rostrum has its horns 

 converging, but is deformed, as the two sides are of uneipnil length.
