THE SPECIES OF AEGLA — SCHMITT 483 



accurate portrayal of the salient characters in nearly every particular, 

 including the sharply spined epimeral angle and the stout meral spines 

 of the cheliped, as well as the row of spines on the carpus above the 

 spined inner margin of this joint; only the middorsal row of scabrosi- 

 ties of the carpus are a little too prominent in his figure. 



A. denticulata is virtually in a class or group apart from all other 

 Aeglas; only A. prado, which I discovered and described before I 

 came upon this denticulata material, at all approaches it, and then 

 only in the keeling of its carapace in certain specimens, and also, 

 to a slight degree, in the spining of the palmar crest and the inner 

 margin of the carpus of the chelipeds. 



Distribution. — As Nicolet says, "found in the republic" of Chile, 

 but, so far as I know, the only specimens that have been seen since 

 his time, 1849, are those from Osorno redescribed here. 



AEGLA PAPUDO, new species 



FiGUBE 54; Plate 27, C 



Description. — A species of moderate size, attaining a length of 

 carapace and rostrum of at least 26 mm. 



Carapace very convex, perhaps more so than any other species of 

 Aegia, especially across the gastric region. Kostrum more or less 

 elongate-triangular yet along the middle of its length, in small part 

 at least, with its lateral margins approximately subparallel; basally 

 the rostrum is transversely fairly flattened and depressed either side 

 of rostral carina ; the rostrum has a strong downward trend, but its 

 distal portion is markedly recurved; rostrum extends at least the 

 length of the cornea or a little more in front of the eyestalk; either 

 side of its median carina the rostrum is a little troughed or excavate ; 

 the carina extends forward only from one-half to not more than 

 two-thirds the length of the free portion of the rostrum; beyond the 

 anterior end of the carina the dorsal surface of the rostrum is gener- 

 ally for the most part gently concave from side to side and usually, 

 but not always, without any but a slight trace of the carina or any 

 corneous scaling in line with that on the carina itself; the corneous 

 scales on the carina are very dark brown, thick, and almost beadlike ; 

 the carina runs posteriorly almost to the anterior margin of the pro- 

 togastric lobes, its dorsal beading, however, extending back only to 

 about halfway between the epigastric prominences and the anterior 

 margins of the protogastric lobes ; the carinal beading forms a single, 

 virtually straight, at times slightly wavy row of scales. 



The epigastric prominences are subacute-tubercular and topped 

 with 2 to 6 beadlike scales like those on the rostral carina ; one or 

 two similar beads likewise mark the apices of the acute-angled an-
