process has three short, strong bristles distally. Basale: The backward pointing process has 

 four distal bristles, three or four triaena bristles and two dwarf bristles. The triaena bristles 

 have from two to five pairs of secondary spines beneath the distal pair of spines. The glands 

 issue on an almost entirely reduced peg. At about the middle of the dorsal side of this joint 

 there is a single bristle, which is about half as long as the dorsal side of this joint; this bristle 

 has short, fine hairs distally. On the outside of this joint there are also groups of short, stiff 

 hairs dorsally, some of which, at least, are rather coarse. The e x o p o d i t e is, if its two 

 distal bristles are included, somewhat more than two thirds of the length of the anterior side 

 of the first endopodite joint. Endopodite: First joint: The shortest of the three ventral 

 bristles has only short secondary bristles. The longest of these bristles is armed with about 

 nine short secondary bristles proximally of the long secondary bristles; the next longest of these 

 bristles has no such short proximal secondary bristles. This joint has no spines antero-distally. 

 The second joint has one proximal bristle, which is about a third of the length of the main bristle a. 

 Proximally of this proximal bristle there is a group of short, fine hairs. Between the main bristles 

 b and c there is no long, narrow bristle with short hairs. The medial cleaning bristles are rather 

 numerous, varying somewhat in number (fig. 13); three specimens that were investigated 



showed the following conditions:

The end claw is somewhat longer relatively than in A. Grimaldi, about as long as or 

 slightly longer than the anterior side of the first endopotlite joint; it is smooth. 



Maxilla (fig. 14): — Protopodite: The distal endite is armed with three 

 subequal bristles. The dorso-proximal bristle is relatively short. The basale has one ventral 

 bristle of moderate length and a series of five subequal dorso-distal bristles, jwhich are in tnost 

 cases somewhat shorter than the ventral bristle. The short ventero-distal bristle is developed.
