posterior end of sternite on each side and in relation to caudal 
gland a ventrally projecting small setose lobe which is 
farther forward on the joint and apparently less strongly 
developed than in species of Polygonarea. 
Anal pores conspicuous. 
Anal legs ending in well developed claws. 
Number of pairs of legs 41 in all three types. 
Length, 15 mm. 
Locality. — Panama: Barro Colorado Id., July 25 and 26 
and Aug. 7, 1938, one specimen on each date. 
Nabocodes, gen. nov. 
Clypeal area single, far forward. Lateral pieces of lab- 
rum relatively short and broad, pectinate, widely separated 
by the median piece. Telopodite of first maxillae biarticu- 
late, without external lappets. Coxae of second maxillae 
only narrowly and weakly joined at middle; the pleuro- 
sternal line long, running ectad of the mesally open pore. 
Prehensors long, exposed from above; claw and femoral 
joints armed within; no chitinous lines developed. Ventral 
plate absent. Last dorsal plate normally broad. Last ven- 
tral plate broad. Coxal pores small, typically few along 
and beneath ventral plate. Anal pores present. Anal legs 
without claw. 
Genotype. — Nabocodes mimellus Chamberlin, sp. n. 
This genus differs from the African Brachygonarea in 
lacking lappets on the first maxillae and in having the 
anal legs clawless. It differs from Barrophilus in lacking 
the processes from meso-anterior corners of the coxae of the 
second maxillae, in lacking claws on the anal legs, and in the 
character of the coxal pores. 
Nabocodes mimellus Chamberlin, sp. nov. 
Pale yellow, with head and prehensors of slight chestnut 
cast. 
The head of shape and proportions similar to that of the 
preceding species, but with anterior corners more obliquely 
rounded. 
Claws of prehensors when closed attaining distal end of
