Tegumentary folds complete on the anterior and middle part of 
the body, except that there may be very rarely an incomplete 
fold which bears no relation to the insertion of the legs; posterior 
third or quarter of body with an incomplete fold more or less 
regularly on the flank about halfway between each leg and the 
median line. Anteriorly there is commonly a fusion of two 
ridges above the leg but in such cases one of the adjacent ridges 
bifurcates downwards at this point and the number of ridges is 
not decreased. The primary papillae vary markedly in size, 
frequently but not always there is one or there may be two 
smaller ones between two adjacent large ones. The accessory 
papillae are quite numerous, more so in larger specimens and 
they frequently ascend well on to the ridges often in a pair (one 
anterior and one posterior) between two primary papillae. On 
very large specimens there are occasional groups of three or even 
four accessory papillae in groups between adjacent primary ones 
in addition to a scattering of accessory ones along the edges of 
the fold. In the largest specimens the primary papillae are of 
nearly equal size. Nephridial tubercle on fourth and fifth legs 
lying in a distinct but not deep emargination of the third creeping 
pad, the fourth pad usually but little shorter than the third, 
but much narrower and deeply emarginate next to the tubercle 
which, however, does not divide the pad. The number of legs 
varies from 33 to 30 pairs, 32 in the type and 32, 32, 33, 33, 30 
and 30 in the paratypes. 
cT. The male measures 25-50 mm. in length, with 29 pairs 
of legs. It is essentially similar to the female although one is 
evidently not fully grown as the form and arrangement of the 
papillae resemble those of the smaller females. The larger spe- 
cimen shows three small primary papillae between the larger ones. 
There are in all eight specimens as follows: Barro Colorado 
Island, Canal Zone, Feb. 6, 1924 (T. E. Snyder) (type); Barro 
Colorado Island, Canal Zone, Feb. 26, 1924 (T. E. Snyder); 
Rio Tapia, Panama, Feb. 7, 1924 (T. E. Snyder); two from Las 
Cascadas, Canal Zone, Feb. 12, 1924 (T. E. Snyder); two from 
Fort Sherman, Canal Zone, February 1924 (J. B. Shropshire); 
Rio Chinilla, Canal Zone, Feb. 22, 1924 (T. E. Snyder); Barro
