Genus MACROPERIPATUS A. H. Clark 



MACROPERIPATUS INSULARIS, new species 



Locality. — Between Jacmel and Tronin, Haiti; Dr. O. F. Cook, 

 April 11, 1926. One female, the type (U. S. N. M. no. 1275). 



Description. — The type and only specimen is a female 55 mm long, 

 4.5 mm broad, and 2 mm high, with 30 pairs of legs. 



The dorsal plications are very regular, all of the same width. 

 The principal papillae are subequal, on squarish or oblong bases 

 that rise into a broad and very low cone surmounted by a high and 

 prominent truncated cone or slightly tapering cylinder. The large 

 papillae are commonly separated by one or two less developed pa- 

 pillae that often lack the terminal cone, rising from narrow bases. 

 On the dorsal surface between the legs of each pair there are two 

 intercalated partial plications, giving rise to a slight irregularity. 

 The two plications over the middle of each leg tend to divide, more 

 or less irregularly, just above the leg, there forming three or four 

 short, irregular, incomplete plications. The midline of the dorsal 

 surface does not differ from the remainder, except that here the 

 bases of the papillae are narrower. 



The legs of the fourth and fifth pairs bear four arcs with frag- 

 ments of a fifth. The urinary tubercle rather strongly depresses the 

 fourth arc, and appears to be independent of the third. 



The salivary glands extend to the vicinity of the genital orifice. 



The color in alcohol is uniform yellow-brown, lighter beneath. 

 The color in life was not recorded. 



A-fJinities. — This new species appears to be rather closely related 

 to Macroperipatus perrieri (Bouvier) from Veracruz, Mexico. The 

 type and only known female of that species is 51 mm long and has 

 32 pairs of legs.
