No. 19. — Preliminary Descriptions of two New Forms of Peripatus 



from Haiti. 1 



By Charles T. Brues. 



The present brief communication includes preliminary descriptions 

 of one new species and one new subspecies of Peripatus which were 

 obtained by Mr. W. M. Mann on the island of Haiti during a recent 

 collecting trip made by him into the Republic of Haiti which occupies 

 the western part of this West Indian island. He secured two speci- 

 mens of this interesting genus, each representing a different form. 

 One, which is described as a new species, is closely related to a species 

 from the Caribbean coast of South America, while the second appears 

 sufficiently close to Peripatus dominicae to rank as a subspecies of the 

 latter. 



It is impossible to make a complete study of these specimens at the 

 present time but the extreme interest of any information relating to 

 the geographical distribution of these animals, particularly in Haiti, 

 has made an early account of the present material appear advisable.

9 . Resembles Peripatus dominicae var. juanensis Bouvier quite 

 closely, but the large primary papillae are more approximate and 

 although frequently separated from one another by smaller papillae, 

 quite generally appear in pairs with a single small papilla interpolated 

 between the pairs of large ones. Many of the smaller papillae also 

 tend to approach the sides rather than the ridge of the tegumentary 

 folds. 



Form and dimensions. The type measures 45 mm. in length and is 

 rather slender for members of this group. Thirty-one pairs of legs; 

 the nephridial tubercles of the fifth pairs of legs not attached to the
