except the extreme distal eiid, which is swollen and rounded, and the 

 cloacal eud is terraino-ventral ; the anterior portion of the body is as 

 in the male. 



Color. (I give the color of the two specimens as seen in the 

 concentrated glycerine in which they were placed ; the worms became 

 darker after they were transposed to alcohol.) In the male, the tip 

 of the head is white; the body is a deep yellowish-brown anteriorly 

 which becomes darker distally, and at the posterior end of the body 

 (for the distance of half an inch) chaiiges into a deep reddish color. 

 In the female the tip of the head is white, while the rest of the body 

 is uniformly deep olive brown.

This appears to be a well-marked species without any close re- 

 semblance to the forms described by Kömer (1896, in: Abh. 

 Senckenberg. Ges. Frankfurt a. M., V. 23) from Borneo; it is 

 especially characterized by the occurrence of pairs of tubercles on the 

 cuticle, and by the shortness of their hairs. 



The two type specimens are in the collection of the Wistar 

 Museum of Anatomy, Philadelphia. 



2. Chordodes albiharhattvs n, sp, 



One male, Leidy collection no. 5218, in the possession of the 

 Biological School of the üniversity of Pennsylvania; collected by 

 Dr. Nassau at the Ogove River, Africa. The specific name proposed 

 is compounded of the two adjectives albus and barbatus, and has 

 reference to the white tufts of hairs seen on the cuticle with low 

 powers of the microscope. 



Cuticle. In Cauada baisam on surface views and on sections, 

 four kinds of tubercles may be distinguished: 1) The largest, which 

 always occur in pairs, have a more or less prismatic form (oval on 

 surface view), are but little longer than wide, and apically are obtusely 

 rounded. The distal end of each tubercle is characterized by its 

 hyaline, white appearance, while the remaining portion is darker and 

 stains deeply with eosin ; in none of the other kinds of tubercles is 

 such a structurally difi'erentiated portion of substance to be seen. 

 The proximal portion of the tubercle cousists of a peripheral, darker 

 Zone, and an axial, less deeply-staining portion, so that viewed from 

 the surface these tubercles appear like dark rings. The hyaline,
