touch u|)<ni ;i few essen(i:il points of importance in furtlier characterizing this species 

 from its oilur American allies. The species is nearest related to Sji. Htuhnial and its 

 subspecies. The main points of difTerence and similarity may he found in the com- 

 parative table of the species of Sparganophilus. Sp. Benhn7ni is a much more slender 

 form than Sp. Ekeni, especially as regards the body posterior to clitelhim. The ven- 

 tral side of the genital regions in the two species difler. Thus in Sp. BcnJiaini the 

 ventral dejiresscd area between the tnbercula pubertatis and the ovidiical pores is 

 circnlar or oval, while in Sp. Emud it is contracted in the middle, the shape of a sand 

 time-glass. The presence of a small parietal gland in sotnite iii in Sp. Eiseni 

 distinguishes this species from all others known so far. This gland is paired, extends 

 considerably into the coHomic cavity, is racemose and opens to the exterior in front 

 setse 1 and 2, and projects its free apex back through septum into iv. Another 

 character is the small si/e of the septal glands in vi, the corresponding pair iti 

 Sp. Benhami being larger.
