touch upon a few essential points of importance in further characterizing this species 
from its other American allies. The species is nearest related to Sp. Benhami and its 
subspecies. The main points of difference and similarity may be found in the com- 
parative table of the species of Sparganophilus. Sp. Benhami is a much more slender 
form than Sp. Fiseni, especially as regards the body posterior to clitellum. The ven- 
tral side of the genital regions in the two species differ. Thus in Sp. Benhami the 
ventral depressed area between the tubercula pubertatis and the oviducal pores is 
circular or oval, while in Sp. Hiseni it is contracted in the middle, the shape of a sand 
time-glass. The presence of a small parietal gland in somite ii in Sp. Hiseni 
distinguishes this species from all others known so far. This gland is paired, extends 
considerably into the ccelomic cavity, is racemose and opens to the exterior in front 
sete 1 and 2, and projects its free apex back through septum into iv. Another 
character is the small size of the septal glands in yi, the corresponding pair in 
Sp. Benhami being larger.
