 phridia open in IV, end in V, narrow, slightly and irregularly branched. 

 Brain anteriorly and posteriorly convex, ovoid. Dorsal vessel rises in 

 XVI. Intestine narrow and tubular, changing into sacculated intestine 

 in XIV. Spermathecae with a row of six or seven bladder-like diver- 

 ticles around the ampulla ; two small accessory glands at the base of 

 the muscular duct. Sperm-ducts long, narrow, with a small penial

DETAILED DESCRIPTION. 



SpermatheccE. — The diverticles are large and with irregular out- 

 lines. Generally one or two diverticles are larger than the others. 

 The duct is even, slightly bent, and somewhat longer than the ampulla. 

 The latter opens into the intestine. The two small glands at the base 

 of the duct are about as wide as the duct. 



Penial bulb. — There is only one kind of gland composing the 

 penial bulb. The sperm-ducts enter the bulb near the base, splitting 

 the bulb into two unequal parts.
