TRICOMA AND OTHER NEW NEMATODE GENERA, 



of an annelid. This appearance is so deceptive that one of 

 the most renowned helminthologists in Europe pronounced the 

 only specimen yet seen to be the larva of an annelid worm. 

 It was therefore with some hesitation that I included the 

 specimen in my Nematode collection. However, after careful 

 examination I am convinced that the worm is a representative 

 of an hitherto unknown Nematode genus. The only specimen in 

 my possession was probably either lost or destroyed ; not, how- 

 ever, until after the accompanying reliable drawings of the two 

 extremities had been made with the aid of the camera lucida. 



T. CINCTA, n.sp. The length, which I give from memory, was 

 somewhere between one and two millimetres, and the width 

 probably about three to four hundredths as great. The coarsely 

 striated cuticula bore hairs throughout the length of the worm, 

 in cycles of three. The head, surmounting a cylindroid neck,

 which issued from a conoid projection at the base of one of the 

 three lips. The lips projected forward in the form of a cone 

 and were flanked by large cuticular expansions, or cephalic alse. 

 The oesophagus averaged nearly one-third as wide as the neck ; — 

 I remember nothing further concerning its structure. Whether 

 any bulbs existed I cannot say. The tail ended in an unmistakable
