98 MONTG OMER Y. 



hairs, such as are so frequently found in the larger papillae of 

 many species of the genus ; no hairs were to be seen on the 

 cuticle on surface view examined in water and in balsam, nor 

 yet on cross-sections examined with the one-twelfth immersion 

 lens of Zeiss. 



(3) Hyaline, club-shaped, delicate processes scattered spar- 

 ingly over the cuticle (Fig. 4). 



Color. - - Black, head rufous-brown. 



Dimensions.- -Length, 425 mm.; greatest diameter, 2 mm. 

 The structure of the genital organs showed this specimen to be 

 sexually mature. 



Comparisons. - - This appears to be a well-marked species. 

 In the arrangement of the papillae it bears some resemblance 

 to C. fcstac Camerano, but differs from the latter in having no 

 fine hairs (" corti e fini prolungamenti trasparenti ") on the sum- 

 mits of the papillae and also in having no large, transparent, 

 recurved hooks on the surface of the cuticle (cf. Camerano, 

 " Monografia dei Gordii," Accad. Real. Set. di Torino, 1897, 

 p. 386, Taf. Ill, Fig. 38). 



It is a pleasure to me to name this species in honor of Prof. 

 Lorenzo Camerano, of Turin, who has given such an able syste- 

 matic monograph of the group.
