antenna, X27J. 



Cymodoce multidens, sp. nov. 



This species is very close to Cymodoce tuberculosa Stebbing, « but differs in having the 

 anterior margin of the head produced in one small median point instead of two; in 

 having the first article of the first pair of antenna? furnished with a row of nine teeth 

 instead of five and an additional tooth just anterior to the row, situated at the proximal 

 extremity of the joint; in having one tooth on the second article of the first antennae; 

 in not having the first abdominal segment produced backward in "two prominent 

 posterior projections," & but in having a small tubercle on either side with another 

 just above it. 



Further comparisons of the two species are impossible, because the descriptions of 

 Stebbing, Whitelegge, and Baker differ. Stebbing says the anterior margin of the 



a Annals and Magazine of Natural History, ser. 4, vol. xu, 1873, p. 95, pi. Ill, fig. 1.
