NO. 5 A NEW NEMATODE WEHR 3 



ovejector about 1.35 mm long and averaging about 134 fj. in width, 

 describing one knee-shaped bend a short distance from vulvar open- 

 ing and a second one at the point of its union with uterine vagina. 

 It was impossible to determine the length of the uterine vagina because 

 of the many coils of egg-filled uteri that concealed it. Posterior end 

 of intestine atrophied ; anus not discernible. Tail broadly rounded. 

 Eggs in posterior portions of uteri containing embryos ; those in an- 

 terior portions not embryonated. hZmbryonated eggs 48 to 52 fi long 

 by 32 to 36 /u. wide, with a shell about 8 //, thick. 



Host. — Hispaniolan woodpecker, Chryserpes striatus. 



Location. — Body cavity. 



Locality. — Santa Barbara de Samana, Dominican Republic. 



Type specimens (male and female). — U.S.N.M. Helm. Coll.

D. sen-atospicula may be distinguished from all other species of the 

 genus Diplotriaena, so far as the present writer is able to determine 

 from the published descriptions and figures of those species, by the 

 short spicule which is serrated for its entire length except for the two 

 extremities, and by the size of the long spicule, which is nearly two 

 and one half times as long as the short spicule. This long spicule 

 is exceeded in length by those of only two other species of the genus, 

 namely, D. nochti Hoeppli and Hsii (1929) and D. obtuso-caudata 

 (Rudolphi, 1 819).
