by a tube one-fourth as wide as the part of the neck it traverses; ventral excretory 
pore opposite the nerve-ring ; intestine thick-walled, with a distinct chitinous lining ; 
rectum as long as the anal body-diameter; tail conical; vulva elevated; female sexual 
organs probably double and symmetrical.

2. C. infestans, n.sp. Female unknown. 5—39-g¢7a5—3 #m. The cuticle is 
not striated and is destitute of hairs. The conoid neck ends in a small truncate head 
with a slightly expanded lip-region. Neither setz nor papilla were seen on the 
head. The anterior half of the pharynx is triquetrous and about one-fourth as 
wide as the head, while the posterior half is much narrower. The cylindrical anterior 
half of the cesophagus is about one-third as wide as the corresponding part of the 
neck ; the posterior half is at first very slender, less than half as wide as in the 
anterior part, but expands finally to form an ellipsoidal bulb half as wide as the base 
of the neck. There are no eyes. The intestine is three-fourths as wide as the body. 
The tail is conoid. The length of the two equal elongated arcuate acute spicula is 
equal to that of the anal body-diameter ; the proximz are cephalated by constriction. 
The two accessory pieces are more than half as long as the spicula and are arranged 
parallel to them. At least four pairs of submedian papillae occur on the posterior 
part of the male: 1, a pair as far in front of the spicula as the heads of the latter are 
in front of the anus; 2, a pair opposite the anus; 3, a pair at the beginning of the 
central third of the tail ; 4, a pair at the end of the second third of the tail, ze., as 
far behind the anus as the pre-anal pair is in front of it. The blind end of the single 
reflexed testicle lies as far behind the cardia as the latter is behind the lips ; from 
thence it passes forward half-way to the cardia, then turns backward. The ejacula- 
tory duct appears to be twice as long as the tail. Sketches of this worm occur on

in Dr. de Man’s genus 4x/o/aimus for reasons that will be plain on comparing the 
Fiji worm with that of Holland. The cuticle appeared to me entirely naked and 
destitute of strie. The sub-cylindroid neck terminates in a convex-conoid head, 
whose truncate apex bears three (?) obscure lips without conspicuous papillz. There 
are no eyes, and no lateral organs were seen. The cylindroid pharynx is on the
