capsule’s attachment to the cesophagus and angular in lateral 
view. ‘The dorsal cesophageal gland discharges through a 
tunnel in the mid-dorsal line, and opens unprominently into 
the oral cavity. 
The male has a length of 4:5* and a maximum breadth 
about the equator of 0°275. The dorsal rays are united for 
nearly three-quarters of their length, the ununited portion of 
each ray almost immediately bifurcating into an outer thin 
and an inner stout branch, the latter again dividing. The 
bases of the externo-dorsal rays occupy, not quite symmetri- 
cally, the second quarter of the dorsal ray. ‘lhe lateral rays 
spring from a common base ; the dorso-lateral is the stoutest, 
separated from the medio-lateral by a deep cleft, both rays 
having a dorsal trend; the externo-lateral, separated from 
the medio-lateral by a somewhat shallow cleft, has a slight 
ventral trend ; the ventral rays are apposed, the prebursal 
papillae: are long. The equal and similar spicules measure 
0-275 long, are gently tapering, and have their fine rounded 
tips curved posteriorly ; the accessory piece is 0-09 long. 
The female has a length of 6 and a maximum breadth 
about the equator of 0325. The distance between the 
anterior end and the cervical papillee, nerve-ring, and excre- 
tory pore is 0°375; the distance of the end of the cesophagus 
from the anterior extremity is 0°75. ‘The vulva lies 2°4 from 
the tip of the conical tail; the intra-uterine ova measure 
0-06 by 0°04. 
Crassisoma samoense, sp. n. 
Stoutish, short, bursate nematodes, with the oral aperture 
dorso-subterminal and guarded ventrally by a pair of semi- 
lunes. The oral capsule is nearly globular (the oral cavit 
corresponding to its shape and size) and is provided with a 
pair of large basal subventral teeth, each irregularly quadri- 
Jateral in shape, attached by its ventral border and promi- 
nently pointed at its free angles. The dorsal cesophageal 
gland discharges through a tunnel in the dorsal mid-line and 
opens unprominently into the oral cavity. 
The male has a length of 5:27 and a maximum breadth 
about the vesicula seminalis of 0°29. The dorsal rays are 
united for about seven-eighths of their length ; the free 
portion divides much as does the corresponding ray of 
Globocephalus connorsilii. The externo-dorsal rays. spring 
from the bases of the united dorsal rays; the other rays
