H1ab.—The worms were very common in the soil about the roots of banana plants 
in Fiji, July, 1891. The males were especially common, Only one female was seen, 
so that I am not perfectly certain that the male and female here described together 
really belong to one and the same species. 

5. D, granuliferus, n.sp. 4-38-25 137mm. The six lips are very distinct 
and each bears the usual two papille. The anterior part of the cesophagus is one- 
fourth as wide as the corresponding part of the neck and is surrounded in front of 
i) 
the nerve-ring by three elongated granular bodies which become conspicuous when 
the worm is immersed in weak osmic acid; behind the nerve-ring the cesophagus 
gradually expands until it becomes, in the posterior half, two-thirds as wide as the neck. 
The tessellated intestine is about two-thirds as wide as the body and is composed 
of cells of such a size that about twelve side by side make up the circumference. 
The narrow rectum is somewhat less than twice as long as the anal body-diameter, 
being about equal in length to the tail. The pre-rectal portion of the intestine 1s 
one and one-half times longer than the rectum. The lateral fields are one-third as 
wide as the body. The tail is pointed and decreases more rapidly in the anterior half 
than in the posterior half. The reflexed portions of the ovaries reach half-way back 
to the vulva. The eggs are a trifle longer than the body is wide and a little more 
than one-third as wide as long. Figured on Pl. x1.

- 52mm. The neck is cylindroid to near the 
nerve-ring ; thence it is convex-conoid to the expanded lip-region. There are Six 
distinct lips, and six papillee, also distinct. The rather slender spear slides na 
pharyngeal ring and can be clearly traced back a distance three times as great as the 
width of the head. The anterior third of the cesophagus is narrow ;—it widens rather 
suddenly, so that the posterior two-thirds are three-fifths as wide as the corresponding 
part of the neck. The thin-walled tessellated intestine is three-fourths as wide as 
the body and is composed of cells of such a size that about sixteen are required to 
build up a circumference. The rectum is as long as the anal body-diameter ; the 
pre-rectum is five times as long as the rectum. The lateral fields are at the neck 
one-eighth, and at the tail one-fourth, as wide as the body. The conoid-hemispherical 
tail seems to have a terminal pore and to contain a considerable number of small 
glands. The depressed vulva leads into a vagina one-half as long as the body is 
wide. The thick-shelled eggs are more or less ellipsoidal ; they are three-fifths as. 
wide as the body and twice as long as wide. The uteri seem to contain but one egg 
at a time, and this is probably deposited before segmentation begins. The ovaries 
reach two thirds to three-fourths the distance back to the vulva. Male unknown.
