MONILIGASTER GRANDIS, A. G. B. 363 
the only species in which I have found the gizzard so far back ; 
in Desmogaster the gizzard occupies, according to Rosa, Seg- 
ments XX—XXIX. 
M. pellucida, sp. n. 
Size, 90 mm. long (presents great variations, many speci- 
mens as long as 190 mm., as in the specimen figured), 9°25 mm. 
in circumference. 
Segments, 130, not annulated. 
Pigment absent. 
Setz 0:24 mm. long, dorsal gap 6 mm., lateral gaps 1 mm., 
ventral gap 1:25 mm. Setz absent from Segment 11. 
Nephridiopores in the direction of the outer seta rows. 
Male pores nearer the inner seta rows than the outer. 
Oviduca) pores slightly dorsad of inner seta rows. 
Spermathecopores slightly ventrad of outer seta rows. 
Septa v-vi—vitl-tx thickened. 
Gizzard in four (or five) lobes occupying Segments xv— 
XVIII (XVIIMXXI, XVI—XX, XV—XIX, XIV—XVII, XIV—XVIII, are 
not uncommon variations). 
Sperm-sacs lemon-shaped. 
Prostates, flattened hemispheres. 
Ovaries not enclosed. 
Spermathece lemon-shaped, in one or two specimens oval. 
Copulatory pouches simple, embedded in the body-wall. 
Vascular System.—Supra-intestinal vessel present, con- 
nected anteriorly with the hearts of Segment 1x, which are 
therefore not “dorsal hearts.” 
Habitat.—Ootacamund and Naduvatam, Nilgiris. 
Remarks.—The habit of this worm of contracting its ante- 
rior end into the shape shown in fig. 3 is very characteristic ; 
this is the shape usually found in spirit specimens. The body- 
wall is very transparent. 
M. uniqua, A. G. B., 1886. (Syn. M. papillatus, A. G. B., 
1886.) 
Size, 220 mm. long, 15°6 mm. in circumference. 
Segments, 316, faintly annulated.
