672 DR. A. G. BOURNE ON INDIAN EARTHWORMS. [Dec. 21. 
between them than between a ventral row and the lateral row of the 
same side. 
It is a small weak-looking worm. 
I found specimens at Ootacamund and at Naduvatam. 
MoNILIGASTER SAPPHIRINAOIDES, Sp. N. 
This worm presents a well-marked clitellum extending over somites 
X., Xl., Xli., and xiii. 
The gizzard occupies somites xvii.—xxi. 
This is a very strong active worm, rather larger than a big English 
Lumbricus agricola, and presents most exquisite iridescent colours, 
among which a metallic bluish-green is the most marked. 
I found it in immense numbers in some very wet black mud 
under turf near the Pykarah Waterfalls, at, I believe, an elevation 
of about 6000 feet. When placed in spirit it becomes olive-green 
in colour, while the clitellum becomes almost pinkish. 
MoNILIGASTER ROBUSTUS, Sp. Ne 
The gizzard occupies somites x1.—xv. 
This worm is easily recognized by its very pointed posterior 
extremity, just the anal somites being bright pink, while the rest of 
the worm is dull in colour. In other respects it resembles M. sap- 
phirinaoides. 
I found a few specimens only, crawling across a path on a drench- 
ing day, on top of one of the hills at Ootacamund. 
MoNILIGASTER PAPILLATUS, Sp. 0. 
This species is characterized by long tubular papillee in connection 
with the pores between somites x. and xi. 
The gizzard occupies somites xvi.—xx. 
I found this at Ootacamund and Coonoor. 
This is a much longer worm than any of the other species, with the 
exception of M. grandis. 
MoNILIGASTER RUBER, Sp. Nn. 
The gizzard seemed to occupy only somites xiii. and xiv. In 
somites x., xi., and xii. there were soft-walled swellings of the intes- 
tine looking like gizzard, only not muscular. The worm had a thin 
body-wall, and the organs showing through give it a blood-red 
appearance. It is a small worm about 100 millim. long. 
I obtained only a single specimen from Salem. 
MoNILIGASTER MINUTUS, Sp. n. 
The gizzard occupies somites xii., xili., and xiv. 
This is a small worm resembling Perionyx saltans in appearance, 
but not very active. The ovaries, or at any rate sacs containing ripe 
ova, occupy somites xii.—xv. at least. 
I found numerous specimens in wet ground at Salem. 
When 1 have determined more accurately the structure of the 
generative organs in this genus, this species will probably prove an 
interesting one.
