This species is referred to in the introduction. 
Pheretima lignicola, Stephenson. 
Malabar Hill, Bombay; 30-x-1914 (W. S. Millard). Five specimens, soft and in bad condition. 
This species was previously described by me (21) from the Abor country. ‘The 
correspondence between the present specimens and the previous description is close; 
since however I had then only a single specimen at my disposal, which was necessarily 
handled with care, I subjoin here a few additional notes. 
External characters.—Length 165 mm., diameter 6! mm.; colour a dark brownish 
purple dorsally, but pure brown after stripping off the iridescent cuticle; brown 
ventrally; clitellum lighter brown. Segments 130. 
Male apertures large, pit-like, on xviii, distant from each other ? of the circum- 
ference. The margins of the pits are whitish, swollen and puckered, and much less 
well defined on the inner side. 
Female aperture single, small, in a transversely oval, dark, moderately shallow 
but conspicuous pit, on xiv about the middle of its length. 
The small spermathecal apertures, surrounded by whitish lips, are approximately 
in line with f. 
The numbers of setae counted were 33/v, 45/ix, 56/xii, 64/xix. 
Internal anatomy.—Septum 4/5 is deänitely present, and slightly thickened. 
Septum Io/II is attached to the parietes at the level of the setae of xi; II/I2, 12/13 
and 13/14 are also all attached behind the level of the corresponding intersegmental 
grooves. | 
The intestine here begins in xvi, and the diverticula originate in xxvii; these 
latter are simple, finger-shaped, and extend forwards through xxvi and xxv. 
I am able to give a better account of the anterior male organs than in the first 
description. The testes and funnels are enclosed in sacs, those of segment x being 
small; funnels, but not testes, were distinguished within them; they are situated on 
the anterior face of septum 10/11, and probably communicate with each other across 
the middle line below the alimentary canal. The sacs in segment xi were larger, 
separated by the alimentary canal between them, and contained both testes and fun- 
nels, as well as the anterior seminal vesicles, which depend backwards from septum
