as to whether it should be placed in the typical form or in the sub-sp. harhadensis ( =Peri- 

 chœta harhadensis , BEDD., =P. pallida ,MlCH.'LfS'N . , =P. amazonica, ROSA, =P.. Sfxwdi- 

 jacobi, BEDD.). In the generally more robust typical form with stronger setae in the 

 anterior part of the body the papillae near the male pores are always united at each 

 side, occupying an oblong oval area medial from the male pores and mostly somewhat 

 oblique. In the sub-sp. harhadensis the papillae near the male pores are scattered, 

 partly very near the male pores, partly near the median ventral line. I therefore 

 think it is best to separate the two forms at least as varieties of a very variable 

 species. A more careful study of these forms later may settle this question 

 definitely. 



In the present specimens from Lahore, which doubtless all belong to the sub-sp. 

 harhadensis, the papillae near the male pores are very variable, in some specimens 

 in great numbers, partly in pairs near the ventral median line at the anterior part 

 of segment i8 ; often pairs of papillae are seen at the hinder part of segment 17, 

 and the anterior part of segment 19 in the lines of the male pores. These papillae are 

 completely separated from those in the immediate vicinity of the male pores. In 

 most specimens papillae are also seen in the region of the spermathecal pores, two 

 pairs on the anterior part of segments 6 and 7 somewhat medial from the lines of 

 the spermathecal pores. In all the specimens examined I found only two pairs of 

 spermathecae at the intersegmental furrows 5-6 and 6-7. 



PHERETIMA VIOI^ACEA (BEDDARD). 



Examined fourteen specimens of this interesting little Pheretima, which enables 

 me to complete the description given by BEDDARD. 



External Characters^. — Dimensions: Most of my specimens are larger than 

 BEDDARD's type specimen. Their length varies from 50 to 80 mm. 



The head shows constantly a singular shape. It is tanylobous, the prostomium 

 being continued backwards as far as the furrow between segments i and 2. The hinder 

 part of the prostomium is not sharply set off, and its lateral borders converge back- 

 wards, almost meeting at the hinder end. The ist segment or buccal ring has a 

 deep ventral median incision almost completely dividing the ring. 



The clitellum extends from the intersegmental furrow 13-14 to about as far 

 as the zone of setae of the i6th segment, leaving the hinder part of this segment free. 



The pair of papillae in the intersegmental furrow 18-19 is not always very 

 distinct, but seems to be present in all the specimens, being marked internally 

 by glandular cushions even if not distinctly visible externally. A deep ventral 

 median depression extends over about segments 16 to 20. In all save two of my 

 specimens a pair of very small, slightly glandular depressions is present in the inter- 

 segmental furrow 9-10, ventro-lateral in position and somewhat resembling a needle 

 puncture. I could not find any special organs or free glands connected with these 

 depressions. 



Internal Anatomy. — The intestine is provided in the 26th (?) segment with 

 a pair of broad and very short lateral caeca which seem^to be rudimentary. They are
