\V. 81/1. Pliagu, near Simla, alt. 9000 ft. ; in very wet earth at edge of 

 spring. ii-v-igi6. N. Annandale and S. W. Kemp. Four speci- 

 mens. 



The specimens from Phagu are noted as having been, when 

 captured, deep purple above with strong green iridescence, and 

 much paler below. 



There was really no gizzard ; in segment vi the oesophagus 

 was rather swollen, but the walls when cut into were not thickened. 

 There was no widening of the oesophagus in segment xiii. 



There were no diverticula on the spermathecae (examined 

 microscopically also) ; this was not apparently due to the speci- 

 mens being in an early stage of sexual maturity, since all the 

 other parts of the genital system are well developed ; the ovaries 

 are large, and the seminal vesicles of segment xii reach backwards 

 as far as septum 13/14. I have previously found the diverticula 

 absent in a specimen from Dibrugarh, N. E. Assam (17). 



Specimens which were immature, but referable with more or less 

 of probability to this species, were obtained from the following 

 localities : — 



Kasauli, W. Himalayas. Baini Prashad. 3i-vii-i9i6. 

 Talewadi, near Castle Rock, N. Kanara District, Bombay Pres. Oct. 1916. 

 S. W. Kemp. 



Pcrionyx pallidus, sp. nov. 

 (PI. xvi, figs. 5, 6). 



W. 89/1. Kalimpong, Darjiling Dist., E. Himalayas ; alt. 600-4500 ft. 

 24-iv to 10-V-1915. F. H. Gravel)-. Several specimens, one mature. 



External characters. — Length 80 mm. ; thickness 3*25 mm. 

 Colour pale, with purplish tinge dorsally at anterior end, and pur- 

 ple median stripe throughout the body. Body slightly depressed 

 in the anterior portion. The mature specimen was regenerating 

 the hinder end ; another of the same size showed 118 segments. 



Prostomium epilobous ^ ; the sides of the tongue parallel. 



Dorsal pores from furrow 4/5. 



The setae are in rings which are quite closed ventrally, and 

 almost closed dorsally. The middorsal interval varies slightly ; in 

 the anterior part of the body zz averages i^ yz, further back 

 about i^yz. The setae are set closer together ventrally than later- 

 ally or dorsally ; there is no difference in the size of the setae in 

 different segments. The following numbers were counted: — 53/v, 

 72/ix, 52/xi, 64/xii, 52/xix, and in the middle of the body 70. 



The clitellum extends over segments xiii-xvi = 4 ; the body is 

 slightly swollen here, and buff in colour ; setae are present as 

 elsewhere. 



In segment xviii the midventral region is slightly depressed, 

 and running across it in the position of the setal line is a groove, 

 sharply cut and narrow, though rather wider and deeper at the 

 position of the male pores ; these are small cracks, one-tenth of the 

 circumference apart, or with an interval of about seven intersetal
