miles from the proper Indian Megascolex region. There can be no 

 doubt that while the majority of species of Megascolex have arisen 

 from Notoscolex elsewhere, this species has had an independent 

 origin from a local species of Notoscolex in Assam. 1 



Some other Species of Interest. 



A new Drawida and a new Perionyx are also to be recorded 

 from Assam, and a new Eudichogaster from Bombay. 



It has been interesting to rediscover Eutyphoeus orientalis 

 (Bedd.) with its peculiar penial setae, and Octochaetus beatrix 

 Bedd., in which I have found small penial setae, previously over- 

 looked. 



Both the new species of Lumbricinae illustrate the fact, 

 brought out by Michaelsen (4), that the subgenera of Helodrilus 

 may run into each other, and have no sharp limits. Thus one of 

 the species, which I assign to the subgenus Allolobophora agrees 

 with Bimastus in having no spermathecae ; while the other, 

 which I place in Dendrobaena , agrees with Allolobophora in the 

 characters of the seminal vesicles. 



Family MONIUGASTRIDAE. 



Genus Drawida Mich. 



Drawida nepalensis Mich. 



Dehra Dun, compound of the Forest Research Institute (serial No. 1 1 1 

 of 27 - viii - i92i). 



Dorsal pores are usually absent in the genus Drawida, but I 

 have previously noted (10) that in this species vestiges are present, 

 in the form of gaps in the muscular layers of the body-wall. 

 These vestiges were very obvious in the present specimens, though 

 there were no actual perforations. They occurred from furrow 

 4/5 onwards. 



Drawida rosea, sp. nov. 



Cherrapunji, Assam ; under stones and in muddy pools around Dak 

 Bungalow. S. L. Hora. 28x1921. A single specimen. 



External Characters : — Length 102 mm. Maximum diameter 

 3 mm. Segments 149. Colour grey, but with a faint pinkish 

 tinge dorsally. 



Prostomium prolobous. 



Dorsal pores absent, but vestiges are visible in the middle of 

 the body. 



. Nephridiopores in the line of the lateral setae. 



The setae are closely paired ; aa— 4/5 be ; dd=^/y of the 

 circumference. The setae begin on segment ii. 



The clitellum embraces segments x-xiii, but xiv and perhaps 

 ix are slightly altered.
