I,aliore ; very common. 



This species is one of the commonest in Lahore, and being 

 always procurable it is used as a type of the Oligochaeta in our 

 Zoological classes.

Pheretima hawayana (Rosa). 



Lahore ; not uncommon. 



I give below a few of the external characters of this species 

 as it occurs at Lahore. 



The setal ring is always broken dorsally, the interval zz being 

 usually equal to zyz or rather more. Ventrally also there is a 

 break, which is rather less than the dorsal ; aa=i^ — 2ab, — rather 

 less in front of the clitellum than behind Setae are as a rule 

 not visible on the clitellum except ventrally on segment xvi ; in 

 one instance a few were seen v'entrally in xiv also. 



In two cases out of live it was noted that there was no 

 marked difference in size between the setae of the anterior and 

 subsequent parts of the body ; in one they were smaller behind 

 the tenth segment ; in one the setae of segments v-vii, and in 

 another of iv^-viii were enlarged. 



The clitellum may or may not include the whole of segment 

 xvi ; in the latter case it is not fully three segments in extent. 



The papillae in the neighbourhood of the male pores are 

 variable ; but all specimens agree in the fact that none are situated 

 external to the apertures. They are mostly arranged in two 

 transverse lines, one near the anterior border of xviii. and another 

 similarly placed in xix; the line in segment xviii may be composed 

 of as many as eight papillae, the one in xix contains fewer. 

 Other papillae ma}'^ occur on the posterior part of xviii, behind 

 the level of the male apertures ; and less frequently on the ante- 

 rior part of xvii. 



Papillae also occur in the neighbourhood of the spermathecal 

 apertures, — either situated behind the apertures, or in the mid- 

 ventral line on segments vii and viii. 



Length of specimens 100 mm., breadth 4 mm. 



The specimens thus agree with the typical form of the species 

 in having stouter setae in the anterior part of the body, and in 

 having a broken setal ring. In the distribution of the genital 

 papillae, and in the extent of the clitellum over three segments, 

 or nearly so, they resemble the subspecies harhadensis. The
