is shorter, rounded and blunt, the internal, directed inwards towards 

 its fellow of tlie opposite side, has the form of an upcurled hook ; the 

 posterior piece sends a long slender process down the outer surface 

 of the anterior piece, but ceases at the base of the external process ; 

 the central (protrusible) piece is distally expanded, sub -membranous, 

 and spirally coiled, the membranous portion is divided distally into 

 two laminae, each of which is irregularlj'- excised along its free border, 

 and the posterior is armed with a single elongate style. 



The specimens here identified have been compared with Newport's 

 type of the species, which is preserved in the British (Nat. Hist.) 

 Museum. Newport vaguely gives 'East Indies' as the locality of this 

 species. It is consequently satisfactory to know exactly an area 

 where it does occur. 



Spirostreptus hamifer, Humbert.

 Madras (Mr. Thurston), and Punduloya (Mr. Green). 

 The Madras specimen that I refer to this species differs from 

 the specimen figured and described by Humbert in possessing 66 

 segments, and in having the lateral portions of the coUum posteriorly 

 striate. The caudal process moreover is longer and more hooked 

 than in Humbert's specimen. 



This species was originally obtained from Peradenia in Ceylon ; 

 this is, I believe, the first record of its existence on the mainland. 

 It is of small size, slender build, and may be recognised by its 

 curiously hooked caudal process. 



Spirostreptus caudiculatus, Karsch. 

 Zeits, Gen. Naturwis., (3), vi, pp. 27, 28 (1881). 

 Madras : Mr. Thurston sent one specimen only. Described by 

 Karsch from Ceylon. 



This species is small, measuring about 50 or 55 mm. in length, and 

 being relatively slender. It may easily be recognised by the longi- 

 tudinal parallel ridges that adorn the segments, a form of sculptur- 

 ing in which it closely resembled Spirobolus crebrestriatus of Humbert 

 from Ceylon. But apart from its different generic characters, Sp. 

 (^.audiculatiis may be at once recognized by its pointed and upcurled 

 ^ tail' — a process which is not developed in Sp. crebrestriatus. 



The two specimens from Madras have a median dorsal flavous band.
