REPORT OPON TWO COLLECTIONS OF MY RIO POD A. 173 



Differs from all the known Ceylouese forms in that the coUum 

 extends laterally below the level of the 2nd somite. 



Family, FolyzonidcB. 

 Sijjhonophora hivmherti, sp. n. 



Colour (in alcohol) uniformly ochraceous. 



Body slender, composed of 60 segments. 



Head ovate, about as long as the rostrum which is lightly curved ; 

 antennce about as long as the rostrum. 



Somites lightly convex above, meeting the pleurae at an obtuse 

 angle, and separated from them by a distinct suture, neither tuber- 

 cular nor carinate. (The upper part of some of the somites is higher 

 than the others. But since there is no symmetry in these elevations 

 I shall regard them as abnormalities, until evidence to the contrary 

 is forthcoming.) Anal somite blunt posteriorly. 



The head and upper part of the somites densely and coarsely 

 hairy and granular ; pleurae granular but less hairy ; rostrum smooth. 



Length about 12 mm. 



A single specimen from Punduloya (Mr. Green). 



Only one species of this genus has hitherto been recorded from 

 Ceylon, namely, S. j^ictefi of Humbert, This species is unknown 

 to me, but judging from the figure, it is much stouter in build 

 than the one here described. Moreover, the somites are laterally 

 carinate.
