NO. 14 MILLIPEDS OF WEST INDIES AND GUIANA LOOMIS 65 



INODESMUS PEDUNCULARIS, n. sp. 



Plate 4, figs. 5 and 6 



Over a score of female specimens were found on the under side 

 of a log near Paramaribo, Dutch Guiana, March i, 1932. 



Description. — Length 7 mm, width .6 mm. 



Living animals white and remaining so in alcohol. 



Head exposed from above ; densely beset with short hairs to the 

 clypeal region ; vertex with a median furrow ; front crossed by a deep 

 transverse furrow just below the antennal sockets ; clypeal region 

 elevated, smooth, with four long setae near base and about eight others 

 along the margin ; antennae separated by a distance equal to the di- 

 ameter of one of the sockets. 



First segment narrower than the head or ensuing segments, oval 

 in shape. 



Ensuing segments without any definite projecting lateral carinae, 

 these being indicated by rather prominent shoulders on the anterior 

 segments which become less obvious toward the back end of the body. 

 Dorsal surface of the segments finely granular and beset with long, 

 erect, but flexuous hairs. 



Second segment extending farther ventrad than any other segment ; 

 the sides in front produced forward and covering the posterior lateral 

 margin of segment i . There is a definitely produced, rounded promi- 

 nence at the posterior corner, opposite the lateral limit of segment 3. 



Segment 5 with a definitely pedunculate pore on each side close to 

 the anterior margin of the subsegment. On the other segments the 

 pores are on smaller peduncles and are near the middle of the segments. 



Last segment with a deflexed mucro surpassing the valves except 

 when they are open. 



Other characters given by Silvestri in the generic description of 

 Lasiodesmus are exhibited by this animal. 



Type.— U.S. ^M. no. mo. 



After comparing the present species, from a generic standpoint, 

 with Silvestri's description of Lasiodesmus and with the brief char- 

 acterization of Inodesmiis Cook," there appears to be no reason for 

 maintaining Silvestri's genus. Chamberlin's assumption that Lasiodes- 

 mus belongs to the Strongylosomidae '" is erroneous. The question 

 of the distinctness of Inodesmus jamaiccusis Cook and /. caraibicus 

 (Silvestri) cannot be decided until comparison is made of the types 

 or of specimens undoubtedly similar to the types.
