'i'his example difters fVoni the type in certain characters, 

 which, in the absence of more material, can hardly be regarded 

 as of specific importance. For example, the intercarinal 

 spaces of the tail are a little less granular and the carapace 

 and terga a little more so than in the tyi)ical female of 

 Oervai.^ti, Poc. Again, the vesicle is very much nanower 

 than the Hfth caudal segment, whereas in Gervaisii it i."? 

 nearly as wide. These are characters, however, which 

 a|)pear to be subject to variation with age, for small examples 

 of Herhslii taken in Demerara by ]\Ir. \W L. Sclater are far 

 more granular than adults captured by the same collector in 

 the same locality, and they have the vesicle noticeably 

 narrower. Consccjuently the distinctive features of this 

 Gurupa s|)ecimen may be provisionally attributed to imma- 

 turity. The di.<eovery of the specimen is, however, of great 

 interest, inasnmch as no locality was previously known for 

 the species.
