lobe small and narrow, situated basally. 2nd maxillae (fig. 6) 

 slender, terminating distally in two setose plumes. The segments 

 of the mesosome are strongly convex, lateral plates of ist segment 

 angularly produced backward, those of the 2nd, 3rd, and 4th less 

 so, all tuberculated. Pronotum of ist, 2nd and 3rd segments 

 strongly pronounced. Maxillipedes (fig. 7) broad, the inner plate 

 with numerous short simple setae, the outer palp terminates in 

 three teeth consisting of a series of minute spinous processes 

 (fig. 8) ; basally there is a raised portion minutely studded with 

 small setae. Thoracic appendages fringed with numerous spines, 

 2nd appendages having on the apical border of the fifth joint two 

 with obtuse plumose apices (fig. g), Uropods (fig. 10), basal 

 plate large, extending beyond telson, expanded and plate-like 

 laterally ; outer margin subcrenate, fringed with hair-like setae and 

 tuberculated; exopodite on the inner margin, endopodite longer 

 than exopodite and situated at the top of the inner margin of 

 the basal plate, both covered with fine setae and extending 

 slightly beyond the basal plate. Telson obtusely triangular, tuber- 

 culated. 



Colour (in alcohol) a uniform dark brown. Length ly^ mm. 



Habitat. — Anamalai hills, Madras Pres., S. India, 4,000 feet, 

 22-i-i9i2, No. 8612/10 {T. B. Fletcher). 



I have pleasure in associating the name of the Rev. T. R. R. 

 Stebbing, F.R.S., with this interesting species. 



The genus Paraperiscyphis was founded by Stebbing (6) for 

 another S. Indian species P. travancorensis. vStebbing, which is 

 separated from Pcriscyphis, Gerstaecker, by the following charac- 

 ters : " In the second antennae the first joint of the flagellum is 

 not longer than the second; the telsonic segment is very obtusely 

 triangular, not narrowly produced at the apex; the inner branch 

 of the uropods is attached not to a projection of the peduncle's 

 base, but to a notch far down the inner margin, while still further 

 down is attached the outer branch, not especially small, both 

 branches extending beyond the peduncle, and the peduncle itself 

 extending beyond the telsonic segment." 



All the above characters hold good in the species I am here 

 about to describe, excepting the first, viz., the first joint of the 

 flagellum in the antennae is longer than the second^ otherwise there 

 can be no question but that the present species finds its proper 

 place in this genus. 



The foundation of the genus Paraperiscyphis makes it neces- 

 sary to re-consider the diagnostic characters of the genus Pcris- 

 cyphis, Gerstaecker, who described it in 1873 (5). The diagnosis 

 is as follows: — 



" Pcriscyphis, nov. gen." 



(Trib. ArmadiUini.) 



" Antennae 7 articulatae, articulis duobus apicalibus elongatis, 

 gracilibus, ultimo setifero. Caput margine frontali nullo, supra 

 oculos utrinque leviter carinatum. Annulus corporis primus mar-
