its distal half abruptl}^ narrower than the proximal. Dollfus de- 

 scribes and figures the peduncle of the uropods as obtusely quad- 

 rangular, which does not at all correspond with the graceful 

 curves of both inner and outer margins in our species. He repre- 

 sents the branches as narrowly cylindrical, and says that the 

 inner equals about half the length of the outer, though his figures 

 no doubt rightly show that the inner is the longer, as in the 

 new species, in which these branches reach about equally far 

 back, the inner carrying two apical setae. The New Zealand 

 species Actaecia opihensis, Chilton, 1901, has uropods very similar 

 to those of our species. 



Between the antennae the head is ventrally carinate. In the 

 first maxillae I could only make out eight apical spines, and the ar- 

 mature of the inner plate was undecipherable in the dried condition. 

 The maxillipeds are very broad as in Periscyphis. The limbs are 

 fringed with numerous spines, most of them pointed, but one on 

 the apical border of the fifth joint is shown in the first gnathopod 

 as having an obtuse plumose apex. 



The larger of the two specimens measured 11 mm. in length, 

 by about 6 mm. in breadth. 



Locality, — Maddathorai, western base of Western Ghats, 

 Travancore. 



The specific name is taken from that of the region whence 

 Dr. Annandale procured this species.

According to Budde-Lund the first species known to science 

 of this remarkable genus were observed by Pallas in his Russian 

 journey, of which the account was published in 1771. The species 

 there described were named Oniscus ruder alis and Oniscus crenula- 

 tus. The latter maybe, in Budde-Lund's opinion, perhaps identi- 

 cal with Pore g//iO klugii, Brandt, 1833. Though vSavigny (pi. 13, 

 fig. 4) gave a few figures of the Egyptian species which Audouin 

 named Porcellio reaumurii, the first author to deal seriou.sly with 

 illustrations of the structural characters was Uljanin in his Rus- 

 sian treatise of the Crustacea of Turkestan, 1875. He describes 

 and figures Porcellio jedtschenkoi and P. elegans as new and P. 

 ornatus as the species so named by Milne-Edwards in 1840. Budde- 

 Lund refers all three of Uljanin' s descriptions to H emilepistus , 

 but leaves P. ornatus, Milne-Edwards, under Po;'Cc//^o and makes
