214 Records of the Indian Museum. [Vol. XXIV, 



The species was very common in the Gulf of Manaar, among 

 weeds in shallow water and also on the coral reefs. 



The species was described from Ousima I. (Stimpson) and has 

 been recorded from Ternate and Pulo Edam (deMan), Trincomalee 

 (Miiller), Cheval Paar (Pearson), Zanzibar (Lenz), Dar-es- Salaam 

 (Ortmann) and the Red Sea (Nobili, Balss).

This species is very closely related to P. grandis. I have 

 examined the type, an ovigerous female in the Cambridge Museum, 

 but my work at that time was not sufficiently advanced to 

 enable me to make full use of the opportunity. I noted, however, 

 that in the telson of the type specimen both pairs of dorsal spines 

 ate situated in the posterior half, whereas in the specimens I have 

 referred to P. grandis the foremost pair is situated in the anterior 

 half. The position of_ these spines affords a valuable specific 

 character in some species of Periclimenes (cf. P. brevicarpalis and 

 P. inornatus) and I conclude, therefore, that P. vitiensis is possibly 

 a distinct species. The specimens from Coetivy in the Seychelles 

 subsequently referred by Borradaile to P. vitiensis should be 

 re-examined, for it is not improbable that they belong in reality 

 to P. grandis. 



P. vitiensis was described by Borradaile from Viti Levu, Fiji.

This species appears to be closely related to Paulson's P. ele- 

 gans } which is described below. According to Borradaile's descrip- 

 tion and figures it differs (i) in its straighter rostrum, armed 

 with only 2 teeth below, (ii) in the greater proportionate length 

 of the first peraeopods which outreach the antennal scale by the 

 chela and half the length of the carpus, and (iii) in the much 

 more slender and proportionately longer carpus of the second 

 peraeopods, about 6 times as long as wide according to the figure 

 and a little longer than the merus. 



P. affinis is recorded from Salomon I. in the Western 

 Indian Ocean.
