It is not iinpossible that this species is only a young form of Parathemisto ohlivia, 

 Kroeyek, but after the detailed description of the second pair of perasopoda given by 

 Spence Bate in 1862 we must at present consider it is a species of its own, and accept 

 for it the name proposed by A. Merle Norman. 



Spence Bate's description runs: 



»Cephalon transversely ovate; aBterior margin flattened; pigment of the eyes occupying 

 only part of the anterior portion of the cephalon. Superior antennas as long as the cephalon, 

 having the peduncle very short; flagellum broader at the base than the peduncle, tapering, sub- 

 ulate, sharp, uniarticulate, but showing incipient signs of articulation. luferior antennas longer 

 than the superior, slender; peduncle short (two joints only exposed); flagellum long, having the 

 first articulus as long as the three others. Gnathopoda subequal, short; first pair tlie shorter, 

 cylindrical, robust; carpus scarcely produced inferiorly; propodos not so long as the carpus, su- 

 perior margin arcuate, inferior margin straight, serrated anteriorly with a row of small denticles; 

 dactylos short, obtuse; second pair having the carpus slightly produced inferiorly, but not ante- 

 riorly, and fringed with a few hairs; propodos as long as the carpus, but not so stout; dactylos 

 half the length of the propodos, arcuate, sharp. First two pairs of pereiopoda long, mucli longer 

 than the gnathopoda, having the carpi posteriorly dilated and fringed with a few hairs; propoda 

 slightly arcuate, longer than the carpi, cylindrical; dactyla long and sharp. Third and fourth 

 pairs of pereiopoda subequal; third pair longest, having the basos not dilated; carpus long; pro- 

 podos nearly twice as long as the carpus, slender, anteriorly fringed with a comb-like row of 

 cilia; dactylos long, slightly curved, sharp: the fourth pair resembles, but is slightlj' shorter than, 

 the third; and the fifth pair is still a little shorter than the fourtli. Posterior pair of pleopoda 

 longer than the preceding, and having the margins of the rami serrated. Telson lanceolate. The 

 colour, as well as could be recognized from a dead specimen, is corneous, with some black 

 stellate markings on the dorsal surface of the pereion.» 



From the description given by Spence Bate and Westwood in 1868 I reproduce 



only the »Specific character» and a fcAv passages, the rest being essentially the same as 



in the description of 1862: 



»Specific cliaracter. Superior antennas as long as the depth of the cephalon. Inferior an- 

 tennas longer than the superior and terminating in a multi-articulate flagellum. Gnathopoda
