PsEUDORHOMBUS, Blccker. 

 Three species of Pseudorhomhus are represented in the collection, viz. : — 

 Pseudorhombus arsius, Bleeker. 

 Pseudorhomhus javanicus, Bleeker. 

 Pseudorhomhus russellii, Gray. 



As is the case in British Pleuronectidae, there is a considerable variation in 

 colour and marking within the limits of a single species. This is especially notice- 

 able in the case of the specimens of Pseudorhombus arsius. The presence of interme- 

 diate specimens between the extreme colour varieties, however, renders it certain 

 that only one species is represented. 



Pseudorhomhus arsius, Bleeker. 



This species is distinguished from the nearly related P. javanicus by the larger 

 number of dorsal fin rays (over 70) and the enlarged anterior teeth.

Pseudorhomhus javanicus, Bleeker. 



Day in his description of this species says ''A well-developed pre-anal spine," 

 whereas in P. arsius the " pre-anal spine, when present, is but slightly apparent." 



According to my observations this spine is occasionally well-developed {vide 

 Nos. F ^'^^^ or F --r-, P^j and more often absent {vide other specimens). Possibly
