Mr. E. J. Miers on Malaysian Crustacea. 227 



tacea recently selected from the collection of the late Dr. P. 

 Bleeker, the eminent ichthyologist, for the British Museum. 

 This collection is of much interest, not merely on account of 

 the new and undescribed species included in it, which, as was 

 to be expected in a collection from a region so thoroughly 

 worked, are not very numerous, but also on account of the 

 many species it contains which have been hitherto desiderata 

 to the Museum collection. Amongst these are several of the 

 Maioidea, and fourteen out of sixteen species of Isopoda 

 (Cymothoidea) parasitic on fishes, described by Dr. Bleeker in 

 his two memoirs, entitled " Sur les De'capodes Oxyrhinques 

 et les Isopodes Cymothoadiens de l'archipel Indien" *. 



To avoid needless repetition I have seldom given references 

 to the literature, except in those not unfrequent cases where I 

 have been enabled to correct the synonyma or bring together 

 species which appear to have been based on characters of in- 

 sufficient value. 



The exact localities were unfortunately not marked on all 

 the bottles in Dr. Bleeker's collection ; but those which were 

 not more particularly labelled were marked as containing 

 " Crustacea Indo-Archipelagica ;" and therefore no doubt can 

 be entertained of the Malaysian habitat of all the species. 



OXYEHYNCHA vel MAIOIDEA. 



Doclea brachyrhynchus. 



Doclea brachyrhynchus, Bleeker, Act. Soc. Indo-Neerl. ii. p. 14 (1857). 

 Doclea sebce, Bleeker, /. c. p. 13 (1857), junior. 



An adult male, agreeing well with Bleeker's description, is 

 in the collection, without special locality. A second male 

 example agrees with the description of Doclea sebm • and 

 a comparison of the two specimens leaves little doubt in 

 my mind that this latter species must be united with D. 

 brachyrhynchus as having been established upon younger 

 examples. The only character by which D. sebce is distin- 

 guished, viz. the somewhat shorter, slenderer chelipedes, with 

 fingers meeting along their inner margins, cannot be considered 

 of specific value. 



Doclea macracantha. 



Doclea macr acanthus, Bleeker, Act. Soc. Indo-ne'erl. ii. p. 10 (1857). 

 ? Doclea microchir, Bleeker, I. c. p. 11 (1857), junior ? 



A small male example, without special indication of locality, 

 agrees very well with Bleeker's description. As far as can 

 be judged from the description, D. microchir, Bleeker, which
