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



first postabdominal segment are straight ; in the four following 

 segments they are curved backwards, and are surmounted by 

 a second smaller spine, situated at the postero-lateral angles 

 of the segment ; in the sixth segment there are no postero- 

 lateral spines. The distal end of the merus of the ambu- 

 latory legs is armed with two spines. The colour (of 

 specimens dried and in spirits) is bluish purple or reddish ; 

 the carapace, larger spines, antennas, and segments of the 

 postabdomen are covered with numerous pale yellow spots ; 

 and the legs are marked with longitudinal lines of the same 

 colour, which are sometimes broken into irregular spots or 

 blotches. 



Indo-Malayan seas (an adult male without locality). 



Of this beautifully marked species there are also in the 

 Museum collection two adult males from Aneiteum (New 

 Hebrides), and a smaller female from the Mauritius. A. 

 M. -Edwards also records it from Zanzibar. 



In the female the spines on the sternum, between the bases 

 of the fifth ambulatory legs, which are prominent and well- 

 developed in the males, are present, although of much smaller 

 size. The carapace in all the specimens is more or less 

 covered with short stiff hairs, arranged in short lines in front 

 of the bases of the spines. 



The pale yellow spots on the postabdominal segments are 

 of unequal size ; about four on each segment are larger ; and 

 of these the largest is situated on each side above the base of 

 the lateral spines. 



Enoplometopus pictus, A. Milne-Edwards. 



Amboina (an adult male). 



The example before me of this very rare and interesting 

 species, which was previously unrepresented in the Museum 

 collection, agrees in every particular with the description and 

 excellent figure of M. A. Milne-Edwards (" Faune Carcinolo- 

 gique," in Maillard's ' Notes sur l'ile de la Reunion,' Annexe 

 F, p. 14, pi. xix. fig. 1), except only that the chelce of the 

 anterior legs are represented as somewhat broader in propor- 

 tion to their length, with the tubercles of the upper surface 

 more developed — characters on which it would certainly not 

 be safe in any case to separate the two as distinct. 



Perhaps the nearest ally of the genus Enoplometopus is to be 

 found in Eutrichocheles modestus — a Malaysian form only 

 known to me from Herbsfs original figure and description 

 (Naturg. Krabbenu. Krebse, ii. p. 173, pi. xliii. fig. 2, 1794), 

 and from the few remarks of Prof. Wood-Mason (Proc. Asiatic 

 Soc. Bengal, p. 231, 1875), by whom the species has lately
