by Wood-Mason in February 1S91, but in fig. 2 of the same Plate, representing the variety 

 andamanensis, these ridges agree with our specimens. I would finally remark that neither Spence 

 Bate, nor Wood-Mason or Alcock have made mention of the fine close tomentum, with which 

 the body is covered. 



General distribution: Off Matuku, Fiji Islands (Bate); north of the Kermadec 

 Islands (Bate); off Banda Island (Bate); Andaman Sea (Alcock); Bay of Bengal (Alcock); 

 Arabian Sea (Alcock).

This specimen not fully agrees with those referred to Glyph. regalis Bate and should 

 perhaps be regarded as a variety. Carapace and rostrum, taken together, are 33 mm. long, 

 the abdomen 43 mm., entire length 76 mm., while the rostrum that extends by one-fourth its 

 length beyond the antennal scale, measures 13 mm. This specimen is thus little smaller than 

 the male of Glyph. regalis Bate from Stat. 74. It differs from the specimens, referred to Glyph. 

 regalis, by the complete absence of the fine close tomentum, with which the body of 

 these specimens is everywhere covered, the body being quite naked and glabrous. Though 

 the number and arrangement of the crests, ridges and tubercles on carapace and abdomen are 

 exactly the same, they are much more prominent and more conspicuous both on 

 carapace and abdomen. The posterior moiety of the subdorsal crest is broken up into four 

 laterally compressed, truncate tubercles, of which the 2 nd or anterior but one is a little longer 

 than the i st or anterior and than the 3 rd , but nearly as long as the 4 th , while the i st is a little 

 longer than the 3 rd . The posterior moiety both of the dorso-lateral and of the lateral crest ends 

 anteriorly in an angle, which on the former is rectangular, on the latter more obtuse; the 

 posterior half of the dorso-lateral crest shows a tubercle just behind the middle and another 

 at the posterior end and these tubercles are quite distinct and as well-developed as the three 

 on the posterior half of the posterior moiety of the 4 th or lateral crest. One observes between 

 the posterior moieties of the 3" 1 and 4 th crest only one longitudinal line of granules, while in 

 the male from Stat. 74 still other granules are observed, close to the carinae. 



The telson extends by one-fourth its length beyond the uropods, when directed straight 

 backward, and the serrulations on the four edges are likewise more prominent. 



The vertically compressed spine, to which the anterior half of the 4" 1 or lateral crest 

 is produced, is comparatively larger, reaching forward to the level of the middle of the eyes 

 and nearly as far forward as the orbital spine ; it is directed more o b 1 i q u e 1 y outward and 

 much more acuminate. The orbital spine is only half as long as the branchiostegal 

 and directed obliquely upward, though not i n w ar d. 



In front of the anterior pair of spines the upper surface of the rostrum appears transversely
