middle. Antennal peduncle slender, a little shorter than the scale. The antennal scale of the 

 male is comparatively a little broader, being almost twice as long as broad, and is slightly 

 shorter in proportion to the carapace, rostrum included, measuring ^~ their length ; the spine 

 on the outer margin is more distinct and the antennal peduncle, nearly as long as that of the 

 inner antennae, reaches a little beyond the scale. 



The external maxillipeds are but little shorter than the antennal scale. The legs of the 2 nd 

 pair are distinctly shorter than any of the last 3 pairs and reach only to the middle of the antennal 

 scale: the legs of the 3 rd and 5" 1 pair extend to the tip of the scale, those of the 4 th slightly 

 beyond it. Like in other species, the propodi of the two last pairs (Fig. 57^, 57/) end in a brush 

 of setae ; the dactyli of the 3 rd (Fig. 57^) and 5 th (Fig. 57/) pair are almost half as long as their 

 propodi, those of the 4" 1 (Fig. 57^) measure two-thirds the latter: the dactyli are lanceolate, 

 pointed, grooved along their whole length in the 4 th and 5" 1 pair, only on the distal halfin the 3 rd . 



Eggs few in number, orange or rusty-coloured, longer diameter 2 mm. 



Rostrum, carapace and abdomen are in the larger male respectively 12 mm., 14 mm. 

 and 29 mm. long, entire length 55 mm.; in the ova-bearing female these numbers are in the 

 same succession 12 mm., 16 mm., 36 mm. and 64 mm. 



The male and female from the Arakan coast, that were referred in- March 1905 by 

 Mac Gilchrist with some doubt to Glyph. longirostris (S. I. Smith) (in: Annals Mag. Nat. Hist. 

 Ser. 7, Vol. XV, March 1905, p. 238), probably belong to Glyph. assimilis, though the tubercles 

 of the abdomen are described as "broad flat low", which is not the case in this species; the 

 eyes were also somewhat smaller, because in the Indian specimens the length of the carapace, 

 including rostrum, measured about S^o-times their greater diameter. 



Glyph. longirostris (S. I. Smith) differs i° by its much larger size, 2 by the absence of 

 any tracé of the anterior portion of the 3 vd or dorso-lateral crest, 3 by the orbital spine being 

 directed much more obliquely outward, 4 by the tubercles on the abdominal terga being larger 

 and fewer in number, while they are apparently wanting on the side-plates of the 2 nd — 4 lh 

 somites, 5 by the shorter dactyli of the three posterior legs (confer: S. I. Smith, Report on the 

 Decapod Crustacea of the Albatross Dredgings off the East coast of the United States during 

 the summer and autumn of 1884. Wash. 1886, p. 51, PI. VIII, figs. 1, 2, PI. IX, figs. 3, 4, 5). 



Glyph. nobilis A. M.-Edw., finally, from the Antilies bears probably traces of the anterior 

 portion of the dorso-lateral carina, for in the short description (in: Annal. Scienc. Nat., Zoölogie, 

 Juin 1881, p. 5) A. Milne-Edwards says: "Les proéminences rugueuses de la carapace et de 

 1'abdomen sont beaucoup plus nombreuses, elles existent sur la région hépatique qui est presque 

 lisse chez Ie Gl. spinicauda". This species, however, apparently differs from Glyph. assimilis by 

 the tubercles of the dorsal and subdorsal crests of the carapace being spiniform and pointed, 

 furthermore by the telson which is much longer than the uropods and of which the distal half is 

 turned upward. A new description and better figures of this species are, however, indeed necessary.
