carinae end in this species in a small spinule, in adult specimens, however, one or more of 

 these spinules are often worn off. Sometimes 3 or 4 small tubercles or granules are observed 

 just below the posterior moiety of the 4"^ or lateral carina, posteriorly, though they are often 

 wanting at all. Usually the two dorsal crests converge regularly backward, but sometimes the 

 gastric portions run nearly parallel. The dorsal crests are usually finely serrulate or crenulate, 

 but sometimes the gastric portion of these carinae appears more or less smooth. 



This species is easily distinguished by the anterior portion of the 3"' or dorso-lateral 

 carina or post-antennal crest that extends from the orbital spine backward to the cervical 

 groove; sometimes in young specimens this crest can only be traced to midway between the 

 orbital margin and the cervical groove and such specimens in this case closely resemble Glyph, 

 unguiculata W.-Mas., which is the nearest allied form and perhaps identical with Glyph, 

 acuminata Bate, that was obtained by the "Challenger" near the Fiji Islands. 



The eyes of the young specimens from Stat. 314 show the same dark slate colour 

 (in spirit) as those of the adult, excepting one specimen long 34 mm., in which they are of a 

 light leather colour. 



Eggs almost globular, 3 mm. broad. 



General distribution: Off Japan (Bate); Bay of Bengal, off Ceylon (Alcock).

A new species closely related to Glyph, hastacauda Bate, acuminata Bate and nobilis 

 A. M.-Edw. 



In its outer appearance Glyph, pugnax resembles Glyph, hastacauda Bate. Rostrum 

 little shorter than carapace and reaching by two-fifths its length beyond the antennal scale; it 

 appears a little less broad in proportion to its length than the rostrum of Glyph, hasta- 

 caiida, because, while in the latter the rostrum is three times as long as the distance between 

 the two posterior teeth that are situated above the orbital margin, in this new species it is 

 four times that distance. Like in Glyph, hastacauda the spines of the anterior pair are a 

 little larger and more pointed than those of the posterior, but the anterior pair is implanted 

 distinctly in front of the eyes, just behind the distal extremity of basal antennular 

 article, while in Glvph. hastacauda the spines of the anterior pair reach not or hardly beyond 

 the eyes; the lateral margins of the rostrum run in Glyph, pugnax., between the two pairs of 

 spines, straight backward and are therefore parallel, but in Glyph, hastacauda the 

 lateral margins are here distinctly concave. In both species the two pairs of rostral 

 teeth are rather small. The median ridge, which, like in Glyph, hastacauda, is slightly elevated 

 above the lateral margins in front of the anterior pair of spines, ends in a small subacute 

 tubercle near the transverse basal groove that separates the rostrum from the gastric region,
