The name granulosis is probably owing to a slip of the [jen for granulosa. 



General distribution: The two type specimens of Glyph, granulosis were taken 

 by the "Challenger" between New Guinea and the Admiralty Islands, while Glyph, priononota 

 is still only known from the Arabian Sea.

Stat. iS. March 18. 7°28'.2S., II5°24'.6E. Bali Sea. 1018 m. ISottom fine grey mud. i adult, 



very mutilated specimen and i young female. 

 Stat. 45. April 6. 7° 24' S., ii8°is'.2E. Flores Sea. 794 m. Bottom fine grey mud, with some 



radiolariae and diatonies. 6 females of different size, 2 of which are ovigerous. 



A new species related to Glyph, sicaria Faxon from the Gulf of Panama and pertaining 

 to that Section of the genus, in which the anterior moiety of the 4''' or lateral crest is divided 

 into two parts produced anteriorly into moderate spines, the anterior of which falls far short 

 of the anterior border of the carapace. 



The two largest specimens are the egg-laden females; of the larger the carapace, mea- 

 sured in the middle line, is 27 mm., the rostrum 24,3 mm. long, in the other these numbers 

 are for both rostrum and carapace 21,5 mm.; in the third female carapace and rostrum are 

 also both 20 mm. long, in the fourth the carapace 20,5 mm., the rostrum 19,5 mm., in the 

 fifth these numbers are, in the same succession, 15 mm. and 17,75 mm-, in the si.xth, finally, 

 12 mm. and 13,5 mm. In the adult specimen from Stat. i8, which has lost all appendages, the 

 carapace is 24 mm. long, the rostrum 23 mm., in the young female these numbers are for the 

 carapace 13 mm., for the rostrum 14 mm. In the full-grown ovigerous specimen the rostrum 

 is thus slightly shorter than the carapace, in those of medium size both are of equal or subequal 

 length and in the smallest individuals the rostrum is distinctly longer than the carapace, as is usually 

 the case. The largest specimen, of which the abdomen is 57 mm. long, has a length of 108 mm., 

 the youngest female is 54 mm. long. Like in other species the rostrum, that reaches by almost 

 half its length beyond the tip of the antennular peduncle, is slightly directed downward for 

 two-thirds its length, the distal third is feebly curved upward, the tip, however, does not reach 

 to the level of the upper border of the carapace. Like in Glyph, sicaria the rostrum is armed 

 with two pairs of small spines, those of the anterior pair are acute, situated a little in advance 

 of the eyes and reaching with their tips to the far end of basal antennular article, the spines 

 of the posterior pair are only half as long, subacute and placed immediately in advance of the 

 orbital margin ; the distance between the tips of the spines of the posterior pair is just as long 

 as the distance between the line that unites these spines and that which unites the spines of 

 the anterior pair; the margin between the two pairs is slightly concave. The median carina, 

 traceable to the small acute tooth at the anterior boundary of the gastric region, is on the 

 distal upturned part slightly elevated above the lateral margins and on each side of it the 

 rostrum is, in front of the anterior pair of spines, transversely corrugated, though not 

 on the distal upturned part; the flattened or slighdy grooved, lower border is on the distal 

 upturned part distinctly carinate in the middle line.
