Stat. 12. 7°15'S., 115°15'.6E. Bali Sea. 289 m. Bottom mud 

 and broken shells. 1 adult female without eggs, of wliicli the 

 rostrum and the right half of the carapace are much mutilated. 



Stat. 297. 10°39'S., 123° 40' E. Between the islands of Rotti 

 and ïimor. 520 m. Bottom soft, grey mud with brown upper 

 layer. 1 ovigerous female. 



A new species, related to Glyph. {Plasiocrangon) caecescens 

 W.-Mas., diiïering from it by the hepatic area hearing a small 

 obtuse tubercle, by the shape of the posterior moiety of the 

 dorso-lateral crest and by the body not presenting a general 

 crisp tuberculation. 



Rostrum of the female from Stat. 297, which is the type, 

 11,5 mm. long, carapace 13 mm., abdomen 30,5 mm., entire 

 length 55 mm. Surface of carapace and abdomen glabrous, naked. 

 Rostrum reaching by a little more than one-third its length 

 beyond the antennal scale, distal third curved upward. Median 

 ridge not elevated above the lateral margins. Anterior pair of 

 spines pointed, just reaching beyond the eyes, spines of the 

 posterior pair smaller, obtuse, situated immediately behind the 

 orbital margin. Orbital spine small, contiguous to the eye, bran- 

 chiostegal spine ticice as lomj^ directed straight and hon'zontaUy 

 forirard. Anterior moiety of dorsal crest divided into 5 low, ob- 

 tuse tubercles, of which the 1-t or anterior is the longest, pos- 

 terior moiety cut into two obtuse tubercles of equal length and 

 a little longer than the l^t of the anterior moiety; 3 tubercles, 

 like in other species, situated in a triangle between the anterior 

 end of the dorsal crests and the shallow rostro-gastric groove, 

 and () or 7 small granules between the two crests anteriorly. 

 Both the anterior and the posterior moiety of the subdorsal crest 

 are divided into 3 low, obtuse tubercles, of the 3 tubercles of 

 the posterior moiety the middle one is the longest. A longitii- 

 dhial bhiHt luJx'rcle on tlie hepatic area, nearly midway between
