192 Messrs. J. Wood-Mason and A. Alcock on 



length 90*5 millim. ; width between points of spines of lateral 

 crests 20 millim. 



A single adult (ovigerous) female was subsequently obtained 

 in lat. 20° 17' 30" N., long. 88° 50' E., in 193 fathoms, in 

 company with Nephropsis Garpenteri.~\ 



(2) Species with the anterior moiety of the fourth crest 

 divided into two parts produced anteriorly into moderate 

 spines, the anterior of which never approaches the level of 

 the supraorbital margin, and with the ridges and other eleva- 

 tions of the dorsal integument more or less sharp and roughly 

 tuberculose. — G. scidptus, S. I. Smith, G. granulosis, G. 

 podager, and G. rimapes, Spence Bate, and the following : — 



11. Glyphocrangon priononota, sp. n., Wood-Mason. 



Allied to G. sculptus and G. granulosis, but distinguishable 

 at a glance from the former by the great strength and dis- 

 tinctness of all the crests, but especially of the dorsal and 

 subdorsal (first and second), which are strongly toothed; by 

 the posterior moiety of the sublateral (third) crest not ter- 

 minating anteriorly in a tubercle ; by the anterior moiety of 

 the lateral (fourth) crest being merely divided by a notch and 

 not reduced to two spines ; by its more strongly tuberculate 

 abdomen ; by the pleura of the fifth abdominal somite being 

 bispinose instead of trispinose ; by the form of the dactylo- 

 poditcs of the fourth and fifth pair, which are simply pointed; 

 by the teeth at the base of the rostrum being larger than the 

 teeth of the rostrum itself; and probably in other details. It 

 apparently agrees with G. granulosis in the strength and 

 armature of the dorsal and subdorsal crests, but it differs in 

 its narrower body ; in the rostrum extending fully one third 

 of its length beyond the antennulary peduncle ; in the poste- 

 rior moieties of the sublateral and lateral (third and fourth) 

 crests not being tuberculose, and the former of them not 

 ending anteriorly in a strong cusp ; and in the spines of the 

 anterior moiety of the lateral (fourth) crest not being so 

 large. From comparison with G. podager and G. rimapes it 

 is altogether excluded by the simple dactylopodites of its 

 fourth and fifth pairs of legs. 



Two males and one female from Station 104, 1000 fathoms. 



Colours in the fresh state deep pink ; colour of eyes in 

 spirit dark purple. 



Length of rostrum 21 '75 millim., of carapace from orbital 

 to posterior margin 22 millim., of abdomen 59 millim. ; total 

 length 107 millim.
