Family Glyphocrangonidae. 



Gli/2)/iocn()ic/o?i pjignax n. sp. 



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

 Timor. 520 m. Bottom soft, grey mud with brown upper layer. 

 2 females of equal size without eggs. 



The nearest allied form is Glyph. hastacauda Bate, the ante- 

 rior half of the 3i<l or dorso-lateral crest extending from near 

 the cervical groove forward and continuous with the orbital spine. 

 The rostrum, which is little shorter than the carapace and which 

 reaches by two-fifths its length beyond the antenna! scale, appears 

 u little less broad m proportion to its length than that of Glyph. 

 hastacauda: while in the latter the distance between the tip and 

 the line, uniting the two spines of the posterior pair, is three 

 times as long as the length of this line, in Glyph. pugtiax \t is 

 f'oar times as long. Lateral margins of the rostrum between the 

 two pairs of spines running straight hackward and parallel ivith 

 one another, in Glyph. hastacauda they appear here concave. 

 Orbital spine directed straight forward^ when the carapace is 

 looked at from above, and concealing in this position the bran- 

 chiostegal spine. 



Anterior moiety of dorsal crest divided into 6 or 7, posterior 

 into 4 or 5 low, obtuse tubercles. Anterior moiety of the 2n'l or
