Basal lamina very wide and short. 



Coxœ of maxillary feet also very wide and short; claw of maxil- 

 lary feet unarmed. 



Tergites rugose, not bisulcate. 



Sternites entire, without pores. 



Very many pleural sclerites, as many as five separating the stig- 

 matiferous sclerite from the tergite. 



Anal pleurœ very much inflated , thickly covered with minute pores ; 

 anal legs composed of six segments; unarmed. 



Unfortunately owing to scarcity of material I have been unable to 

 put the mouth parts to an anatomical investigation sufficient to record 

 the characters they present. However, the palpi of the third pair of 

 jaws in this second specimen are not contorted as they are in the 

 type of G. cumingii. The character, therefore, is not generic and can 

 only cautiously be regarded as specific considering the material that 

 has been examined. 



22. Gonibregmatus insularis , n. sp. PI. XIX, fig. 9 — 9b. 



Island of Saleyer, a single 9 specimen. 



Length 97 mm.; 131 pairs of legs. 



Colour a uniform testaceo-ochraceous tint. 



Head-plate about as long as wide, with nearly straight posterior 

 border, lightly convex lateral borders and angulate anterior border; 

 obsoletely punctured. 



Antennœ thick, with subquadrate segments; shortly and feebly 

 hirsute. Basal-plate wider than the head-plate, more than six times 

 as wide as it is long ; prebasal plate visible ; 1 st tergite slightly wider 

 than the basal plate and much wider than the second tergite. 



Maxillary coxœ entire, wide, about three times as wide as 

 long; the anterior border mesially very lightly concave, not dentate; 

 lateral margin reduced to a minimum by the convergence on each 

 side of the anterior and posterior margins; claw of the maxillipede 

 very stout, somewhat triangular, curved, with blunt point; the 

 maxillary feet largely overlapping the head -plate at the sides but not 

 in front. 



Tergites entire, lightly rugulose, not very noticeably impressed at 

 the sides; sternites entire, almost smooth. Anal-tergite and its pre- 

 scutum fused , very much compressed by the anal pleuras ; anal tergite
