requiring further investigation, and at present I am not prepared 

 to give an opinion on it. 



Gtltciphagtjs plattgasteb, u. sp. (Plate XXXIV., and 

 Plate XXXV. figs. 1-5.) 



Colour, when just emerged, pure white, afterwards cream- 

 white to parchment-colour, or with a pinkish shade ; the male 

 sometimes a little darker ; legs and rostrum light pinkish-brown ; 

 all the colours opaque. 



Texture of the body rough and granulated, like shagreen. 

 The male is the rougher. The result of this is that all the edges 

 of the body appear to be, and actually are, covered with a thickly- 

 set series of irregular projecting dots, or short blunt points. 



Female. 



Cephalothorax small, short, and conical, with curved sides ; 

 less than one sixth of the total length of the creature, as seen 

 from above. Eostrum or epistome, rather obtuse, forming a 

 hood above the mandibles, which project, giving a pointed ap- 

 pearance. The two rostral hairs are thick, stiff, 'and strongly 

 curved downward ; further back (on the dorso-vertex) are two 

 powerful spikes directed forward, springing from large papillae 

 placed near together and almost close to the anterior margin of 

 the abdomen. Mandibles (fig. 7) large, short, tridentate. Maxillae 

 (so-called) (fig. 6, mx) plain, not dentate, and of clear colourless 

 thin chitin. There is a well-marked chitinous skeleton supporting 

 the labial parts and projecting inward, as indicated in fig. 6. Palpi 

 three- jointed, lower joint anchylosed to labium (Plate XXXV. 

 fig. 4). Lingula triangular, somewhat spoon-shaped, of clear 

 membrane. 



Legs very thin in proportion to the size of the creature, rather 

 short ; fourth pair passing the hind margin by rather more than 

 half the length of the tarsus. The two front pairs spring from 

 large, rounded, chitinous projections at the edge of the lower 

 part of the cephalothorax, having rough chitinous knobs at their 

 posterior angles ; the third and fourth pairs are set well under
