Notaspis longilamellata, Michael. Jouvn. Roy. Microsc. Soc, 



ser. ii, vol. v, p. 391. 



Average length about '33 mm. 

 Average breadth about '18 mm. 

 Average length of legs (first pair) about '17 mm. 

 Average length of legs (second and third pairs) about 

 *16 mm. 



Average length of legs (fourth pair) about '18 mm. 



A small species, chiefly distinguished by the length 

 of the rostrum ; the length of the lamellas, which 

 approach near to the tip of the rostrum ; and the form 

 of the pseudo-stigmatic organs. 



Colour rather light yellow-brown. 



Texture polished, without any markings or punctures 

 that are visible with, say, 200 diameters amplification. 



Shape elongated, pyriform. 



Cephalothorax vei-y long, about five twelfths of the 

 whole length of the creature ; rostrum pointed, conical ; 

 the hinder part of the cephalothorax almost square. 

 Rostral hairs small, nearly straight. Palpi usually 

 showing almost at the tip of the rostrum. Lamella 

 mere thickened bars or ridges, they are very lon^, reach- 

 ing more than halfway along the rostrum ; for about one 

 third of their length (commencing from the pseudo- 

 stigmata) they approach one another at angles of 

 nearly 45° with the median line, then they suddenly 

 turn straight forward, and continue parallel until their 

 terminations. No cusps. No translamella. Two 

 short, paired ridges are situated at the base of the 

 cephalothorax between the pseudo-stigmata ; each com- 

 mences with a small, chitinous, almost half-moon- 

 shaped projection close to the abdomen and close to 



* Longus, long ; lamella, the lamella.
