318 Rev. O. P. Cambridge on a new 



ingly published in that newspaper on the 28th of August, 1875 

 (vol. xlvi. p. 257). The present article contains a full descrip- 

 tion of this interesting spider, of which both the genus and 

 the species appear to me to be new to science. The name 

 (Moggridgea) conferred upon the new genus will, I feel sure, 

 commend itself to those who have read the able work on 

 Trap-door Spiders written by the late Mr. J. Traherne Mog- 

 gridge ; and in thus connecting this interesting new genus 

 with the name of my kind and lamented friend, I desire to 

 give my sincere testimony to the great value and importance 

 of his too early interrupted observations on the habits of spiders 

 of the trapdoor-nest-building group. 



Family Theraphosides. 



Gen. nov. Moggeidgea. 



Generic characters. 



CephalotJwrax broad-oval, truncated before ; caput not 

 elevated beyond a general curved slope from the hinder part. 



Eyes eight, in the usual four pairs, forming (when looked 

 at from above and behind) a large, somewhat W-shaped figure ; 

 those of each lateral pair are widely separated ; the four lateral 

 eyes describe a transverse oblong figure whose front side is 

 longer than the hinder one, the latter being double the length 

 of the line formed by each lateral pair. 



Legs short, strong ; the tibiae and metatarsi of the first and 

 second pairs of a broad flattened form, armed on either side 

 near the underpart with strong spines : each tarsus ends with 

 three curved claws springing from a small claw-joint ; the 

 superior pair strong, and furnished with one or two teeth, the 

 inferior claw small ; no scopula on any of the tarsi. 



Fakes destitute of spines at their fore extremity on the 

 upperside. 



Maxillai short, strong, very divergent, cylindrical, with only 

 a small prominent point at their inner fore extremity. 



Labium short, but somewhat pointed at the apex ; the greater 

 part of the front (both of the labium and maxilla?) thickly 

 studded with small tooth-like spines. 



This genus is allied to Cteniza and Nemesia, but differs 

 from both in having no spines on the falces ; from the former 

 it differs in the comparatively low caput, and from the latter 

 in the wide separation of the eyes of each lateral pair. Like 

 the spiders of those genera, the present forms a tubular nest 

 closed with a hinged valve or lid.
