is essentially identical with it, and the abdomen only differs in essen- 

 tial points from that of P^ophrynus in characters which ally it to the 

 Architarboidae. 



EopiiRYNUS "Woodward. 



Cephalothorax triangular ; its dorsal surface tumid, completely 

 broken into great tuberculate bosses, arranged in a lateral row down 

 either side and a median row dividing in two at the posterior margin. 

 Dorsal surface of abdomen with two lateral rows of larofe rounded 

 tubercles and a median row of large stellate tubercles, besides being 

 sometimes divided by longitudinal sutures into median and lateral 

 fields.

The discovery of new remains of this curious arachnid led Mr. 

 Woodward to notice the incorrect reference of similar remains by 

 Buckland and Samouelle to the Coleoptera. As stated above, it seems 

 probable that the other species referred in the same place to the 

 Coleoptera will prove to be an Architarbus. Woodward neither 

 figures nor makes mention of any fracture of the dorsal plates in his 

 very excellently preserved specimen ; but as this exists in the next 

 species, it would seem probable that they might have been over- 

 looked.

The generic name is incorrectly spelled Euphrynus.

 two pairs of legs slender, the hinder stout and broad. Abdomen com- 

 posed of nine joints, the basal three rather short, the others subeqnal

 about twice as long as broad. Postabdomen composed first of two 

 joints together hali as long as broad, one third as broad as the abdo- 

 men, next of a single quadrate joint, followed by the thread, about 

 one fourth or one fifth as broad, of unknown length, with numerous
