Arr. XV. — Descriptions and Figures of the Araneides of 
the United States. By Nicnonas MancELLUs Hrwrz, 
Tuscaloosa, Alabama. 
[Concluded from page 35.] 
Genus Tyertpion Walckenaer. 
Characters. Cheliceres small, cylindrical; maxille widest 
at base, pointed towards the tip, inclined over the lip; lip 
small, very short, widest at base, subtriangular ; eyes eight, 
equal, four in the middle, nearly forming a parallelogram, two 
on each side, placed diagonally; feet slender, the first pair 
longest, the fourth and the second nearly equal, the third being 
the shortest. 
— Habits. Araneides sedentary, forming a web made of 
threads crossed in all directions. Cocoon of various shapes. 
Remarks. The subgenus Tuerrion contains many spe- 
cies, a majority of which are very small, and whose webs, 
made on the tops of weeds, in bushes, or in retired — 
are familiar to every one. 
I could not adopt any one of the families or tribes of Walck- 
enaer, and it is indeed a difficult matter to subdivide this sub- 
genus. Whether I have succeeded better will be decided by 
naturalists. 
Tribe I. GEMINATA. External eyes approximated. 
Spiders usually small. — :
