ber and various arrangement of their eyes, their 

 remarkable instincts, and curious structure, inter- 

 est every nice observer. For these and other rea- 

 sons 1 insert all the species of Gmelin, according 

 to his arrangement. As some species may be ob- 

 tained at all times of the year, they afford perpetu- 

 al materials for the exercise of students in natural 

 history. 



A. Eyes placed : : : : 



extensa, abdomen long, silvery-greenish ; legs 

 longitudinally extended. The head, thorax, 

 and legs, are reddish ; the abdomen is greenish 

 down the back ; the first pair of legs very long ; 

 the third very short. 



pallens, pale testaceous ; mandibles ferruginous, 

 with black claws. 



albidorsa, black and hairy ; abdomen obovate, 

 slender, two-horned ; thorax slender, compress- 

 ed laterally : back of thorax and abdomen cov- 

 ered with white hairs ; the white ridge on the 

 abdomen interrupted. Found at Troy, N. Y. 

 I propose it as a new species because it is not 

 described in Gmelin. It may be described by 

 other authors, which I have not seen. Eaton. * 



lobata, abdomen ovate, lobed, white, with double 

 brown lines at the tip. 



longimana, ferruginous ; abdomen long, cylindric- 

 al, brown ; the fore-legs very long, third pair 

 very short. 



regia, villous, cinereous, with a yellow band on 

 the front ; the legs are spinous. 



* As very few spiders have been examined and credited in this dis- 

 trict, I have spent a few hours this day (Sept. 15,) in examining those 

 I find about the Rensselaer School lot, I insert them as a beginning.
