edges near the base, and terminating with a hastate point to- 

 wards the apex ; feet varied with gray or blackish. ^7^.1. 3. 



Observations. This was found in September in a web, Uke 

 that of Angelena. This can be readily distinguished from 

 D. tenax, particularly by the form of its cephalothorax, in 

 which the head is not elevated as in that species. The second 

 pair of legs being sensibly the longest. This species could 

 almost be referred to Micrommata. It was found in March 

 upon the stump of a tree not far from a stream.

(Tenebrosse.) 3. DOLOMEDES TENEBROSUS. 

 Plate XIX. Fig. 10, 13. 



Description. Livid brown ; abdomen and cephalothorax 

 varied with blackish angular markings ; feet annulated with 

 blackish ; frequently measuring over four inches from the ex- 

 tremity of the first pair of legs to that of the fourth pair; male 

 with legs 1. 2. 4. 3. 



Observations. This spider, one of the largest of the whole 

 family, is very common in dark, retired places, hiding in cre- 

 vices during the day, and issuing at night from its retreat 

 for the purpose of seeking for prey. It does not seek the 

 vicinity of water near which it was never seen, but dwells 

 generally in elevated dry places. The female does not make 

 a web, but carries its cocoon, grasped with her cheliceres. 

 The cocoon is orbicular whitish, and of the size of a common 

 cherry. I have occasionally seen this Dolomedes in the day- 

 time, but it seemed always inactive, and easily captured. It 

 can be readily distinguished from D. albineus, by its having 

 no yellowish spot under the abdomen, and by the white hairs 

 on its legs. 



Habitat. Carolina, Alabama, Massachusetts ?
