[Hentz. 



Clubiona piscatoria. Fig. 29, eyes. The two external nipples 

 of the abdomen are the longest ; the body is of the same color be- 

 neath as above. Taken in April. 



Clubiona ? saltabunda. Fig. 19, eyes. Prof. Hentz was in 

 doubt whether this was a Clubiona or a Tef/enaria. 



Clubiona tranquilla. Fig. 85, eyes; fig. 102, trophi. Legs ar- 

 ranged 1, 2, 4, 3. Taken in Alabama and Carolina. 



Herpyllus bilineatus. Of the six nipples, four were placed 

 around the anus, and two formed a fork on both sides of the anus. 

 Taken in May. 

 Herpyllus cruciger. Taken in July. 



" ecclesiasticus. Legs arranged 4, 1, 2, 3. This, 



and others placed in this genus, may belong to the genus Diplotoxops 

 of Mr. Rafinesque, but as he makes the first pair of legs longest, and 

 his generic description is incorrect in many respects — for instance in 

 deriving a character from the palpi, which is as a rule nothing but a 

 sexual distinction — his name has not been adopted. 



Herpyllus longipalpus. Legs arranged 4, 1, 2,3. 



" marmoratus. First, second and third pair of legs 



pale, thighs black with the tip white, third and fourth with bands of 

 white scales. Taken in July. 



Herpyllus ornatus. It is difficult to catch. Taken in July 

 and August. 



Herpyllus variegatus. The description of this in the Boston 

 Journal of Natural History, Vol. V., p. 458, states that Southern 

 specimens had the " external eyes " " placed nearer together "; it 

 should have said the external eyes of the posterior line were ad- 

 vanced anteriorly ; the specimens from the South were also smaller. 

 Herpyllus vespa. Taken in March. 



Tegenaria medicinalis. Fig. lio, palpus of $ a, upper hook- 

 ft, lower hook and its membranous meatus above ; c, middle sphenoidal 

 piece ; c?, third hook corresponding to the fourth hook i ; e, bristle which 

 is usually curled between the first and second hook ; /, base ; i, fourth 

 hook. The upper and lower hooks are parallel like two fingers; 

 whilst the third and fourth are opposed to them ; all forming a com 

 pound hook which must retain the female organ whilst the little bris- 

 tle e stirs and conveys the sperma. That fluid flows from an orifice 

 at the base of the lower hook, between it and the membrane situated 

 on its upper part. The middle piece articulates with all the other 

 parts except the base. The bristle and the third hook articulate to- 

 gether and with the base. The fourth hook seems to be a process of 

 the upper hook. The lower book articulates with the middle piece, 

 and seems to have no motion of its own. The upper hook articulates
