PULJIONARLE. 309 



be no mistake, in the number of the eyes, which is but four. See 

 Ann. Gener. des Sc. Phys., VIII, p. 88. 



A second subgenus, which also is only known to us by description, 

 is the 



Palpimanus, Duf., 



Described by M. Dufour in the Ann. des Sc. Phys., V, Ixix, 5, and 

 which appears to him to be intermediate between Eresus and Salticus. 

 The disposition of the eyes is about the same as in the first of these 

 two subgenera. The ligula is similarly triangular and pointed, and 

 the jaws are still dilated and rounded at the end ; but, according to 

 M. Dufour, they are inclined and not straight like those of the Eresi. 

 The terminal joint of the anterior tarsi is inserted laterally, and has 

 no hcoks. 



He describes one species, the Palpimane bossu. It never 



jumps, walks slowly, and is found under stones in Valencia, 



where, however, it is extremely rare. 



A new species has been discovered by M. Lefevre in Sicily, 



which appears to me to belong to this genus. 



In the two following subgenera there are always eight eyes ; the 

 jaws are straight. 



Eresus, Walck. 



Four eyes forming a small trapezium near the middle of the ante- 

 rior extremity of the thorax, the other four on its sides forming a 

 similar but much larger figure. The ligula is triangular and pointed. 

 The tarsi are terminated by three hooks*. 



Salticus, Lat. — Attus, Walck. 



Four eyes, the two intermediate of Avhich are the largest, on the 

 anterior part of the thorax in a transverse line, and the other near its 

 lateral edges, two on each side ; they also form a large square open 

 behind, or a parabola. The ligula is very obtuse or truncated on the 

 summit. There are but two hooks to the extremity of the tarsi. 

 Several of the males have very large chelicerae. 



The thorax of some are very thick and sloping, (en talus) and 

 much inclined at base. 



Salt. Sloanei; Aranea sanguinolenta,lj. Black; a white line 

 formed by down on each side of the thorax ; the abdomen of a 

 cinnabar-red, with an elongated black spot on the middle of the 

 back. South of France, on stones f .

 species ; one of them ; the Eresus acanthophilus — YI, xcv, 3, 4 — is my Erese raije of 

 the Nouv. Diet. d'Hist. Nat. ; the other, Eresus imperialis — V, Ixix, 2 — is closely 

 allied to the Aranea nigra, Petagna, above quoted. These two species are figured 

 in the Faune Frangaise, Aran., pi. IV, 3, 4, 5. See also on same plate, fig. 7, the 

 Erese cinabre.
