410 Mr. J. Blackwall on new Species of Spiders, 



tinged with olive where that of the female is dull brown ; and 

 the yellowish-white oval zone on the upper part is much more 

 distinctly marked. The cubital and radial joints of the palpi 

 are short ; the digital joint has a short oval form ; it is convex 

 and hairy externally, concave within, comprising the palpal 

 organs, which are highly developed, complex in structure, 

 with a large and somewhat crescent-shaped piece at their ex- 

 tremity, which has a pale-yellowish hue ; between the horns 

 of the crescent, the outer one of which is the longer and more 

 pointed, a large, curved, brown, prominent process projects, 

 which is directed backwards ; it extends to the base of the 

 humeral joint, is hollowed at its extremity, on the under side, 

 has a strong, brown, pointed process at its base, on the inner 

 side, and a long, slender, upright one, of a pale hue tinged 

 with red, towards the outer side. 



I have included this spider, provisionally, in the family 

 Drassidae ; but it presents such a singular combination of cha- 

 racters that it is difficult to determine precisely the place it 

 should occupy in a systematic arrangement of the Araneidea. 



In connecting the name of the Barao do Castello de Paiva 

 with this Clotlio (numerous specimens of which, both males 

 and females in various stages of growth, were taken in the 

 Island of TenerifFe), I avail myself of the opportunity to ex- 

 press my sense of the obligation I am under to him for the 

 many interesting species of spiders with which he has favoured 

 me. 



Family EPEi'RiD^. 



Genus EPEi'RA, Walck. 

 Ejpeira gracilipes. 

 Epeira gracilipes, Blackw. Ann. & Mag-. Nat. Hist. ser. 3. vol. x. p. 437. 



An adult male of this species was captured in the Island of 

 Bermuda. 



Tribe Senoculina. 



Family Scytodid^. 



Genus Scytodes, Latr. 



Scytodes pallida. 



Scytodes pallida, Blackw. Ann. & Mag. Nat. Hist. ser. 3. vol. xvi. p. 100. 



An immature female of Scytodes pallida was taken in the 

 Island of Bermuda. 



For the spiders from the Island of Bermuda I am indebted 

 to the kindness of Captain Francis Lyon, of the Eoyal Artil- 

 lery, and for those from the Island of TenerifFe to the Barao 

 do Castello de Paiva.
