minent and cylindrical; it is slightly convex above, projects a 
little over-the base of the cephalothorax, and is clothed with 
adpressed grey hairs; the upper part is of a yellowish-brown 
colour, with some long blackish hairs at its extremity, in front, 
and an obscure, brown, fusiform band extending thence, in the 
medial line, about half its length; the under part is of a pale 
dull-yellowish hue; the basal joint of the spinners has a yel- 
lowish-white tint, and the other joints of those organs are of a 
brownish-black colour. 
I have much pleasure in connecting with this Drassus the 
name of Mrs. Louisa E. Collings of Serk, who on various occa- 
sions has obligingly forwarded to me numerous interesting spe- 
cies of Araneidea captured in that island, and among them 
several specimens of this Drassus in different stages of growth, 
but all im a state of immaturity. |

Genus VELEDA, Blackw. 
Veleda pallens. 
Veleda pallens, Blackw., Ann. & Mag. Nat. Hist. ser. 3. vol. ix. p. 372. 
I am informed by Frederick Pollock, Esq., of Thurlow, who 
has resided in the island of Madeira, that he has found speci- 
mens of Veleda pallens in that island, associated with Nephila 
aurelia, at an elevation of 800 feet above the level of the sea. 
This species, he remarks, constructs a horizontal geometric 
snare, and invests one of the radii with a loosish thread. Should 
a young Nephila venture to trespass on the snare, the Veleda 
rapidly approaches it with a vibratory motion, and envelopes its 
victim with silk drawn from the spinners by a lateral motion of 
the posterior legs.

Two females of this species (now first recorded as British) 
were found under a stone, in a pasture near Hendre House, on 
the 16th of June, 1864, They were placed in a phial ; and one 
of them constructed therein two balloon-shaped cocoons of white 
silk, of a loose texture, the larger of which measured } of an 
inch in diameter, and contained about thirty spherical eggs of a 
pale-yellow colour.
