2223 ARANEIDEA. 
scoop-shaped termination, on the inner side of which is a slender, bent, diaphanous, semi-corneous 
process. 
Hab. Mexico, Venta de Zopilote in Guerrero (H. H. Smith). 
HYPOGNATHA, Guérin. 
(Hypognatha, Guér., 1839; Calydna, Cambr., 1874; Mutina, id., 1881.) 
Hypognatha nasuta, sp. n. 
Adult male, length slightly over 1 line to rather less than 14 line; adult female rather more than 14 line. 
Very similar in general form and appearance to H. (Mutina) furcifera, Cambr., though it has some remarkable 
points of difference. 
Cephalothorax of normal general form; the lower margin of the clypeus is greatly produced in a kind of shelf 
or platform shape, the exterior corners still more projecting both forwards and sideways, and from the 
middle of the fore edge of the clypeus is a prominent, somewhat cylindric, slightly tapering, obtusely ended 
corneous process, bent downwards and extremely nose-like (in H. furcifera a still longer process, bifid at its 
extremity, springs from the upper part of the clypeus immediately below the central eyes). Colour of the 
cephalothorax, as well as of the legs, palpi, falces, maxille, labium, and sternum, yellow-brown. 
Eyes on black spots, four forming very nearly a square close to the middle of the fore margin of the caput; the 
anterior pair largest, those of the lateral pairs are minute, contiguous, and placed immediately below the 
extremity of the produced corners of the clypeus. 
Faices long, strong, slightly divergent, but nearly straight. 
Pailpi short ; digital joint and palpal organs of large size and development, the latter prominent and complex. 
Maxille, labium, and sternum normal. The pedicle connecting the cephalothorax and abdomen appears to be 
joined or articulated to the hinder extremity of the sternum. This peculiarity is described and figured in 
the delineation of H. prospiciens, Cambr. [Ann. & Mag. Nat. Hist. (4) xiv. t. 17. fig. 3d]. From its 
presence in the three species probably it is of generic value. 
Abdomen large, somewhat subtriangular heart-shaped, projecting greatly over the thorax. Integument 
coriaceous, rugulose below, of a pale yellow-brown hue, marked above in a kind of reticulate way with 
paler lines, mapping out the surface in a regular sort of tortoise-shell fashion ; four round red-brown spots 
form a large square, or very nearly a square, on the middle of the upperside. In another example, of a 
generally darker hue, the colour of the abdomen is deep brown, nearly black, with a large cream-yellow, 
well-defined, somewhat quadrate patch at each anterior fore corner, and in the medial line of the hinder 
part are 2-3 small yellow spots in a longitudinal series. 
The female is a little larger than the male, but resembles it in the general colour and character of the markings, 
though the peculiar development of the clypeus is absent; probably a series of both sexes would show 
that there is considerable variation both in the colours and distinctness of pattern. Genital process of 
characteristic form, but not long nor conspicuous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Mr. Smith has the following note on this spider :—‘ Found in open wet ground near 
a highland stream, in a rather coarse slanting geometrical web, five or six inches in 
diameter, supported by lines 5 feet long to trees 10 feet apart, and about 8 feet above 
the ground, the spider in the centre.” 
SPERMOPHORA, Hentz. 
Spermophora placens, sp. n. 
Adult female, length rather less than 1 line. 
Cephalothorax almost circular, not very convex above, as broad as long; clypeus extensive, much produced at
