254 AMERICAN SPIDERS AND THEIR SPINNINGWORK, 
irregular spots in the middle. Spinnerets and gills dark brown; epigynum is dark brown, 
chitinous, with a cluster of yellowish hair on the atriolum, which is orange yellow; it is 
without a scapus, but has four platelike cells, two in front and two others at the sides. 
Disrriputton: I haye specimens from islands of the Carribean Sea, received from Mr. 
C. H. Townsend; Dr. Marx has examples from Louisiana and Texas; Koch described from 
a Brazilian specimen. The species is therefore probably limited in the United States to our 
Gulf Coast, and does not appear to be abundantly distributed therein. It no doubt abounds 
throughout the Northern States of South America.

Fremane: Total length, 27 mm.; abdomen, 19 mm. long, 6 mm. wide at the base, 3.5 
to 4 mm. at the apex, 4 mm. in the middle; cephalothorax, 8 mm, long, 6 mm. wide across 
the corselet, 4 mm. at the face. Baron Walckenaer (Ins. Apt., II., page 98), in his descrip- 
tion of Nephila (Epeira) fuscipes Kocu, makes that species identical with Nephila maculata 
of Leach and Fabricius. In this he errs, for the two species are very different, as one may 
easily see by comparing Walckenaer’s descriptions and the figure of Koch with Leach’s 
excellent figure. The drawings of N. maculata on Plate XXIII. were from an adult female ; 
but after it had been completed I received from Dr. Marx several much larger specimens, 
one of which has a body length of an inch and three-quarters, and measures 7.5 inches 
(nearly two decimetres) from the tip of leg-I to the tip of leg-IV; leg-I is four inches 
long. These creatures strongly suggest the vigorous African and other tropical species of 
this beautiful genus. 
CrrHatotHorAx: Cordate; corselet rounded at the edges, depressed in the centre at 
the fosse, which is a deep lateral slit; rather flattened upon the top; the corselet grooves 
indistinct or obliterated; the cephalic suture sufficiently distinct; the body color brown to 
brownish yellow, covered thickly with golden yellow pubescence. The caput is narrowed at 
the base, on which, a little in front of the fosse, are two low conical processes on either 
side of the median line; beyond them are two depressions in the surface of the caput, 
which is brown, glossy, and provided less abundantly than the corselet with pubescence. 
The head is raised above the corselet, well arched to the face; sternum shield shape, about 
as wide as long; with sternal cones, one especially prominent in front of the labium, giving 
the centre of the sternum an elevated appearance; glossy brown; indented at the edges; 
sparsely pubescent (though the hairs may be obliterated by the alcohol); the apex some- 
what blunted or T-shaped, and bearing upon either side a slight conical eminence; the 
labium is long, two-thirds the length of the maxille, rectangular at the base, which is 
thicker than the obtusely triangular tip; the maxille are longer than wide, narrowed at 
the base, curved upon the inner edges next the labium; ovate at the tips, where the width 
is about three-fifths the length; the color of maxilla and Jabium dark brown. 
Eyes: Ocular quad on a rounded eminence more decided in front, leaving the rear 
eyes situated at the base thereof; the quad is decidedly narrower in front than behind, but 
the posterior width is equal to the length; MF slightly larger than MR, separated by about 
1.5 to 2 diameters; MR separated 2 to 2.5; side eyes upon prominent tubercles; SF but 
little larger than SR, separated by something more than a radius; all the eyes of the group 
amber yellow; SF separated from MF by 1.5 the area of the latter, or at least two times 
or more the intervening space of the same; the clypeus is rather high, from the margin to 
MF being about three diameters of the latter; the front row very slightly recurved, almost 
aligned; the longer rear row is procurved. 
Leas: In the specimen in hand the legs are much broken and the color greatly 
modified by the alcohol. So far as reconstruction permits, the order shows 1, 2, 4, 3; the 
color brown, and, judging by the pits, apparently well armed with strong spines and thickly
