directed outwards, with its whole width greatly produced, broad and rather rounded at its hind extremity, 
and directed against the palpal organs; the digital joint is very small, oval, with its convex side directed 
inwards. The palpal organs are very simple, with a small, black, spiny, somewhat corkscrew-shaped 
process at their extremity. 
Falces moderate in length and strength, straight, vertical. 
Mawille straight, considerably inclined over the labium, and obliquely rounded at their outer extremity. 
Labium short, its height hardly more than half its breadth, rounded at the top; these parts are yellow slightly 
tinged with yellow-brown. 
Sternum broad-heart-shaped, the posterior point obtusely truncated ; colour yellow. 
Abdomen short-oval, projecting considerably over the base of the cephalothorax; of a pale dull yellowish hue, 
thinly clothed with hairs, and with a large, nearly round, tolerably well-defined black patch on the upper-- 
side rather behind the middle. The spinners are short, compact, and of a blackish-brown colour,

~FRONTINA, Keyserling. 
Frontina phenicea, sp. n. 
Adult male, length slightly over 1 line; adult female, a trifle larger. 
Cephalothorax deep rich shining black-brown. Legs and palpi similar in colour. 
Abdomen glossy, clothed thinly with slender pale bristles ; colour crimson. Spinners black-brown. 
Mawille, labium, and sternum similar in colour to the legs. In the female the area of the genital aperture is 
large, very convex, and of a deep black-brown hue. 
The legs are long, slender, subequal in length, 4, 1, 2, 3, furnished with hairs, and a slender spine on the 
genual and one also near the base of the tibial joint. 
The palpi of the male are rather short. The radial joint is very short and of peculiar form, produced both in 
front and behind, the hinder part much the shortest and broadest, roundly obtuse at its extremity; the 
anterior portion also broad and obtuse, but rather narrower at its extremity, which is strongly and abruptly 
hooked. ‘The digital joints are large. The palpal organs are highly developed, prominent and complex, 
with one of their processes produced beneath into a strongish, circularly-curved, prominent, tapering, 
black spine. 
The eyes are rather small, subequal, and form a large nearly semicircular figure whose convex side is directed 
forwards. The four centrals form a trapezoid, longer than broad ; those of the hind-central pair are of a 
pearly hue, oblong-oval in form, and much nearer together than each is to the hind-lateral eye on its 
side. The eyes of the posterior row are in a straight line. The height of the clypeus exceeds half that 
of the facial space, and from it (in the male), just below the fore-central pair of eyes, a curved spine 
turns upwards. 
Hab. GuateMALa, Antigua (Sto//). 
Closely allied to Frontina (Linyphia) coccinea, Hentz. The sexes resemble each other 
in all general characters. ‘The specimens described were forwarded to us by Mr. Sarg. 
TETRAGNATHA, Latreille. 
Tetragnatha pachygnathoides, sp. n. 
Adult male, length 24 lines. 
The whole of the anterior part of this spider is yellow; the legs with rather paler indistinct annulations. 
Cephalothorax of normal form. 
Eyes in the ordinary position. The four centrals form a square whose anterior side is rather the shortest. The 
two hind-centrals, with the fore-laterals, form a transverse straight line; those of each lateral pair are 
seated on a strongish oval tubercle, but not quite contiguous to each other; the fore-centrals are also 
seated on a strong tuberculiform prominence,
