[June 5, with brown ; the caput is strongly marked, mottled, and suffused with deep yellow-brown; the thorax has a fine submarginal line, as well as some converging lines and other markings, of the same hue. The height of the clypeus is equal to half that of the facial space. On the caput are a few shortish bristly hairs. The eyes of the hind-central pair are much wider apart than each is from the lateral eye on its side ; the same proportionate separation is observable, though not to the same degree, in the eyes of the anterior row. The fore-centrals are the smallest of the eight. The legs are of a pale dull yellowish hue, with a few obscure blotches of white, and more or less marked and spotted with blackish brown. The falces are similar in colour to the cephalothorax, thinly mottled and marked with dark yellow-brown. The maxilla and labium are pale whitish yellow-brown. The sternum is similar to the falces in colour ; its central portion deep yellow-brown. The abdomen is thinly clothed with hairs and a few short bristles ; its colour is a dull whitish yellow tinged with brownish, somewhat speckled and marked with yellow-brown and deep black-brown; some of the deeper markings are lineate and oblique, others, towards the hinder part, are transverse ; a small elevation halfway between the fore extremity and the beginning of the hinder slope is marked with a somewhat curved, transverse, geminated spot, forming probably a characteristic central abdominal marking. The underside has a broad longitudinal central band suffused with sooty brown, deepest along its margins. An example of this curiously formed Spider was received from Mr. Mansel Weale, by whom it was found in Caffraria. It is evidently allied to Monastes, Luc.; but a consideration of its abnormally formed caput and some other characters have induced me to found a new genus upon it. List of Species described.
