first row straight ; middle about twice lateral ; quadrangle nearly 

 twice as wide as long and plainly wider behind. In ahnormis 

 ? the first row is bent downward, the eyes are small, the middle 

 being less than twice the lateral; quadrangle one-third wider 

 than long, and very slightly wider behind. In hitaeniatus ? 

 the first row is bent downward; middle eyes are twice lateral, 

 and separated from each other; lateral separated from middle 

 by nearly their own diameter; second row twice as far from 

 third as from first ; quadrangle about twice as wide as long, and 

 a little wider behind.

In this species the anterior eyes are rather large, and form a 

 straight row, the middle ones being nearly twice as large as the 

 lateral, and more separated from them than from each other. 

 The quadrangle of the eyes is nearly twice as wide as long, and 

 is very slightly wider behind. 



Under alcohol the cephalothorax is reddish with a dark eye- 

 region. The abdomen is pale brown with a white region down 

 the middle, which is covered with a network of brown lines, and 

 has, on the front part, a brown cross. On the sides of this pale 

 region, behind the middle, are two pairs of dark spots. The 

 legs are brovvai, the femoral joints being darkest. The palpi 

 are pale brown, long, and delicate. Our specimens are badly 

 rubbed, but when dry they still shew a few Jiairs, which 

 are iridescent on the eye-region and on the, sides of the upper 

 surface of t]ie abdomen, and white on the thoracic region and 

 on the lov/er sides and middle of the abdomen. The clypeus is 

 edged with vrhite. The f alces are brown in color and are stout, 

 rounded, obliquely directed forward, and divergent, with a long 

 fang.
