Tlie second row of eves is halfway between the first and the 

 thirdj and the qnadrangie is equally wide in front and behind. 

 The thoracic part, while it does not slant backward for some 

 distance behind the dorsal eves, rounds off on the sides. 



We have two males and several females, sent to us from Trini- 

 dad, bv Mr. Broadwav. 



Dynamius finihriatus, sp. nov.

This handsome spider has a heavy fringe of black hairs along 

 the front sides of all the legs, especially heavy on those of the 

 second pair. The first and second legs are enlarged, and have 

 the tibia and the distal end of the patella, brightly iridescent. 

 The integument of the cephalothorax is iridescent, the cephalic 

 part being black and the thoracic brown. There are wide white 

 bands on the sides, and the upper surface was probably covered 

 with yellowish scales of which a few patches remain. Around 

 the eves are rinc;s of reddish hairs. The faice-s are brown,

slightly iridescent, vertical, and moderately stout, with little 

 white bristles on the front face. The abdomen seems to have 

 been covered with yellowish white scales. Under alcohol it ap- 

 pears whitish, v>dth a wide transverse brown band in front of the 

 middle, and two large brovai spots on the posterior part. There 

 :is a long fiat thoracic plate and the lirst rov/ of eyes is distinctly 

 •.curved. The quadrangle of the eyes is wider in front than be- 

 Ihind, and the second row is a little nearer the first than the third. 

 The fringes on the legs serve to distinguish this species. We 

 have two males from Chapoda, Brazil,, in the Smith collection.

Legs $> 1324; ? 3412; all rather slender. In the female the

We have a good many specimens of this species but all have 

 suffered more or less from rubbing. Under alcohol they show
