Carapace about as long as wide or a little longer ; its median length about equal to 

 that of the anterior^ five tergal plates of the opisthosoma ; its surface, like the dorsal

 median area of the first and second straight, of the third, fourth, fifth and sixth 

 becoming gradually but only slightly more and more recurved; the length of the 

 median area of the first plate about half its posterior width ; of the second a little less

 and gradually .narrower, the median length of the sixth being about one-half its 

 posterior width ; median length of the seventh exceeding that of the first and
