Acanthodon abrahami (Hewitt). 



Gorgyrella abrahami Hewitt, Records, Albany Museum, vol. ii, 



p. 473, 1913. 



I now prefer to place this species under the genus 

 Acanthodon, although formerly I doubtfully referred it to 

 Gorgyrella. It is probably closely related to A. ochreo- 

 lum Poc, of which only the male is known. The male of 

 abrahami seems to differ from that of ochreolum in the 

 closer approximation of the frontal eyes and in the less 

 strongly bent first metatarsus, but until more Jansenville 

 material is available for comparison the specific distinction of 

 abrahami should be held somewhat doubtful. Two adult 

 males of abrahami were taken by Mr. F. Cruden at 

 Alicedale on February 15th, 1914, and I here give a des- 

 cription of the sex. 



Frontal eyes quite separated, about one-third of a diameter, 

 or slightly less, apart ; the quadrangle formed by the frontal 

 and anterior median eyes wider behind, the medians large, 

 aboiit three-fifths to three-quarters of a diameter apart ; hind 

 margins of posterior row about in a straight line, the medians 

 two to two and a half diameters apart and a diameter or 

 slightly more distant from the laterals.
