1879.] REV. O. P. CAMBRIDGE ON NEW ARANEIDEA. 293 



of Spiders made for me on the river Coanza(W. Africa) several years 

 ago by Mr. Henry Rogers, of Freshwater, Isle of Wight. I am not 

 aware of any described female Gasteracantha of which it may pos- 

 sibly be the male. It is not unlikely that the female may have the 

 usual six abdominal spines ; and it probably belongs to the group 

 Isacantha, Simon 1 . 



Genus Paraplectana, Capello. 



Paraplectana thorntoni. (Plate XXVII. fig. 24.) 



Eurysoma thorntoni, Blackw. Ann. & Mag. N. H. Nov. 1865, 

 p. 348. 



No figure has ever yet been published of this large and beautiful 

 Spider ; I have therefore great pleasure in being now able to give 

 one of it, taken from the type specimen from which Mr. Blackwall's 

 description was made. 



That description, in its exactness, leaves nothing to be desired ; it 

 need, therefore, only be added here, that the jet-black ground-colour 

 of the abdomen, with its somewhat raised, large and conspicuous 

 bright-yellow markings, and yellow cephalothorax, render it one of 

 the most striking and handsome known Spiders of this family. 



An immature example (also a female) was received from Mr. 

 Mansel Weale among the other Spiders collected by him in Caffraria.

1 Dr. Thorell writes to me, lately, that he has just received from New Guinea, 

 or the neighbouring islands, the males, " true pygmies," of Gasteracantha lepel- 

 letieri and G. crucigera, Bradley, descriptions of which I hope we shall soon 

 have from the pen of that able arachnologist. The only other known male of 

 Gasteracantha is that of G. parvula, Thor., from Singapore.
