enabled to prove that fish lived at depths of 500 and 550 fa- 

 thoms — and, further, to arrive at some really important conclu- 

 sions regarding the constitution of the gases contained in their 

 swimming-bladders when subsisting under the conditions there 

 present. 



Dr. Wright has, moreover, to inform the scientific public on 

 what basis (when referring to my starfish-sounding at 1260 

 fathoms) he would have us believe that the " dredge " is alone 

 capable of affording " indications of animals higher than the 

 Rhizopods living at those depths " (loc. cit.), unless when, by 

 accident, that instrument happens to bring one of these " higher 

 animals" to the surface. 



Surely, if my discovery was an accident, the discovery of 

 Dr. Wright's shark was " an accident of an accident." 

 I remain, 



Gentlemen, 



Very faithfully, yours,

XIII. — Descriptions and Sketches of some neio Species of 

 Araneidea, ivith Characters of a new Genus. By the Rev. 

 O. P. Cambridge, M.A. 



[Plates IV., V., VI.] 

 Genus Stokena (Walck.). 



This genus was founded in 1805 by Baron Walckenaer 

 (Tableau des Araneides, p. 83, pi. 6. figs. 55, 56) upon a single 

 spider received from New South Wales. Five species from 

 the same region have lately come under my own eye ; and of 

 these, descriptions and sketches of characteristic portions of 

 structure are given below. 



Storena variegata. Storena australiensis. 



scintillans. maculata. 



Bradleyi. 



The last two of these I had at first described as constituting a 

 new genus ; afterwards the first two species came under my 

 notice, and in them I recognized at once the exact type of 

 Walckenaer's description ; between these and the last two no 

 generic distinction could be discovered, though each two were 

 the types of a distinct group within the genus; lastly, S. 

 Bradleyi came before me, and puzzled me much : incapable of 

 generic separation from S. australiensis and S. maculata, 

 except in a modified relative position of the eyes, yet by that
