reception, and by way of illustration the following tables are 

 submitted : — 



Points showing wherein the genus Saccodomus differs from 

 genera included in the sub-families Stephanopsinaj and 

 Misumeninse : 



Sub-family Stephanopsinse. 



First pair of legs longer than second; 



Maxillae parallel ; 



Forehead vertical ; 



Both rows of eyes equally recurved; 



Teeth on lower margin of falx ; 

 No row of hairs upon exterior mar- 

 gin of falx. 



Genus Saccodomus. 



First and second pairs equal ; 

 Maxillee slightly inclined inwards; 

 Forehead sloping; 

 Posterior row of eyes less recurved 



than anterior row ; 

 Lower margin of falx smooth ; 

 Hairs present upon exterior margin 



of falx. 



Sub-family Misumeninse. 



Genus Saccodomus. 



Second pair of legs longest ; 



Forehead square, vertical ; 



Both rows of eyes equally recurved. 



First and second pairs equal ; 

 Forehead square, sloping ; 

 Posterior row of eyes less recurved 

 than anterior row. 



Points in which the arenus Saccodomus agree with- 



It will be seen, from the above comparative tables, that the 

 majority of points rests in favour of the sub-family Misumeninre, 

 in which for the present it is placed ; and again, if the reader will 

 refer to pi. xxx., figs. 2 and 26, he will note, so far as the abdomen 

 is concerned, a striking resemblance in contour to those species 

 forming the sub-family Stephanopsime. 



Until quite recently our collection contained only one specimen 

 of this remarkable spider, and this fact made me dubious about 

 describing it. Fortunately, however, an esteemed correspondent, 

 Mr. D. A. Porter, of Tamworth, to whom reference has already 

 been made, forwarded additional specimens to the Trustees, by 

 the aid of which supplementary material, I feel I am now justified 

 not only in describing the species, but also in founding a new 

 genus for its reception.
