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 Stephanopsinse and 
Misumeninse : 
Sub-family Stephanopsinas. 
Genus Saccodomus. 
First pair of legs longer than second; 
Maxillce 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. 
First and second pairs equal ; 
Maxilla; 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 MisumeninEe. 
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 genus Saccodomus agree with — 
Sub-family Stephanopsinse. 
Sub-family Misumenina;. 
Labium (with some genera); 
Forehead not attenuated ; 
Front femur not bespined ; 
Anterior row of eyes not near 
together. 
Maxillae inclining inwards; 
Shape of labium ; 
Lower edge of falx smooth ; 
Tarsi without claw tufts ; 
Front row of eyes ; 
Hairs upon clypeus ; 
Skin bristly; 
Forehead square ; 
No spines on tarsi or metatarsi. 
It will be seen, from the above comparative tables, that the 
majority of points rests in favour of the sub-family Misurnenime, 
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 Tam worth, 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.
