This abundant and widely-spread species has long been known under the name 
Acrosoma armatum, C. L. Koch, a form which may or may not be identical with it. 
In any case, the specific name armatum is preoccupied by Olivier (sec. Simon, Hist. 
Nat. Araign. édit. 2, 1. p. 852, fig. 911).

The type-specimen of K. cornigera is mature, but not fully chitinised and pigmented ; 
it is identical with A. calearatum. 
9. Micrathena vitiosa. (Tab. L. figg. 11, lla, 3.)

Type, d, in coll. Godman & Salvin. Total length 4°5 millim. 
General characters as in If. brevipes, except that femora i. and ii. and tibia ii. are spined. Femora i. and ii. 
with several stout apical spines on each side. Tibia ii. with a series of five long spines beneath. 
Abdomen black, with the vestigia of three pairs of spines, enlarged apically, having a white transverse 
median spot. 
Tarsus of palpal bulb developed into an immense concave, quadrate, closely and very finely granulose sclerite, 
which forms the “ tarsal hook” or clasper, see Plate.

10. Micrathena granulata, sp.n. (Tab. L. figg. 12, 12a, ¢.) 
Type, d, in coll. Godman & Salvin. Total length 4 millim. 
Carapace elongate-oval, with central and three lateral fovee, and in general respects very similar to 
M., parallela. 
Legs not spinous, except femur 1., which is incrassate, armed apically on the anterior side with five or six long 
stout clasping spines. ‘ibie i. and ii. and patelle i—iv. also bear spines. Coxai. without hook, and 
femur ii. without groove. Coxee iv. closely situated, and leg iii. as in MW. brevipes. Tarsal hook of sheath 
of the palpus characteristic, broad, oblong, concave, apically recurved, set with numerous minute teeth, 
its concave area also studded with minute dentiform granules. 
Carapace dull orange, legs paler; abdomen dull yellow, anterior and posterior margins dusky, with a central 
dorsal and three lateral white spots.
