segments much wider than long. Tibiae, protarsi, and tarsi of 

 palpi and anterior legs thickly banded laterally with short spines, 

 but almost entirely without inferior spines ; tibia of 4th not 

 spined externally ; claws with a large basal tooth and one or 

 more smaller. 



Type, L. fossoria. 



Most nearly related to Cyrtocarenum of the Mediterranean basin, 

 but differing in the more compact setting of its eyes, the high 

 tubercle, unarmed labium, difPerent development of sternal sigilla, 

 and thicker spine-armature of palpi and anterior legs. 



This new genus is in all probability identical with Acattyma of 

 Simon, which is totally distinct from Acattyma of L. Koch. The 

 latter, as Koch's diagnosis clearly shows, is closely related to 

 Brachyboth^ium, and belongs to a different family from the species 

 referred by Simon to the genus Acattyma. 



The true Acattyma from Japan has the fovea not transverse but 

 forming a longitudinal impression ; the posterior spinners as 

 long as the protarsus of the 4th leg, Avith the third segment 

 equalling the length of the first and second taken together ; the 

 sternum with 3 marginal impressions on each side, the maxillae 

 untoothed and the mandibles " hoch empoi'gewolbt '"' at the base, 

 and armed with rastellum — characters which show its atfmity with 

 the two North -American genera Bracliyhothrium and Ati/poides 

 (see L. Koch, Verb. z.-b. Wien, 1876, p. 760). 



Latouchia eossohia, sp. n. (Plate XXI. figs. 2, 2 «.) 



Colour : carapace and mandibles nearly black ; legs and sternum 

 deep blackish brown ; abdomen blackish grey. Carapace as long 

 as patella ; tibia and protarsus of 1st leg almost as long as tibia, 

 protarsus, and tarsus of 4th. 2nd leg with 1 median inferior 

 apical spine ; patella, tibia, protarsus, and tarsus of 3rd spined 

 externally (in front) and internally, the internal spines on the 

 patella reduced to 2 near the top of the segment, protarsus with 

 3 inferior spines whereof 2 are at the base ; patella of 4th with 

 a short band of spines in its basal half externally, its tibia armed 

 with setiform spines below, its protarsus with a pair of inferior 

 apical spines, as well as others. 



Measurements in millimetres. — Total length 20 ; carapace 8 ; 

 1st leg 15, 4th leg 19.

Latouchia swinhoei, sp. n. (Plate XXI. figs. 3, 3 a.) 



S . Paler than the female of L. fossoria ; carapace and legs 

 reddish brown, femora of palp and of 1st and 2iid legs blacker. 



Carapace coriaceous, lower than in the $ of L. fossoria, a shallow 

 horseshoe-shaped depression behind the fovea and following its 

 curvature. Ocular tubercle lower ; anterior median eyes about a 

 diameter apart, smaller than the laterals, their centres about on a 

 level with the hinder edge of the laterals, hence the anterior line 

 is very distinctly procurved.
