A detailed description of the new species is unnecessary since the differences that 

 obtain between it and L. ftmbriatus (Dol.) may be briefly expressed in tabular form 

 as follows. 



a. Carapace with the posterior cephalic angle widely rounded and strongly obtuse, 

 the upper surface of the cephalic portion much less strongly elevated posteriorly, the 

 whole carapace being longer as compared with its height ; the height from posterior 

 eye to a point between the coxae of 2nd and 3rd legs about equal to the length 

 of the tibia of the 1st leg and less than length of tibia of 4th .Jimbriatus (Dol.). 



b. Carapace with posterior cephalic angle nearly square, only a little obtuse, the 

 upper surface of the cephalic portion being much more strongly raised behind ; the 

 whole carapace shorter as compared with its height ; the height along a line taken 

 through posterior eye to a point between the 2nd and 3rd coxae exceeding the length 

 of the tibia of 1st leg and about equal to that of tibia of 4th leg alticeps, sp. n. 



Measurements in millimetres of L. alticeps. Total length 7 - 5 ; length of carapace 

 from posterior border to anterior eye 3"8 ; height from posterior border to summit of 

 head 33 ; vertical height from posterior eye 2 - 8 ; length of legs (from base of femur), 

 1st 11, 2nd 10, 3rd 9, 4th 13 - 5 (patella and tibia of 4th 4 5 ; tarsus and protarsus 

 5 - 5 ; patella and tibia of 1st 4). 



Loc. Rubiana, New Georgia (Solomon Islands). 



For comparison with the single adult female of L. alticeps obtained by Mr Willey, 

 I have in my hands a single adult female identified by Dr Thorell as L. jimbriatus, 

 Dol., which was collected by Sig. Beccari in Sumatra. According to Thorell L. Jimbriatus 

 ranges from Sumatra through Amboina and Papua to Cape York. For descriptions 

 of the species reference may be made to : Doleschall, Nat. Soc. Sci. Indo-Neer- 

 land, 1859, p. 22, pi. v. fig. 8; Thorell, Ann. Mus. Genova, xm. p. 269, etc., 1878, 

 and id. op. ext. xxxi. p. 352, 1892. 



L. labiatus, Thorell, from Burma and Java, has apparently the same form of 

 carapace in the female as L. Jimbriatus. 



Genus. Zenodorus, Peckham.

 Zenodorus, Peckham, Tr. Wisconsin Acad. vi. p. 297, 1885. 



Zenodorus variatus, sp. n. 



Carapace black, with a paler transversely arched area behind the posterior eyes ; 

 a patch of golden metallic hairs behind these eyes and more of the same colour on 

 the areas between the eyes ; a conspicuous marginal band of white hairs on the 

 posterior half of the sides of the carapace ; mandibles, maxillae and labium black, 

 palpi yellow with tarsus blackish ; legs of 1st and 2nd pairs reddish brown, with
