belly, and particularly on the form and size of the black area which 

 it frequently exhibits. The male of our Var. a (with black belly), 

 Blackwall has described under the name of L. famelica. L. captam 

 Walck. is our Var. /3, distinguished by a triangular black spot on 

 the pale belly. C. Koch appears to have described this species under 

 two separate names, L. isabellina and L. famelica: the first appears 

 to me to represent a black-bellied specimen, in which the marking 

 on the abdomen was indistinct or faded (L. isabellina C. Koch is 

 by Simon loc. cit. , p. 83, referred to Tar. liguriensis, which is a 

 far larger spider than Koch's species): L. famelica C.Koch is, as also 

 L. vagabunda Luc, decidedly a variety of the same species, with the 

 under side of the abdomen pale- coloured. — L. tarentulina Sav. et Aud. 

 (Descr. de l'Egypte, 2 e Ed., XXII, p. 363, PI. IV, fig. 2), to which 

 Walckenaeb, in Ins. Apt. I, p. 305, refers L. radiata Latr., does not 

 belong to the species before us: it differs by the lateral bands on 

 the cephalothorax being coarsely indented on the upper border, etc., 

 and is more nearly related to the genuine Tarantulse, T. Apulioz 

 (Walck.), T. melanogaster (Latk.) etc., although it is considerably 

 smaller than they. 



(Pag. 509). 18. L. pinetorum [= Tarentula pinelorum Thor. 1856.] 

 Syn.: 1856. Tarentula pinetorum Thor., Bee. Grit. Aran., p. 58, 111. 



The marking on the back of the abdomen in the male T. pi- 

 netorum is very like that of T. andrenivora (L. barbipes Westr.) 

 cf, which however has a pale-coloured belly, and an entirely diffe- 

 rent form of the tooth under the bulbus genitalis. From males of 

 T. aculeata (Clerck), nob., or L. tceniata C. Koch, with the upper 

 part of the abdomen of a similar pattern, T. pinetorum cf can hardly 

 be distinguished by any thing else than its black belly, and by the 

 lamellar, transverse, inward-turned, almost triangular tooth under 

 the outer side of the bulbus being somewhat larger and on its ante- 

 rior side, along the base, provided with a projecting border or ledge, 

 which is absent in T. aculeata d\ This last mentioned spider is 

 often as large as T. pinetorum: I have a few male specimens of 

 T. aculeata, the cephalothorax of which is 5'/ 2 millim. long, while 

 in others it is not more than 4 millim. The male's cephalothorax 

 in T. pinetorum is as long as, or a trifle longer than, the patella + 

 tibia of the 4 th pair, its greatest breadth about % millim. more
