1/3. Paeabuthus capensis var. frenchi, nov. 



A number of specimens, apparently differing from capensis solely 

 in the shape of the shagreened area on the second caudal segment, 

 represents a local variety of capensis, inhabiting an area to the 

 north-east of that in which the principal form has hitherto been 

 found. 



The shagreened area of the second segment forms a short, oval, and 

 often rather deep depression, about If times as long as wide, and 

 occupying slightly more than half the upper surface. At the hind edge 

 of the upper surface a tiny shagreened area occurs in some specimens, 

 and in one case this is almost connected with the anterior area by a 

 few isolated granules scattered along the median line. Movable finger 

 with 13-14 anterior flanking teeth, the main rows as in capensis. 



{a) Types, 1 $■ and 4 ? (all adult) from Graaft" Eeinet {Geo. 

 French) (Eeg. No. 5207), and 1 juv. from the same locaHty (C L. 

 Leipoldt) ; number of pectinal teeth in $ 32-35, in $ 40 ; length of 

 largest ? 70, of $ 70. 



[h) 1 S and 1 J from Burghersdorp, presented by Dr. Schonland 

 of the Albany Museum, in which are a number of other specimens 

 from the same locality. These agree with the specimens from Graaff 

 Eeinet, except that I did not notice the tiny shagreened area near the 

 hind edge of second caudal segment. Length of J 77, of <? 60 ; 

 number of pect. teeth in ? 31-33, in S' 36. 



This variety was first collected by Mr. French, after whom it 

 has been named. 



2. Paeabuthus calvus Pure. 



1898. P. c, Purcell, Ann. S. A. Mus., v. 1, p. 28, pi. iv., fig. 7. S- . 



Besides the typical 3" we have a ? specimen from Clanwilliam 

 Div., which differs in being much more granular and in having a 

 narrower tail. This may perhaps be a different species. 



In the type the upper surface of the first caudal segment is wider 

 than long, but the shagreened area is narrower than in capensis and 

 only slightly widened in its anterior portion, which is only f as wide 

 as the upper surface of the segment. In the second segment the length 

 of the upper surface is equal to its width and the shagreened area is 

 parallel-sided, except for a slight posterior constriction, and a little 

 more than three times as long as wide. The movable finger has 14 

 anterior flanking teeth and the main rows in the middle third of the 

 finger are composed of 7-9 teeth. 



The following are some supplementary measurements, omitted in
