Arachnida from the Island of Johanna. 43 



flattened in front and shelving behind ; abdomen subcylin- 

 drical, narrower behind than in front, with truncated anterior 

 margin ; relative size and position of eyes as in the preceding- 

 species, briefly expressed as follows — a c 6, a l=p I 1, i I £ ; 

 relative length of legs 1,3, 2, 4, but the three posterior pairs 

 differing very slightly in length ; cephalothorax and abdomen 

 together 7 millims. 



This species seems to be intermediate in character between 

 A. haptizatus of Rodriguez and A. muscivorus of Reunion and 

 Mauritius ; it is, however, unquestionably nearest to the 

 latter. 



5. Attus anjuanus, n. sp. (PI. I. fig. 4.) 



$ . Cephalothorax piceous (when dry of a golden bronzy 

 colour), crossed behind the middle by a Insinuated castaneous 

 belt, behind which the coloration is paler than on the caput ; 

 abdomen whity brown, with a longitudinal arched black stripe 

 on each side • anterior border black-speckled ; spinners black- 

 ish ; legs and palpi castaneous, clothed with white hairs ; 

 falces piceous ; legs below and pectoral shield fulvous ; venter 

 whitish. 



Cephalothorax rather elongated, inverted-bell-shaped, flat- 

 tened in front and obliquely arched from behind the posterior 

 oculiferous tubercles, the latter placed at anterior third ; abdo- 

 men ovate, with convex anterior margin, posterior margin 

 acuminate ; relative size of eyes, a c 6, a l=p I 1, « / -J- : rela- 

 tive length of legs 1, 3, 2, 4; cephalothorax and abdomen 

 together 8 millims. 



Apparently allied to A. africanus of Reunion. 



6. Spermophora comoroensis, n. sp. (PI. I. fig. 5.) 



Fulvous, with whitish abdomen ; falces below reddish cas- 

 taneous. 



Cephalothorax inverted-heart-shaped, posterior margins of 

 the caput indicated by a depressed V-shaped line, from which 

 a central depressed longitudinal line runs to the posterior 

 margin ; abdomen ovoid ; legs somewhat sparsely but regu- 

 larly covered with minute black granular dots ; tarsi clothed 

 with short setae ; palpi setose ; pectoral shield elongate scuti- 

 form ; eyes six in number, about equal in size, placed in pairs ; 

 the anterior pair placed in the centre of the anterior portion 

 of the caput, the lateral pairs at about the same distance from 

 the anterior pair as is covered by the two eyes themselves, and 

 placed obliquely ; male palpus with the fourth joint barrel- 

 shaped, much larger than the three preceding it, terminating 

 in a bulb-like joint fringed externally with stiff bristles, and
