IscJinocohis, Aiisserer (Verh. z.-b. Wien, 1871, p. 184), repre- 

 sented by many species in tbe Mediterranean countries, differs 

 from the two preceding in having no tibial spurs on the 1st leg in 

 the male. Jt thus slands nearer to Miaschistopus, but may be 

 recognized by having all the tarsal scopulae divided ; the division in 

 Miascliistojiiis being restricted to the 4th leg.

In the type and other examples of this species the upper row 

 of notes on the mandible consists of 5 hairs, and the lower of 

 about 10 which gradually decrease m length posteriorly and project 

 internally away from the adjacent and spiniform setae. On the 

 maxilla there are upwards of 30 notes, forming a thick cluster, 

 those that lie nearest the suture being the largest, while inter- 

 nally and posteriorly they decrease in size and pass without inter- 

 ruption into the hairs of the oral fringe. 



The organ is present in the young, but less perfect in its 

 development. For example, in a specimen from East Loudon the 

 carapace of which measures but 5 mm. long, that of the adult 

 attaining to 25 mm., the bristles of the mandible constituting the 

 lower series have not become separated off from the adjacent 

 setae, though the upper series occupies the same position as in the 

 adult ; while on the maxilla only about a dozen of the notes are 

 distinguishable. At this stage the feathery pad on the upper 

 half of the outer surface of the mandible has not appeared ; but it 

 is fully formed and the organ complete in all its details in a half- 

 grown specimen from the same locality, v\ ith the carapace 12 mm. 

 long. 



This species seems to have an exceedingly wide range in Africa. 

 The Museum has examples from the following localities : — Port 

 Elizabeth (including the type and specimens presented by 

 J. M. Leslie) ; Kleinpoort, Eastern Karroo {Amia Howarih) ; East 

 London {H. A. Spencer) ; Osborn, Pondoland {T. W. Focock) ; Kei 

 Eoad {Cajn. Trcvehjan) \ Matabeleland {H. M. Beddiuf/ion) ; and 

 Sheik Husein in Somaliland {Donaldson Smith), as well as others 

 without special locality. 



The occurrence of this form so far to the north as Somaliland is 

 exceedingly remarkable. I have failed, however, to distmguish the 

 single female specimen from that locality from Ausserer's type by 

 any reliable character either of colour or structure. The two 

 examples from Pondoland differ from the type in having the legs 

 shorter as compared with the carapace : the carapace for example is 

 considerably longer than the tarsus and prolarsus of the 4th as well 

 as a little longer than the tibia, protarsus and tarsus of the 3rd 

 and at least equal to those of the 4th ; whereas in the type and other
