that the reference to Fabricius is unfortuiKiteiy printed as p. 450 

 instead of 460- Fabricius hiniseli has a species Cancer spinifrons, 

 which was instituted by Herbst in 1785, Krabben und Krabben^ 

 vol. I, pt. 6, p- 185, pi. II, fig. 65. This species has nothing; 

 whatever to do with Leaches Homola spinifrons, but for those who 

 may wish to verify this by the original authorities it should be 

 mentioned that Fabricius twice gives a misleading reference to 

 Herbs-t. In the Ent. Syst,., vol. 2, p. 455, he refers to " Cancer 

 spinifrons, Herbst. Cancr. tab. g. tig 58.," and in the Supple- 

 mentum he repeats this reference after one to his own work, as 

 though he himself were the author of the species- 



The South African specimen has the carapace ornamented as 

 figured by Milne-Edwards and described by Heller, and likewise 

 in agreement with the account given by Alcock of his Homola 

 andamanica- There are 13 spines between the short, slightly 

 depressed bifid rostrum and the cervical groove, and down each 

 side there is a row, beginning with a large tooth-like spine, 

 followed by a smaller one, ,and then by diminishing denticles to 

 the number of a dozen. The epistome has a central upturned 

 spine. The fourth joint of the third maxilliped being abruptly 

 narrowed ii> the distal half, looks as if a piece had been cut out 

 of its outer margin. The fourth joinlt in the four pairs of ambula- 

 tory legs is setose or spinulose on the inner margin, but seems 

 devoid of the tooth spines which are characteristic of H. ondot-' 

 manic a.
