South African Cnisfncca. 



On p. 30 in the reference to " Liiiupdrls, White, 1847," ^^^ 

 generic name should be Linupnnts. Attention was called to 

 this by Dr. Woodward in the Geological Magazine, vol. 7, 

 p. 394, where, however, the error is not traced back to its 

 source in the report on the Challenger Macrura. 



P. 33. To the list of those who have used Astacus as the 

 generic name of the lobster may be added W^stwood, in the 

 Entomologist's Text-book, p. loi, 1836. 



P. 37. In the last line the epithet "perplexing" is quite in- 

 appropriate to the statement quoted from Huxley, and the 

 comment upon it with which the paragraph ends on p. 38 is 

 quite beside the purpose. The mistake arose from a confusion 

 of the eighth somite of the body with what is sometimes called 

 the eighth thoracic somite. As my friend Dr. W. T. Caiman 

 promptly pointed out, there is only an infinitesimal difference 

 between Huxley's observation that the second maxilliped in the 

 lobster is without an arthrobranchia, and the explanation by 

 Boas that this arthrobranchia is reduced to a pimple. 



P. 4Q. In the svnonymy of AEgcoii should have been in- 

 cluded a reference to Faxon's Stalk-eyed Crustacea of the 

 Albatross, Mem. Mus. Comp. Z06I. Harvard, vol. 18, 1895, 

 where an important footnote to p. 134 discusses that genus 

 (with the changed spelling AEgin'oi!},:ind expresses the opinion 

 that Bate's Pontocaris is to be identified with it. 



Pp. 54, 55. Some modifications in the description of the 

 first maxillae and maxillipeds of Paridoica ungiihiin are supplied 

 in the account now given of the family Idotciiiac. 



P. 60. It should have been mentioned that the specimen of 

 SpJivrion laevigatmu was taken from a Gcnyptcnis cd pen sis, 

 locally known as the " King-Klipfish."
