III.— Some Crustacea of Natal, 



by the 



Rev. T. R. R. Stebbing, F.R.S., F.L.S., F.Z.S. 



With Plates I-Y. 



'"THE numerous specimens of Crustacea accumulated in the Durban 

 Museum by members of the staff, with the assiduous help of 

 Mr. Bell Marley, would have been more methodically treated by 

 dealing thoroughly first with one tribe and then with another. But 

 various conditions of the work, and the worker, have brought about 

 the offering, such as it is, of occasional notes rather than a formal 

 treatise. Of the twelve species discussed in the present contribution 

 only three claim to be new. 



Tribe OXYRRHYNCHA. 



Family ACANTHONYCHID^. 



Genus DEHAANIUS, McLeay. 

 See these Annals, vol. ii, pt. 2, p. 49; 1918. 



Dehaanius macleaii (Krauss). 



1843. Acanthonyx macleaii, Krauss, Die siidafrik. Crust., p. 47, pi. 



3, fig. 6. 

 1900. Dehaanius macleayii, Stebbing, Gilchrist's Marine Invest., 



vol. 1, p. 20. 

 1900. D. macleaii, Stebbing, Ann. S. Afr. Mus.. vol. vi, pt. 4, p. 288. 



In 1900 I suggested the probability that this species might be 

 synonymous with Dehaanius dentatus (Milne Edwards) and with D. 

 quadridentatus (Krauss). The latter form and the present have both 

 been sent me by Mr. H. W. Bell Marley from pools at Isipingo, Natal. 

 But while there are no intermediate forms, it would be rash to unite 

 them.. The specimen agreeing with D. macleaii (Krauss) is 6 mm,
