304 Annals oj the South African Museum. 



Humphrey, 1797, but Trapezia and Trapezium are not the 

 same, as subsequently recognised by Miss Eathbun. 

 1898. Trapezia, Alcock, J. A. S. B., vol. Ixvii., pp. 76, 217. 



TRAPEZIA CYMODOCE (Herbst). 



1801. Cancer cymodoce, Herbst, Krabben und Krebse, vol. iii., pt. 2, 



p. 22, pi. 51, tig. 5. 

 1826. Trapezia c., Audouin, Crust. Egypte, p. 85, pi. 5, fig. 2 



(Savigny). 



1838. ? Grapsillus dentatus, M c Leay, Annulosa of S. Africa, p. 67, pi. 3. 

 1843. Trapezia ferruginea, Krauss, Siidafrik. Crust., p. 35. 



Krauss identifies M c Leay's species both with Latreille's 

 T. f. and with Audouin's T. c., and Miers, Challenger 

 Brachyura, p. 165, considers these identifications as perhaps 

 correct. 



1898. T. cymodoce, Alcock, J. A. S. B., vol. Ixvii., p. 219. 

 Alcock leaves unnoticed M c Leay's G. dentatus. 



TRAPEZIA FERRUGINEA, Latreille. 



1825. Trapezia ferruginea, Latreille, Encycl. Meth., vol. x., p. 695. 

 1838. Grapsillus subinteger, M c Leay, Annulosa of S. Africa, p. 67. 



Except referring it to Trapezia, Krauss expresses no opinion 

 on this species. 

 1886. Trapezia coerulea, Miers, Challenger Brachyura, p. 165. 



Miers doubtfully identifies M c Leay's species with the earlier 

 T. coerulea, described by Eiippell. 

 1898. T. ferruginea, Alcock, J. A. S. B., vol. Ixvii., p. 220. 



Alcock distinguishes this species, to which he refers G. sub- 

 integer, from T. cymodoce (Herbst), with which he unites 

 T. ccendca, of Heller and presumably of Eiippell. 



TRAPEZIA MACULATA (MLeay). 



1838. Grapsillus maculatus, M c Leay, Annulosa of S. Africa, p. 67. 

 1843. Trapezia rufopunctata, Krauss, Siidafrik. Crust., p. 36. 



Krauss only gives this identification of M c Leay's species 

 with that of Herbst as probable. 

 1886. T. r., Miers, Challenger Brachyura, p. 165. 

 1898. T. maculata, Alcock, J. A. S. B., vol. Ixvii., p. 221. 

 1907. T. m., Stimpson, Smithson. Misc. Coll., vol. xlix., p. 73, with 

 " Trapezia cymodoce maculata (M c Leay) " in footnote by 

 Eathbun.
