220. Mactra decora, Deshayes. 



Hab. '! {Deshayes and Reeve); New S;)iUh Wales (W^ein- 



kauff) ; Assab and Berbera {Caramagna) ; Merjrui {Martens). 



With this species I have no hesitation in uniting M. jickelii of 

 Weinivauff from Massowa on the coast of Abyssinia. 



221. Mactra fauroti, Jousseaume. 



M. fauroti, Jousseaume, Mem. Soc. Zool. France, 1888, vol. i. 

 p. 2UU. 



Hab. Aden (Jousseaume). 



The shell fi-^nred by Weinkauff (Conch.-Cab. Mactra, pi. 19. 

 figs. 5, fi, 7) as M. pulckra. Gray, evidently belongs to the present 

 species. 



222. Mactra (Meropk) ^gyptiaca, Chemnitz. 

 Hab. Red Sea {Chemnitz) ; Ceylon (Reeve). 



223. Cardium rugosum, Lamarck. 



Hab. Madagascar, Red Sea, Eist Africa, Ceylon, North Australia, 

 Philippines, &c. 



224. Cardium rubiccndum, Reeve. 

 Hab. Zanzibar. 



225. Cardium setosum, Redfield. 

 Hab. China, Philippines. 



226. Cardium australis, Sowerby. 



Hab. South Africa, Mauritius, China, Australia; Assab? {Cara- 

 magna).

Hab. Ceylon: Adea {Jousseau7ne). 



Both in the ' Conchologia Iconica ' and in the * Conchylien- 

 Cabinet,' Sowerby is given as the author of this species. This is 

 incorrect, as part 32 of Sowerby's ' Genera of Recent and Fossil 

 Shells,' which contained the account of Solen, did not appear until 

 1829, wliereas this species had already (1825) been figured by Wood 

 under the name of Solen truncatus. Sowerby's ' Genera ' was not 

 published in 1820-25 as appears on the titlepage, for reviews of 

 Numbers 29, 30, and 31 appeared in the 'Zoological Jouriial,' 1828, 

 vol. iii. p. 284, and in Loudon's ' Magazine of Natural History,' 

 vol. i. (1828) p. 56, vol. ii. (1829) p. 50. 1 am not aware when 

 the work was completed, but I dare say it could be ascertained by 

 searching for reviews of it. Unfortunately, the original covers of the 

 Numbers were only dated in a few instances ; for example. Number 

 xxxiii. is dated 1st March, 1831, Number xxxv. 30th April, 1831. 

 In the text relating to Purpura, j)ublished in Part 42, reference is 

 made to Gray's genus Pollia, described in the ' Zoology of Beechey's
