Again, in Mr. Robert MacAndrew's Eeport * on the 

 MoUusca of the Gulf of Suez (republished 1885, with addi- 

 tions and corrections, by the Rev. Alfred H. Cooke fj of 

 Cambridge), 608 species are finally admitted as distinct, as 

 against Mr. MacAndrew's own estimate of 818. 



Here, again, is a remarkable consensus of figures. 



In 1870 Issel and Tapparone-Canefri monographed the 

 Strombidge, in 1875 the latter (Tapparone-Canefri) the 

 Muricidge, of the Red Sea; and C. F. Jickeli enumerated 45 

 Mitridse and 34 species of Conus from the same waters, of 

 which the most interesting are Mitra Hempnchu^ Issel, 

 Conus schech^ Jick., and Conns Jickeln^ VVeiiik. 



Dr. F. Jousseaume has of late years personally collected 

 on these shores, and has been successful in discovering many 

 new and some doubtful forms, to which he has given descrip- 

 tions. It might be wished by some that he would not attempt 

 so minute a subdivision of genera without sufficient cause, as 

 in Cyprcea, for instance. Not having seen any of the 

 following genera propounded by this author | in 1894 from 

 Aden and the Red Sea, I cannot pronounce upon them : — 

 Kyrina^ Extra^ Djeddilia, Stolida^ Agagus, Psammosphcerita. 

 The name Exti-a extra, given to a shell with some unusual 

 attribute of beauty, thus fatal to itself, should be disallowed 

 as offending nearly all the canons of the laws of nomenclature. 

 Stolida avalitensis, from Aden, apparently is a Stromhus, 

 Agagus agagiis, from the Gulf of Aden, is, by the description, 

 too imperfectly defined to be placed in any family, through 

 lack of a figure. Djeddilia djeddilia, another curious duplica- 

 tion, is also in the same unfortunate position. 



In 1888 the same author publislied a list of mollusks 

 collected by Dr. Faurot § in the same localities (Red Sea and 

 Gulf of Aden), 218 species in all. 



Signor G. Caramagna, in the same year (1888), published 

 a list II of South- Arabian species, mostly from Assab, with 

 ten new species described, mostly belonging to the Turbinidas 

 and Trochidee.
