MONOGRAPH OF THE ATLANTIDAE. 



to each other, and crossing the lines of growth, not to 

 be confounded with the undulating spiral sculpture at the 

 beginning of the last whorl. In fig. 27 they are not 

 figured. 



A specimen, figured ') by Vayssiere under the name ot 

 yyA. indinata' (fig. 91), most likely belongs to A, fuscay 

 chiefly on account of the »nombreuses lignes longitudinales 

 paralleles, constituees par une multitude de petites ponc- 

 tuations." No mention is made, however, of the much 

 coarser sculpture on the spire, which would certainly 

 have been observed, if present. 



Group of Atlanta inclinata. 



It contains two species : 



11. Atlanta inclinata Souleyet. 



12. Atlanta gihhosa Souleyet. 



These species are certainly not nearly related, and I have 

 enclosed them in one group only for the sake of convenience, 

 as, though mutually very clearly distinct, they are separated 

 off from the other species by their large, conical spire, 

 which is always reflexed on the last whorl, either forward 

 or backward. 



Species 11. Atlanta incliviata Souleyet. 

 1852. Atlanta inclinata Souleyet, non Vayssiere.

Animals: 



Red Sea, January '06, 1 sp., Buiteridijk.

Indian Ocean, April '06, 1 sp., „ 



This beautiful species is easily recognisable by the 

 following characters: 1°. the large spire forms a short

 (see p. 21).
