^54 Mr. E. A. SmitK on Species ofBullidse. 



Cylichna (Sao) Pellyi. B.M. 



C. testa pyriformi, basim versus duplo latiore quam ad verticem, 

 alba, basi transversim distanter striata ; vertex umbilicatus, ex- 

 trinsecus lira (quae striis longitudinalibus curvatis semsim evanes- 

 centibus decussata est) circumcinctus ; apertura superne angusta, 

 super verticem producta, inferius valde dilatata ; columella bre- 

 vis, incrassata ; umbilici regie perforata. 



Long. 4 mill., diam. maj. 2. 



Hah. Persian Gulf {Col Pelly). 



This species is rather like C. nitida, A. Ad., in form ; but it 

 is considerably larger, and proportionally narrower towards 

 the upper end. 



Messrs. H. & A. Adams, in their ' Genera of Recent Mol- 

 lusca,' vol. ii. p. 21, give the following characters to /Sao, which 

 they place as a subgenus of Atys : — " 8hell jpyriform^ itmhili- 

 cated ; apex not perforated.'''' 



Of these characters the first two certainly apply better to 

 some of the species of the genus Cylichna than to those of 

 Atys^ and the third is a false one ; for in the descriptions of 

 the species characterized by A.Adams, he mentions the vertex 

 as being " subumbilicata " or " profunde perforata :" there- 

 fo-re I think Sao should be removed from Atys^ and be placed 

 as a subgenus of Cylichna^ from which it differs chiefly in 

 being pyriform. 



Tornatina liratispira. B.M. 



T. testa cylindracea, superius parum latiore quam basi, alba, nitida, 

 incrementi lineis curvatis striata ; anfract. 5, superius acute mar- 

 ginati, primus tubereularis ; spira brevissima, turrita, sutura late 

 canaliculata, medio lira filosa divisa ; apertura angusta, basi sen- 

 sim dilatata ; columella spiraliter uniplicata. 



Long. 6 mill., diam. 3. 



Hah. Rio Janeiro. 



This species is nearly allied to T. Knockeri^ Smith, Proc. 

 Zool. Soc. 1872, from West Africa ; but it may be known 

 from it by its larger size, and the absence of the plications at the 

 upper part of the body-whorl ; the columellar fold also is less 

 strongly developed. The very fine ridge in the middle of 

 the sutural channel produces the appearance of a double edge 

 to the whorls. 



Tornatina persiana, B.M. 



T. testa minutissima, breviter cylindracea, alba, incrementi lineis 

 curvatis rugosa ; anfract. 3, primus ex tuberculo magno constat, 

 caeteri superius lira magna rotundata circumcincti ; sutura de-
