ATYS. 269 



Mr. Sowerby's mistakes in regard to the authority and localities 

 of Gould's species have been corrected by E. A. Smith, Ann. and 

 Mag. N. H. 1872, p. 345. It is not easy to see how so many errors 

 could be made as occur in the later volumes of the Conchologia 

 Iconica, even when it is understood that they were written with- 

 out reference to the literature of the groups monographed. 



A. LABIOSA Philippi. Unfigured. 



Shell small, short, ovate, cylindric, very smooth, very delicately 

 transversely striated at the base when viewed under a strong lens ; 

 spire retuse, whorls 2 ; aperture linear, dilated at base and unipli- 

 cate, continued above in a channel to the center of the vertex ; 

 margins of inner and outer lips thickened, obtuse. Alt. 1, diam. 

 if lines. (Ph.*). 



China (Largilliert). 



Sulla labiosa PH., Zeitschr. f. Mai., 1851, p. 64. 



The generic position is uncertain. An error (probably typo- 

 graphical) in Philippi's description has been corrected above. 



A. TRANSLUCENS A. Adams. Unfigured. 



Shell cylindric-ovate, thin, pellucid, transversely striated at the 

 ends, the striae distant, the median area glabrous. Aperture nar- 

 row ; inner lip straight, truncated anteriorly ; outer lip somewhat 

 straightened in the middle, posteriorly twisted and produced, ante- 

 riorly crenulated (Ad.).

Alicula translucens A. AD., Ann. Mag. N. H., (3), ix, p. 159. 



This species most nearly resembles Alicula succisa Ehrenberg, 

 from the Red Sea, but is narrower and more cylindrical in form, 

 and is thin and nearly transparent. (Ad.). 



A. SECALINA A. Adams. Unfigured. 



Shell cylindric-ovate, rimate, the apex subtruncate and slightly 

 perforated, semi-opaque, corneous, transversely striated throughout, 

 striae distant, obsolete in middle. Aperture linear; inner lip 

 oblique, somewhat thickened ; outer lip a little straightened in the 

 middle. (Ad.).
