Appendix. 

 Family ACM^ID^ Cpr. 



Dr. THIELE, in his continuation of Troschel's Das Gebiss der 

 Schnecken, recognizes two subfamilies of Acmceidce, identical with 

 those adopted by me on p. 6 of this volume. 



ACM^EA VIRIDULA Lam. (p. 32). Keeve, on a suppressed page of 

 the Conchologia Iconica, names this species P. nivalis. 



ACM^EA VARIABILIS Sowb. (page 34.) 



Philippi changed the name of his P. lineata to P. grammia in the 

 index to the Abbildungen. This name will also fall into line in the 

 procession of synonyms after A. variabilis. 



ACM^EA ANTILLARUM Sowb. (p. 38). 



This name will take precedence over that of candeana, elegant, 

 etc., the former of which was used in the text, p. 38. 



Sow r erby's figure of Lottia antillarum, on the plate first cited 

 below, is an excellent and characteristic picture of this species in its 

 finest development. 



The synonymy will stand as follows : 



Lottia antillarum SOWERBY, Genera of Shells, fig. 4. (Issued 

 before 1831.) 



Lottia antillarum SOWERBY, A Concholog. Manual, p. 59, fig. 231, 

 1839. (A somewhat different color-form.) 



Lottia antillarum Sowb., REEVE, Conch ol. System., pi. cxxxvii, f. 

 4 (printed from same plate as Sowerby's Genera) 1842. 



Acmcea antillarum Sowb., PILSBRY, The Nautilus, Dec., 1891, 

 p. 85. 



Patella tenera C. B. ADAMS, Proc. Bost. Soc. N. H. ii, p. 8 (1845). 



Patella tenera Ad., REEVE, Conch. Icon. fig. 104. 



Patella candeana ORB., Moll. Cuba, ii, p. 199, atlas pi. 25, figs. 

 1-3. 



Acmcea candeana Orb., DALL, Catal. Mar. Moll. S. E. U. S., p. 

 159. 



Acmwa candeana Orb., PILSBRY, Manual of Conchology, xiii,' p. 

 38, pi. 5, figs. 91-95, and pi. 42, figs. 92-95. 



f Patella {Acmcea?} elegans PHILIPPI, Abbild. u. Beschreib. iii, p. 

 34, Patella p. 6, pi. 2, fig 2 (1846). 



? Not P. antillarum Sowb., PHILIPPI, Abbild. iii, Patella, pi. 2, fig. 

 12.
