166 APPENDIX-ACM.EID.E. 



Appendix. 

 Family ACM^ID^ Cpr. 



Dr. Thiele, ill his continuation of Troschel's Das Gebiss der 

 Sehnecken, recognizes two subfamilies of Acmceidce, identical with 

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



AcM.iiA viRiDULA Lam. (p. 32). Reeve, 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 Ahbildungen. This name will also fall into line in the 

 procession of synonyms after A. variahilis. 



ACM^TSA ANTILLARIIM Sowb. (p. 38). 



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

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



Sowerby'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 antillariivi Sowerby, Genera of Shells, fig. 4. (Issued 

 before 1831.) 



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

 1839. (A somewhat diflTerent color-form.) 



Lottia antillarum Sowb., Reeve, Conchol. System., pi. cxxxvii, f. 

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



Acmoea 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. 



Acnuea candeana Orb., Dall, Catal. Mar. Moll. S. E. U. S., p. 

 159. 



Acmoia candeana Orb., Pilsbry, Manual of Conchology, xiii, p. 

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



f Patella {Acmmaf) elegans Philippi, Abbild. u. Besehreib. iii, p. 

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



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

 12.
