OF CONCHOLOGY. 73 



The following are the recent species which may be referred to 

 this genus: 



Crania Suessi, Reeve, Mon. Crania, Conch. Icon. pi. 1, fig. 2, 



1862, from Sydney, Australia. 

 Crania rostrata, Hoeninghaus, Mon. Crania, p. 3, No. 3, f. 3, 



1828. Rve., 1. c. pi. i, fig. 3, 1862. 

 Mediterranean and (?) West Africa. 



I have received a specimen of this species from the Mediter- 

 ranean through the kindness of Mr. Davidson. It is quite 

 distinct from C. anomala. Deshayes' synonymy is very erroneous, 

 and includes both anomala and the presumed variety turbinata. 



Crania anomala, Miiller, (as Patella a.), Prodr. Zool. Danica, 

 2870, 1766. Reeve, 1. c. pi. i, f. 4, 1862. 



== Patella distorta, Montague, 1808, P. Kermes, Humphrey, 

 Criopus orcadensis, Leach, 1852. Orbicula norvegica, 

 Cuvier, 1798, and Lamarck, 1801 (but not of Sowerby, 

 1822, Rang, 1829, nor Blainville, 1825), + Criopoderma 

 turbinatum et Criopus fimbriates pars, Poli, 1792, -f- Cra- 

 nia personata, Lamarck, 1819, + Crania ringens, Hoen- 

 inghaus, 1828, -4- C. rostrata, Deshayes (pars), 1836 (not 

 Hoeninghaus), &c. &c. 

 North European Seas. 



Crania anomala, var. alba, Jeffreys, Brit. Conch, v, p. 165, 

 1869. 

 Shetland and the Hebrides. 



Crania {? anomala var.) Pourtalesii, Dall. Bull. Mus. Comp. 

 Zool. iii, No. 1, p. 35, pi. 1, fig.. 7, a, b, May, 1871. 

 Florida Keys. 



The few specimens obtained by M. de Pourtales differ in 

 smaller size and in strong radiating rugosities, as well as in tex- 

 ture and color, from the typical anomala. A larger series of 

 specimens will perhaps establish its specific rank. For the 

 present, however, I prefer indicating it under a varietal name. 



The seventy-four synonyms of anomala will be found in the 

 Report already mentioned. I am indebted to Mr. G. W. Tryon 

 for an examination of Poli's work and evidence as to its non-bino- 

 mial character, which should exclude it from all strict synonymy. 

 Mediterranean specimens received from Mr. Jeffreys establish 

 the identity of C. turbinata, Poli, with C. anomala. 



Crania Japoniea, A. Adams, Annals and Mag. Nat. Hist. 3d 

 ser. xi, p. 100, 1863. 

 Gotto Islands, Japan, 71 fms. 

 The muscular scars are exceedingly prominent.
