56 PROCEEDINGS OF THE NATIONAL MUSEUM vol.89 



This subspecies differs from Haliotis c. calif omiensis in having the 

 perforations much larger and more distantly spaced, and con- 

 sequently much less numerous. 



The other named shells placed in the synonymy of this subspecies 

 above I believe represent individual variations, not isolated geo- 

 graphic races, which if they must be referred to by name had best 

 be designated "forms" rather than "subspecies." 



This subspecies embraces all Halioth craeherodii except those from 

 Guadalupe Island: 



Hauotis ckacherodii splendidula Williamson : 



Mrs, Williamson stated under the above designation that a number 

 of shells found at one time at Point Vincent, Calif., have brilliant 

 blotches of color in their interior, somewhat like H. fulgens Philippi, 

 and some have spots of brown. 



Hauotis cbaoherodii holzneki Hemphill : 



The specimen figured by Dr. Dall, U.S.N.M. No. 199890, is a dis- 

 torted, decidedly twisted, individual having perforations. Hemp- 

 hill's description calls for an absence of perforation, in which respect 

 Haliotis craeherodii Jiolzneri would agi'ee with Haliotis iinperforata 

 Dall. 



Hauotis crachebodii imperfobata Dall : 



Under this Dr. Dall says: "In the Nautilus for December, 1910 

 (p. 96), I described a unique form of this species which is entirely 

 imperforate, never having had any perforations, but appears normal 

 in every other respect. Wliile this can hardly be termed a variety 

 it seems well to give it a name in order that it may be kept in mind 

 by those interested in teratology of mollusca. The specimen is U. S. 

 Nat. Mus. Cat. No. 219850, and measures 100 mm. in length by 42 

 in height and 95 in width, and was collected on the coast of California 

 not far from San Pedro." 



Hauotis roseIa Orcutt: 



Orciitt distinguished tliis from the typical form on account of its 

 "rich, extremely beautiful, reddish epidermis." 



Haliotis corrugata diegoensis Orcutt: 



The type of Mr, Orcutt's subspecies is in the collection of the U. S, 

 National Museum (No, 162007) and is plainly a large, decidedly 

 worm-eaten, senescent Haliotis craeherodii.
