VOL. III.] LoTver Californian Shells. lo 



Amer. Jour, of Conchology, vol. ii, gives two others, all these in- 

 tergrading. 



20. H. ROWELLii Newcomb, 1865. "Arizona" Dr. Frick. 

 This has lately been confirmed by specimens obtained near Phoenix 

 (Pilsbry). A variety from near Mulej6, lat. 26^ 52', was described 

 as a new species, ' ' H. lohrii ' ' Gabb. 



An intermediate locality has been recently discovered by Dr. S. 

 Bowers in San Gorgonio Pass, near lat. 33° 40", at the east base of 

 the San Jacinto Mountains, eight miles south of Indio Station, 

 and about the level of the former lake (or sea), among granitic 

 rocks. There is a limestone bed a little higher up near which they 

 may be found living. Like all found, so far, except Gabb's var. 

 Lohrii, they were dead shells, but retained the band, which was 

 faded out in Newcomb's type, as described by him. For'this reason, 

 doubtless, their identity was not recognized by Gabb at first, and 

 Dr. Yates also added a synonym or variety in describing Dr. Bow- 

 ers' shell, as " i/. carpenieri var. Indioensis'' in Nautilus, vol. iv, 

 p. 63, 1890. It is also reported with some doubt from " Guade- 

 lupe Island, Dr. Palmer" (Binney), who got only young shells, 

 while Bryant found only H. carpenteri, but in perfect condition. 



21. H. (rufocincta?) FACTA Newcomb, 1864. Santa Barbara 

 Island, lat. 33° 30', and San Nicolas Island J. G. C. (types), the 

 large forms from Catalina Island, lat. 33° 20' " Guadelupe Island, 

 lat. 29° " Palmer, Dunn. Some of these are subangled and um- 

 bilicate. Through H. gabbi Newc, and some fossil forms, all are 

 closely connected. 



22. H. STEARNSIANA Gabb, 1867. El Rosario, lat. 29° 55', to 

 San Tomas, lat. 31° 35', Gabb, on west slope only. Coronado Is- 

 land, lat. 32° 25', Hemphill. Near San Diego, Orcult. A connect- 

 ing link between the typical H. kelleilii and those northward, con- 

 sidered varieties of that species. Mr. Gabb's most southern local- 

 ity seems to fix the southward range definitely. 



23. H. TRASKii Newcomb, 1861, and var. carpenteri Newc, 

 1 861. Los Angeles, lat. 34°, (type) Trask, to Point Conception, 

 lat. 34° 25', Yates, and San Diego, lat. 32° 40',/ 6^. C. The 

 variety from Tulare Valley, lat. 36°, (type), to Coronados Island, 

 Dunn, lat. 32° 25', and Guadelupe Island, Bryant, lat. 29°. 

 The " H. remondii'^ Gabb (not Tryon, 1863), scarcely differs
