712 DEEP WATER MOLLUSKS AND BRACHIOPODS— BALL. vol.xvii. 



Tliis Splendid species may prove not to be a Beringius, but I have not 

 had an opportunity to examine the dentition, and it seems coucholog- 

 ically more lilte that genus than lilce Sipho. 



MOHNIA FRIELEI, Dall. 

 Plate XXIX, tig. 8. 

 Molinia Frielei, Dall, Proc. U. S. Nat. Mus., xiv, p. 186, 1891. 

 Station 2SG0, in the North Pacific off Queen Charlotte Sound, British 

 Columbia, in 876 fathoms, green mud; bottom temperature 36.5° F. 

 No. 122656, U.S.N.M. 

 This is the second species of Friele's interesting genus. 



TROPHON (BOREOTROPHON) DISPARILLS, Dall . 

 Plate XXVII, tig. 4. 

 Trophon {Borcolrophon) dispariUs, Dall, op. cit., p. 189, 1891. 

 Station 3048, in the Pacific off Gray's Harbor, Washington, in 52 

 fathoms; bottom temperature 41° F. Ko. 122559, U.S.N.M. 



This species has also been dredged in the Aleutian region; off 

 San Diego, Cal. ; at station 3431, in the Gulf of California off Mazatlan, 

 in 995 fathoms, mud, bottom temperature 37° F.; and station 3392, in 

 the Gulf of Panama, in 1,270 fathoms, hard bottom, temperature 36.4° 

 F. (Nos. 123021-2, U.S.lSr.M.) This very remarkable range of distri- 

 bution is explained by the temperature and the absence of any marked 

 ridges in the sea bottom which might serve as barriers to southward 

 migration. 1 see no reason why it might not be found all the way south 

 to Cape Horn in water of the proper temperature. 



TROPHON (BOREOTROPHON) SCITULUS, Dall. 

 Plate XXVII. tig. 5. 

 Trophon {Boreoirophon) scitalus, Dall, op. cit., p. 188, 1891.

 fathoms, green mud; bottom temperature 38.6° F. No. 122557, U.S. 



N.M.
