LIOMESUS CANALICULATUS Dall. 
Plate XXXVIII, fig. 2. 
Buceinopsis canalicidatn Dall, Proc. Cal. Acad. Sci., V", Feb., 1874, p. 252 (extras 
p. 6). — KoBELT, Conch. Cab., 2d ed., Buccinum, 1887, p. 102, pi. lxxxviii, 
fig. 10. 
Liumesus canaUculatux Dall, Sci. Expl. Alaska, Bucdnidpe, 1879, pi. iv, fig. 4. 
North end of Nunivak Island, Bering Sea, Dall. U.S.N.M., 108977. 
Shell white with a yellow velvety periostracum. This species was 
figured in my Exploration of Alaska, Buccmidce^ Plate iv, %. 4, and 
L. mix as tig. 5, 1879; but the text for these plates is still unprinted. 
LIOMESUS OdiDES Middendorff. 
Tritonium odides Middendorff, Bull. Acad. St. Petersb., VII, 1848, No. 16, p. 16; 
Malak, Ross, II, 1849, p. 175. 
Tritonium ovoidcs Middendorff, Sib. Eeise, 1851, p. 236, pi. viii, figs. 7, 8. 
f Liomesus ovoides Stimpson, Canadian Nat., new ser. II, Oct., 1865, p. 364. 
Buccinum ovoides Kobelt, Conch. Corb., 2ded., Buccinum, 1883, p. 72, pi. lxxxvii, 
fig. 6. 
Tugur basin, Okhotsk Sea, Middendorff. Bering Strait, Stimpson. 
This species, by an easy typographical error, has two names in 
Middendorff 's woiks. It seems to differ from Z. canaliculatu.s Dall by 
its shorter spire, less regular form, and less distinct spiral sculpture. 
The species found by Stimpson at Bering Strait is probabh^ ca?udfcu- 
Jatus. Further material ma}^ show the desirability of uniting the two, 
in which case Middendorff's name has twenty-five years priority. 
In my plates of Bvccinidce^ specimens of Liomesus daJei Sowerby, 
var, f'hui'nea Sars, from the Doggerbank, were figured for comparison 
with the Alaskan forms. My friend Dr. Kolielt, in the absence of 
the text relating to these plates, w^as led to suppose them from Alaska, 
and applied the varietal name of Bckrlnghina to them.^ But this 
species is not found in the western hemisphere as far as I know. I 
am inclined to doubt the identity of the Crag form with the recent one, 
and should be disposed to adopt Sars's name in a specific sense. I 
have never seen any recent specimens at all resembling the massive 
shells from the British Crag. I may add that another species of this 
genus, L. nassidd, was recehtlv described l)y me from Bering Sea. 
ASTYRIS AURANTIACA Dall. 
Plate XXXIV, fig. 5. 
Astyris mirantiaca Dall, Am. Journ. Conch., VII, 1871, Pt. 1, p. 115, pi. xv, 
'fig. 13 (bad). 
Monterey, at low water, Dall. U.S.N.M., 12313. 
The color varies from orange yellow to brown or yellow with zigzag 
brown markings. It is generally subtranslucent.
