NO. 1264. ILL VSTRA TIONS OF A M ERICA N SHELLS— DA LL. 553 
Color of the shell pinkish waxon. tho apex somewhat darker, with 
variable delicate brown Hainninles. and darker brown ones on the 
periphery of the last whorl. The base is destitute of ilammules, and 
the pillar is white. These delicate colors in this as in most shells tend 
to fade somewhat in the cabinet.

Monterey, Dall; Santa Barbara, Button. U.S.N.M., 103005. 
The color of the shell is pearly with bronze-yellow pencilings 
obliquel}' to the suture. The original type was long inaccessible, but 
another specimen was obtained by Mr. Button, and it also occurs in 
the Pleistocene. Only two recent specimens are known. 
SOLARIELLA CARLOTTA, new species. 
Shell rather depressed, pearly white covered with a dense, rather 
fibrous, olive-gra}' periostracum; nuclear whorls eroded, but the shell 
exhi])its about four and a half whorls; sculpture of, on the base eight 
miiuitely distantly nodulous spiral threads stronger and more distant 
as one proceeds from the verge of the umbilicus to the periphery; 
peripheral spiral separated from another above it by an excavated 
channel; these two are the strongest on the shell, and between the upper 
one and the suture is another nmch feebler thread; the upper two are 
all that shoW' on the spire, as the outer lip runs just above the peripheral 
thread; the radial sculpture comprises incremental lines, and on the 
last whorl about twenty low narrow somewhat oblique riblets about a 
millimeter apart, extending from the suture to the first peripheral 
keel, but not beyond; these riblets nodulate the weak spiral, but are 
only about half as numerous as the nodules on the peripheral spirals; 
suture distinct, not channeled; ba.se rounded; the umbilicus funicular, 
of moderate size, bounded by an inconspicuous keel, above which the 
walls are verticall}^ striated; margins of the aperture simple, sharp, 
the upper lip advancing where it joins the body; pillar lip thin, slightl}" 
excavated, the distal angle not prominent. Alt. 9.0; max. diam. 
13.5 mm. 
Dredged at station 33-12, ofi' the Queen Charlotte Islands, in 1,588 
fathoms, ooze, bottom temperature 36^.3 F., bj' the U. S. Fish Com- 
mission steamer Albatross. U.S.N.M., 109020. 
This species resembles in its t^^pe of sculpture S. actinopliora of the 
Antilles; thegeneral appearance is dull and unattractive. Only a single 
individual, tenanted by a small hermit crab, was obtained.
