In 1866 Prof. E. D. Cope presented before the Acad. Nat. Sciences in 
Philadelphia a specimen of Aturia-like shell, which he described as fol- 
lows, under the name Aturia paucifex: ‘Uncovered chambers, nine; sep- 
tary processes elongate, acuminate, shallow, diverging outward from a spiral 
line joining their bases; well separated from the succeeding septa; dorsal 
portions of the septa short, very eccentric as regards each other; ventral 
portions opposite them, forming nearly a right angle with the ventral out- 
line. Siphuncle small, more dorsal than the end of the dorsal fourth of 
the diameter. Ventral surface broad rounded; septal processes scarcely 
visible on the ventral view.” Diameter of the last chamber 3 in. 11 lines; 
of first visible (at siphuncle), 22 1. Median diameter | (from penultimate 
chamber) 8 inches. 
Among the New Jersey cephalopoda received from the Academy of 
Natural Sciences of Philadelphia, I find a large internal cast of an Aturia- 
like species under the name Nautilus orbiculatus, with the locality ‘‘ Glou- 
cester, N. J.” On the cast is pasted a label, bearing the name ‘“Aturia 
paucifex ; Cope’s type, Hercoglossa,” then one or two words obliterated, after 
which follows ‘Glassboro, Gloucester Co., N. J... The words Aturia pau- 
cifec Cope’s type, and the obliterated words, have been crossed out with 
pencil and ‘‘N. orbiculatus?” appears in ink above the original name. The 
specimen I believe to be the type of Prof. Cope’s species, as it agrees 
with his description and also with the measurements given, but does not 
agree with Prof. ‘Tuomey’s description of N. orbiculatus ; at least not as I 
understand some parts of his very short and obscure diagnosis, which is 
as follows: “Shell somewhat discoid, thick in the center and gradually 
thinner toward the circumference; last chamber very large, spreading at 
the umbilicus; siphunculus nearly central; septa profoundly undulated, 
showing on the back a recurved lip.” Prof. Cope appears to have con-
