THE NAUTILUS. 
Median valves scarcely beaked, the posterior outline of each con¬ 
cave. Lateral areas raised, sculptured with two or three radial 
grooves, becoming more numerous toward the bases, and inconspic¬ 
uous growth-striae. Central areas having a wide smooth triangle in 
the middle; sculptured hi front of each diagonal slope with narrow, 
spaced impressed longitudinal grooves , not half as wide as the inter¬ 
vals, and which form a sculptured band, increasing but little in 
width outwards. Toward the beaks of each valve these grooves dis¬ 
appear entirely, but are replaced by distinctly painted green lines, 
very curiously simulating the grooves. Anterior valve with about 
28 convex radial riblets, some split at base. Posterior valve with 
subcentral subprominent mucro, and slightly concave posterior 
slope, weakly radiated. Interior pale blue, the sutural laminae 
white. Sinus very narrow. 
Girdle densely clothed with very convex, shining, polished solid 
scales, those in the middle of its breadth largest, measuring, six-tenths 
mill, in width. 
Length 38, breadth 18 mill, (exclusive of girdle). 
Hab. St. Vincent Gulf (W. T. Bednall). 
I have not much doubt that this shell is a form of Reeve’s cereus, 
but the coloration is different, the number of riblets on the pleura is- 
not nearly so great. Mr. E. A. Smith has united cereus to the Mediter¬ 
ranean C. siculus (=olivaceus ), but I can hardly endorse such a 
lumping of forms from totally different areas. 
ISAIAH GREEGOR. 
We have heard with deep regret of the death of Mr. Isaiah 
Greegor, which occurred on the 26th of July at his home, Cuyahoja 
Falls, Ohio. 
Mr. Greegor was not only an extensive dealer in shells, but also 
an ardent and earnest Conchological student. Though for many 
years engaged in a business requiring strict attention and skilful 
management, he never allowed this to interfere with the promptings 
of his generous heart; a fact which was constantly exemplified by 
his timely suggestions and gifts of specimens to friends and others 
engaged in Conchological pursuits. He also took much interest in 
the completion of the American Association’s collection. His last
