Shell of about the size and form of LZ. subauriculata, with fine concentric incre- 
mental lines and feeble radial riblets, discrepant on the two valves, slightly 
deflected backward distally ; both valves with a well-defined median sulcus, which 
on the interior of the valve is bordered on each side by a single distinct rib; right 
valve externally has one rib in front of the sulcus and seven to nine behind it; 
left valve with seven or eight ribs on each side of the sulcus; the ends of the ribs 
serrate the ventral margin; beaks small, prominent; hinge line subequally 
divided, the auricular angles prominent ; the amphidetic area narrow; the resili-

These little shells were sent to the Museum some time since by Mr. Suter, in 
whose honor they are named, and in working out the “ Albatross” species were 
determined to be new.

Crenella divaricata Orspieny. 
Nuculocardia divaricata Orbigny, Moll. Cubana, 1847, 2, p. 311, pl. 27, figs. 56-59. 
Crenella divaricata Dall, Trans. Wagner Inst. Sci., 1898, 3, p. 808. 
On the Atlantic Coast this shell ranges from North Carolina to Barbados, and 
in time from the Oligocene of Santo Domingo to the recent fauna. On the 
Pacific it has been dredged by the ‘‘ Albatross ” in the Gulf of California and in 
Panama Bay, at station 2799, in 30 fathoms, and station 2805, in 51 fathoms, 
muddy bottom. 
Crenella megas Datu. 
Crenella megas Dall, Proc. U. S. Nat. Mus., 1902, 24, p. 559; 1903, 26, p. 950, 
pl. 62, fig. 4. 
Dredged by U. 8S. 8. “Albatross,” at station 2795, Panama Bay, in 33 
fathoms, sand, one valve, bottom temperature 64° F. U. S. N. Mus. 96,256. 
This is probably the largest species of the genus.
