description. — Test nautiloid, coarsely porous, small, compressed; lat- 

 eral surface nearly equally convex; depressed at the umbilici; peripheral 

 edge round; ajierture an arched nearly median opening upon the inner

In the Xorth Atlantic off Bermuda good specimens of Anomalina 

 ammonoides were taken by the Challenger expedition but no other speci- 

 mens were found in the North Atlantic. These were at the depth of 

 435 fathoms. It was recognized in dredgings in the South Pacific at 

 the depths of 210 fathoms (near the Fiji Islands), also at 1350 fathoms 

 from the same vicinity, 275 fathoms off ISTew Zealand, and another in 

 Humboldt Bay at 37 fathoms. Parker and Jones obtained it from the 

 Eed Sea at depths of 372 and 678 fathoms, also in anchor muds near 

 Hong Ivong and shore sands at Melbourne. It is common as a fossil 

 from Cretaceous time on through the Tertiaries.
