FOKAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 407 



rounded; sutures distinctly depressed, wall ornamented with a regular 

 pattern of elliptical depressions, arranged in rows longitudinally, 

 the depressions of each row alternating regularly with those of the 

 adjacent rows. 



Length up to 1 mm. or slightly more. 



The species was described from Murray Island, on the Great 

 Barrier Reef of Australia, from shallow water. Its nearest relative 

 seems to be ^S. foveolata Egger, from which it differs very much in 

 shape and general appearance. 



It was found in few numbers at five stations in 19 to 318 fathoms 

 (35 to 582 meters) ; bottom temperature at the only station given, 

 63.1° F. (17.2° C).

Spiroloculina grata Terquem (?) and late authors. 



A study of shallow-water West Indian material and comparison 

 with d'Orbignj^^'s figures show that our common typical species so 

 characteristic of coral-reef regions should have the name S. antil- 

 laruni d'Orbigny. 



A comparison of the two references given by Brady in the Chal- 

 lenger Report shows that of the two, d'Orbigny's figure is more char- 

 acteristic, not only of most of our coral-reef material, but actualh' 

 nearer the S. grata as figured by Bradjf. On the other hand, Brady 

 refers to S. antillea and figures a specimen which only remotely sug- 

 gests the original of d'Orbigny. This specimen was from 350 fathoms 

 (640 meters) off the coast of Brazil, while d'Orbigny's original was 

 from ''shore sands." The West Indian material which I collected in 

 Jamaica shows clearly that the common shaUow-water species of 

 those waters is identical with the species figured and named by 

 d'Orbigny S. ardiUarum. The species seems to be very widely dis- 

 tributed in the tropics, and even allowing that Terquem's Pliocene 

 specimen from the Isle of Rhodes is the same, d'Orbigny's name
