nearer to d'Orbigny's T. hauerii than to any other Textularian. Brady regarded 

 T. hauerii as merely a modification of T. gramen {ut supra) characterized by less 

 angular edges, but the Kerimba specimens are sufficiently marked and divergent 

 from T. gramen, as represented in these dredgings, to render the separation of the 

 specimens desirable. In the somewhat rough texture of the shell their affinities 

 appear to lie rather in the direction of T. candeiana than of T. gramen. 



The Kerimba specimens of T. hauerii have, as a rule, about eight pairs of cham- 

 bers regularly increasing in breadth and thickness, and with the sutural lines some- 

 what depressed owing to the inflation of the chambers. Marginal edge lobulate and 

 varying from rounded in the latter portion of the shell to acute or subcarinate in 

 the initial portion. Surface-texture somewhat coarse, but neatly agglutinate. The 

 species is most abundant at Stns. 1 and 12, reaching its best proportions at the 

 latter. T. hauerii was recorded by d'Orbigny from the Tertiaries of Vienna. It is 

 probably widely distributed, but has not been separated from the records of T. 

 gramen. 



In the above characterization of this species I heartily agree, and 

 from two stations at least a similar form occurs. The specimens are 

 from Albatross stations D5181, off eastern Panay in 26 fathoms (48 

 meters), and D5276, China Sea off southern Luzon in 18 fathoms 

 (33 meters).

Numerous records for this species, mostly from the southern por- 

 tion of the area, have been obtained. These range in depth from 10 

 to 80 fathoms (18 to 146 meters), with a single record from D5574, 

 north of Tawi Tawi Group, 340 fathoms (622 meters), and except 

 for two other stations all the depths are for less than 40 fathoms (73 

 meters). Bottom temperatures are given in only two cases, these 

 being 58.6° and 76.3° F. (14.7° C. and 24.6° C). 



The largest specimens are about 3 mm. in length.
