TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS" 39 



Genus PYRULINA d'Orbigny, 1839 



"Pyrulines, Les," d'Orbigny, Ann. Sci. Nat., vol. 7, p. 267, 1826. 

 Pyrulina d'Orbigny, in de la Sagra's "Cuba" (Foram.), p. 107, 1839 (non 

 1826, vernac). 



Genoholotype. — Pyrulina gutta d'Orbigny. 



Test fusiform or cylindrical; chambers more or less elongated and 

 embracing, arranged at first in a somewhat quinqueloculine series, 

 later becoming biserial. Upper Cretaceous to Recent. 



There has been some question as to the use of the genus Pyrulina, 

 and an attempt has been made to substitute the name Apiopterina 

 Zborzewski, 1834, on the basis that d'Orbigny used the "e" at the 

 end of the subgeneric name Pyruline. As Zborzewski's species 

 A. orbignyi is entirely unrecognizable, and as it is even a question 

 in what genus it should be placed, the name is invalid, and Pyrulina, 

 which was used later by d'Orbigny, is the first name available if the 

 1826 name should be left out. The same is true wdth Glohulina, the 

 species Raphanulina humboldtii Zborzewski being entirely unrecog- 

 nizable and the genus therefore being invalid. 



PYRULINA CYUNDROIDES (Roemer)

The specimens of this genus are extremely rare in our Pacific collec- 

 tions. The form figured under this name is from Albatross Station 

 H3971, latitude 4° 25' N., longitude 171° 13' E., in 2,505 fathoms.

 Pyrulina extensa Cushman and Ozawa, Proc. U. S. Nat. Mus., vol. 77, art. 6, 



p. 53, pi. 12, figs. 5a-c, 1930. 



Test elongate, fusiform, margin almost entire, initial end more or 

 less pointed, apertural end produced into an elongate, cylmdrical 

 neck; chambers not numerous, inflated; sutures fairly distinct, but 

 not depressed, except in the case of the last-formed one; wall more or 

 less hispid, the last chamber especially more inflated and spinose and 

 often covered with fistulose tubes; aperture at the end of a long neck, 

 not radiate. 



This deep-sea species has been recorded from the South Pacific 

 previously, and also from the Pliocene of Fiji. The figured specimen 

 is from Albatross Station H3791, latitude 7° 58' S., longitude 139° 9' 

 W., in 2,287 fathoms, and seems to be rather typical.
