TROPICAL PACIFIC FOBAMLTSTIFERA OF ALBATROSS 49 



Test composed of subglobular chambers connected by slender cylin- 

 drical necks; the main body of the chambers with a calcareous base 

 and the exterior composed of rather coarse calcareous fragments of 

 various sorts; the apertural end of each chamber with an elongated 

 tubular neck free from agglutinated material, with a definite lip and 

 a series of platelike teeth inside the lip. 



Brady described this species from the following three stations: 

 Humboldt Bay, on the north coast of Papua, 37 fathoms; off Raine 

 Island, Torres Strait, 155 fathoms; and off Tongatabu, Tonga 

 Islands, 18 fathoms. 



Although the species has been referred to by numerous authors, 

 most of the specimens from the Indo-Pacific belong to the following 

 variety, which has closely set chambers and a very short neck, and 

 the teeth in the aperture are quite different. The only specimens we 

 have that can be referred to Brady's species are fragments that are 

 here figured from Nairai, Fiji. They show a characteristic, elongate, 

 small neck and definite lip.

 Washington Publ. 342, p. 53, pi. 19, figs. 1-4, 1924. 



Variety differing from the typical in the closely set chambers, 

 which increase greatly in size and diameter as added; the aperture 

 tubular, but short and stout with a definite everted phialine lip, and 

 very coarse teeth in the opening. 



Numerous figured specimens such as those of Sidebottom from the 

 Mediterranean and Heron-Allen and Earland from the Kerimba 

 Archipelago seem to belong to this variety rather than to the typical 

 form. I had this variety in abundance from Samoa, where it reaches 

 a size up to 2.5 mm. 



In the present collections it has occurred in typical form from 

 Mokaujar Anchorage, Fiji; off Levuka, Fiji, 12 fathoms; and off 

 Nairai, Fiji, 24 fathoms; with somewhat less typical specimens from 

 off Rotonga (= ? Rarotonga, Cook Islands), 7 fathoms.

Chambers somewhat irregularly pyriform, the wall with a cal- 

 careous base, and the exterior of rather fine fragmentary material; 

 the apertural end with an elongate, rather stout, cylindrical neck, and
