body to the test, the apertural end extended into an elongate tapering 

 neck, and the basal end broadly rounded. Such specimens are figured 

 here, but they are not common in our material, the only specimens 

 occurring at Albatross Stations H3819, latitude 15° 25' S., longitude 

 148° 08' W., in 1,123 fathoms, and H3879, latitude 16° 03' S., longi- 

 tude 143° 32' 30" W., in 1,084 fathoms.

The type figure given by Montagu shows a clavate form with a 

 rather long, tapering, nearly cyhndrical neck, and the body of the test 

 with a few distinct raised costae. Later authors have very largely 

 referred this specific name to a form which has the test with a similar 

 type of neck, but the costae Umited to the basal portion of the test. 

 In the collections studied here we have limited the name to similar 

 specimens. These have occurred rarely and only in shoal water 

 from off Ro tonga, and from Viva Anchorage, Fiji. 



lagena GLOBOSA (Montagu) 



Plate 4, Figures 10a, b 



A rather complete list of references to this species has already been 

 given in Bulletin 104.^ So many forms have been referred to this 

 species by numerous authors that it has come to be a sort of dumping 

 ground for almost any globular form of Lagena or Entosolenia. It is 

 to be suspected that many of the forms referred to this species are 

 really the prolocula of various genera of the Lagenidae, which at that 

 stage are indistinguishable from forms of Lagena. Such globular 

 forms are rare in the collections of the South Pacific which we have 

 studied, and occur as single specimens. Outside of one specimen from 

 Mokaujar Anchorage, Fiji, the other three are from Albatross stations, 

 data for which are given in Table 1 1 .
