Description. — Test elongate, tapering toward either end, chambers 

 more or less triangular in cross section, early chambers with longitu- 

 dinal costas often prolonged into spinose projections at the apical 

 end; later chambers with smooth walls and more loosely arranged; 

 aperture with a tubular neck gradually merging into the outline of 

 the chamber at the proximal end and with a definite phialine lip at 

 the outer end . 



Length about 0.75 mm. 



Distribution. — This variety has not been recorded from the North 

 Pacific. Brady recorded it from off Tristan d'Acunha, Egger from 

 two stations off New Amsterdam and West Australia, and Chapman 

 from the Arabian Sea. 



The only North Pacific material I have seen is from Nero station 

 1306, in 1,208 fathoms between Yokohama and Guam. The figured 

 specimen is from this station. 



Brady described this as a distinct species and it certainly has but 

 little in common with 77. angulosa Williamson. With the exception 

 of one of the stations recorded by Chapman and one by Egger, it has 

 not occurred in company with 77. angulosa, but as these are two from 

 only five stations the percentage is rather large. The spinose condi- 

 tion of the early chambers is also different from what is usually seen 

 in 77. angulosa.

 p. 414. 



Description. — Test much elongated, early chambers in a close 

 spiral, later ones drawn out and considerably separated from one 

 another; chambers, especially the later ones, concave below, the 

 peripheral edge angular and projecting; upper surface of the cham- 

 bers convex and ornamented by coarse longitudinal costs which pro- 

 ject at the peripheral edge, making it serrate; aperture with an elon- 

 gated tubular neck, the lip not well developed. 



Length about 0.5 mm.
