the Fish Hawk at station 7565. This may not indicate that the species 
is rare for it is a small one and on accomit of its resemblance to the 
rest of the bottom material is easily overlooked. It is common on 
the shores of Europe. 
BULIMINIDAE. 
Bolivina punctata d'Orbigny. 
Plate 5, fig. 13. 
Bolivina jmnctnta d'Orbigny, '39, p. 61, pi. 8, fig. 10-12; Brady, '84, p. 
417, pi. 52, figs. 18, 19; Flint, ^99, p. 292, pi. 38, fig. 1. 
A number of specimens of Bolivina were obtained from the surface 
of^ old shells of Myfilus ediilis attached to the outer piles of the U. S. 
fisheries dock at ^Yoods Hole. \Yhile the specimens Avere much 
broader than the typical Bolivina punctata, yet they are very similar 
to the broader form of this species. The colors sho's\ii in fresh speci- 
mens are very striking. In a living state the proloculum and the 
succeeding chambers exce})t the last three or four are of a deep orange- 
red color Avhile the latter ones are nearly colorless. This coloring 
seemed to be constant in all the living specimens examined. The 
species is cosmopolitan.

This is the most common species of the genus in this region. It is 
widely distributed and of good size so that it is usually one of the first 
species to be singled out in looking over a dredge haul for Forami- 
nifera. Frequently it is found in almost pure sand from the deeper 
parts of Vineyard Sound, where it is often the only species of Fora- 
minifcra dredged. Some of the specimens in general appearance 
approach Polymorphiua ohhnga and P. compressa, but connecting 
forms with the typical P. lactea are usually present.
