species to be looked for in the littoral zone In any part of the North 
Atlantic. 
Biloculina ringens var. striatella, var. nov. 
Plate 5, fig. 1. 
Like the typical in general contour, the margin of the outer chamber 
somewhat irregular especially near its base, the surface with numerous 
delicate longitudinal channels or striations. 
In the material scraped from the wharf piles this variety was often 
abundant while no true Biloculina ringens was obtained as a rule 
from this sort of material. It is somewhat like var. siriolata Brady 
described from xVustralian waters but differs from that variety in the 
form and striations. It is very different from Biloculina comata which 
is foimd in comparatively deep water. 
Biloculina eloagata d'Orbigny. 
Plate 5, fig. 7-9. 
BilocuHna eJongata d'Orbigny, '26, p. 298, no. 4; Brady, '84, p. 144, pi. 2, 
fig. 9, a, b; Flint, '99, p. 294, pi. 39, fig. 4. 
Specimens of this species were found in considerable numbers 
among hydroids and scrapings from the piles of the dock at Woods 
Hole. Occasionally the species is met with in the dredgings. It may 
be distinguished from Biloculina ringens both by the shape of the 
aperture and by the general form. 
Biloculina tubulosa Costa. 
Biloculina tubulosa Costa, '56, p. 309, pi. 24, fig. 7; Brady, '84, p. 147, 
pi. 3, fig. 6, a, b, c; Flint, '99, p. 293, pi. 39, fig. 1. 
This species occurs rather frequently throughout the region. The 
deep groove at the side of specimens of this species varies somewhat 
but not greatly. It was found most fi-equently in the deeper waters 
of Vineyard Sound. 
Miliolina seminulum (Linne). 
Plate 5, fig. 2. 
Serpula seminulum Linne, 1767, p. 1264, no. 791. 
Miliolina seminulum Williamson, '58, p. 8.5, pi. 7, fig. 183-185; Brady, 
'84, p. 157, pi. 5, fig. 6, a, b,^c; Flint, '99, p. 297, pi. 43, fig. 2. 
This species is very abundant throughout the region. It was
