ortmann: tertiary invertebrates.

Affinities: In general form and sculpture this species is closely allied 
to A. semistriatus (Fer.) (Hoernes, 1856, p. 507, pi. 46, f. 22, 23), Mio- 
cene, Europe. 
Fam. BULLIDAd Pilsbry. 
Gen. BULLA Klein. 
172. Bulla remondi Philippi. 
PI. XXXVII, Fig. 7 a '\ 
1887 B. r. Philippi, Tert. & Quart. Verst. Chiles, p. 109, pi. 13, f. 7. 
1899 B. r . Ortmann, in: Amer. Journ. Sci., v. 8, p. 431. 
Shell subcylindrical. Apex deeply umbilicated, funnel-shaped, with 
blunt edge, whorls hidden. Whole surface covered with fine, spiral, im- 
pressed lines. Mouth elongate, narrow above, not produced upward, 
dilated below the middle. 
Height, 13 mm; diameter, 5 mm. 
Remarks : The measurements given by Philippi in the text (p. 109) do 
not agree with his figure, but would indicate a much thicker shell (height, 
19 mm; diameter, 9 mm; rel. 2.1:1), while his figure is: Height, 21 
mm; diameter, 8 mm; rel. 2.6:1, which agrees well with our specimens, 
although the latter are much smaller. 
Philippi says that there is a fold on the columella; I do not see it, but 
the preservation of our specimens (filled with and imbedded in hard 
matrix) does not permit a closer investigation. Philippi figures no fold. 
B. chilensis d’Orb. (Philippi, 1887, p. 109, pi. 13, f. 23), from Port 
Famine (supposedly Cretaceous) somewhat resembles this species, but it 
is broader and shorter and the spiral lines are wanting in the lower part 
of the shell. 
B. patagonica v. Ih. comes very near in form, but the spiral lines are 
distinct in the lowor part of the shell and indistinct or wanting in the 
upper part. 
B. triticum Philippi (1887, p. no, pi. 13, f. 9) from Navidad has also 
a similar outline, but is distinguished at once by the sharp angulation on 
the apical part, the latter being only slightly concave, not funnel-like.
