la. Leucosia cf. unidentata de Haan; x %. Ventral view. 
1b. Leucosia cf. unidentata de Haan; x %. Dorsal view. 
2. Conus ornatissimus K. Martin; X %1. This is a form at least sub- 
specifically different from the typical C. ornatissimus of Martin. 
The notable difference is the greater width of this Pliocene form. 
3. Cardita antiquata Linneus; X 1. This form is very abundant in 
the Recent fauna of the Philippines. 
4a. Aspergillum annulosum Deshayes; X %. This very aberrant pele- 
eypod has all the characters common to the Recent species which 
was originally described from the Vizcayan seas. 
4b. Aspergillum annulosum Deshayes; X %1. 
5. Chione chlorotica, Philippi; x %4. Bureau of Science locality 1054, 
Agusan Valley, from Pliocene strata, probably equivalent to 
the Banisilan Pliocene. 
6a. Glycimeris multistriatus (Deshayes) ; X #%. In view showing hinge 
characters. This species is still flourishing in Philippine waters. 
6b. Glycimeris multistriatus (Deshayes); X 4%. 
7. Lucina cf. borealis (Linneus); x %. This species was collected 
from the Malumbang strata of Leyte, locality 2ix. Reeve reports 
L. borealis from Manila Bay, but Hidalgo states that this species 
is not reported by any other Philippine collector. 
8. Metis (2?) sp.; xX %. 
9. Ostrea sp. 
10a. Pecten leopardus Reeve; X %. Right valve. 
10b. Pecten leopardus Reeve. 
lla. Pecten exaratus K. Martin. Left valve. 
1lb. Pecten exaratus K. Martin. Right valve.

la. Pecten naganumana Yokoyama; x %. This, the type of this 
species, was described by Dr. M. Yokoyama, of the Imperial 
University of Tokyo, from the Lower Musashino formation of 
probable upper Pliocene age. 
1b. Pecten naganumana Yokoyama; X %. Convex right valve. 
2. Spondylus sp. 
3. Spondylus imperialis Chemnitz; x %. 
4. Venus squamosa Lamarck; x 5. Bureau of Science locality 1054.
