SHELLS FROM THE MOLUCCAS. 153 
At last should be mentioned another variety from the 
same locality, which, according to Prof. v. Martens, belongs 
to his var. fulminata, but is smaller; the aperture in the 
specimens collected by Martin is more rounded than that 
of any of the preceding varieties, the peristome is brownish ; 
its measurements are: 
diam. maj. 21—22, min. 17—18, alt. 9—9!/, ; apert. lat. 
[10'/,—11, alt. 10 mill. 
9. Pythia scarabaeus Linn. 
Pfeiffer, Mon. Auric. p. 82. 
A few specimens from Aboro, Haroekoe, collected by 
Baron van Hoëvell, varying in colour and shape, as 
recorded by nearly every author on this genus. One 
specimen is yellowish white, with only very few brown 
spots. Martin collected one specimen on Saparoea and 
another at Hatoesoea, Ceram; this last specimen has the 
umbilicus nearly closed. 
10. Pythia semisulcata A. Adams. 
Adams, Proc. Zool. Soc. London, 1850, p. 151. 
From this species a few specimens were collected by 
Baron van Hoévell along with the preceding Pythia; as I could 
not determine it, I asked the assistance of Prof. Boettger of 
Franckfort, who identified it as semisulcata Ad. The specimens 
agree with the description of Adams, but the measure- 
ments differ considerably from those given by Dr. Pfeiffer 
(Mon. Auric. p. 93), the largest specimen having a total 
length of 32 mill., the diam. maj. is 20, diam. min. 151/, 
mill. (in Pfeiffer's Monograph 27: 14:11). One specimen 
is nearly white, the other ones vary in colour and in the 
umbilicus which is more or less large. 
Two young specimens from Saparoea, collected by Martin, 
seem to belong to the same species.
