Î In seventeen specimens, in which the rostrum is complete, the numbers of teeth are as follows :— 2 go ZOOLOGY OF THE FAR EAST. inferred, as has been done by Bouvier, that they were altogether absent. In thecomparatively short series of specimens before me the lower margin bears from i to 4very small teeth in its distal third ; it is therefore not improbable that it is Fig. 12.—Caridina serrata, Stimpson. a.

The preorbital length of the antennular peduncle is only about half the postorbitallength of the carapace. The lateral process of the basal peduncular segment is long,much as in C. serratirostris, de Man, reaching a little beyond the end of the segment towhich it is attached. In lateral view the distal end of the second segment of the antennular peduncle is Dorsal specimen has 5 teeth. 3 .specimens have 92 ,, ,, 10 5 ,. ,. 1 specimen has 12 2 specimens have 13I specimen has 14 Ventral eeth. 2 specimens have i ,, .,2 „ ..3 „ 3 .. ..4 ,, Crustacea Decapoda and Stomatopoda. 291 produced to a tooth at its infero-external angle.
