ZOOLOGY OF THE FAR EAST. 
Tribe PAGURIDEA. 
Family PAGURIDAE. 
Subfamily PAGURINAE. 
Genus Clibanarius, Dana. 
Clibanarius padavcnsis, de Man. 
1888. Clibanarius padavensis, de Man, Journ. Linn. Soc, XXII, p. 242, pi. xvi, fig. i. 
Three specimens were found by Dr. Annandale at the mouth of the Prai River, 
opposite Penang, on mud- flats exposed at low water. They were living in Murex 
and other marine shells. 
Clibanarius longitarsis (de Haan). 
1887. Clibanarius longitarsis, de Man, Arch. f. Naturgesch., I^II, i, p. 441. 
This species was very abundant at Kaw Deng and in other localities near the 
mouth of the Tale Sap. All the larger individuals were inhabiting marine shells, but 
very small ones were usually found in Potamides fluviatilis. Dr. Annandale noted 
that the legs in living specimens were very deep blue with bright blue longitudinal 
stripes and that the eyestalks were bright olivaceous brown. 
Genus Diogenes, Dana. 
Diogenes avarus, Heller. 
1905. Diogenes avarus, Alcock, Cat. Indian Decap. Crust., II, fasc. i, p. 68, pi. vi, fig. 6. 
Two very small specimens, dredged in the outer part of the Tale Sap, opposite 
Singgora, appear to belong to this species. 
Tribe THALASSINIDEA. 
Family CALEIANASSIDAE. 
Subfamily UPOGEBIINAE. 
Genus Upogebia, Leach.

1915. upogebia (Upogebia) heterocheir, Kemp, Mem. Ind. Mus., V, p. 257, pi. xiii, figs. 6, 7. 
Two specimens were dredged towards the northern part of the channel connect- 
ing the inner and outer parts of the Tale Sap near Pak Payum at depths of to 5^ 
metres. They were taken in a thin layer of soft mud overlying a bottom of coarse 
sand in water of specific gravity 10015 (corrected). 
One of the specimens is very much damaged ; the other is a male approximately 
16 mm. in total length. In this specimen the first peraeopods differ from those of the 
types in the absence of the subterminal tooth on the upper edge of the merus and in 
the presence of only one tooth on the upper border of the propodus. The extent of
