to the naked eye, but really microscopically squamose); and the propodite of the swimming foot 
armed posteriorly with spinules. 
It may be added that the subspecies is much larger and wider than typical ex etastica, the largest 
male (station 3876) measuring 19 mm. long by 27.1 wide, the largest female (station 3850) measuring 
17.2 by 25.2 mm. 
The characters of the eighty specimens examined agree except that in those of medium size there 
is some variation in the size of the secondary tooth at the base of the first tooth, it being sometimes 
rudimentary, sometimes plainly developed; in large specimens it is a slender spine of good size. 
Distribution. — South coast of Oahu Island, 238 to 52 fathoms, station 3811; south coast of Molokai 
Island, 23 to 212 fathoms, stations 3838, 3847 to 3850; Auau Channel, 13 to 65 fathoms, stations 3871 
to 3876; vicinity of Kauai Island, 24 to 233 fathoms, stations 3982, 3987, 4002, 4024, 4128; northeast 
coast of Hawaii Island, 24 to 113 fathoms, stations 4057, 4061, 4062, 4063. 
Thalamita alcocki de Man. 
Thalamita alcocki de Man, Abh. Senckenb. naturf. Ges. Frankfurt a. M., XXV, 1902, 646. 
Vicinity of Modu Manu or Bird Island, 26 to 33 fathoms, station 4148, one ovigerous female, 
7.7 mm. long, 11.6 wide, fronto-orbital width 9.6 mm. 
Thalamita kukenthali de Man. 
Thalamita kukenthali de Man, Abh. Senckenb. naturf. Ges. Frankfurt a. M., XXV, 1902, 650. 
Aleunihana Channel, 176 to 49 fathoms, station 4066; one male, 8 mm. long, 11.4 wide, fronto- 
orbital width 10 mm. 
In this specimen the cardiac crest can scarcely be made out. 
This and the preceding species differ from T. exet.astica macrodonta Borradaile ( Fauna and Geog. 
Maidive and Laccadive Arch., I, 203, 1902) in having spines on the hinder edge of the last propodite.

I have not seen K. rugulosa, but to judge from the figures given by Dana and de Man (loc. cit. ), 
the carapace is more orbicular, narrower through the hepatic region, the fingers are longer and quite 
■ otherwise in shape, and there are three or four antero-lateral teeth evident behind the orbital tooth.
