MARINE CRUSTACEANS. 687 
Subfamily Pisinae. Genus Nazioides A. M.-Edw., 1865. 
The synonymy of this genus is discussed by Rathbun, Proc. Biol. Soc. Washington, XI. 
p. 157 (1897). 
7. Nasioides hirta A. M.-Edw., 1865. 
Nawia hirta, Alcock, loc. cit. p. 218. 
Taken in Kolumadulu, Suvadiva, Haddumati, and South Nilandu Atolls in 30—40 fathoms. 
8. Nawioides spinigera, n. sp. (Pl. XLVII. fig. 3). 
Diagnosis: “A Nasioides with the horns more than half the length of the body, bearing 
the accessory thorn a third of their length from the end; the body hairy, with many knobs 
and thorns, of which the largest are three in a row on the gastric region, two on the 
cardiac, one on the intestinal, three in a triangle on the branchial, with one in front of 
them, and one on each eye-hood, these latter being quite upright, but bent slightly forwards 
at the tip, no thorn at the angle of the mouth, two knobs on the pterygostome, two 
thorns on the outside of the basal joint of the antenna; the chelipeds slender, little longer 
than the body, the fingers half the length of the palm, finely toothed and meeting along 
nearly their whole length, a spine at the end of the arm; and the walking legs slender, 
the first pair very long, a long spine at the end of the meropodite of this limb, a short 
one on the next, and none on the hinder two.” 
Length: 11 mm. Breadth: 8mm. Colour in spirit: white. 
Allied to NV. cerastes (Ortm.), 1894. 
Three males dredged in 30 fathoms in North Male Atoll. 
Genus Halimus Latr., 1829. 
For the synonymy of this genus, which is identical with Hyastenus White, 1847, and 
not Nawia Leach, 1828, see Rathbun, Proc. Biol. Soc. Washington, x1. p. 157 (1897). 
9. Halimus tenuicornis (Pocock), 1890. Alcock, 1. p. 215. 
The colour of this species as preserved in formalin is white with bright pink markings. 
It was dredged in South Nilandu, Male, Mulaku, Felidu and North Male Atolls in 25—30 
fathoms. 
10. Halimus gracilirostris (Miers), 1879. Alcock, 1. p. 215. 
Dredged throughout the group in 20—70 fathoms. 
11. Halimus diacanthus (de Haan), 1837. Alcock, 1. p. 210. 
Found on a black crinoid dredged in 30 fathoms in South Nilandu Atoll. 
12. Halimus calvarius (Alc.), 1895. Alcock, 1. p. 213. 
Dredged in South Nilandu, Mulaku, Suvadiva, Haddumati, and North Male Atolls in 
19—40 fathoms. 
13. Halimus convexus (Miers), 1884. Alcock, I. p. 216. 
The one specimen in the collection is a female, and differs from Miers’ (a male) in that: 
(i) the horns are less strongly divergent, (11) the palm is slenderer and the fingers much less
