MARINE CRUSTACEANS. 689 
Genus Micippa Leach, 1816. 
20. Micippa philyra (Hbst.), 1803. Alcock, 1. p. 249. 
Taken on the reef at Hulule, Male Atoll, and dredged in Kolumadulu, South Nilandu, 
Fadifolu, Suvadiva and North Male Atolls in 20—35 fathoms. 
21. Micippa margaritifera (Hend.), 1893. Alcock, 1. p. 253. 
Dredged in Suvadiva Atoll in 43 fathoms. 
22. Micippa parca Alc., 1895. Alcock, 1. p. 253. 
I think that this form should have specific rank, rather than that of a variety of 
M. margaritifera, given to it by Alcock. 
Dredged in 20 and 25 fathoms in Mahlos and South Nilandu Atolls respectively. 
Genus Macrocoeloma Miers, 1879. 
23. Macrocoeloma nummifer Alc., 1895. Alcock, 1. p. 255. 
Almost all the spines on my specimens end in a round knob. Alcock does not mention 
this, but such knobs were present on several of the spines in the individual he figures. 
In my specimen thickenings of a like kind are set on the tips of the front. Alcock’s 
figure, however, shows none. The knobs cannot be rubbed off and do not seem to be due 
to foreign growths of any kind. 
The species was dredged in 30 fathoms in South Nilandu, and in 23 fathoms in 
Mahlos Atoll. 
Family Parthenopidae. 
Subfamily Parthenopinae. Genus Lambrus Leach, 1815. 
24. Lambrus (Rhinolambrus) bispinosus Rathb., 1902. 
Lambrus (Rhinolambrus) bispinosus, Rathbun, Bull. Mus. Harvard, xxx1x. 5, p. 134, 
figs. 1, 2. 
In her description of this species, Miss Rathbun says that the upper side of the hand 
bears two lobes. Later she says that the species is separated from JZ. confragosus (among 
other differences) by the presence of only one lobe in this position. Her figure and my 
specimens bear out the latter statement. 
Dredged in South Nilandu Atoll in 25 fathoms. 
25. Lambrus (Rhinolambrus) pelagicus Riipp., 1830. Alcock, 1. p. 267. 
The granules on the back are quite well marked in my specimens, as in Milne-Edwards’ 
figure (Now. Arch. Mus. vit. Pl. XIV. fig. 4). It would seem that Alcock had found in 
the Andamans local races both of this species and of ZL. gracilis, im which the granules 
were reduced in size and distinctness. 
Dredged in Mulaku, Suvadiva, and Addu Atolls, in 28—43 fathoms.
