shape and armature of the propodus, etc. It is remarkable for the 
great size of the eggs, which appear not to be carried in masses, 
but are scattered over the accessory legs. 
Taken by the IT. S. Fish Commission, in Vineyard Sound, in 1871, 
on the stems of Pennaria tiarella ; and in 1874, at Noank, Ct., in the 
harbor on muddy bottom. Several specimens were taken, in 1874, by 
Professor S. I. Smith, from tubularian hydroids growing on the 
bottom of an old ship, at Noank, Conn. 
Pseudopallene Wilson. 
Body robust ; neck broad and thick ; rostrum more or less acute. 
Antennae three-jointed, chelate ; palpi wanting ; accessory legs eleven- 
jointed; legs stout and comparatively short, daetylus without auxili- 
ary claws. 
This genus has hitherto been confounded with Pallene , and some 
confusion has thus been caused in the diagnosis of that genus. 
In Pallene , as described by Johnston (Mag. Zool. and Bot., vol. i, 
p. 380) the accessory legs are nine-jointed ; the neck is constricted 
and more or less elongated as in Nymphon ; the rostrum is short and 
nearly hemispherical ; and the daetylus bears two very large auxiliary 
claws. The presence or absence of these claws is a good generic 
character ; they are always two in number, are movably articulated 
to the daetylus, and are provided with a special set of muscles by 
means of which they are moved. It is to be observed, also, that the 
peculiar spines upon the outer joints of the accessory legs in Pallene 
are very unlike those of Pseudopallene. 
Kroyer figures three species of “ Pallene” in Gaimard’s Voy. en 
Scand., Laponie, etc. (P. discoidea , P. intermedia and P. spinipes). 
The first of these is undoubtedly a Pseudopallene , and probably also 
the other two, but, not having examined specimens of them, I have 
been unable to verify this.
