hairs, but on the inner branch, besides the short stiff 
hairs, a solitary long plumose ciliurn is attached to each 
fasciculus of hairs. 
The colour of the animal is a bluish -green, mottled 
with darker spots of the same, and on the sides, being 
permanent in position and constant in appearance, are 
several bright red or scarlet spots. These are not in the 
skin, but appear to consist of fat globules more deeply 
seated. One is situated near the infero-posterior angle 
of the second, third, and fourth segments of the body ; 
a small one also exists in the posterior lobe of the coxae 
of the three last pairs of legs, and another near the 
posterior margin of the three anterior segments of the 
tail. In the living animal they afford a convenient, and, 
as far as our experience goes, a certain specific guide. 
Under the microscope the skin is seen 
to have a granulated structure, while certain 
arrow-headed spines appear as piercing 
through some more transparent spots. Upon 
the anterior segments of the tail is a curved 
row of minute cilia, each surrounded by a 
ring, the whole enclosed by a clear areola. 
Dr. Leach, in the Edinburgh Encyclopaedia, states 
that the females carry their young about with them, 
after their exclusion. This circumstance has frequently 
been verified ; but upon the authority of our valued 
correspondent, Dr. James Salter, we are enabled to com- 
municate one of the most interesting instances of 
maternal solicitude yet recorded amongst animals so low~ 
in the scale of physical arrangement. 
Dr. Salter says, “ On catching a female with live larvae 
nothing is seen of the progeny till the parent has become 
at home in the aquarium, when the little creatures leave 
her and swim about in her immediate neighbourhood.
