and four longitudinal furrows are continued down it, arising at equal distances from the transverse 
groove ; posteriorly it is deeply notched. The whole of the thorax is of a deep fuscous colour, and 
granulate, much resembling the back of a toad. The ophthalmic peduncles are short and thick, with 
the usual spine at the base. The lateral antenna exceed the claws in length ; the moveable process 
at their base is notched along the upper part, and terminates acutely. The mesial antenna extend 
very little beyond the penultimate joint of the lateral antenna. The first joint of the foot-palpe has 
three small teeth on the outer margin, and the inner margin finely dentate ; the other joints are hirsute ; 
the flagrant extends to the base of the fourth articulation. The chela are elongated, compressed, and 
of unequal size, the right being largest: beneath they are hirsute and granulate; above they bear 
longitudinal rows of small tubercles, and reflect hues of green and gold with a metallic lustre ; a pink 
hue is also reflected in some positions. The fingers of each chela terminate gradually in points, and 
close without intervening space ; those of the left are elongated, and are bent downwards. The 
second and third pairs of claws are longer than the chela, compressed, granulate, with serrated 
margins, and together with the peduncles of the antenna reflect the same hues as the preceding pair; 
their ultimate joints are twisted as in Pag. Streblonyx . The fourth and fifth pairs of claws are very 
diminutive, and are hirsute at the extremity, but are unprovided with the dark-coloured rough plate 
which is observable in some species of Pagurus. The abdomen is shorter in proportion to the body 
than in most of this genus ; it has a transparent oval horny plate on each side, near its connection with 
the thorax, but is without any lateral laminae, or ciliated appendages ; at least there was no appearance 
of any in the three specimens from which the preceding characters were taken ; but this circumstance 
may be peculiar to the males. 
Kamtschatka is indicated as the habitat of this species.

A single specimen of this species was taken at Whitsunday Island by Mr. Lay, who has given the 
following note respecting its habits. “This specimen breathes water only, and dies very soon after 
being removed from that element.”

This specimen was captured at Carysfort Island. 
The appendages of the post-abdomen in this specimen are situated on the left side, and are five in 
number; the three first are flagelliform, consisting of a stem or handle half an inch in length, from 
the extremity of which proceed three longer curved processes, provided with very fine hairs. The fourth 
appendage is a conical process from the side of the abdomen, the apex of which is elongated and 
hirsute : this may be accidental, for I have seen nothing analogous to it in any other species, and it is 
not noticed by Olivier, or Quoy and Gaimard. The fifth appendage is small, and consists only of two 
joints, the last being simple and ciliated. The whole of the under part of the abdomen has the 
roughened character which Mr. Broderip has ascertained to arise from the presence of numerous 
minute acetabula.
