294 MR. BELL, HORÆ CARCINOLOGICÆ ; 
in fact scarcely intelligible. It is a remarkable and interesting form, and in its orbieular 
outline resembles two new species which are in my collection, from the Western Coasts of 
America. It differs from all others of the genus in having a tooth or produced tubercle, 
on each side, on the margin of the carapace. 
PERSEPHONA ORBICULARIS, mihi (Tas. XXXI. fig. 7 ). Testa orbiculari, angulo pterygo- 
stomiano in tuberculo abrupté producto; spinis posticis æqualibus, angulum fer& 
rectum designantibus. | 
Hab. ad Valparaiso. Mus. Bell. 
Carapace orbicular, the latero-anterior margin slightly waved, the regions rather 
distinct, surface somewhat punctate, with numerous minute granules, which are more 
thickly crowded on the lateral margin and on the posterior portion; the front with a 
very slight triangular notch; pterygostomian angle produced into a distinet tubercle; 
the three posterior spines short, acute, recurved, the upper one forming with the two in- 
ferior almost a right angle. External pedipalps with the stalk erooved longitudinally, 
and in the female the inner grooved portion separated from the outer by a ciliated ridge. 
Anterior legs, with the arm, wholly tubereulated, the wrist granulated; fingers the length 
of the arm. Abdomen (female) with the first three segments, and the base and margin 
of the shield, tuberculated. 
The colour is dull yellowish, regularly mottled with dull and pale red. 
Length of carapace 1:5 in. 
The only specimen I am acquainted with of this species is a female, which was brought 
from Valparaiso by Mr. Miller, Surgeon R.N., and is in my collection.

Hab. ad insulas Galapagos. Mus. Bell. 
Carapace nearly orbicular, somewhat produced and narrowed anteriorly, minutely 
punctate, covered, excepting at the anterior portion, with very small distinct granules, of 
which a distinct line borders the latero-anterior portion ; the anterior margin waved, the 
pterygostomian angle obsolete, marked only by a slight elevation. Front broad, slightly 
emarginate; lateral and posterior margin much rounded, the spines placed in nearly a | 
right-angled triangle, nearly equal, recurved at the apex. Anterior legs with the arm 
everywhere tuberculated, the wrist, slightly granulated on the inner side, the hand mi- 
nutely punctate. External pedipalps as in P. orbicularis. Abdomen (female) slightly | 
granulated at the posterior and lateral portions. | 
Colour pale buff. 
Length of carapace 1-3 in. ro 
Of this species two specimens were brought by Mr. Cuming from the Galapagos. They 
were dredged in córal sand at 6 fathoms, i 
I have dedicated this species to my friend Professor Milne-Edwards.
