the hinder pair of legs is an erect cylindric tubercle, which in some 
point of view might be mistaken for a tail j the summit of this is 
furnished with two minute spines : legs long, slender, spinous.". 
" Length of thebody a quarter of an inch. Colour rufous-brown. 
" The female is furnished with] a- pair of long jointed appendages, 
which originate at the fore part of the thorax, and turn underneath, 
as described by the figure. The use of these antennae-like mem- 
bers is for holding and carrying about their eggs." Montagu. 
Dr Leach, after his brief notice of this species, adds, " Two spe- 
cimens, which were most obligingly communicated by R. Steven- 
son, Esq. from the Bell-rock Lighthouse, on the Scottish coast, in a 
living state, were of a blood-red colour, and are possibly distinct." 
And after his character of the genus in the Linnaean Transactions 
he appends the observation " species multas indigenas possideo, at 
characteres nondum elaboravi." Leach. 
The Phoxichilus spinipes of Lamarck, Anim. s. Vert. v. 75, is a 
sadly confused species, which it will be found impossible to deter- 
mine by the most zealous commentator.*

DESCRIPTION. Animal araneiform, slender, of a uniform fine 
clear red colour, with the joints of the legs and tarsi yellowish, and 
when magnified a central vessel, distinguished by its deeper tint, is 
seen running uninterruptedly through the body and legs : rostrum yel- 
* Lamarck's definition of his " Phoxichilus" is the same as that which I 
give of " Orithyia," but I could not retain the former name, having applied it 
to an emandibulate species, after the example of Leach. Some have erroneous- 
ly described the Phalangium spinosum of Montagu with a pair of palpi, mistak- 
ing the oviferous legs for such, a mistake which has originated from consult- 
ing the figure without reference to the description.
