878 Miscellanea Zoologica. 



the hinder pair of legs is an erect cylindric tubercle, which in some 

 point of view might be mistaken for a tail ; the summit of this is 

 furnished with two minute spines : legs long, slender, spinous." — 

 " Length of the body 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 : rostrumjel- 



* 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. 

 f Orithyia — " Dilectaque diu caruit Deus Orith'ia, 



Dum rogat, et precibus mavidt quam viribus uti." 



Ovid. Metam. lib. vi. fab. 8, 



" flerunt Rhodope'iae arces, 



Altaque Pangaea, et Rhesi Mavortia tellus, 

 Atque Getas, atque Hebrus, et Actias Orythia." 



Virg. Georg. hb. i.v.
