[Lepeophtheirus olwurug, Bassett-Sraith. Mi*. Bassett- 

 Sinith (Jour. Marine Biol. Assoc. vol. iv. 18%, p. 157) 

 records a species from the Brill (.Rhombus Icei'is') taken at 

 Plymouth, and refers it with doubt to Lepeophtheirus 

 obscurus, Baird, which was obtained from the same species 

 of fish. Subsequently Bassett-Smith figures what he then 

 styles Caligus obscitrus, Baird (Ann. & Mag. Nat. Hist. 

 ser. 6, vol. xviii. pi. iv. fig. 2), and not only is his parasite 

 there referred to the genus Caligus, but the figures show the 

 presence of sucking-disks. Whether the form he found was 

 a Lepeophtheirus or a Caligus, it was certainly not Lepeo- 

 phtheirus obscurus of Baird. In Bassett-Stnith's third paper 

 (Proc. Zool. Soc. 1899, p. 45G) he referred it back again to 

 the genus Lepeophtheirus. It is just possible, if the species 

 he found was a Lepeophtheirus, that it may have been the 

 female of L. appendiculatus, Kroyer, male (Naturhist. 

 Tidssk. ser. 3, I8t>3, p. 207, pi. vi. fig. 4, a-?'), which has a 

 branched furcula, but the former was taken on the Brill, 

 while the latter was found on Raia clavataJ]
