the Mediterraneau and is found along the Atlantic coast of Eurojje 

 as far up as Saiut-Jean-de-Luz (Basses-Pyrenees) ; the latter, which 

 apparently ought to be regarded as an insular form, and was 

 obtained for the first time by one of us at Fayal in 1887, and then 

 at Fayal, Plores, and Eosario de Corvo in 1888 (third and fourth 

 expeditions of the ' Hirondelle '), was met with again during the 

 voyages of the ' Melita ' in the Canaries and in Corsica. The nume- 

 rous colony of Hyale Qrimaldii attached to the second of our turtles 

 comprised adult males, oviferous females, and young individuals of 

 all ages. Their colour was noted down at once ; the body is orange- 

 brown, the antennae and legs violaceous pink, the eyes black. 



Platopliium {Qyrtopliium) chelonopldlum, described from the nume- 

 rous specimens obtained by the * Hirondelle ' *, has never been met 

 with except upon turtles. The ' Challenger ' expedition captured a 

 single specimen of the species, a young one, upon a Chdonia imhri- 

 cata, L., from the Atlantic f. An adult female was found upon the 

 first of our Thalassocliehjs and an adult male upon the second. 



The very numerous examples of CapreUa acutifrois (comprising 

 adult males and females and young of all sizes) belong to the well- 

 characterized variety described by M. Mayer under the name forma 

 Andrea}, which appears to be exclusively pelagic. This form may 

 be said to be of universal distribution ; specimens of it are known 

 from the Gulf of Naples, the North Atlantic, the Pacific Ocean 

 (voyage of the ' Galathee '), the Sea of Japan, and the Strait of 

 Corea, all of which were found upon wreckage in company with 

 Lepas and Hydroids, except a female which was obtained upon a 

 turtle in lat. 38° 10' N. and long. 61° 20' W. 



Tanais Cavolinii, on the contrary, is a littoral species, which is 

 common in the Mediterranean. It has been reported from the 

 Adriatic {Heller) and the Azores {Th. Barrois). 



Lepas Hilli and Conchoderma virgatwn do not give rise to any 

 special remark. The second of these Cirripedes belongs to the 

 variety clielonoph'dum. Leach. 



Platylepas hissexlohata, which was mentioned by Bivona as long 

 ago as 1832 as occurring upon the turtles of the Mediterranean, 

 does not appear to have been noticed there again. It is, however, 

 although it seems to have been seldom observed, a species of world- 

 wide distribution. Darwin considered it to be identical with that 

 which is found upon the manatees of the tropical Atlantic and upon 

 the dugongs of Australia. Perhaps it may even occur on the shores 

 of California. — Comptes Rendus, t. cxvi. no. 9 (Feb. 27, 1893),

 pluum chelonophilum, commensal de Thalassoclielys caretta, L." ('Comptes 

 riendus,' Feb. 27, 1888). A turtle belonging to the same species, cap- 

 tured on Aug. G, 1888, in the neighbourhood of the Azores, in lat. 

 39° 41' 35" N. and long. 33° 24' 22" W., during the fourth expedition of 

 the * Hirondelle,' likewise furnished a very large number of P. chelono- 

 philum. 



t The locality is not indicated, but it is probable that it is the most 

 southerly of those where P. chelo7iophilian Las been taken, considering 

 the habitat of Chelonia imhricata.
