the Mediterranoau and is found along the Atlantic coast of Europe 

 as far up as 8aint-Jean-dc-Luz (Basses-Pyreneea) : the latter, which 

 aj)parontly ought to be regarded us an iusular form, and was 

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

 at Fayal, Flores, and Rosario de Corvo in 1888 (third and fourth 

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

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

 rous colony of ll>fale Grimaldii 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 anteunte and legs violaceous pink, the eyes black. 



Platophium (Ci/rtophiu)))) cheloiophil xm, doficnhed from the nume- 

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

 with except upon turtles. The ' Cliallenger ' expedition ca])tured a 

 single specimen of the species, a young one, upon a CJuhntia imbn- 

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

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



The very numerous examples of Caprella acutifro)is (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 Xorth Atlantic, the Pacific Ocean 

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

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

 Lepas and Hj'droids, except a female which was obtained upon a 

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



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

 common in the Mediterranean. It has been reported from the 

 Adriatic (IJcUer) and the Azores (21i. Barroin). 



Lepas Jldli and Conchoderma virrjatum do not give rise to any 

 special remark. The second of these Cirripedes belongs to the 

 variety chelonopJiilum, Leach. 



Platylepas bissexlobata, wliich 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 Jiendus, t. cxvi, no. (Feb. 27, 18*J3),

 ;^9=' 41' 35" N. and long. 33° 24' 22" W., during the fourth expedition of

t The locality is not indicat»-d, but it is probable tliat it is the most 

 southerly of tliose where P. clielonophilum has been taken, considering 

 the habitat of C'helonia imhricata.
