The antenna, second gnathopods, and fifth peraeopods of the two species named in the title are 

 compared, with illustrative figures, the conclusion being that the specific distinction of the 

 two forms should be maintained.

Sur un Amphipode nouveau (Cyrtophium chelonopkilum), commensal de 



Thalassocnelys caretta L. 4 pages. 



The chelonian was captured in the waters of the Azores, between Pico and San Jorge, and 

 yielded seventy-seven specimens, male, female, and young, of the Amphipod. The authors 

 say, " Cette espece differe bien nettement des formes deja. connues du meme genre par la 

 brievete de ses antennes. Elle se rapproche de C. Ixve Heller par l'aspect lisse de la partie 

 superieure du corps ; mais, en dehors du caractere mentionne ci-dessus, sa tete tres courte 

 et la forme de ses gnathopodes ne permettent pas de la confondre avec l'espece de 

 l'Adriatique." They consider Haswell's genus Dexiocerella a synonym of Cyrtophium, and, 

 since Cijrtophium Iseoe is preoccupied, they give to Haswell's species of that name the new 

 title "Cyrtophium Haswelli." They notice that Cyrtophium tuberculatum of the British 

 Museum Catalogue ought to resume the name " Lsetmatophilus tuberculatum Bruz.," and 

 that " C. armatum Norman " is certainly also a Lsetmatophilus. On Dej-iocerella see p. 566.

Sopra le glandole glutinifere e sopra gli occhi degli Anipeliscidi del Golfo di

In Ampelisca, it is stated, there are many large gland-cells in the connective tissue of the 

 thoracic region ; the side-plates of the gnathopods and first two pairs of peraeopods are 

 glandular, with ducts opening on the lower margin ; in the first two pairs of peraeopods 

 moreover all the joints are glandular except the long awl-shaped finger, which has openings 

 in its walls for the emission of the cement ; in the fifth peraeopod the excretory ducts 

 from the gland-cells of the upper joints lead to little openings arranged along the front 

 margin of the two terminal joints. It is no doubt to these series of duct-openings that I 

 have referred in the description of Ampelisca dbyssicola, p. 1051, and of Ampelisca fusca, 

 p. 1056, without knowing their true meaning. Professor Della Valle mentions that Hoek 

 had already noticed the glandular apparatus in Ampelisca, but it was observed still earlier 

 by S. I. Smith. See Note on the latter author, 1874 (p. 432). 



In Haphxips the gland-cells are said to be found in the side-plates and in the first l and third 

 joints of the first gnathopods, not in the side-plates but in the first four joints of the second 

 gnathopods, in the side-plates and first three joints of the first two pairs of peraeopods, and 

 to a small extent in the first joint of the fifth pair, while in the interior of the body, both 

 peraeon and pleon, the cement^producing apparatus attains a very great development the 

 1 Or second and fourth, as Professor Della Valle numbers them.
