1626 THE VOYAGE OF H.M.S. CHALLENGER. 



" Die Dornenlosen unterscheiden sich namlich von den niit Dornen auch durch die Form der 

 Augen, welche bei den Letztem deutlich nierenfb'rinig, bei den Erstern oval sind. Dieser 

 Cbarakter ist so constant, dass man von der Form der Angen auf das Vorbandensein oder 

 Feblen der Dornen und umgekebrt schliessen kaun. Es gibt aber aucb Individuen bei 

 welcben die Dornen sebr scbwacb ausgepragt sind, ja sogar nur ein einziger ganz scbwaeber 

 Dorn vorhanden ist. 



" Diese Uebergangsformen sind wobl geeignet, die vielleiebt unrichtige Benennung und Unter- 

 seheidung von Gamm. puteanus fossarum und pulex Kocb — dahin zu berichtigen, dass bios 

 Gamm. pulex Fabr. niit der Varietat spinosus beizubebalten sei." 



From tbe reference bere given to Dr. Cornel Chyzer, it may be surmised that he takes notice of 

 some fresh-water species of Gammarus in his work " Ueber die Krustaceenfauna Ungarns. 

 Verhandl. des Zool. Bot. Vereines 1 858," which is mentioned in a bibliographical list by 

 Dr. Anton Fric.

Notes on the Zoology of the last Arctic Expedition under Captain Sir F. L. 

 M'Clintock, R.N. [Read Friday Evening, April 27, I860.] The Journal of the 

 Royal Dublin Society. Vol. III. 1860-61. Dublin, 1862. pp. 61-77. 1 



An introductory observation states that, " with a very few exceptions, none of the species of 

 birds, fishes, mollusca, Crustacea, and insecta are strictly confined to the Arctic regions." 

 The Amphipoda are recorded as follows on page 68 : — ■ 



" 1 1 Gammarus loricatus (Sab.). — Numbers found swimming about in Port Kennedy. 



" t + Gammarus locusta (Mont.). — Associated with the former and following species at Port 

 Kennedy. 



" t + Gammarus boreas (Sab.). — Ditto. 



"ft Amphitoe Edwardsii (Sab.). — Near Cape York, 15 fathoms. 



" f % Amphitoe Sabini (Leach). — Caught in a garbage net in numbers at Port Kennedy. 



"ft Acanthosoma hystrix (Owen). — Near Cape York, 15 fathoms. 



" ± Lysianassa vahlii \ 



.. , . r . j- 7 j > (Kroyer). — Found at Port Kennedy, 



t + Lysianassa appendirmata ) v J ' J 



" X Stegocephalus ampidla (Kr.). — Two very fine specimens obtained at 10 fathoms in Port 

 Kennedy. 



" t + Themisto Arctica (Kr.). — Found in tbe stomach of a seal at Port Kennedy." 



" Specimens of species marked thus f are deposited in the Museum of the Royal Dublin Society. 

 Specimens of species marked thus % are deposited in the Queen's College, Belfast." 



Page 69 contains " a comparative table, showing the number of crustacean species brought home 

 by the several expeditions under Parry, Ross, Penny, Belcher, and M'Clintock." Seventeen 

 species of Amphipods are named, including besides those already mentioned, " Gammarus 

 Sabini (Leach)"; "G. Kroyeri (Bell)"; "G. nugax (Fabr.)," said in a foot-note to be "now 

 usually referred to genus Lysianassa " ; " Amphitoe Jnrinii (Kr.) " ; " A. Ixviusculx (Kr.) "; 

 "Lysianassa sagenx (Kr.)"; " Metoeeus Cyanex (Sab.)." Gammarus sabini (Leach) and 

 Amphitoe sabini (Leach) are both of them credited to Ross' Second Voyage and to Penny's, 

 while the two names are divided between the other voyages, Parry's first and second and 

 Belcher's receiving Gammarus sabini and M'Clintock's the synonymous Amphitoe sabini. 

 Lysianassa apipendiculata is attributed only to M'Clintock's voyage, and to that with a note 

 of interrogation.
