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



says, " Oaprella sepfentrionalis (Squilla lobata Fubr. Fn. gr. n. 225) not only differs very 

 considerably from the CapreUa qvadrlloha (Capr. linearis Latr.) which occurs with us, in 

 the form of the second pair of hands, etc., but, so far as I can judge, is also distinct from 

 all known European species. It seems frequent in the Greenland Sea, but is not mentioned 

 by Sabine and Ross." He subsequently figures and describes CapreUa septentri<maUs, Kr,, 

 in the iSTat. Tidsskr., pp. 590-596, Tab. VIIL fig. 10-19, without reference to S'pdlla 

 lobata of 0. Fabricius. Under number 39 he says, " Gyamus Ceti (Oniscus Ceti Fabr. 

 Fn. gr. n. 230), is sent both from northern and southern districts." 



Of the species recorded by 0. Fabricius, of which Kr0yer personally knew nothing, he thinks 

 that "Oniscus arenarius (Fn. gr. n. 234)" may be a Gammarus or Ampihithoe, nna 

 " Oniscus st roemianus (Fn. gr. n. 235) " an Orchesfia, as supposed by Milne-Edwards. He 

 then mentions from English authors " Amphithoe Echcardsii {Talitrus Edwarihii Sah. 

 tab. 3. fiij. 1-4)," "Amphithoe cristata (Acanthonotus cristatus, Owen. App. to the \'oy. 

 of Ross. tab. B. fig. 8-12)," which he says seems to stand pretty near to Amphithoe Senri, 

 and " Hyper ia Cyanea (Talitrus Cyanese Sab. tab. 1, Fig. 12-18)," all which have been 

 already discussed. In a note he expresses disappointment that Owen should have left 

 Cancer boreas, Cancer ampulla and Cancer migax of Phipps without elucidation. 



In the ten orders of Crustacea, which Kr0yer here admits, he reckons that the Arctic species 

 number 68, or, taking the number of all then known Crustacea to be 1500, the Arctic 

 species furnish a proportion of about 1 to 22. In these 68, 26, he says, are Amphipods, 

 giving the large proportion of 26 out of a total of 99 then known from the world at large. 

 The total is arrived at by the combination of his own list with that furnished by Milne- 

 Edwards. It should be observed that two species of La^mipoda are here not included in 

 the number of the Amphipoda. 



Lastly, Kr0yer calls attention to the tendency in the genera Gammarus and Amphithoe, as he 

 accepted them, to develop sharp and angular forms, with horn-like processes and spines, 

 the more conspicuously the higher the latitude. As examples he adduces " Gammanix 

 loricatus, Gammarus Sahini, Amphithoe JSdioardsii, Amphithoe Hystrix, Amphithoe 

 cristata, which all extend very far within the Polar zone."

This is stated by the author to be chiefly an epitome of his previous work on the Amphipoda of 

 Greenland with very few alterations. For the three species assigned in that work to 

 Lysianassa, he now gives the name Anonyx. After the description of Ampjhithoe serrn, 

 Kr., the epitome breaks off with the notice, " continuabitur."
