46 SCLATER. BIRDS OF GREENLAND. 



(4.) The habits of the species that are found nesting, that is, as 

 regards the date and the mode of their nesting, and its continuance. 

 Species specially requiring attention are — 



1. The Rock-ptarmigan (Manual, p. 100), in order to ascertain 

 its specific distinctness from Lagopus mutus. 



2. The Grey Plover (1. c, p. 101), of which the eggs are 

 scarcely known to collectors. 



3. The Sanderling (1. c, p. 102), of which " authentic eggs " 

 are " very rare." 



4. The Grey Phalarope (1. c, p. 102), of which " the breeding 

 " habits are little known." 



5. The Knot (1. c, p. 103), of which the nidification is *' not 

 " known with any certainty." 



6. The Sabine's Gull (1. c, p. 105), of which the eggs are 

 " extremely rare." 



7. The Cuneate or Ross's Gull, of the breeding-habits of which 

 " nothing whatever is known," and of which specimens are ex- 

 ti'emely scarce in collections. 



8. The Puffin of Greenland (1. c, p. 108), in order to ascer- 

 tain to which form, Fratercula glacialis or F, arctica, it really 

 belongs. 



For the further information as regards desiderata, Professor 

 Newton's concluding observations in his above-mentioned article 

 should be attended to. 



4. Instructions for making Observations on, and 

 Collecting Specimens of, the Fishes of Greenland. 

 By Dr. Albert Gunther, F.R.S. 



The information on the Fishes of Greenland is scattered through- 

 out the zoological literature ; and the treatises in which an attempt 

 at giving a general account of this fauna has been made, are very 

 imperfect and antiquated. Yet the following publications may be 

 consulted with advantage : — 



1. Richardson, J. " Fauna Boreali- Americana." Part containing 

 the Fishes. 4to., 1829. 



2. Richardson, J. Account of the Fish, in Belcher's " The Last 

 of Arctic Voyages." Vol. ii. 



3. Reinhardt, J. " Ichthyologiske Bidrag til den Gronlandske 

 Faumj," in Danske Videnskabs Selsk. naturvid. og mathem. 

 Afhandl." Vol. vii. 



4. Gaimard, P. " Voyage en Islande et au Gronland, execute 

 pendant les annees 1835 et 1836 sur la corvette ' La Recherche.' " 

 Paris, 1851. 8vo. Atlas in folio. 



5. Gaimard, P. "Voyage en Scandinavie, en Laponie, au 

 Spitzberg et aux Faroe, pendant les annees 1838, 1839, and 1840, 

 sur la corvette 'La Recherche.'" Atlas foL, Paris. 



Thus, the Naturalists cannot fail to add considerably to our 

 scanty knowledge of this fauna, and to the still more imperfect 

 materials in British collections.
