Capt. Fielden refers to the feeling of disappointment 

 expressed by Mr. Smith and Dr. Jeffreys and points out that they 

 did not take into consideration the fact that the species were 

 truly arctic and did not include collections made in Davis' Straits 

 and Baffin's Bay. Capt. Fielden believes that species thinning out 

 northwards his collections fairly represent the fauna of the extreme 

 north. He discusses the causes of the absence of mollusca in 

 the northern seas, and gives a table of the number of species 

 collected by various expeditions, in which the "Valorous" figures 

 for 122, Belcher for 45, Hayes for 21 and Fielden for 35, the 

 respective latitudes being 60° — 70°, 75° — 77°, 78° — 79°, 79° — 

 82° 30' North.
