In the ' Proceedings of the Zoological Society ' for 1853, p. 112, is 

 a paper by me " On the attitudes and figures of the Morse," as given 

 at various periods by different authors, with copies of some of the 

 more interesting examples, arranged in chronological order, show- 

 ing the extraordinary notions that the older naturalists had of the 

 animal. 



Sea Horses are said to be found in abundance on the seaward part 

 of the island of St. Lorenza near CaUao, mentioned in M. Bonelli's 

 ' Travels ia Bolivia,' i. 90 & 128. I have never heard of the genus 

 Trichechus living out of the Arctic Ocean, and should have believed 

 that the author had mistaken the Sea Bear (Otaria leonina) for the 

 Sea Horse, if he did not describe " the two great vrhite tusks project- 

 ing from the mouth on either side," and further observe that " the 

 tusks are of great value and form an important article of commerce" 

 (see i. 90), which cannot apply to the tusks of the Sea Bear. 



It is to be observed that the Peruvian continuation of the Antarctic 

 current runs up the shores' of Chili and Peru (see Journ. Roy. Geogr. 

 Soc. 1853) and chills that coast. This may explain why Seals are 

 found so near the tropics in these seas.
