Dr Moore announced his having procured a fish in Plymouth 

 Harbour, new to Great Britain, the Trigla cataphractes, and Mr 

 Yarrell confirmed the accuracy of the observation, and stated the 

 species to be common in the Mediterranean. 



Dr Richardson then read the concluding portions of his report. 

 The order Edentata is eminently South American, and only three 

 or four species are met with in North America. The fossil species 

 of Megatherium and Megalonyx, however, are found in both 

 Americas. — The order Pachydermata is remarkable for the size of 

 most of its species, and the number of the extinct species is more 

 than double the recent ones in the New World. Only two genera 

 and three or four species belong both to North and South America. 

 Fossil elephants and mastodons occur in the most distant parts of 

 North America. Although the present race of horses is certainly 

 of European origin, yet fossil bones of this quadruped are met with 

 in Kotzebue's Sound. — Thirteen species of Ruminantia were enu- 

 merated, two of which are common to the old and new continents, 

 and have a high northerly range. The North American deer are 

 very imperfectly known. The reindeer reach to Spitzbergen and 

 the most northerly of the American islands, and range southwards 

 as far as Columbia River on the Pacific coast, and to New Bruns- 

 wick on the Atlantic. Although the musk-ox ranges from the 

 barren lands over the ice to Parry's Islands, it is not found either 

 in Asia or Greenland. — There appears to be nine species of Ceta-" 

 cea, known as North American, and those on the east coast are 

 mostly inhabitants of Europe also, under the' same parallels of lati- 

 tude, especially those of the Greenland seas. On the western side 

 the species are common to Asia also. — Tlie report then proceeded 

 with an account of the Ornithology, which Dr Richardson said it 

 would be unnecessary to touch upon at so great length or with so 

 much detail as the Mammalia, since the species were so much better 

 known, a great majority of them being migratory, and therefore 

 those which lived in the less frequented regions were, at stated 

 seasons, visitants of the more civilized districts. Local lists, how-
