cii GENERAL SUMMARY OF SCIENTIFIC AND 



on the nose. Still another was about as large as the elephant. 

 Its cheek-bones were enormously expanded, and its horns 

 were flat. A fifth had triangular horns, turned outward. The 

 four last species have been placed in the new genus Syinho- 

 rodon. Among a number of remains of fossil vertebrates 

 from the phosphate beds of the French eocene formation are 

 those of a Lemurian monkey, called by the discoverer, M. 

 Delfortrie, Palmolemur. He also thinks that these low mon- 

 keys were characteristic animals of the Paris basin. M./Ger- 

 vais thinks that this French Lemur is allied rather to the 

 living forms of Indo- Africa, or Galago^ than the forms found 

 in Madag^ascar. 



The Fishes have engaged the attention of Dr. Gtinther, Mr. 

 Putnam, and others. A new ganoid has been discovered in 

 Russia, allied to an American form. Mr. Putnam has pub- 

 lished a paper on the species of Liparis^ and of 3Iyxine and 

 JBclellostoma^ and found that the species of Myxine have a 

 great geographical range. The Amphioxus has been studied 

 afresh by Dr. Stieda, of Dorpat. This animal, the lowest ver- 

 tebrate, is cosmopolitan in its distribution. He finds that 

 the male and female Lancelet can not be externally distin- 

 guished from each other, but a microscopical examination set- 

 tles the question at once, and Owen's suggestion that this 

 animal may prove to be the larva of some larger unknown 

 fish is rendered impossible. That, however, a fish called Lep- 

 tocephalus, which presents many signs of immaturity, such as 

 a very imperfect skeleton, the vertebral column being repre- 

 sented only by a dorsal cord and some membranous parts, 

 and other characters of such a nature as to lead Kolliker to 

 regard it as the type of a separate order that this is the 

 young of some well-known higher fishes has for some time 

 been supposed by ichthyologists. Indeed, Professor Gill 

 has for a long time seen in it a very young Congei\ M. Da- 

 reste following him in this view. Both this and the Le23to- 

 cephalus have a swimming-bladder, in relation with some 

 red bodies, and in other respects the Leptocephalus seems 

 the young of the Conger-eel. They also think that the other 

 so-called species of Leptocephalus are immature forms. An 

 important illustrated memoir on the scales, and a short pa- 

 per on the structure and development of the fins of the 

 bony fishes, have been published by M. Baudelot, in Lacaze-
