recherches de M. Feytaud, complètement élucidée. Bien des 

 questions restent encore en suspens. Maeterlinck invoquait 

 pour les abeilles 1' " esprit de la ruche. " Existe-t-il ? Et, 

 en ce cas, y aurait-il un " esprit de la termitière ?" Ce sont 

 là hypothèses fragiles, solutions incertaines qui ne font que 

 reculer le problème sans le résoudre.

A CYPRINID NEW TO SCIENCE. 

 By Philip Cox, Ph. D., University of New Brunswick. 



This minnow (Leuciscus rubrilateralis Cox) was discovered 

 by the writer in the summer of 1897 while he was investigating 

 the fresh-water fishes of the peninsula of Gaspé, P. Q. It was 

 generally associated with Couesius plumbeus Agassiz, but in 

 some of the rivers, i. e. Nouvelle and Grand Pabos, it was the 

 dominant form. At that time the fish was diagnosed as the 

 eastern représentative of C. dissirnilis Girard, or a variety of 

 C. plumbeus ; and, as the latter, was reported to the Royal 

 Society of Canada (Fresh Water Fishes and Batrachia of the 

 Peninsula of Gaspé and their Distribution in the Maritime Pro- 

 vinces of Canada, by Philip Cox. Ph. D., Trans. Royal Soc. Can., 

 Vol. V, Sect. IV, p. 148, 1899). 



A subséquent and more critical study of the few spécimens 

 preserved seemed to confirm that view, and it was published as 

 C. p. rubrilateralis Cox (Cyprinida; of Eastern Canada, Bull. 

 No II., Proc. Nat. Hist. Ass., Miramichi, 1901, p. 42). 



In August, 1918, numerous spécimens of this minnow were 

 taken by the writer in Black Brook, Loggicville, Miramichi, 

 N. B., and carefully diagnosed, when the two most important 

 characters, namely, the dental formula and the présence or 

 absence of the barbel were more satisfactorily determined from 

 the examination of a large quantity of fresh material. It was
