precisely similar to my own, which allowed its pearl-like drops to 

 escape from the extremities of its leaves. 



Is the remarkable and sometimes violent movement of my Colo- 

 casia due to an exception — namely, the accidentally imperforate con- 

 dition of the stomata, and the incessant shocks of an imprisoned 

 sap? 



On the other hand, M. Musset says that the leaves of his Colocasia 

 present violet reflections on their upper surface ; mine is throughout 

 of a pale green. Can we have studied different varieties ? 



M. Musset carried on his cultivation in the open ground ; I mine 

 in a hot stove : the difference of the stations may have had some 

 influence upon the results. Might there not be, also, in these ener- 

 getic spontaneous movements some transformation of heat into mo- 

 tion, just as in the Arums there is a development of heat at the mo- 

 ment when fecundation is about to take place. — Comptes Rendus,

Characters of new Fishes. By Dr. F. Steindachner. 



Ctenotrypaucheny g. n. — Distinguished from Trypauchen by its 

 large cycloid scales, an elevated dentated ridge on the occiput, and 

 only three branchiostegal rays. 



C. chinensis. — Length of head contained about 5f times, depth of 

 head about 6^ times in the total length. Eyes extremely small, 

 scarcely visible externally ; body elongated, ribbon-like. Dorsal, 

 anal, and caudal fins united into a single fin. The dorsal contains 

 6 spines and 46 jointed rays, the anal 1 spine and 42 jointed rays. 

 Along the lateral hne 46 scales. Colour light yellowish brown, with 

 a narrow reddish-violet band along the lateral line. China. 



Heros Troschelii. — Distinguished from H. urophthabnus by the 

 greater number of dorsal spines (16), and by the lower jaw over- 

 hanging the upper only on the sides. Mexico. 



Ctenolabrus Brandaonis. — Dorsal spines 1 9 ; b-Q rows of scales 

 above the lateral line ; depth of body contained 3f times, and length 

 of head 4 5 times in the total length ; 5 rows of scales beneath the 

 cheeks ; 37-38 scales along the lateral line. Brazil. 



Batrachus liberiensis. — Body completely and distinctly scaled ; 

 second dorsal with 25, anal with 22 jointed rays; head one-third the 

 length of the body (without the caudal) ; breadth of the head six- 

 sevenths of its length. No tentacle over the eye. Liberia. 



Caranx macrops. — Forms a transition towards Vomer by the 

 small elevation of the first dorsal ; the maxillary teeth lie in several 

 rows one behind the other, and are exceedingly delicate and line, 

 with the exception of the larger cutting-teeth in the outer row. 

 Depth of body contained 33 times, and length of head 4| times in 

 the total length. Body finely scaled ; 40 scutes along the lateral 

 line ; 8 transverse bands on the sides of the body. Liberia. 



Arius Capellonis. — Nearly allied to A. Jleudelotii, Val. ; but the 

 occipital region is much more strongly arched, the dorsal and anal 

 fins are considerably higher, and the adipose fin much longer than
