56 ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 



the soft rays of the anal. In the figure of H. insolatus in the " Histoire des 

 Poissons," these rays are represented of the same length as the second spine, 

 whereas in the present species they rather exceed it, giving a greater depth to the 

 entire fin. The teeth also would seem to be more developed in the H. Crusma, 

 especially those in front, which are longer than the others. According to Valen- 

 ciennes, the outer row hardly exceeds the inner ones in the H. insolatus. The 

 geographical position of the two species is however widely different. The 

 H. insolatus is a native of the Caribbean Seas ; whereas the H. Crusma has only 

 been obtained on the coast of Chile and off the island of Juan Fernandez. M. Gay 

 first obtained it at Valparaiso, where also Mr. Darwin's specimen was procured ; 

 in whose notes it is stated, that it gets to a much larger size than the one here 

 described.

Form. — General form not very dissimilar to that of the C. Aurata. Greatest depth contained 

 about three times and a half in the entire length. Depth and length of the head equal, each 

 about one-fourth of the entire length. Profile very oblique. Eyes high, and moderately large, 

 distant two diameters from the end of the snout. Preopercle with the angle at bottom very 

 much in advance, giving an obliquity to the ascending margin ; the limb not very broad, and 

 naked ; in front of the limb are about four rows of scales smaller than those on the body : the 

 same number of rows of scales on the opercle. Jaws equal, with eight conical incisors in front 

 of the upper one, and ten in front of the lower;* those above longer than those below, and more 



* There are actually nine, but one appears to have been lost.
