212 OBSERVATIONS ON FISHES.

 cepting the eyes, which are enormously large and 

 protuberant. The length of the head and body, 

 measured from the end of the snout to the setting 

 on of the caudal, is three inches and a half. The 

 greatest depth is two inches and a half ; being five- 

 sevenths of the length instead of about one-third, as 

 in a fish of this species of ordinary proportions.

THE occasional occurrence of single individuals 

 of species in situations where they are not known 

 generally to inhabit, especially species that are rare, 

 and hardly considered as abundant anywhere in the 

 country, is sometimes a very puzzling circumstance. 

 Birds, which have the power of transporting them- 

 selves by wing to great distances, may accidentally 

 wander to many localities in which they would be 

 accounted strangers. Quadrupeds, and a few other 

 land animals, though more limited in the possible 

 extent of their range, may still, from some casualty 

 or other, be carried far beyond their usual beat : the 

 smaller ones, like insects, may escape observation for 

 some time where they are really plentiful. But the 

 difficulty is much increased in the case of the larger 

 aquatic animals residing in waters which have no 

 communication with the sea, or rivers. And such is 

 the case in the instance to which these remarks al-
