118 FISH FOR THE MARINE AQUARIUM. 



mon sucker (Catostomus communis); but it is comparatively a 

 large fish, measuring fourteen inches in length when full 

 grown, and, therefore, too big for a parlor Aquarium. 



Mr. Hibberd recommends the Bknnius pholis or common 

 Tansy of the English, which answers to our six-banded 

 Chasmodcs (Chasmodes bosquinanus) . It is, however, a rare 

 fish in America. lie likewise recommends the sand-launce, 

 a local species of which (Ammodytcs Amcricanus) is not 

 rare. It is a small fish about four inches in length, and, 

 consequently, a good one for the Aquarium. They bury 

 themselves in the sand when the tide recedes, and may 

 be procured by being dug out. 



There is one funny little creaturo that stands alone 

 among fishes, in having a prchensible tail, by means of 

 which he holds on to sea-weeds or floating objects. This 

 is the Hudson river sea-horse (Hippocampus Hudsonhus) 

 a figure of which I have given (PI. I., Fig. 1), and being 

 only six inches in length when full grown, and found so 

 near to us might, if it would live, be an acquisition to a 

 marine Aquarium. I have not, as yet, been able to try it, 

 but think that, from its resemblance to the pipefishes and 

 sticklebacks, and also from the seeming toughness, not only 

 of its shell, but of its constitution, that it might bo intro- 

 duced with advantage.
