CARP, DACE AND MINNOW. 417 
and numerous curious and perplexing forms have resulted from such 
intermixturing. 
The so-called Carp of the Hudson appears to be either escaped Gold- 
fish or some inferior hybrid form of the ‘‘Karausche’’ type. Those 
introduced into California a few years ago by Mr. Poppe were an inferior 
strain of Scale Carp. The ‘‘Carp’’ of Virginia is a sucker, Carpiodes 
cyprinus. 
THE GOLD CARP. 
The Gold-Carp, the favorite of aquarium-keepers, is constantly becoming 
more popular, and many thousands have been distributed by the United 
States Fish Commission within the past few years, incidentaily, in con- 
nection with the work on food-fishes. It frequently escapes from domes- 
tication, reverts to the natural hue of olive-bronze, and is taken in nets 
and brought to market. The graceful long-tailed and triple-tailed vari- 
eties from Japan are reared by the Fish Commission as well as the silvery 
and the parti-colored forms, silver and gold. Mr. Seal has by artificial 
selection produced some grotesque forms, surpassing even them of Japan. 
“The Gold-fish and its Culture,’? by Hugo Mulertt, of Cincinnati, is 
a book worthy of a place by the side of every aquarium. Henry W. Elliott, 
of Cleveland, has had fine success in hatching then in open, ornamental 
ponds, and has described his experience in the Bulletin of the United 
States Fish Commission.
