PJIcher-plant Mosqiiilo. — Mr. J. Turner Brakeley, of 

 Horncrstown, N. J., has very kindly supplied the Aqua- 

 rium laboratory with numerous larva? of mosquitoes. One 

 species, Wyeomya sinithii, the pitcher-plant 

 mosquito, winters in the larval stage, frozen 

 solid in the small ice masses filling the pitcher- 

 plants (Sarracenia). The eggs are hatched 

 out in the autumn-. The other species, Ciiltx 

 canadensis, the' woodland pool mosquitn. 

 hatches from the egg at favorable times dur- 

 ing the winter; the egg wintering in the mini 

 at the bottom of the pool. The accom- 

 panying photograph shows the actual size of 

 some of the pitcher-plants received from Mr. 

 Brakeley. That portion of the leaf forming 

 the pitcher is four inches long and one and a 

 half inches diameter at the widest part, and 

 may contain 75 to 100 larva:. It is a satis- 

 faction to be able to state that the pitcher 

 plant mosquito is not a biting species. 



Fish Hatchery. — During the second and 

 third weeks of January the Aquarium fish 

 hatchery was supplied by the United States 

 Fisheries Bureau with many thousands of 

 eggs of brook trout, lake trout, and rainbow 

 trout, all of which hatched out before the 

 end of Fcb]'uary. White-fish eggs were also 

 received in January, hatching out by March 

 16th. Eggs of the land-locked salmon ar- 

 rived on March 24th. 



A lot of sculpin eggs from Gravesend Ba}-, 

 collected on January ist, hatched in salt- 

 water before the end of the month, but the 

 young were lost, as no method could be found 

 for feeding them. They were hatched in McDonald jars, 

 like the whitefish. 



The brook trout — passed along into the rearing bo.xes — 

 have already absorbed the yolk sac and are beginning to 

 feed; the other trout are not so far advanced. .All young

fry, when ready for transportation, will be turned over to 

 the New York Fish Commission for planting in State waters. 

 The exhibition tanks now contain yearling and two-year-old 

 brook trout, rainbow trout, brown trout, .At- 

 lantic salmon, and whitefish ; also yearling lake 

 trout and quinnat salmon, all from our own 

 hatchery. These home-raised fishes are better 

 for exhibition purposes than wild specimens.

 Fish Trade oj New York City. — The 



wholesale trade in fishery products in this 

 city constitutes a business of greater pro- 

 portions than the public is generally aware 

 of. Omitting the retail business entirely, 

 the amount of fish, oysters, clams, lobsters, 

 etc., brought to the city from various 

 sources is worth over $13,000,000 a year.

 Noi'a Scotia Trout.— The fine collection 



of sea-run brook trout from Nova Scotia, 

 recently exhibited at the Sportsmen's Show-, 

 is now in the New York Aquarium, having 

 been presented by Mr. D. G. Smith, Fishery 

 Commissioner for New Brunswick. Most of 

 the northern trouts take to salt-water at times, 

 when they are known as "salmon trout."

 The director and staff of the Aquarium dis- 

 claim all responsibility for misleading articles 

 in the daUy press, respecting the Aquarium. 



It should be stated that the fishes in the 

 building are not going blind, as recently re- 

 ported, and that there are only five cases of 

 blindness in the entire collection of over 2,000 

 fishes. Four of these are due to injuries received during 

 shipment, and the specimens are only temporarily blind. 

 When merely the surface of the eye is injured, fishes re- 

 cover their eyesight. This trouble is well understood at the 

 .\quarium.
