BULLETIN OF THE UNITED STATES FISH COMMISSION. 
This spawning-bed was tine gravel covered with 1 to 2 feet of moderately flow- 
ing water. Before the haul was made the abundance of fish there was evinced by the 
constant “dipping” of their tails on the water surface, where it is said the spawning- 
takes place with this as well as other species of white-fish, though the eggs sink. 
There are but two instances of the introduction of non-indigenous white-fishes 
into Maine waters. One was Cor eg onus clupeiforrnis the other Coregonus albulo , 
with either of which Coregonus Stanley i is unidentifiable. Regarding the former, in 
a letter dated April 1, 1901, Commissioner H. O. Stanley says: 
Some twenty years ago the United States Commission sent me some white-fish eggs, I think from 
one of the lakes in Michigan. I hatched them at Rangeley and planted them in the upper lake — 
Rangeley. This winter they have been caught with hook and line in considerable numbers in 
Umbagog Lake, which is the fourth lake below. This is the only lake in which fishing through the 
ice is allowed. It is a pickerel lake. These white-fish were caught with a small live minnow. I have 
had some sent me twice this winter; they run in size from 11- to 2 pounds. I presume they are in the 
lakes just the same and could be caught if fished for in the same w'ay. It seems queer that they 
should turn up in the lower lake first, some 40 miles or more away. They are surely white-fish and 
none has ever been seen in Rangeley waters, to my knowledge, till this year, and I have been familiar 
with them all my life. 
The other case was a single plant, concerning which Superintendent Charles (f . 
Atkins, of Craig Brook Station, writes that having searched the records, as well as 
his own memory, he finds that he has knowledge of only one introduction of such 
species- -namely, that of Coregonus albula, of which an importation of eggs was 
hatched at Craig Brook in the spring of 1886, and all the resulting fry, estimated at 
51,000, were planted in Heart Pond at East Orland April 21 of that year. 
Coregonus stanleyi Kendall, new species. 
Description: Head 4.52 in length; depth 4.33; eye 4.66 in head; snout 3.81; D. 10; A.ii, 14; scales 
10-82-7; gillrakers 10+17 and 11+17, the longest 1.6 in eye. Body fusiform, not very deep, some- 
what compressed, back gradually curving from the tip of snout to front of dorsal; head rather sharply 
rounded, not truncate as in C. labradoricus; vertical height of head from edge of branchiostegal mem- 
branes to occiput about 1.6 in length of head; maxillary reaching front of eye, 3 in head (maxillary 
measured from tip of snout); mandible nearly 3.5 in head; dorsal inserted in front of ventral nearer 
snout than base of caudal, its anterior rays extending considerably beyond tips of posterior rays when 
depressed, the longest 1.23 in head; pectoral 1.27; ventral 1.4, and anal 1.82 in head; anterior rays of 
anal not nearly reaching tip of posterior rays when depressed; caudal deeply forked, the peduncle 
slender, compressed, the distance from anal to first lower rudimentary rays of caudal equal to distance 
from adipose to upper rudimentary rays of caudal and equal to length of base of anal. 
Body and head covered with white tubercles, small and dot-like on the back and belly, 1 and 2 
on each scale, large and more prominent on the head and sides of body, those of the sides raised and 
elongate, arranged in linear series, one on each scale. 
Color after preservation in formalin and subsequently in alcohol: Back, top) of head, tip) of snout, 
and around eyes, blue-black; sides and under parts yellowish, the scales margined with dusky dots. 
The white tubercles give the body the appearance of being striped with narrow white lines. Dorsal 
and caudal with blue-black rays and p»ale membranes; pectorals, ventrals, and anal with pale rays and 
slightly dusky membranes. The color when fresh was somewhat lighter, the belly and sides being 
more nearly white. The present color is intensification of the original shades. 
a We were presented by Professor Baird, from the establishment of FrankN. Clark, Northvilie, Mich., 1,000,000 white- 
fish eggs. Owing to the extreme cold weather, long distance of transportation, and tenderness of the eggs, the percentage 
of loss was large; should judge about 25 per cent of the eggs hatched. They were received in February: were hatched 
and turned loose March 20. About 15,000 of these were put in Rangeley, the balance were turned loose in Mooselucme- 
guntic Lake. (Report, of the Commissioner of Fisheries and Game of the State of Maine, 1581 (1882), 10.)
