Call in his ' Life and Writings of Rafines- 

 que ' these must have been written but five 

 months before his decease and his quarrel 

 with Professor Wagner probably ended his 

 scientific associations in this City. 



In looking up the date of his death I have 

 been struck with the fact that Lippincott's 

 Biographical Dictionary, Simpson's 'Lives 

 of Eminent Philadelphians' and Appleton's 

 Cyclopedia of American Biography quote 

 the date of his death as Sexitember 18, 1842 

 and the National Cyclopedia of American 

 Biography is the only authority that I can 

 find for the year 1840, which is used by 

 Call.

SOME OBSERVATIONS CONCEBNINO SPECIES 

 AND SUBSPECIES* 



Some few weeks ago I gave to this Society 

 a brief general account of the investigations 

 which the Fish Commission carried on at 

 Lake Maxinkuckee during the past summer 

 and fall. 



At this time, I desire to speak briefly 

 concerning two new fishes obtained in these 

 investigations, and certain questions con- 

 cerning species and subspecies which their 

 study has suggested. 



In the first place, permit me to repeat 

 some of the statements regarding the lake 

 and its small tributary streams. 



LakeMaxinkuckee is located in the south- 

 west corner of Marshall County, Indiana, 

 on the Logansport and Terre Haute railroad, 

 32 miles north of Logansport, or 34 miles 

 south of South Bend,. Indiana. It is about 

 2.75 miles long, from north to south, 1.75 

 miles wide, and is quite regular in outline. 

 This, like all the lakes of northern Indiana, 

 is of glacial origin. Its greatest depth, so 

 far as known, is 86 feet. The bottom is of

compact sand and gravel near the shore, 

 then a wide bed of marl, and soft mud in 

 the deeper parts. There are only 1 or 2 

 short i-eaches near the shore where the 

 bottom is soft. The water is relatively 

 pure and clear. The bottom temperature 

 in summer is 47° to 50° Fahr., while the 

 surface gets as warm as 77° to 80°. 



The lake is well supplied with aquatic 

 vegetation ; Chara, Potamogeton, Myriopliyl- 

 lum, Ceratophyllum, Nitella, Vallisne7-ia and 

 Scirpus being abundant. At least ten species 

 of Potamogeton occur and two species of 

 Scirpus are found. Chara is very abundant, 

 great beds of it covering the bottom in 

 many places from near shore out to a depth 

 of 12 or 15 feet. 



The catchment basin of the lake is small. 

 There are no tributary streams except one 

 very small brook at the south end, a some- 

 what larger one at the southeast corner, 

 and three small ones upon the east and 

 northeast sides. The total amount of in- 

 flow from these little creeks is but a few 

 gallons per minute. They are all short, 

 sluggish streams and do not vary greatly in 

 size at any time. Perhaps the only ones 

 deserving mention are (1) the one at the 

 southeast corner which is popularly known 

 as 'the inlet,' (2) one near the middle of 

 the east side, and (3) one at the northeast 

 corner flowing into Culver Bay, and which 

 has come to be known as Culver Inlet. 

 The stream on the east side has been called 

 Aubeenaubee Creek, from the Pottowat- 

 tomie chief of that name who at one time i 

 owned the land on the east of the lake. 

 It was from this small creek that the speci- 

 mens of the new species were obtained. 

 Aubeenaubee Creek does not exceed 1.5 

 miles in length. It has its source in a 

 small marsh, and is a sluggish stream flow- 

 ing through a low, level meadow or prairie 

 region. It is about 4 feet wide and aver- 

 ages only 3 to 6 inches deep, with deeper 

 holes at intervals. Through most of its
