In a state the size of Illinois, with its peculiar environments, the enforcement of the law on an equitable basis is a rather difficult prob- lem for the commissioners to handle. Peculiar conditions exist in the northern tier of counties, in that the water is principally cold spring lakes, particularly adapted to the gamier varieties of fish, while in the middle and southern portion, water more sluggish, easier affected by rains and overflows, while replete with game fish, yet is distinctively a proper habitation for the coarser fishes. It is desirable to utilize the coarse fish at all seasons of the year except during the spawning season, and in order that they may be taken, particularly while the lakes and rivers are covered with ice, it becomes necessary for the commissioners to issue permits governing seining during that time. In the northern part of the State, the deep lakes, such as Fox lake and the beautiful lakes in Lake county, the fishing there means the taking of large quantities of the gamier varieties, such as the pike and pickerel at a time when they are practically nearing their spawn- ing period, and the law relative to fishing under the ice has to be rigidly enforced. Illinois, on account of its great length, has an immense river front- age, and throughout the State a perfect network of rivers and lakes exist, and while the interest in the protection of fish has increased greatly and very many fishermen are aiding in the enforcement of the law for their protection, yet there is a large number of irresponsi- ble parties who are constantly taking advantage of every opportunity, whether lawful or not. We have for the service of the enforcement of the law, five paid wardens, and it is impossible for them to cover the territory and do it full justice. Chicago demands the presence of one all the time, and in order that the service there might be prop- erly performed, it should have two. A glance at the reports of the warden in Cook county will show the extent of the work expected of him there and in that vicinity. The tendency to sell small and illegal sized fish is, or seems to be, inherent to every small dealer in the city, and as a consequence very many of them take the chance of working off small and inferior fishes because they can be obtained at a very low figure, the wholesale houses hardly daring to offer them for fear of prosecution or confiscation. Some idea may be had of the difficulty of enforcing’ the law when it is understood that the lakes adjacent to the rivers are as a rule far 8 enough inland to give practical protection to a gang of fishermen who wish to work them at night with small meshed seines and the difficulty for those enforcing the law to get any evidence of such violation. What we need is force enough to properly police the whole State. The commissioners are very severely criticised for not obtaining bet- ter service, and one would alinost be led to believe that the public opinion of the duties of the commissioners are to lie out in the woods at night and undertake to apprehend violators of the law. The commissioners, serving without salary, have at best a large contract on their hands to take care of the ordinary routine of work which falls to their lot, and should be given assistance enough to properly police the waters. We have suggested that the warden force be at least doubled, and that a proper man be placed at their head under salary, subject to the control of the Board of Fish Commis- sioners. For local reasons it is very difficult to obtain conviction at various points along the rivers, there being a marked prejudice against the enforcement of the law which would tend to curtail the business of the fishermen, whether lawful or not, and the greatest difficulty has been encountered in successfully prosecuting offenders. Mr. Cohen, who has charge of the enforcement of the law, has given his time to the work at a great detriment to his business and feels as if now that the work has been practically organized, that he should have help enough to successfully carry it on without claiming so much of his time and personal attention. f The use of the steamer Illinois in patroling the Lllinois river has been of material assistance during the close season. Excepting in the season of 1894, constant supervision of the Illinois river has been exercised. The seines used in the river are of such length and size that it is dangerous to use them with the boat in the river. The use of the seines, however, has not been frequent, and the law has been better observed than in former seasons. This, howeyer, is not true of inland lakes and streams where the small seines and trammel nets are used principally at night, and while not nearly all such violations have been detected, yet a large number have been. Warden Sites, of Homer, Ill., has made an enviable record in his work, having obtained more convictions than any other one man, and has done more to enforce the provisions of the fish law than any other warden in the State, outside of Cook county. He is a fearless officer, perfectly honest and loyal to his superiors and the interests of the State. His report, which will be found under the proper head- ing, will show the results obtained. The other wardens have done good service, and although handicapped by local conditions, have, as a rule, used good judgment and discriminated fairly between pro- secution and persecution. While all have done their’ duty, yet the number is inadequate to anything like a perfect enforcement of the law. In many places we have had to rely on local deputies, who, serving without fixed pay, and depending on fines alone for compen- sation, frequently find that their time and work have been given for nothing, owing to the difficulty in recovering the fines, which have been assessed and collected, from the State’s attorneys, who seem to 9 have a lien on all fines collected up to a certain limit, although our statute covering such collections makes it obligatory on all justices of the peace to turn over the fines to the State Treasurer. The fines collected from all sources and now in the hands of the State Treas- urer fall short of $500.00. If these fines could be utilized as intended by the law, as we understand it at least, as was the intent when it was enacted, we think we should have money enough to employ several additional wardens. So far we have found no means of com- pelling the remittance of fines to the State Treasurer in accordance with the law, except in a few instances, as stated. We do not wish to be understood as finding too much fault, as results show improvement in conditions in many respects. A com- parison of the extent of the violations of law for the past two seasons shows a very marked decrease over the record of former seasons, and a corresponding increase in the enforcement of the law, but even with noted improvement, there is still room for more. We have had considerable trouble with express companies and common carriers, as they will accept packages of fish that are not properly labeled. The effect has been to allow dealers to ship game fish, illegal to catch, in unlabeled packages, and such violations are only provable when such fish are found in the hands of a dealer, and the shippers are comparatively secure, because evidence against them sufficient to convict them can not be obtained. All manner of schemes are used, of course, to evade the provisions of the law, and with our limited force, many of them are successful, but we are glad to note that we are gradually obtaining the assistance of the transportation companies in the matter. The express com- panies have nearly all issued such notices to their agents as will insure a better compliance with the provisions of law in regard to the shipment of unlabeled fish. REPORT OF PRESIDENT COHEN, IN CHARGE OF ENFORCEMENT OF Law. Fish food being as essential to mankind as any other animal food, a strict enforcement of the law for the protection and perpetuation of fish is of vital importance both to present and future generations. As population increases, the demand becomes greater. The constant drain on the waters increases year by year. Commercial fishermen and sportsmen have made sad havoe in this State in some of the beautiful lakes and streams which nature has provided so bountifully with game fishes and the coarse varieties of food fishes. To secure a complete restoration of the former conditions in our lakes and rivers, a rigid enforcement of the law is absolutely esséntial. Considering a river frontage of 1500 miles, together with the numerous lakes and ponds that require protection, our warden service is inadequate. The statutes provide for only five wardens. Because of the great area of water requiring constant attention, we are unable to cope with the situation, with the limited means provided by law, and would recom- mend that the General Assembly amend the law by appropriating a sufficient sum to increase the number of wardens, so as to give the entire State ample protection. 10 We regret to say that in some localities, it is impossible to secure a conviction, no matter how flagrant the violation may be. In one instance we found the justice in sympathy with the defendant, and openly asserting that protection is a farce, and that people should be allowed to take fish as they choose. We frequently have difficulty to get the State’s attorney to prosecute; apparently he fears he may offend some of his constituents by enforcing the law. The Attorney General has ruled that all violations must be prosecuted by the State. We are sometimes at the mercy of officers who are not in sympathy with our work, and in such cases we-are almost certain to fail to bring the guilty to justice. We would suggest that the law be amended so as to give every constable and deputy sheriff authority to make arrests for violations and to receive the entire fine after case has gone through the proper channel. This provision will stimulate all officers in authority to interest themselves in the protection of fish, and ob- viate the necessity of sending regular wardens in localities where prejudice against outside interference exists. With an amendment covering the suggestion made herein, and with sincere coéperation of the sportsmen of the State, there will be no difficulty in reducing the violators to the minimum, and restoring the depleted lakes and rivers to their primitive condition. In 1899 the Legislature wisely enacted a law regulating the catch- ing and shipping of fish, making it a misdemeanor to ship them un- less they were marked as specified by law. All packages containing fish shall be labeled in plain letters on the addressed side of the_ package, so as to disclose the fact that the package contains fish, and stating kind of tish contained therein. The object of this amendment was to prevent dealers from shipping the different species that were prohibited by law. Bass for instance is a prohibited fish, and can only be taken in the waters of Illinois by hook and line. The reason for this is that 85 per cent of the fish taken in our waters are of the coarse varieties, such as carp, buffalo, dog-fish and gar. The remain- ing 15 per cent are classed as fine fish. The coarser varieties are taken exclusively for commercial purposes, and are the means of sup- porting thousands of people living along the Illinois and Mississippi rivers. These fish are shipped to New York in 150 pound boxes, marked, for example, “Illinois River Carp,” and are esteemed very highly. A more detailed account of this industry is described under another head in this report. The 15 per cent referred to consists of bass, croppies and sun-fish. While there is no law protecting any of these species, except the bass and pike, the sizes of other species named are regulated so that no immature fish of any other varieties are allowed to be shipped. The express companies and other com- mon carriers have manifested a disposition all along to codperate with us in the enforcement of this measure, and have notified their- agents throughout the State to refuse all packages not properly marked. It is rare to find a package in transit now that is not labeled according to law. The amendment passed and approved in 1899, which reads as fol- lows: “That it shall be unlawful for any person to set or cause to be set or used in the waters of Lake Michigan within a quarter of a mile IE of the main shore thereof any gill, pond or fike nets; no dip nets shall be used except for catching minnows for bait, said dip nets not to exceed twenty inches in diameter.” Prior to the passage of this law, there were no less than 2,800 of these dip nets in close proximity from Hyde Park to Twelfth street, on the Chicago lake front, operated, as a general thing, by classes who had no respect for the law, catching and disposing “of immature fish, depriving people who were disposed to fish with hook and line according to law. We are indebted to Chief O’Neil of Chicago for giving us willing assistance to abate this nuis- ance that has been a menace to that locality for so many years. Our wardens did their utmost, but were unable to overcome the constant resistance of overwhelming numbers of these law-breakers. Orders were given by Chief O’Neil to the different superintendents to give whatever assistance our wardens required, and in a short time the en- tire lake front was freed from these unlawful devices, and has so con- tinued, through the untiring efforts of our wardens, who patrol that portion of the lake front daily. People have an opportunity now to get a few hours of excellent fishing certain seasons of the year, afford- ing them good sport and excellent food supply without leaving the city. Uniform laws governing states bordering the great lakes are very essential. and if properly enforced, would be the means of protecting and perpetuating the valuable species indigenous to these magnifi- cent inland seas. Michigan, Wisconsin and Indiana should unite with us in framing laws to arrest the indiscriminate destruction of this indispensable food supply. We are in communication with the commissioners of each of these states, urging them to use their efforts to secure legislation that will prevent fishermen from any of these states operating in one of the others during the closed or prohibitory season. A rigid enforcement of a law of this kind would be the means of the restoration of the larger species of white tish and trout that were so abundant in former years and are scarcely seen in our markets now, except a limited supply from Lake Superior, that body of water being inaccessible to commercial fishermen the greater por- tion of the year. The time has arrived when the lawmakers of states bordering the great lakes should agree and adopt uniform laws, giving . their commissioners power to act jointly to prevent the total annihil- ation of a great industry and great food supply of generations to follow. A noticeable change in the condition of lower Lake Michigan has taken place since the drainage commissioners have reversed the course of the Chicago river. For several years white fish and trout were conspicuous by their absence from this portion of the lake. The paramount cause may be attributed to the constant flow of sewage emitted through the Chicago river into the lake, precipitating poisonous refuse upon the spawning beds that were occupied in former years by these valuable species. We are reliably informed that since the course of the river has changed, these species are re- inhabiting their old haunts, and are becoming quite abundant in that locality. This demonstrates that pollution is a prime factor in the 12 destruction of our game fishes. We recommend such legislation as will prevent rendering establishments and like institutions from dis- charging their refuse into the streams and lakes of the states. There has been considerable controversy and much correspondence with the commission relative to the inch and a half mesh for seines and nets now operated by market fishermen in rivers used for com- mercial navigation. This reduction in the size of mesh was advo- cated by the commissioners for various reasons. First, the law regulates the size of fish that shall be taken and offered for sale. Fishermen are required to return to the water all immature fish. If they comply with this law, the size of the mesh is immaterial. Sec- ond, nothing larger than an inch and a half mesh will take the gar, the most destructive of all fishes. These predatory ganoids gather as sentinels by the thousands at the mouth of every slough and outlet, lying in wait for the bass fry, after the parent fish leaves them to care for themselves. Few escape the onslaught of this army of water pirates. More game fish is annihilated by the gar in one year than violations of every character would annihilate in ten. In December last, John Schulte, of Havana, took, with an inch and a half mesh seine, 35,000 pounds of gar in one haul. It took almost six weeks to destroy them. Mr. Triggs, of Chicago, to whom the commissioners gave permission to take the objectionable fish from the Fox lake region, took 10,000 pounds of these pests in one haul with the inch and a half mesh seine. Considering the utter worthlessness and destructive habits of this fish, is it not wiser to use tackle that will rid the waters of this enemy that is rapidly depleting’ our rivers and lakes of the gamey varieties? We are frequently petitioned by hunting and fishing clubs to issue them permits to remove the objectionable fish from the lakes and streams controlled by them for preserves. When we are assured that these permits are requested for the sole purpose of eliminating the undesirable fish, and not from mercenary motives, the request is granted. The conditions stipulated by the commission are that all fishing must be done under the supervision of a warden appointed by the board, to see that nothing but objectionable fish are taken, and the gamey species returned to the water. Not less than fifty permits have been issued to clubs for this purpose in the last two years. We are anxious to cdoperate with the sportsmen, granting them all the privileges that the law places in our power, so that they may be able to remove the undesirable fish that have almost depleted the lakes and ponds of aquatic life so essential to the migratory water fowl. Reports from various clubs are very encouraging. Tons of carp have been taken this season from the Fox Lake region. Similar reports are coming in from other localities. We are in hopes that a few years of strenuous labor in this cause will reduce to the minimum this species in lakes and ponds that are used for preserves. In con- clusion it must be apparent to every thoughtful person that the work assigned to this commission is largely educational. The people have to learn the vast pecuniary values embodied in our fish supplies and the important part these supplies perform in feeding the people. 13 They have to learn that unnecessary destruction of the fishes is tres- pass upon the rights of others, for fish in the public waters are the property of all the people. Punishment for illegal fishing therefore is not only protection, but education. True sportsmen are humane and respectful of human rights. If this sentiment were universal, the enforcement would be easy, the inhabitants of the waters of the State would soon be multiplied more than ten-fold, and the interest of both the sportsmen and the commercial fishermen would correspondingly be enhanced. WARDEN SYSTEM. The Forty-third General Assembly gave as an amendment to our warden service and instead of an unlimited number of wardens who were dependent on convictions and fines for their compensation, five paid wardens. This has proved to be a practical change. Under the old system the enforcement of the law was at least a temptation to persecute and to use the provisions of the law to obtain their fees rather than pun- ish the offender and the personal interference of the commissioners was asked for so often, that it took more of our time to prevent prosecu- tions than to prosecute—in other words the old rule of ‘something for nothing” did not work. Men who spent their time and money to enforce law and found fines not to be collected, pursued other meth- ods to make themselves whole. Under the present paid system, wardens depend on their salary, expenses paid by commission, do not handle any fines, and are not permitted to take money in any way for services. The report of wardens made elsewhere will show extent of work and its value. What we need is an increase in the number of wardens to properly handle the requirements of the whole State. REPORT OF WARDENS’ The wardens are required to make monthly reports to the board of commissioners giving the number of arrests made, the number fof nets and seines siezed, and the number of convictions, if any have been secured. The nets that are taken are delivered to the sheriff of the county in which they are found, and his receipt for them is taken as in the following instance: CuicaGo, Inu. Nov. 11, 1904. Received of Geo. W. Glynn, warden, seven nets taken in Calumet river. [Signed. | TnHos BARRETT, Sheriff Cook County. Chicago, to which all roads in the State of Illinois lead, commer- cially, is the center of trade in the fish industry, and not only from different parts of the State, but from almost every other state as well, are fish shipped to its markets, and naturally, very many undersized fish find their way there among the others and the work of the war- dens in enforcing the law relating to the size of marketable fish has been a difficult one. The lake front for miles has been thickly covered with derricks with dip nets attached with which thousands 14 of pounds of very small fish were taken, and these were placed-on the market, but this practice has been broken up and the lake front is practically clear of these devices now. Calumet lake and river have offered great temptation to the fisher- men in the way of illegal fishing, and in consequence, large numbers of seines and nets have been taken from these waters. The under- sized fish that are found in the hands of the dealers are taken and sent to the various charitable institutions of the county in which they are taken, and a receipt is given to the dealer from whom they are taken and a receipt is taken from the institution receiving them, both receipts being filed in our office. It is but just to say that the dealers with but few exceptions, give up such fish willingly. The violations of the law in Lake Michigan have greatly decreased latterly, at least, in that portion under the jurisdiction of the State of Illinois. Our commission has been working jointly with that of Michigan in the enforcement of the laws, and with good results. The decrease in the offerings of small fish has been quite marked. and the result will be perceptible in its effect on the future supply. The South Water street dealers, as a rule, are now in sympathy with our work and have notified all shippers that undersized fish will not be accepted. Taken as a whole, the commissioners have reason to feel that great advancement has been made. LaACOD OPW Peterses aie. Pech Bi.

Again your commissioners would respectfully call attention to the great damage to fish ensuing from pollution of the streams of the State, and urge such legislation as will correct the abuse. We have of course, only to do with the fish, but from every other point of view the matter should have consideration. There can be no doubt that as a means of breeding disease it is one of the most productive of sources. The beautiful cold, clear rivers of the State are fast becom- ing only common sewers, and cannot help being a menace to life and health. If there were no other means than the use of the rivers to care for sewerage and refuse, it would be a different proposition, but with septic devices that will care for it and do it well, there weuld seem to be no reason why proper legislation should not be had Water foul enough to kill fish should be hint enough to localities that serious consequences would follow in other directions. We are ap- pealed to frequently to assist in preventing the use of such streams for the refuse coming from manufactories, etc., along these steams, but we are powerless to officially help them. The only relief seems to be a suit to abate nuisances which we cannot maintain as commis- sioners. It is a serious question and should be considered. REMOVAL OF OBJECTIONABLE FISH, Our methods permitting and of supervision of removal of objection- able fishes is meeting with favor and practical results. From a large number of places requests for such permits come to us, and as the coarse fish so taken are of value sufficient to compensate the warden whom we designate, for his services, no expense to the State is made. In Fox Lake and region, Mr. M. Henry Kleine of Chicago, has had the matter in charge, and as will be indicated by his reports herewith, the work has been done in a thorough and intelligent manner under his supervision. Mr. Kleine, one of the prominent business men of 33 Chicago, who with others like him, have magnificient homes on Fox Lake, has taken a deep interest in fish matters connected with that region and has given valuable time to it. Our commission feels under great obligations to him. LAKE MICHIGAN. Efforts to enforce the law relating to Lake Michigan have heen kept up and the very best results have followed our efforts. We are assured that conditions are better than for years and with anything like uniform laws, in a few years white fish and lake trout will again be taken in territory covered by the State, for the past twenty years almost extinct. Mr. A. Booth, one of the pioneer fish dealers of Chicago, has re- peatedly stated that the first few years of his business in Chicago it was not unusual for boats to go out in vicinity of Chicago and take full loads of these fishes. The various means to take at all times of seasons causing an immense drain on resources, the pollution of the water and other causes having as stated nearly depleted the waters. THE FISH MARKET OF CHICAGO. The city of Chicago is unique in many ways, but it stands alone in one thing, viz., the Jewish fish market, where the Bohemians, Poles and Hebrews go to buy their fish. There is nothing like it in the United States. South Jefferson street, from Twelfth to Maxwell street, on one side of the street is lined with small, dingy buildings one story high, in which the retail fish merchant displays his stock of fresh water fish. On the outside is a stand on which the fish of all kinds are piled and mixed indiscriminately—black bass, black fins, bullheads, crappies, herring, mullet, pike, pickerel, perch, rock bass, suckers, sheepsheads, suntish, trout, whitefish, and white bass. On the inside of the store are tanks, where the live buffalo, carp and ~ dogfish are displayed, and the customer selects the fish, it is caught in a net, then wrapped in newpapers (a large pile being always on hand), and given to the customer, who takes the live carp and walks out of the store feeling sure of its being fresh. After the fish is wrapped in the paper it is perfectly quiet, although just previously it may prove highly pugnacious in its efforts to escape from its cap- tor with the net. Possibly its new surroundings may numb its facul- ties or maybe it is smothered in the close wrappings of the paper. This is all the more strange as the carp will live longer out of the water than any other fish. Its tenacity is proverbial. The buyers -are of all kinds, from the poor woman that takes two or three small suckers, to the prosperous merchant’s wife, who brings her basket for a mess of black bass at 14 cents a pound or live carp at from 8 to 10 cents. All go through the same routine of buying, selecting the live fish or taking up the dead fish in their fingers, examining it, smelling it to test its freshness, then handing over to the salesman the quantity —3 FC d4 of fish selected, who wraps it up in old newspapers and hands the fish over to the customer, taking pay for the same invariably in silver. The whole transaction is free from wrangling, for the cus- tomer selects his own fish and is to blame if it is not satisfactory. Many stands arc located on the curb along the street, where only dead fish are sold. The side streets in the neighborhood have also their stands. The fish are usually bought from the West Side Fish Company at a uniform price and sold for one price by all the dealers. The small dealers mix up several kinds of fish in one lot and cry out the price—three, four, or five cents a pound, as the case may be. The dealer that has the strongest voice usually sells the most fish. The stores handle the best quality, some of them selling live fish, the quality being graded down to the poorest as the small dealer is reached, who only has a pushcart to sell from. In the season some of the retail merchants handle cured herrings, including Scotch and Holland. They display the fish in a barrel on the sidewalk, as in fresh fish. They are also subject to examination. Thousands of barrels are sold annually. There are more fresh water fish sold in this market than in any other place in the United States. During the holidays it is not un- usual to see ten thousand people buying fish. They always pay cash and take their purchases with them. Every one interested in the fishing industry should visit this market. It is one of the sights of Chicago. ACKNOWLEDGMENTS. We desire to acknowledge the great assistance given us by the United States Fish Commission in use of their cars and crews in making our distribution, also to uniform courtesy in rendering any assistance possible in our work. The commission has cdoperated with us in every way. To the various railroad managements of the State we are deeply indebted. We have had valuable aid and assistance in our distribu- tion. The use of their baggage cars have been at our disposal. The employés have been uniformly courteous and obliging. The press of Illinois has treated us with consideration, and while now and then criticism of our methods have been used, we have only thanks for space given us in furtherance of our work.

We acknowledge again the debt we owe Prof. Forbes for the use of his valuable list of the native fish of Illinois with keys by Prof. Thos. Large, which we reproduce as an appendix to this report. BY) SUMMARY, As a whole our work will show better results than in former reports. This for several reasons, the principal one being that time has been afforded for plants to show results and the necessities of the work in the various public waters made manifest. The interest taken in the subject alike by the angler and commercial fishermen has largely in- creased and both have been greatly benefited. The enforcement of law has been greatly improved in its scope since the paid warden system has been inaugurated. In fact, the fisherman themselves are fast seeing the importance of proper pro- tection to the fish if any future to their business is to be expected. The out-put, from a commercial standpoint, is large, larger than any previous season, and if proper care is taken will be a matter of annual profit to those engaged in the work and along lawful lines. We hope to be able to. reconcile the conflicting interests we have to contend with, and convince by practical results both the angler and commercial fisherman that both need protection and that both have it, and so far as lies in our power, deal with the question simply as one of economic value, fairly as we understand it, showing no par- tiality, but produce, if possible, the most practical results that time and experience make possible. We have done the best we could with time and means at our com- mand, and leave the results to the people as a whole that we feel it our duty to serve in our official capacity.

CONSTRUCTION OF PONDS AND POND CULTURAL METHODS. (By J. L. Leary.) There has been so much said relative to the construction of ponds and pond cultural methods that it seems but very little additional can be written or suggested along this line that will prove of value to the practical fish cul- turist, yet those of us who have built ponds have discovered mistakes made in construction, as well as experience has shown, errors ia cultural methods and the room for improvement therein. The first great essential to successful pond building is abundance of water. I am safe in making the assertion that few pond building ventures have been made that were entirely satisfactory in this respect. We felt confident the supply of water was ample for all needs only to find after our ponds were constructed, nine times out of ten, that this necessary element of success was inadequate to supply the demand. The course of supply in most cases does not matter so that it is abundant. It may be spring, artesian, taken from some stream, or stored from rain and snow fall. All will answer, though of course the purer and clearer the water the better, as it adds materially to pleasure and success with the work, but bear in mind it is w you think you need. As to pond site it is necessarily secondary to water and must be located as near the supply as possible to avoid the expense of long conduits, ditches or flames. Where artesian wells are the source of supply and so located that heavy rainstorms do not affect them, it does away with long flumes or conduits 42 that otherwise must be used to prevent disaster by flooding the ponds and consequent loss of fish. Most of the eligible pond sites are subjected to this danger of overflow and every precaution should be taken to guard against danger from this source. The most secure place is the center of some low flat, or swamp is not objectionable, with the supply of water from spring or spring branch. I would build my pond or ponds in the center of flat or swamp, making them narrow enough to leave wide spaces on either side. with banks not less than 8 feet on top and 35 feet wide at base. There is one pre- caution often neglected in building ponds, and that is the foundation or bed for your banks. Be sure that all grass. weeds and roots are removed and that the earth is well broken, as this allows the dirt of the banks to assimilate with the foundation, leaving no seam for seepage, which is a source of an- noyance and often develops into a dangerous leak. At the level of water held in ponds I would construct drainways to take off the surplus water of heavy rainstorms. A good plan is to closely observe during heavy rains the amount of water that flows over the intended pond site and by this means you can caleulate very closely the amount of water it will be necessary to divert. Extended flats or swampy places have great advantages for pond-building. One is nearly always assured of an abundant supply of water. and such a site is less hable to danger from overflows than the narrow gorge of the hillside. Then, too, on such a site you are nearly always assured of an abundant growth of aquatic plants which adds much to the value of the ponds. Where artesian water can be relied upon you can build on the most convenient or desirable location. Where it is desired to supply ponds with water by diverting part of a stream, although an abundance of water may be assured at all times. it is too often the most dangerous of all locations, as well as the most expensive. Such ponds are more liable to disaster from overflow than other locations. Either you have an expensive dam to build in order to divert the water. or it is necessary to tap the stream, if a flowing one, some distance above your _ pond site and carry the water through a ditch or raceway. and as most streams are liable to get out of their banks at times this proves a source of danger. The shape of a pond may conform to its situation, making it wide in one place, narrow in another, with symmetrical curves that add much to its. beauty without impairing its usefulness. As to the bottoms nothing uniform is desirable—shallows here and there with little islands covered with aquatie plants also add to the attractiveness and as these shallows may be covered with sand and gravel they make ideal spawning grounds for the fish. If the ponds are for commercial purposes or the rearing of great numbers of young fish is desired these irregularities should all drain to the draw-off which may be by natural drainage or if so situated that this is not feasible can be pumped out with a small gasoline pumping plant, that being about the cheapest power used. This emptying of ponds is only needed for pond cultural work. Should the writer ever build more ponds he will have them of not less than one acre each, with irregular bottoms and long sloping inside banks, the bottoms not so irregular as to interfere with seining but having many shoal places for spawning grounds as well as basking and feeding places for the young fish. While ponds built on the above lines are well adapted to all fresh water fish they would be ideal for black bass, crappie, strawberry bass, and in fact all of the sunfish family. Various methods are suggested and practiced by fish eculturists, each no doubt thinking his own plan best. While good ponds with an abundance of water are the first needs yet the importance of choice brood fish cannot be over estimated. The mistake that many fish culturists make is over stocking the pond and this should be care- fully guarded against. This may vary with climate but taking one acre as a pond basis thirty pairs of fair sized black bass, two and one half to three pounds each, and fifty pairs might not be an extreme. One hundred pairs of the following fish: Crappie, rock bass, strawberry bass, and twenty pairs of channel eatfish or earn. 43 If the output is for commercial purposes some fifteen or twenty nursery ponds or pools will be needed. These should be 8x20x2 feet deep, with con- erete sides and bottoms. The drainage should be perfect allowing’ them to be cleaned at all times. The water supplying these ponds should be carried by piping and each pool provided with a separate inlet and outlet. The re- sult of various experiments made with black bass shows that no young should be transferred to nursery pools under three-fourths to one inch long as they can then take small particle of food prepared or collected for them. Should the brood ponds be well supplied with natural food the young fish should .re- main until they can readily take prepared food and small minnows. The best food for most fish is the flesh of any fish so that it is fresh. My method of preparation is as follows: A white pine chopping block two inches thick as large as desired, a sharp butcher knife. a piece of metal sheet with perforations 1-32 of an inch and a glass or porcelain bowl are the articles required for the work. The tails of crawfish are skinned and the flesh of the other fish skinned and boned, then chopped with the knife upon the board, keeping knife and board wet it can be chopped very fine and screened through the metal sheet into the bowl] and thinned to the consistency of cream with water. This is fed to the young fish once a day or oftener if necessary. The method of transferring young fish from brood ponds I deseribed at some length at our meeting last year. CHIcAGo, Feb. 7, 1905. Mr. S. P. Bartlett. Secretary Board of Fish Commmissioners, Quincy, Ill. Drar Str—I beg leave to acknowledge receipt of your favor of Feb. 3d, and to express my regret that absence from the city has delayed a reply to your first letter. This company is so largely interested in, and in such close sympathy with the work of the Fish Commission, that it is a pleasure to be able to coéperate with you in your arduous duties, and will at any time be glad to furnish any information in its possession that will facilitate your very valuable work. So far as we have been able to ascertain, it is not the custom of the fish dealers, generally, to keep a record of their purchases and sales of different varieties of fish, and there is a manifest and, perhaps, a natural reluctance to furnish information as to the volume of business they transact; but, as nearly as can be estimated from the data we have been able to collect, the sales of fish by wholesale dealers in the city of Chicago amount to about $5,000,000.00 annually. The fiseal year of this company ends with April 30th and as it may be of value to you for purposes of comparison and as a basis on which to estimate the business transacted, to have a summary of fish handled in Chicago by this company, for the year ending April 30th, 1904, I enclose you a copy of same. I am much interested in the subject of uniform legislation pertaining to fishery laws, and should be pleased to take up that question with the mem- bers of your commission at any time that it might be conyenient to you. Cannot something be done to bring about united action on that subject on the part of the Fish Commissioners of the several states bordering on the Great Lakes, and the Fisheries Department of Ontario? Having this in mind, I wrote in December to Mr. N. H. Cohen, president of your commission, asking if he would not favor me with a call on his next visit to the city, and received a reply stating that he expected to be in Chicago shortly after the first of the year; but I assume he has been too busy to make the expected visit. ' Yours very truly, Wo. F. CocHRAN, Manager Legal Department. 44 FISH PURCHASED AND SOLD BY A. BOOTH & COMPANY AT ITS BRANCHES IN THE CITY OF CHICAGO DURING YEAR ENDING APRIL 30, 1904.

INTRODUCTORY NOTE. The following annotated list of the fishes of Illinois is based on the collections and field notes of the staff of the State Laboratory of Natural History from the year 1878 to the fall of 1902. It was pre- pared in the latter year by Mr. Large, while he was in the service of the State Laboratory as its ichthyological assistant. His manuscript was revised for the press in my office, but in a way to make no material change in the substance of his statements, the credit and responsibility for which remains, consequently, with him. The anatytical keys prepared by him, so far as they depart from those already printed, are the results of his personal experience in the identification of Illinois fishes, and are made with a view to dispensing, so far as practicable, with obscure characters and structures difficult of access.

By Thomas Large. As this list is intended particularly for the “man who goes a-fish- ing,” it is desirable that it contain as much information as possible and at the same time be free from all unnecessary technical detail. Although we might wish entirely to avoid scientific names, this is obviously impossible when we remember that at least sixty of our fishes have no common names, and that such names as bass, perch, stone-roller, horny-head, grindle, stickle back, ete., all have more than one application, the same name being applied not infr equently to very different fishes. Of our species about mafia never attain a greater adult length than five inches. These are very commonly taken for the young of other fishes, and are referred to indiscriminately as ‘minnows’ by the unin- formed. It is thought that no apology is needed for directing at- tention to these smaller members of our fish fauna and including them in a list of the native fishes of Illinois. Statements concerning distribution and other data made use of in this list are, with a very few exceptions, based upon collections made in Illinois by the State Laboratory of Natural History, at Urbana. In the use of the keys allowance must be made for individual vari- ations, which are frequently considerable. No determination by the key alone should be thought of as final, but only as leading to a description with which the specimen may be compared. As Jordan’s “Manuel of Vertebrates” (5th to 8th editions) is probably more acces- sible than any other previously published list, comparison with descriptions found there is suggested, and to facilitate such compari- son references to the species numbers of that list are given when the nomenclature has been changed. The nomenclature employed in this paper is that of Bulletin No. 47 of the United States National Museum. a4 ARTIFICIAL KEY TO THE FAMILIES OF NATIVE FISHES OF ILLINOIS.

Ichthyomyzon concolor (Kirtland).—Silvery Lamprey. (5) Taken five times from the Illinois river and once from the Wabash river at Mt. Carmel. Ichthyomyzon castaneus Girard. (4) One example of this species was obtained at Pekin, Ill., April 16, 1880. Lampetra wildert Gage.—Brook Lamprey; Small Black Lamprey. (3) We have records of the occurrence of this species at Cairo, Pekin and Peoria; also found several times by Dr. Jordan in small streams of Illinois. Faminy PoLyopontTip® (THe PADDLEFISHES). Polyodon spathula (Walbaum).—Spoonbill Cat; Spoonbill; Paddlefish. This fish feeds upon the minute animal and plant life of the water. Its snout probably serves as a delicate sense organ. Formerly abundant in all large streams, but now apparently decreasing greatly in num- bers. Now found only sparingly in the larger streams tributary to the Mississippi and in aajacent ponds and lakes, FAMILY ACIPENSERID® (THE STURGEONS). Acipndser rubicundus Le Sueur.—Lake Sturgeon; Rock Sturgeon; Red Sturgeon. The red sturgeon is usually a rather sluggish fish. The color changes with age, the young being drab and the adults green or red. Formerly abundant in rivers and in Lake Michigan, but rarely taken now. Occurs five tines in our collections, being listed from tributaries of the Mississippi and from the Great es, Scaphirhynchus platorynchus (Rafinesque).—Shoyel-fish; Shovel-nose Stur- geon; White Sturgeon. The broad nose and long filament of the tail make this fish strikingly different from the common sturgeon. Not uncommon in the Ohio and Mississippi rivers; frequently taken from the Ohio at Evansville, Ind., by fishermen, by whom it is considered worthless for food and thrown away; rare in the I]linois river. Famity LEpPIsOsTEID® (THE GARs.) Lepisosteus osseus (Linnzeus).—Long-nosed gar. Grows to a length of five feet. Abundant; predaceous, preying upon fish entangled in set nets; pussibly, also, to some extent a scavenger. These fishes undergo certain decided changes with age. Until they reach a length of about 9inches they are provided behind with a slender membranous filament which is a process of the dorsal lobe of the heterocercal tail. This filament has a rapid, wave-like motion, which is continued with but brief interruptions while the fish is at rest. At about the time of the disappearance of the caudal filament the black side stripe, which up to this time extends from the tip of the snout to the caudal, begins to break up into oval spots, while similar oval spots begin to appear on all the fins, on the mid-dorsal line. and on either side of the body. Those on the body vanish in later life, the ones below the lateral line disappearing first. Abundant and widely distributed, being found in all parts of the State excepting Lake Michigan. Principally found in the larger streams, though frequently caught in the smaller ones, where it is found in pools. Lepisosteus platostomus Rafinesque.—Short-nosed Gar. Length 3 feet. In habits like the preceding, though the two species are not usually abundant in the same localities. Difficult to distinguish from the young of the next species. A young specimen, 144 inches in length, has been observed in the act of catching and eating a minnow not much smaller (Meredosia, 1900). Particularly abundant about Havana and Meredosia; absent in our collections from the Rock and Wabash basins. Otherwise distributed about as Z. ossews. Lepisosteus tristechus (Block & Schneider).—Alligator Gar. Length 8 to 10 feet. Said by river men to be a dangeous antagonist; also destructive of netting when caught. Found occasionally in the Illinois, Mississippi and Ohio rivers. a6 FAMILY Amiipa (THE BowFIns). Amia calwa Linnzeus.—Dog-fish; Grindle; Prairie Bass. Of some commercial importance, being regularly shipped from the Illinois River in win- ter. Occasionally sold by fish huckst rs as ‘‘prairie bass.” Considered worthless and unfit for food in thé northern part of the State; in the southern part, under the name of “grindle,”’ replacing the black bass as the most sought game fish, and considered a good table fish. It is a good fighter when hooked and takes bait well. Abundant in sloughs and lakes adjoining the Mississippi and Illinois rivers and in the sluggish streams of southern Illinois. Apparently not abundant northward. FAMILY SILurID® (THe CATFISH). ARTIEICIAL,KEY TO THE CATFISHES OF ILLINOIS. a. Tail forked; color usually light or silvery. -b.

Taken here and there throughout the State in the larger streams tributary to the Missis- sippi; not, however, so abundant as the common channel cat (/. punctatus). Recent exami- nations by Dr. Evermann of specimens of the ‘‘Mississippi Cat’’ show it to be this species instead of Ameiurus lacustris as previously supposed. (Cf. Bull. U. S. National Museum, Vol. III. p. 2789.) Ictalurus anguilla Evermann & Kendall.—Channel Cat: Eel Cat: Willow Cat. Fsobably taken-in our larger streams with other channel cats, but not yet positively recog- nize Ictalurus punctatus (Rafinesque).—Channel Cat; Blue Cat: White Cat. The most abundant of the channel cats. An excellent and marketable food fish. The young stay most frequently in the deep swift water of the rivers and larger creeks. A strong swimmer. Our collections of this species are from 123 localities, distributed throughout the State with the exception of the upper Illinois valley above the mouth of the Fox River, and the Lake Michigan region. It occurs, however, in three collections from Iroquois county. It does not appear to be common southward of the Illinois basin. Ameiurus lacustris (Walbaum).—Catfish of the Lakes. Known from other Illinois members of this genus by its forked tail, larger number of anal rays, and silvery appearance. In these respects it approaches the genus /cfa/wrus, but differs in not having the occipital process articulated with the bones at the base of the dorsal fin. Doubtless not so common in Illinois as hitherto supposed; until lately generally confused with /ctalurus furcatus, under which see note. Lond ‘ or Ameiurus natalis (Le Suer).—Yellow Cat; Yellow Bullhead. Body thick; skin very smooth and thin. Called by fishermen ‘‘greaser” or ‘ ‘greased cat,”’ and readily separated by them from other bullheads. Common throughout the State, except in streams tributary to Lake Michigan, and in the northwestern portion of the Illinois and Fox basins, occurring in the latter region only in collections from Carthage, Hancock county. ‘Taken, in all, from 76 localities. Ameiurus vulgaris (Thompson). Apparently rare in Illinois; possibly not distinguishable from A. me/as. Ameiurus nebulosus (Le Sueur).—Common Bullhead. as fin long; upper jaw projecting; in many specimens the color mottled (var. masmo rvatus). - Taken from 48 localities in Illinois. Apparently less abundant at Havana and Meredosia than other bullheads. Ameiurus melas (Rafinesque).—Black Bullhead. The most common of Illinois catfishes. The young are black in color and swim in schools until about 144 inches long: Abundant throughout the State, with apparent exceptions in the Kankakee, Rock, and middle Kaskaskia basins. Found in 179 localities in all. Leptops olivaris (Rafinesque).—Mud Cat: Goujon; Flat-head. A common market catfish of the Illinois River, being excellent as food. Exceedingly ugly; the head very flat, mouth broad, spines short and thickly covered with solt skin; up- per pant of the caudal white in the young and continuing lighter than the lower portion in adults. ° Thirty localities represented in our collections, all of which are from muddy streams. Not found in the Lake Michigan region. Noturus flavus Rafinesque.—Stone Cat. This fish is usually mistaken fora young bullhead. From these it differs decidedly in habits and also, as do the other stone cats, in the form ofthe adipose fin, which is keel-like, and may be either separated from the caudal by a notch or continous with the upper mar- gin of the latter. This species can usually be separated from the other stone cats by the presence of a white or whitish spot of somewhat crescentic form under the posterior margin of the dorsal. Confined to the north half of the State where it is found under stones in the swifter portions of the larger creeks and small rivers. Not listed from further southward than the Kaskaskia River, in Douglas county: Found in greater abundance in Mackinaw Creek than elsewhere. Our collections are from 37 localities. “Schilbeodes gyrinus (Mitchill).—Tadpole Cat; Poison Cat. (65) _ Astone cat, as shown by form of the adipose fin, but in habit much like a young bull- head, preferring deep. muddy water. The form of the body isin adults much like that of Ameturus natalis; easily separated from the latter by the dark lateral stripe, which ex- tends the length of the body, connecting the angles of the muscle plates. Abundant in the sluggish portions of all streams of central Illinois; common in southern Illinois; somewhat rare in the northwestern part of the State. Schilbeodes nocturnus (Jordan & Gilbert). Body brown, covered with minute dots; no notch between adipose and caudal; 15 or 16 trays in the causal. Length 3 inches. : : ‘ Occurs in ten collections: two from Havana, three frem near Lincoln, three from points on the Kaskaskia River, one from Spoon River near Lewistown, aud one from the -south fork of the Saline River in Saline county. Schilbeodes exilis (Nelson). (61) With much the appearance of Noturus favus, including even the white spot behind the ‘dorsal, but in this fish the crescentic spot is much less evident that in the larger species. From Crane Creek, Freeport, South Henderson and Honey creeks in Henderson county. Iroquois River near Watseka, and creeks in Union county. ’ Schilbeodes eleutherus (Jordan). (64) Length4 inches. Color brownish, with obscure, dark, saddle-like blotches; head broad, flat; barbels not reaching to gill-opening. The distribution of this catfish is peculiar, it being known at present only from creeks near Lincoln, and from the headwaters. of the Kaskaskia and Embarras rivers in Douglas -and Piatt counties. Schilbeodes miurus (Jordan). (63) Known by its grayish color and the four black blotches on the back. : Common on gravelly rapids throughout the Wabash basin; taken once from Cache River -and once from a creek near Pontiac. 58 FAMILY CATOsTOMIDa (THE SUCKERS AND BUFFALOES.)

The common buffalo-fish of commercial fishermen. Mouth large, protractile forward; color brownish olive; opercle % the length of the head. Weight 20 to 30 pounds. Taken from the Rock, Illinois, and Wabash river basins. Common in large streams. Ictiobus wrus (Agassiz).—Mongrel Buffalo. Back not much elevated and not compressed into a keel above, but rounded in cross- section. Distributed about as /. cyprine//a, though not so common. Ictiobus bubalus (Rafinesque).—Small-mouthed Buffalo: Razor-baeked Buf- falo. Depth of body five-elevenths of Jength; back thin; belly thick. Common in large streams and in lakes and in lakes and sloughs. Carpiodes carpi (Rafinesque).—Carp Sucker. (62). Perhaps not rare in large rivers; our collections not, however, as yet carefully studied. Carpiodes difformis Cope. (70) Identified in our Illinois river collections. Probably frequently confused with the next species. Curpiodes velifer (Rafinesque.).—Quillback; Spearfish; Skipjack. (70) Known by the excessive elongation of the first rays of the dorsal fin. Very abundant everywhere, but almost worthless as food. Cycleptus elongatus (Le Sueur).—Black Horse: Missouri Sucker. Formerly abundant in the Illinois river; but now only occasionally taken. The single specimen taken in our collections of the past three years comes from the mouth of Green river. A specimen was obtained also from the Little Fox river, at Philipstown, IIL, in 1882. Catostomus commersonii (Lacépéde).—Common Sucker: Fin-sealed Sucker; Black Sucker. (76) The number of scales varies greatly, giving rise possibly to several more or less distinct varietal forms. * Catostomus catostomus, Of uncertain occurrence in Illinois. * Moxostoma anisurum,; of uncertain occurrence in Illinois. 3 VWoxostoma breviceps, of uncertain occurrence in Illinois. 59 Abundant; found usually in prairie creeks; not yet taken by us in tributaries of Lake Michigan. Not found in our collections from southward of the latitude of the mouth of the Illinois river, with the exception of one collection from near Mt. Carmel, and (singularly enough) ten collections in the Illinois spur of the Ozarks, in the counties of Williamson, Saline, Hardin, Pope, Johnson and Union. ‘Taken, in all, from 68 localities. Catostomus nigricanr (Le Sueur).—Hammer-head; Hog Sucker; Hog Molly; Mullet; Stone-roller. A fish of peculiar appearance; head pyramidal, body subconical; eyes very small; mouth large and sucker like. It is a strong swimmer and is chietly found upon gravelly riffles, where it feeds upon the bottom. As in the case of many other tishes inhabiting similar situations, the back is crossed with dark bars, which probably serve as a means of protection against discovery by wading birds and other enemies. Abundant in rapid, gravelly streams of the Mississippi valley northeastward of a line from the mouth of the Rock river to the mouth of the kmbarras river. In this section we have eighty-four collections of this species, while southwest of this line we have but four, two of these lying very close to the line, viz.: Little Wabash river at Effingham, Spoon river at London Mills, Otter creek in Jersey county, and Clear creek, Union county. Not found in the few collections which have been made from streams flowing into Lake Michigan. Brimyzon sucetta oblongus (Mitchill).—Chub-sucker; Sweet Sucker. The absence of a lateral line serves to distinguish this fish from other suckers. (It should be noted, however, that the young of the next species are without a lateral line also.) The young of this variety are distinguished from adults by the possession of a very black lateral stripe, and may easily be mistaken for minnows. This fish is abundant in the Wabash basin, in the streams tributary to the Ohio river, and in the headwaters of the Kaskaskia; also frequently taken at Havana. It is much less abundant throughout the [llinois valley, not having been taken by us between the Illinois and Mississippirivers. It appears in four collections from the Rock river basin. Minytrema melanops (Rafinesque).—Spotted Sucker: Black Sucker. Readily recognized by the presence of several longitudinal rows of black dots on the scales of the sides. Lateral line absent in the young and incomplete or broken in adults. Abundant in the Wabash basin and in the head waters of the Kaskaskia. One collection from the Saline river at Harrisburg, one from Cedar creek at Simpson, and one from the Big Muddy at Benton. Rareat Havanaand Meredosia and in the northern portion of the State. Not taken between the Illinois and Mississippi rivers. This fish apparently prefers the weedy prairie creeks in situations where it is abundant. Moxostoma aureolum (Le Sueur).—Common Red-horse: White Sucker: Large- scaled Sucker. Scales large; body heavy; head larger than in the next, flat between the eyes and squarish in cross section; nose ending abruptly. Very abundant in streams of all sizes northward; generally found in the black prairie regions. Occurs but six times south of the south line of Shelby county, as follows: Jasper county, N. E.; Fayette county, N.; Wabash county, E.; Wayne county, W. (2); Saline county, S., and Hardin county, center. Moxostoma macrolepidotum (Le Sueur).—Red-horse. Scales large; body more elongate than in the last, tapering from before the dorsal fin for- ward; head rather small, rounded, and bluntly pointed. Common in streams of the northern half of the State. Placopharynx duquesnei (Le Sueur).—Red horse. (85) Not certainly distinguishable from J/. auveolum without removal and examination of the pharyngeal teeth. Occurs in Illinois, butour collections have not yet been carefully enough examined to determine how frequently it may have been mistaken for J/. azeolum.

Mouth inferior and somewhat sucker-like, the lips smooth. Body mottled with black; the fins highly colored in spring, and the males at this season with tubercules on the head and many parts of the body. A tine bait minnow easily taken with a minnow seine in small creeks of running water; very tenacious of life in the minnow pail and on the hook. Abundant throughott the State. More common in small than in larger streams. Oxygeneum pulverulentum Forbes. A single specimen of this fish was taken in 1885 from the Illinois river by Professor Forbes which was so different from any known fish that it seemed necessary to refer it to an entirely new genusand species. As ithas not been since taken, a doubt is suggested whether the fish may not be a hybrid or merely an example of ve y wide variation. There is no warrant however, for discarding the genus and species until breeding experiments show that it is a hybrid, or until the discovery of more species removes the doubt. Chrosomus erythrogaster (Rafinesque).—Red-bellied Dace. A very surprising little minnow, found in the muddier small creeks. The scales are very fine. The color of the female is plain olive, silvery or white beneath, with black dots on the back and narrow silvery and black stripes on the sides; in the males the white is replaced by gorgeous cherry-red, shading to golden forward. The base of the dorsal is red; the other fins and the gill-covers (opercles) are a rich yellow. The red color, while very deep and rich, is peculiarly evanescent, disappearing and reappearing often in a surprising manner. Itis not a distinctly spring coloration as has hitherto been supposed; specimens in our aquari, on the contrary, have shown high color in almost all the summer months and as late as October. Occurs frequently in the Rock river basin and in creeks flowing into the Illinois river in LaSalle county. Has been taken from. creeks near Canton and Farmington, from a spring branch near Wolrab Mills, Hardin county, and from creeks in Union county: also reported from a spring in southwestern Clark county. Hybognathus nuchalis (Agassiz).—Silvery Minnow. A large silvery minnow, with large scales, spindle-shaped body, and pointed head. The lower jaw is thin and hard, with a small hard lump just inside the mouth in front. Dies too quickly to be a good bait minnow. : "i Chiefly found in deep muddy water in large creeks or rivers. Somewhat rarely found in the swift gravelly streams of central Illinois. Abundant to the southeastward, near the Miss- Sian and Illinois rivers. Collected once from a tributary of Lake Michigan, at South icago. 1 “Leuciscus; a genus not certainly known to occur in this State. : ae 2 Couesius peumbeus; a northern form, which may occasionally be found in Illinois. 61 Hybognathus nubila (Forbes). A small fish; in appearance very much like /Vo/ropis heterodon, the similarity extending to the form of the head, body, and fins, and the black stripe on the side which passes through the eye and around the snout. The edge of the lower jaw is hard and sharp and has a percep- pte peeercle on its upper side at the tip. Length rarely greater than 2 inches (to base of caudal fin We have collections of this species from the Ohio river at Cairo, from the neighborhood of Peoria, and from Galena, Carmi and Henry. Pimephales promelas (Rafinesque).—Black-head; Minnow; Fat-head. A short thick fish with very blunt head. The males in spring very dark in color, and with two rows of large tubercules around the snout. Differs from /. xofatws in the thicker body and in the incompleteness of the lateral line. Distributed through the Mississippi, Rock, Ilinois and Kaskaskia basins, usually in the deep holes of small sluggish creeks; also found in the small creeks of Coles county, in the Wabash basin. Taken, ‘in all, from 64 localities. © Pimephales notatus (Rafinesque).—Blunt-nosed Minnow. Differs from /?. promelas in having a rather slender aiigide aa with the lateral line complete; tuberculations and colors not so noticeable as in the preceding Very abundant throughut the Strate, occurring in 338 of ae collections. In the eastern Wabash basin so abundant as to be a nuisance to the collector. Notso numerous in the larger streams. taa-aue . AA.—SHORT-INTESTINED MINNOWS. Semotilus atromaculatus (Mitchill.)—Horned Faced; Creek Chub. A large fat minnow, reaching 10 inches in length. The fine scales on the forward part of the body. the i mouth, and the small barbel on the upper lip near the corner of the mouth, serve usually to distinguish it. It is an active swimmer. feeding on insect larve. worms and small fishies. It is provided with a powerful set of pharyngeal teeth. One of our best bait minnows; easily taken in creeks. Abundant in streams of smaller size throughout the State. Rarely taken in lakes or sloughs connected with the Illinois river. Occurs in 149 of our collections. Opsopeodus emiliw (Hay). The validity of this species is frequently questioned. It differs from O. mega/ops in the complete lateral line and the black spot on the anterior rays of the dorsal. Specimens identified as this species occur in collections from the Illinois river at Havana, the Big and Little Fox rivers in White county, and from French creek at Grayville. Opsopcwodus megalops (Forbes). (158b) A fish with a very small upturned mouth, a black spot on the posterior rays of the dorsal and an incomplete lateral line Delicate lines of black mark the edges of the scales. Occurs in 67 collections, mainly from the Illinois river and from the streams of south- eastern Illinois. Also found at Urbana and near Galena. Never abundant. but found only sparingly, usually in water of moderate depth, with muddy bottom. Abramis crysoleucas (Mitchill).—Golden Shiner; Roach; Bream. (159) This fish is distinguished from all other minnows by the keel on the belly behind the ventral fins. The body is compressed to a thickness of about one-fifth to one-sixth of the cas Mouth much upturned; scales large and rounded on their posterior borders: 13 rays in ana Found in still water, in all parts of the State. Not abundant in collections from the Rock river basin. Occurs in 257 of our collections. Cliola vigilax (Baird & Girard).—Fat-head. This minnow approaches Pimephaies in the fine scales before the dorsal, in the general form of the body, and in not having the first ray adnate to the second of the dorsal, while it differs in having a long intestine and a pale peritoneum. In separating this species from P. notatus we have found that we can usually depend upon the paler color and more obtuse head of C/io/a. The black spot atthe base of the caudal is also usually more distinct than in P.notatus. As in the latter, there is a black spot on the first rays of the dorsal in this species. Found in 170 collections, made throughout the State, with the exception of the Lake Michigan region. Not abundant in the Rock river basin. KEY TO SPECIES OF THE GENUS NOTROPIS FOUND IN ILLINOIS. a.

(98b) Tail forked; mouth not so large as in the next and less oblique. A dark stripe around the snout and through the eye, continued on the sides to the base of the caudal fin as a dusky band which is crossed by numerous darker crescentic or X-shaped marks. Not abundant, although found in 45 localities, distributed throughout the State. Occurs most frequently in the Illinois River and northward. Notropis heterodon (Cope). External appearance so much like that of V. caywga as to lead easily to their confusion. Differs from the latter in the larger more oblique mouth, the lower jaw partaking at its edges of the black of the lateral band. Not uncommon in the streams to the northward of the Illinois River. Widely distributed, but rare southwara. Notropis blennius (Girard).—Straw-colored Minnow. (103) A very plain minnow, wholly without striking color marks. Scales faintly edged with dark brown; a brown, mid- ‘dorsal stripe, which is broader at the base of the dorsal fin than elsewhere. ’ Muzzle decurved; mouth almost horizontal. : A common species, quite regularly distributed throughout the State. Occurs in 174 col- ections. = Notropis seylla (Cope). (105) Moss much like the preceding, but with short, stout body, blunt head and rather small mouth. Rare in Illinois. Specimens in six collections, from central and western Illinois, have been referred to this species. 1 Care must be taken to avoid confusion of cayuga, anogends and heterodon, particularly heterodon, with Aybognathus nubila, 2 N. volucellus; not certainly known to occur in Illinois. 3N. longirostris; not certainly known to occur in this State. 63 Notropis gilberti (Jordan & Meek). A slender species with long head and caudal peduncle. Mouth large, almost horizontal; scales before dorsal, 17. Specimens in seventeen collections have been referred to this species. These collections are from streams in La Salle county and Macoupin county, and from tributaries of the Miss- issippi river west of the Illinois basin. Notropis shumardi (Girard). (106) A fish with a large eye and a large, oblique mouth; the head broad across the top. Occurs from localities as follows: Wabash basin, Cedar lake, Sangamon river and trib- utaries, Rock river at Erie, Illinois river at Havana, and creeks near Canton and Carlinville. Notropis hudsonius (De Witt Clinton).—Spot-tail. A large, pale minnow, with a black caudal spot. Most commonly found in the Illinois river and tributary sloughs and lakes; also, less pomnonly in various parts of the State near the Mississippi river, and in tributaries of Lake ichigan. Notropis lutrensis (Baird & Girard).—Red-fin. This fish is proportionately deeper than any of our other minnows, with the possible exception of Aéramzs, the thickness and depth immediately behind the head increasing with Bae sea opalescent and fine red; spring males highly colored; females duller in color than e males. This species is confined to western and southern Illinois. Its eastern limits seem to be in LaSalle and McLean counties. It is exceedingly abundant in Union county, and is found in sluggish streams as far north as the mouth of Green river. Also found, peculiarly isolated, in Richland creek, Stephenson county. We have taken it in 117 localities. Notropis whipplit (Girard).—Lemon-fin; Steel-blue Minnow. The young of this species are distinguished with difficulty from 4. /wtrensis. The adults are larger and more elongate than the latter, the upper and lower curves of the body being eraue and quite uniform from the tip of the pointed snout to the base_of the caudal fin. oloration less brilliant than in JV. /etrensis; the sides and back marked off into diamond or lozenge shaped areas by blue lines parallel to and near the exposed edges of the scales, these markings being more or less distinctive; a black spot usually present on the dorsal fin; fins of the males in spring a transparent lemon yellow. Taken in 293 collections, from all parts of the State. Most abundant in the rapid, gravelly streams oe the area of the later glacial drift. Less common in the lower Illinois basin and westward. Notropis cornutus (Mitehill).—Horned Dace: Shiner. (113) This species is the gamiest of the minnows, growing tu a length of about nine inches. Recognized by the great depth of the exposed edges of the scales. Spring males much colored with salmon pink, and the head covered with tubercles. Occurs in collections from 153 localities, but is almost wholly absent from collections made between the southern Illinois hill region and the latitude of the mouth of the Illinois river. this area of scarcity corresponding very well with the older glaciated area of southern Illinois. In this region we have obtained but two collections, one from the Little Wabash river, in Clay county, and one from a creek in eastern Wabash county. Notrapis jejunus (Forbes). : A large pale silvery minnow, without conspicious color markings; in the rounded form of the scales agreeing with Aybognathus niichalis. , . ; ; Specimens found in 49 of our collections, made principally in the Illinois River and to the northwestward. Found a few times in tributaries of the Wabash and Ohio rivers in southern Illinois, once in Lake Michigan, and once in Logan county. Notropis atherinoides Rafinesque. The first fish of the genus to be named. A long thin silvery minnow, with long lower jaw and oblique mouth. Lateral line decurved. Specimens from Lake Michigan with a very black stripe on the side. This species and the three following are found throughout Illinois, but are not sharply separated in our preliminary determinations, if indeed, that is possible. Notropis arge (Cope). Differs from JA. atherinoides in the larger eye and almost straight lateral line. Notropis dilectus (Girard). Depth greater and mouth smaller than in \V. atherinoides. Notropis rubrifrons (Cope). Notropis wmbratilis (Girard).—Red-fin. (123). Body short and compressed; very fine scales before the dorsal; anal fin long (rays 11). The males are highly colored; body of variegated bluish, greenish, purple, and opalescent; fins deep red in spring. i , Found everywhere, but occurs most commonly in large creeks and small rivers, being most abundant southward. The several varieties of this species which occur in the State have not yet been carefully discriminated in our collections. 64 Ericymba buecata Cope. Body cylindrical; in general appearance like the straw colored minnow (WN. dlennius). Lower jaw much enlarged, with mucous cavities which appear on the outside as vitreous streaks; eyes directed slightly upwa.d, giving to the fish a peculiar watchful expression. Abundant in the upper Wabash basin; taken also from the Iroquois basin near Watseka. Its occurrence in the latter place due probably to its crossing the low divide near Hoopeston by aid of high water or the changes of water courses through artificial drainage. Phenacobius mirabilis (Girard).—Sucker-mouth Minnow. Mouth inferior; upper lip thickened outwardly and sucker-like; form of body similar to that of the common red-horse. This species and P. scopifer (Cope) are not readily distinguish- able in our collections. The first is described with 48 to 52 scales in the lateral line, the second with 43 to 45, this being the usual basis of separation. Our specimens are intermediate, having from 43 to 50 scales. We have therefore called them collectively 7. miradiiis. Taken in 140 localities, in moderately swift water, throughout the State. Rhinichthys atronasus (Mitchill).—Black-nosed Dace. In general appearrnce very much like the Stone roller (Campostoma anomalum), but with a barbel at each corner of the mouth: the males differing in having a stripe on the side which varies with seasons from crimson to pale salmon-color. Found in rapid streams, widely distributed throughout the State, but nowhere common. Not yet taken from tributaries of the Wabash or of Lake Michigan.

A silvery minnow. ’ Specimens referred to A. Ayostomus have been taken from the Illinois river at Havana and Nees and from the middle fork of the Big Vermilion river on the Champaign-Ford county ine. Hybopsis dissimilis (Kirtland).—Spotted Shiner. In form much like the sucker-mouth minnow (Phenacodius); length 3 to inches. Dis- tinguished readily fram Phenacobtus by the pair of barbels, the form of the lip, and the dark irregular mottling of the back-and sides. Taken from Rock river at Rockford and Dixon, from Tomahawk creek near LaSalle, Spoon river at London Mills, Sangamon river at Decatur, and Embarras river at Charleston. Hybopsis watauga Jordan & Evermann. Like H. dissimilis in many respects; but with a bluish stripe passing around the snout, the stripe bearing 8 to 12 small black spots. Hybopsis amblops (Rafinesque).—Silver Chub; Big-eye Chub. Head large and flattened; eyes directed upward; color silvery. ‘ J Not infrequent in the streams of the Wabash and Ohio basins; taken five times from the middle course of the Illinois river and once from near its mouth; taken also from near the mouth of Rock river, from a pond near Quincy, from the Sangamon river, and-five times from the Kaskaskia river. Hybopsis storerianus (Kirtland). Second in size among the species of this genus. A silvery chub, in appearance and size somewhat like Aydognathus nuchalis. Mouth inferior, overhung by the snout, which bas a peculiar fleshy pad on the end; barbels minute; cheeks vertical; eye high and sitnated mid- eee front and back of head; body tapering forward from the front of the dorsal; head small. 1 1. gelidus; not certainly known to occur in Illinois. 65 _ Nowhere common, though widely distributed in Iinois—from Cairo to East Dubuque and from Danville to Quincy. Not taken from the Little Wabash, Big Muddy, Kaskaskia or Rock river basins, and found at only two points in the Illinois basin—the Illinois river at Ottawa and Crooked creek in Hancock county. Hybopsis kentuckiensis (Rafinesque).—River Chub; Horny-head. A minnow of large size, growing to a iength of 6to 9inches. Body fusiform, stout, about evenly curved dorsally and ventrally; mouth wide; color olivaceous, sometimes bluish; fins frequently tinged with yellowish or red. An excellent bait fish for bass because of its hardi- ness. Confined to northern Illinois, not being found further south than Crab-apple creek in Moultrie county, Salt creek in Logan county, and Flower creek in Hancock county. Couesius plumbeus (Agassiz). This species may be found in I}linois, but has not yet been taken. Similar to Semmoti/us, but with smaller scales. Platygobio pallidus Forbes (147b.)—Misprinted in Appendix. 8th ed., as P. gracilis. A small silvery species, reaching a length of 3 inches; barbel prominent. Differs from the young of /. graci/is, with which it has been confused, in the shorter and broader head, broader interorbital space, wider mouth, and shorter dorsal, anal and pectorals. Found only in the Ohio River near Cairo, from which locality we have 21 specimens, the largest of which are about 3 inches long. FamILy ANGUILLID.Z (THE EELS). Anguilla chrysypa Rafinesque.—American Eel. (218) _ _Ascending rivers from the sea, to which it returns to spawn in the deep water. Common in large streams in spring. Famity Hiopontip. (Tur MooN-EYES.) Hiodon dlosoides (Rafinesque).—Moon-eye. Known from the next by the strong carination of the belly both before and behind the ventral fins.

Belly not strongly carinate before the ventrals: dorsal fin with 12 rays. Occasionally taken from the Ilinois and Mississippi rivers; formerly more abundant. Faminy Dorosomip.2 (THE GiI¥ZARD SHADS). Dorosoma cepedianum (Le Sueur).—Gizzard Shad; Hickory Shad; Skipjack. This tish will readily be recognized by the Elongation of the posterior rays of the dorsal. Very abundant in large streams everywhere, and occasionally taken frém pools in small streams. FamiIny Ciuprerp&® (THe HERRINGS). Pomolobus chrysochloris Rafinesque.--Skipjack; blue Herring. (171) Not common, but only occasionally taken from large streams. Has been obtained by us from the Illinois, Ohio,and Mississippi rivers. Alosa sapidissima (Wilson).—Common Shad. (172) _ Introduced into waters tributary to the Gulf of Mexico, and since taken from the Ohio River at Louisville by Dr. Evermann, of the U.S. Fish Commission. FamiIty SALMONID& (THE SALMON FAMILY.) Coregonus quadrilateralis Richardson.—Round Whitefish. Lake Michigan. Coregonus clupeiformis (Mitchill).—Common Whitefish. Lake Michigan, chiefly in deep water. Argyrosomus artedi (Le Sueur).—Cisco; Lake Herring. (186) Descending the canals from Lake Michigan to the Illinois River.

Cristivomer namaycush (Walbaum).—Great Lake Trout: Mackinaw Trout. Lake Michigan. Salvelinus fontinalis (Mitchill).—Brook Trout; Speckled Trout. _ Attempts have frequently been made to introduce this and other trout into the streams of Illinois, but apparently entirely without success. Trout will not thrive where the tempera- ture of the water at any time exceeds 60 degrees. Famity UmMBriID# (THE MUD-MINNOWS.) Umbra limi (Kirtland).—Mud-minnow. This little fish has a form very much like that of the common dogfish (Amia Calva). It can, however, be at once distinguished from the latter by itssmall dorsal fin, which has but 14 rays, while the number is 42 to 53 in Amia. Usually taken from grassy ponds or muddy creeks, which it apparently prefers to large open waters. Taken in 29 localities throughout the State. Faminty Luciip.® (THE PIKEs). Lucius vermiculatus (Le Sueur).--The Little Pickerel. (214) The little pickerel seldom exceeds 12 inches in length. It differs from our other species (L, ducius) in this respect, and in having the cheeks and opercles fully scaled. = eS Found in grassy prairie creeks and along weedy margins of larger streams throughout the ate. Lucius lucius (Linnzeus).—Common Pike; Pickerel. (216) A voracious feeder, taking fishes of considerable size; the jaws provided with strong back- War eens teeth. Differs from the preceding in having the lower portion of the opercle are. No longer common, but found in all sections of the State. Lucius Masquinongy (Mitchill).—Muskallunge. (217). Sis pias from the preceding two species in having the lower portion of both cheeks and opercle bare. Taken in Lake Michigan; has been said to occur in the lakes of northern Illinois (Nelson.) Famity Paciuim® (THE KILLIFISHEs). Fundulus diaphanus menona (Jcrdan & Copeland).—Top-minnow. Found in Illinois only in the lakes of the northeastern part and in Rock River. Fundulus dispar (Agassiz).—Top-minnow. (208) The body marked with several narrow vertical bars of dark color. Found throughout the State in the quiet weedy pools of smaller streams, or along the margins of larger streams. (Quite rare northwaru. Fundulus notatus (Rafinesque).—Top-minnow. (206) oe ee side and around the snout a large dark purplish stripe, with sometimes a sugges- tion of bars. Common throughout the State in such situations as described for /. dispar. Gambusia afinis (Baird & Girard).—Top-minnow. (211) A tivy top-minnow, with deep body. The males are very minute and scarce. _ Taken from seventeen localities in southern Illinois; two specimens from Havana pro- visionally referred to this species. Gambusia nobilis (Baird & Girard).—Top-minnow. Similar to G. afinis, but less common in our collections. Possibly identical with the pre- ceding, specimens being overgrown examples of that species. - From Johnson county, and from ponds near the Wabash river opposite Mt. Carmel. 67 Famity AmMBLyopsip.2 (Tum BLIND Frsres). Chologaster papilliferus Forbes. The eyes of these fishes are imperfect, and they otherwise show relationships with the blind fishes of the caves, which have not yet been taken in I]linois. Taken only from a spring under a bluff of the Mississippi river west of Cobden, Ill. These fishes have been obtained by only two or three collectors. Mr. E. B. Forbes, the most recent collector, secured about two dozen specimens, which he was able to dip up from among the rocks with atin cup. FAMILY GASTEROSTEID.L (THER STICKLEBACKS). Eucatlia inconstans (Kirtland).—Brook Stickleback. A northern form, not common in Illinois; has been taken from a spring fed slough of Indian creek near Wedron, in LaSalle county. Famity PEercopsip.2 (Tue Trour Percnes). Percopsis guttatus (Agassiz).—Trout Perch; Sand-roller. This peculiar fish is no doubt frequently overlooked by inexperienced collectors, who mistake it fora minnow. Its small adipose fin will distinguish it from all other scaly fishes common in Illinois except the whitefishes, from which it differs in the form of the body and in tue spiny rays of the dorsal, anal and ventral fins. ‘he sides are marked with round dusky spots; color otherwise pale. Found in Lake Michigan, and in the Illinois river from Ottawa to Meredosia. Not very common. Famity APHREDODERID.® (THe PIRATE PERCHES.) Aphredoderus sayanus (Gilliams).—Pirate Perch. This fish, like the last, is frequently overlooked by collectors because of its superficial resemblance to the,sunfishes; called ‘‘half breeds’? by a boy who thought them a cross between sunfish and minnows. Head broader than in the sunfishes; dorsal spine but three or four in number; vent in adults in front of the ventral fin. Taken in ninety-two collections from muddy pools throughout the State. Faminy ATHERINIDA (THE SILVERSIDES). Labidesthes sicculus (Cope).—Brook Silverside; Skipjack. A slender. silvery fish, commonly mistaken by unobserving fishermen for a minnow. The small tuft-like spinous dorsal fin with four rays; soft dorsal with eleven rays; anal elongate consisting of a spine and twenty-three soft rays. ‘The form of.the mouth is peculiar, being prolonged into a sort of beak, the lower jaw curved downward. Abundant near the shores of larger streams and lakes, and frequently taken from the grassy parts of prairie creeks. Generally distributed over the State. FAMILY ELASSOMID.£ (THE PIGMY SUNFISHES). Elassoma zonatum Jordan.—Pigmy Sunfish. A tiny sunfish-like fish without a lateral line and with only 4 or 5 dorsal spines; on the sides 11 dark vertical bands; beneath the dorsal a black spot, and at the base of the caudal a blackish bar. 4 From five Illinois localities, all in the southern part of the State, as follows; Drew pond, White county; Swan pond, St. Francisville; Little Fox river, Phillipstown; Wabash river, Wabash station; and Running lake, Union county.

We have taken it in 220 localities. Apomotis ischyrus (Jordan & Nelson.) (310). Our collection of this species include the original type, from the Illinois river, and two or three others of very doubtful identity. Apomotis symmetricus (Forbes). (309). This species is represented in our collections by specimens from Union county, from Cairo, and from several points on the lower Wabash river; has also been taken in the Illinois river. 69 Leponis garmani (Forbes). A very handsome fish of dark color, with rows of orange-colored spots on the sides; among the most nnished in appearance of all suntishes. Krom Pecatonica river at Freeport, a creek near Warsaw, Round pond at Hamilton, middle course of the Illinois river, creeks near Lincoln, and Big Fox river in White county. Lepomis megatotis (Rafinesque).—Long-eared Sunfish. In this fish the opercular flap is quite variable in size, being 44 the length of the head sometimes in large specimens. Common in clear streams southeastward of,the region of Pontiac, which is the locality of aaa northward occurrence. Not yet taken from the Illinois river or from streams west of it Lepomis humilis (Girard).—Orange-spotted Sunfish. This fish may be easily recognized by the silvery white or pale pink margin of the thin flexible opercular flap; the palest of our sunfishes. A considerable degree of sex dimor- phism is exhibited by this species. The males have orange-colored spots on the sides instead of dark brown, as in the females; measurements of males and females by Mr. W. E. Howard, of Ottawa, Ill., have shown also that in the former the profile is steeper, with forehead con- cave, and that ‘the ventrals are longer, reaching past the vent. Found very generally distributed in the State, except in the upper Rock river basin, Fox river and tributaries, and the DuPage, Desplaines, and Kankakee basins. Not common in the sluggish portions of creeks. Lepomis pallidus (Mitehill).—Biue-gill. The most important of the sunfishes as a food fish. The name blue-gill refers to the blue color usually found on the lower portion of the cheeks. Korm of the body orbicular, a black spot usually present on the dorsal posteriorly. Generally distributed and quite common in the larger streams; apparently not found in the upper portion of the Wabash basin; not very common southward, Eupomotis heros (Baird & Girard). (318b) “4 eee like the preceding, but with a blood-red margin on the opercular flap in the male. Taken from two ponds near St. Francisville, and from a pond opposite Mt. Carmel; a specimen also recorded from Onion creek, at Topeka, III. Eupomotis gibbosus (Linneeus),—Pumpkin-seed; Common Sunfish. (319) Wavy blue lines on the cheeks and opercles; colors very bright, with much yellow; oper- cular flap with red on the posterior margins. ' Abundant in the Illinois basin; especially so to the lakes of northeastern Illinois. Other- mise widely distributed, but nat abundant. Not found in collections from the Wabash or its tributaries. Micropterus dolomiew Lacépede.—Small-mouth Bass; Green Bass: Red-eye Bass. The gamiest of Illinois fishes. Often confounded with the large-mouth bass by the in- experienced, although the separation on a basis of the finer scales in this species (17 rows on cheek and 72 to 80 in the lateral ue) is quite easy. The young may be readily recognized by the white margin of the caudal fin. Found in large clear streams. Nottaken from the Wabash or Kaskaskia basins. Other- wise generally distributed in favorable situations. Micropterus salnoides Lacépéde.—Large-mouth Bass; Black Bass; Green Bass. Scales on the cheeks in about 10 rows; 65 to 70 in the lateral line. The young have a very marked black stripe on the sides and around the snout. The stripe breaks up later into spots, wHich etadually disappear with age, but usually noticeable until the third year, and some- times later. Common throughout the State in the sluggish portions of streams. FamiIty Percip® (THE PERCHES.) “KEY TO ILLINOIS GENERA OF THE FAMILY PERCID. a.

Body in spring with bands of greenish, which become bluish in Jater summer. By far the greater number of our collections of this species come from streams north of the upper course of the Illinois Ry ELANCE the Rock River basin. In addition we have one collection from the Little Fox River in White county,a few from streams in Woecdford county,and some from the Vermillion River and tributaries in Livingston and LaSalle counties. Etheostoma camurum (Cope).—Blue-breasted Darter. Highly colored, ‘‘perhaps the prettiest of fresh-water fishes.” Early collections of this species appear from Peoria, from Union county and from the Saline and lower Wabash basins. A darter which belonged apparently to this species, taken more-recently by Mr. J. P. Bauer, of the U.S. Fish Commission, from a pond near Naples, Ill., was brought into the laboratory at Meredosia and inadvertently lost. before the prelim- inary identification could be verified.

A few specimens have been provisionally referred to this species, but are questionable. Etheostoma obeyense Kirseh. Several specimens have been found in Hardin county which correspond to descriptions of this Kentucky species. Etheostoma squamiceps Jordan. This fish is much like the next in general appearance, with head of similar form and of brownish color. The body is much heavier than is common among darters. Taken in five localities in Hardin county, and once near Anna, in Union county. Etheostoma flabellare Rafinesque. : Body long; lower jaw projecting; mouth large. Color decidedly brownish; males with an orange-colored spinous dorsal, the spines of which are tipped with flesky knobs; fins in both sexes large and barred with black in delicate pattern.
