The present report, “The Crustacea of New Jersey,” is the seventh report on natural history subjects issued by the State Museum. We think this subject will be both interesting and beneficial, as there seems to be no practical work on this subject suitable for the public schools and as reference books for the public libraries. The subject matter of this part of the report has been collected and written by Henry W. Fowler, who has devoted much time to it, or for a number of years. He is also the author of “The Fishes of New Jersey’ and “The Amphibians and Reptiles of New Jersey.’ We feel the present attempt will be a valuable addition to our Museum reports. The demand for these works has been so very great that we have had to use much care in their distribution. The report on “The Insects of New Jersey,” by the late Prof. John B. Smith, of Rutgers College, the State Entomologist, is especially valuable and in great demand. ‘The editions of the Fish Report, and Mammal Report, have been exhausted. All of these volumes on natural history subjects are creditable to the work of the Museum, and the authors as well. VISITORS. The number of visitors to the Museum is continually increas- ing, a fact very gratifying to the Commissioner and the Curator. We have as yet been unable to procure more room, which is so much needed, but then every department in the State House is in need of more room, as the business of the State increases. Soon something must be done to provide more rooms, and we trust the State Museum will soon be provided with the needed room. (9) 10, -REPORT OF NEW JERSEY STATE MUSEUM: The Ackerman Gift. The collection of Continental paper money, presented to the State Museum by Acting Governor Ernest R. Ackerman, during the past year, is one of the most valuable that the Museum has acquired up to this time. This gift is best described in the Trenton Evening Times, of - June 5th, 1911, in the following: Actinc GovERNorR ACKERMAN Gives CoNTINENTAL MoNEy CoLLECcTION TO THE STATE. New Jersey's Museum, Already the Depository of Wealth of Material of Historic Value, is Enriched by Generosity of the Senate President—Gift Highly Praised by Curator Morse and Others. Through the generosity of Acting Governor Ernest R. Ackerman, the New Jersey State Museum, already the depository of a wealth of material of his- toric and economic value, is to be enriched by a splendid collection of Conti- nental paper money. Acting Governor Ackerman has presented the collection to the Museum and Curator S. R. Morse has accepted it for the State. The collection consists of 110 pieces and is one of the finest in the world, as it is complete in every detail as issued to the people, with one exception. It lacks the six dollar note of the tenth issue, dated Philadelphia, September 26th, 1778. This, Mr. Ackerman still hopes to obtain and place with the col- lection. The collection will be mounted in suitable frames for proper display in the Museum and will be known as the Ackerman Currency Collection. This collection was formed by the late Harmon A. Chambers, of Phila- delphia, a collector of notes, who gave a greater part of more than eighty odd years of his life to the collection of paper money, autograph letters and historical matters relating to Pennsylvania. This set, all in fine condition, was the one Mr. Chambers had selected as his best. Acting Governor Acker- man obtained the set some years ago when the Chambers collections were disposed of. Mr. Ackerman has added many choice notes to his collection from the Chambers sale. Acting Governor Ackerman has long been known as one of the most noted living philatelists. His collection of postage stamps of the United States and various foreign countries is superb. While he has long been known as a famous collector of stamps, few of his friends knew that he was also a collector of coins and paper money. Curator Morse said to-day that the value of this collection as an educational exhibit is beyond comprehension, and the State was indeed very fortunate in obtaining it. He declared the gift was another demonstration of the liberality of New Jersey citizens and their desire to make the State Museum one of the finest in the country. Continuing Mr. Morse insisted that the State should no longer delay mak- ing provision for the increased museum accommodations that the great and REPORT OF NEW JERSEY STATE MUSEUM. 11 valuable collection may be properly safeguarded and displayed. He said that he was in touch with other citizens who would, doubtless, contribute collec- tions to the Museum as the final resting place for them if the State provided adequate facilities for properly displaying them. MR. STERLING'S DESCRIPTION. E. B. Sterling, of this city, long a well-known collector, says the Ackerman collection is the finest he has. ever seen of paper money of Continental issue, and the State is to be congratulated upon receiving it. He has written the following description of each piece in the set: Paper money issued by the thirteen original Colonies of North America was first issued by Massachusetts in 1690 followed by Connecticut and New York, both in 1700. inode slislandie yar smeermte cei TZES. aor CLS YL Veil ett. atte wat ae 1723 MUU MRCESR YA rac.

The fight for American liberty began at Lexington, Mass., nineteenth of April, 1775, and on the tenth day of May the second Continental Congress assembled, one of the first acts being to issue paper money of various denomi- nations. DESCRIPTION OF THE NO‘ES. These bills give abundant evidence of the haste with which they were pre- pared, being a combination of type with engraved borders and circular vignette, having a Latin motto above. The bill reads, The United Colonies (with value repeated) at top and bottom; Continental Currency (with value repeated) at each side; in body of note: “This bill entitles the bearer to receive Spanish milled dollars, or the value thereof, in gold or silver, ac- cording to the resolutions of the Congress, held at Philadelphia the 1oth of May, 1775.” Each note numbered in ink, signed by two of the committee, one signing in red and one in black ink. The reverse represents a crude imitation of leaves of various trees, different on each value, with the denomi- nation above: “Philadelphia, Printed by Hall and Sellers, 1775”; below: the whole enclosed in a type border composed of pieces of various patterns evidently selected to add to the difficulty on counterfeiting. The engraved parts were cut on type by an English gun engraver named Smithers. This style of work was adopted so that the bills could be rapidly produced on the ordinary printing presses of the period. The devices selected for the various values (which were retained for the same denominations throughout the series), were very odd and quaint and showed the spirit and earnestness of the committee who furnished the designs and fitted each with an appropriate Latin motto, supposed to cheer the patriots and depress the invaders and tories. 12 REPORT OF NEW JERSEY STATE MUSEUM The designs are described as follows: : One Dollar.—Acanthus plant sprouting up around a basket which is held down by a heavy tile. The motto, Depressa Resurgit, “Though pressed down, it will rise again,’ meaning that although the country had been kept down by a foreign power it would eventually rise in strength and beauty. Two Dollars—A hand with flail about to thresh out a sheaf of wheat. The motto, Tribulatio Detat, “Affliction enriches.” Showing the hard blows they must expect to receive will eventually rebound to their own good. Three Dollars —An aerial flight between a crane and an eagle in which the weaker bird has decidedly the best of it, for while each bird has clasped the other’s claws and the eagle is uppermost, his neck is pierced by the long bill of the crane, making it difficult for him to strike his antagonist. The motto, Exitus Indubioest, “The end is certain.” Four Dollars—A wild boar charging on a spear, motto, Aut-Mors-Aut-V ita- Decora, “Either death or an honorable life.” Five Dollars—A thorny bush which has been grasped by an openhand from which the blood is dropping. The motto, Sustine-Vel-Abstine, “Sustain or abstain.” Six Dollars—Beaver gnawing at a tree, the motto being Perseverando, the motto intending to show that the greatest obstacles can be overthrown by the smaller party. Seven Dollars—A storm, the rain coming down in thick streams over hill and valley while black clouds roll above. The motto, Serenabit, “It will clear up,” meaning all cheer up. Nine Dollars—A thirteen-stringed harp with the motto, Majora-Mil-Nori- bus-Constant, “The greater and smaller ones all sound together.” To give encouragement to the smaller States as well as the larger. Twenty Dollars—The ocean with medieval device of a face blowing on it from out of the clouds. The motto, Vi Concitate, “Driven by force,” the waves of course representing the people, the wind England, which is forcing them to rise up in self-defense. ‘This bill differs from the rest of the series in every respect. ‘The shape is narrower and longer; it has no engraved border, but has a chain linked around the four sides with “Continental Cur- rency” in chain letters at top. It is printed on white paper, soft and porous, while all the other are printed on stiff paper, dull color, with mica and blue silk threads inserted. The left end is marbled in various colors. ‘The reverse is also different, with a mixed border and having a circular vignette at left end, which motto reads, Cessantevento Conquiescemus, “The wind ceasing, we will be cheerful,” representing the sun spreading its rays over the ocean upon which are sailing two ships; also the words “Continental Currency, Twenty Dollars.” This is the rarest note of the series, only 11,800 bills having been printed, while 49,000 of all the other denominations were issued. On the 24th of July, 1775, another million dollars of bills of the denomina- tion of $30.00 were printed, but the date on the note remained as before. The style is similar to the values on the obverse, while the reverse contains the vignettes of both sides of the $20.00 last described. The design on the face of the $30.00 bill is a small tomb with a large laurel wreath on it, with the motto, Si-Recte-Facies, “If thou shall do well.” A wreath on an altar REPORT OF NEW JERSEY STATE MUSEUM. 13 which is supposed to represent Congress. ‘This issue is signed by two of the following twenty-eight persons, one with red and the other with black ink: Thomas Barlow, Thomas Barclay, John Bayard, Andrew Bunner, Thomas Coombe, William Craig, Daniel Clymer, Judal Foulke, Isaac Hazelhurst, William Jackson, Robert S. Jones, Fred Kuhl, Thomas Lawrence, Ellis Lewis, Mordecai Lewis, John Mease, Samuel Meredith, George Miffin, James Milligan, Anthony Morris, Luke Morris, Samuel Morris, John M. Nesbit, James Reed, Robert Roberts, John Shee, Joseph Sims, Robert Tuckniss. The second series of notes is of the same design and values from one to eight dollars, the total issues being the same as the first series, or three million dollars, and are dated Philadelphia, November 209, 1775. The third series, dated Philadelphia, Feb. 17, 1776, introduces four new values, which are confined to this issue only. The shape is upright instead of oblong, and the denominations %, %, % and % of a dollar. The design is the same on all, that of a sun dial with the word “Fuglo” in the half circle, and “Mind your business” below. ‘The device is familiar to all coin collectors as that of the first American cent, while the reverse is equally well known from being found on the Continental pewter dollar. The thir- teen-linked chain, bearing the name of a State, encircling a ring in glory inscribed “American Congress,” in centre “We Are One.’ The designs of the fractional notes are far superior to those employed on the higher values. There are three designs of francs to each value, which are marked respec- tively, A, B, C. They were signed only once, and that in red ink. All this series contain the mica and silk threads in paper, a safeguard for all Con- tinental bills. The fourth, fifth and sixth series contain nothing noteworthy, other than the one dollar bill is omitted from the fifth and sixth and the $30 take their place. The dates are May 9, 1776; July 22, 1776; November 2, 1776, respectively. The seventh series is noteworthy from the fact that they are dated at Baltimore, February 26, 1777, instead of Philadelphia. The values and designs remain the same. The eighth series is the first on which the name is given as the United States, the old designation of United Colonies having been discontinued on the four series issued since the glorious Fourth, when it was officially adopted. ‘This change in name was effected by a simple alteration of the border, except in the case of the $30, where new top and bottom pieces were prepared. The set was issued at Philadelphia and dated May 20, 1777. The ninth series, dated at Yorktown, April 11, 1778, are the most interest- ing of the entire series from the fact of their great rarity and for the sub- stitution of the $20, $30 and $40 bills (the latter value being the only one in the entire series with an English motto) in place of the regular $1, $2 and $3 bills. The borders have been replaced by new ones of less elaborate designs and the vignettes re-engraved in an inferior manner. Counterfeits of this rare issue are met with, and from their frequency at the period and together with the eighth series, were withdrawn from circu- lation on this account. 14 REPORT OF NEW JERSEY STATE MUSEUM. The design on the $40 bill is an altar with fire surrounded by thirteen stars, with the All-Seeing Eye above, with “Confederation” below on ribbon. This is the only instance where the motto is given in English. The tenth series is dated Philadelphia, September 26, 1778, adding two new values, $50 and $60, this issue consisting of the following values: $5, $6, $7, $8, $20, $30, $40, $50 and $60. The engraving is the same as used for the Yorktown set. $50 represents an unfinished pyramid, consisting of thir- teen layers of stone, representing the thirteen States. The motto, Perennis, means “Everlasting,” a most appropriate device. Reverse, two arrows pointed upwards with one crossed. Sixty Dollars—The world floating in the firmament, with motto Deus Regnat Exultet Terra, “The Lord reigneth, let the earth rejoice.” Reverse, a bow without arrows, representing all is spent. The eleventh and last issue of Continental bills closed the series by giving the name of the government in full, “The United States of North America,” omitting the name of the city where issued. The date is January 14, 1779. As a safeguard against counterfeiting an oblong band in the left border and a section of the vignette is printed in red. No counterfeits of this series are found from the fact that the depreciation was so great that they were not imitated to any great extent, if any. The values are as follows: 1, 2, 3, 4, 5, 20, 30, 35, 40, 45, 50, 55, 60, 65, 70 and 80 dollars. Thirty-five Dollars—A field with a plow in the foreground, three trees and cloud above. ‘The motto, Hine O. Pes, “Hence Our Wealth,” calling attention to the fact that agriculture is the sure source of wealth. Forty-five Dollars—Two beehives under a shed, bees at side and in front. The motto, Sic Floret Respublica, “Thus flourishes the Republic,” teaching that if they would prosper they must follow the example of the bees. Fifty-five Dollars—The sun shining on a landscape and driving the black clouds away. The motto, Post Nubila Phoebus, “After the clouds comes the sun.” Sixty-five Dollars—A hand from heaven holding a pair of scales over the earth. The motto, Fiat Justitla, “Let justice be done,’ calling attention of all to the fact that their cause is just and that they must place their re- liance in God. Seventy Dollars—A single tree growing on a hilltop. The motto, Vim Procellarum Quadrennium Sustinnit, “For four years it has sustained the force of the storm.” The tree represents the United States, which, after four years of war, still remained strong and a sign of full encouragement for the future. Eighty Dollars—A large strong tree, firmly rooted and its branches filling all the space above. The motto, Et In Secula Se Culorom Florescebit, “It will flourish forever and ever.” ‘The last and highest denomination of the series. This prophetic announcement certainly has proven to be true. While the first emission was dated May 10, 1775, the notes were not actually in circulation until August following. Till the issue exceeded nine millions, the bills passed at their nominal value. The depreciation afterwards was very great. REPORT OF NEW JERSEY STATE MUSEUM. 15 The rate of exchange for hard money in Philadelphia from January, 1777, was 1% and in May, 1781, was soo. On the 31st of May, 1781, the Con- tinental bills ceased to circulate as money, but were afterwards bought on speculation at various prices, from four hundred for one up to one thousand for one. The value ‘for Continental paper money was not the same in different parts of the country. The exchange was, for example, December 25, 1779, at thirty-five for one in New England, New York, the Carolinas and Geor- gia, and at forty for one in Pennsylvania, New Jersey, Delaware, Maryland and Virginia. As late as May, 1781, speculations were entered into at Phila- delphia to purchase Continental money at two hundred and twenty-five for one and sell it at Boston at seventy-five for one. It is worthy of remark that the depreciation of Continental money never stopped the circulation of it. As long as it retained any value at all it passed quick enough, and would purchase hard money or anything else as readily as ever when the exchange was two hundred for one and when every hope or even idea of its being ultimately redeemed at nominal value had entirely van- ished. According to an estimate by the Register of the Treasury of 1790, the issues of the Continental money amounted to $359,547,027.25 from 1775 to 1781, when the circulation ceased. The Continental money was in its true character a simple evidence of debt due by the Government, when the Continental money was first issued. An expression of doubt as to its value involved suspicion of disaffection to the cause of the country, As the issue increased the prices of goods neces- sarily rose, but this was attributed to combination of the merchants to raise prices of their merchandise and to sink the value of Continental money. They were called Tories, speculators and many other hard names, and their stores were forcibly broken open and their goods sold at limited prices by committees of the neighbors. On January 11, 1776, Congress resolved that whoever should refuse to receive in payment Continental bills, should be declared and treated as an enemy of his country and be precluded from intercourse with its inhabitants ; in other words outlawed. Other various acts were passed from time to: time during the next five years to force the people to take Continental money. Many thousand fam- ilies of full and easy fortunes were ruined by these fatal measures, and the loss mostly fell on the Whigs, as it was in their hands when the paper depreciated. The Tories, who had no confidence in it from the beginning, made it a rule to part with it as soon as possible. Certain compulsory measures of the Executive Council of Pennsylvania designed to support the credit of the Continental money and of the State bills gave the fatal blow to the system in May, 1781. C. J. Baxter, Ex-President of the Museum. When Dr. A. B. Poland, now City Superintendent of Newark Public Schools, resigned as State Superintendent of New Jersey 16 REPORT OF NEW JERSEY STATE MUSEUM. to take a position in New York city, Dr. Charles J. Baxter was appointed to the position of State Superintendent by Governor Griggs on March 24th, 1896, and was at once confirmed by the Senate. Mi Dr. Baxter was elected President of the New Jersey State Museum Commission at its first meeting, and has held that office up to July ist, 1911, when he went out of office as the State Superintendent by act of the Legislature, which act abolished the office of State Superintendent, and created a new depart- ment with a Commissioner of Education at the head, and a new State Board of Education of eight members instead of twenty, as before. As President of the New Jersey State Museum Commission, Mr. Baxter took an active part in making the Museum a success, and he was always a very strong advocate of it. Mr. Baxter will be greatly missed. Dr. Calvin Kendall, the new Commis- sioner of Education, was elected President of the Museum Com- mission at its last meeting, and he is deeply interested in all matters that advance the cause of education.

J., who died February 23d, tort, in his will bequeathed ‘“‘to the New Jersey State Museum at Trenton his collection of minerals, fossils and other curios, as they think worth a place in this collection.” This collection was accepted by the Commissioners and a letter of thanks sent to the heirs of Mr. Livezey. One of the attaches of the Museum was sent to Mount Roya! to pack and ship the collection. It was placed in a cabinet until a proper location can be made in the Museum. The collection consists of nearly 1,500 different specimens, mostly small ones, such as Indian relics, shells, petrified wood, minerals, etc., and is a valuable addition to the Museum. The Gross Collection. The botanical collection of C. A. Gross, which was pre- sented to the Museum by his children two years ago, was another valuable gift to the State. It is a collection of the flora of southern New Jersey. It will scon be ready to be placed on exhibition in the Museum. REPORT OF NEW JERSEY STATE MUSEUM. 21 ° Memorial to Dr. E. B. Voorhees. Former Commissioner of the New Jersey State Museum. (Taken from Memorial by Dr. W. H. S. Demarest, President of Rutgers College, New Brunswick, N. J.) Edward Burnett Voorhees was born June 22d, 1856; he died June 6th, 1911. He was graduated from Rutgers College with the degree of Bachelor of Arts in 1881, and in 1goo he received the degree of Doctor of Science from the University of Vermont. He became Professor of Agriculture in Rutgers College in 1890 and Director of the State and College Experiment Stations, re- spectively, in 1893 and 1896, which office he held until his death. He was a classical student, as we have familiarly used the term through the years; he took the Arts degree, which demanded for its conferring Latin and Greek; and from such classical training he passed speedily into the research field of scientific agriculture and so to his eminent place in agricultural education; standing thus as one of the many high examples of great distinction in scientific and technical profession built from the broad founda- tion of a classical culture. As a graduate, through thirty years he gave to his college a loyal and energetic love. After but a single year’s service elsewhere, in 1882 he came back to take up life and work within the walls where he studied, and there his home and his work remained to the end. It was inevitable that out of his marked ability and success in his chosen line of study and service he should become Professor of Agriculture in the college where his experiment, research and direction was main- tained. ‘Thus he entered the faculty in 1890, succeeding the lamented Dir. George H. Cook. For twenty years Dr. Voorhees, as Professor of Agriculture, fulfilled and advanced in Rutgers College this line of instruction with a power and aptness com- manding wide recognition. And especially in the last half dozen years did he, as head of the department, with the administration of the college, successfully promote large things for this field of learning, chiefly perhaps in leading the State to the establish- ment of the Short Course in Agriculture. 22 REPORT OF NEW JERSEY STATE MUSEUM. Out from the College and Station-Centre his work and his personality pervaded the State and even played their part in the life and progress of the nation. In the most material way the resources of the State were in far degree developed by that which came forth from his brain and hand. It was his custom to go ceaselessly about the State, and his ‘visits to communities and clubs were a vigorous campaign of scientific truth. ‘Thus not only were great and continuous material results achieved, but, as well, a singular personal influence was created and wrought widely for good. Like Dr. Cook, he became widely known throughout the State, and throughout his wide acquaintance his character and work were a strong influence for the general good. It is difficult to measure the reach of such a | life, but it is safe to say that there are few men in the life of the State who have been more warmly regarded, more surely trusted and more plainly followed than he. This singular hold upon the people and service of them was recognized in many appointments by the State itself and by organizations within its bounds. Such official places were not only the consequence of the unusual activities and acceptance, but the vantage point for still more effective work for the public good. Thus he was President of the State Board of Agriculture for many years, and frequently served on boards and commissions charged with the care of related interests. His counsel was always sought and respected; he it was who largely shaped policies, formulated plans and guided the movements of such enterprise. It is plain that in all this distinguished relation to the State he was standing in high connection with general scientific move- ments and with the welfare of the world at large. He was a student, and the products of his scholarly thought and research were the enrichment of the worldwide field of learning. He was the author of books which became conspicuous promoters of the cause he represented and authorities in their special lines. In 1902 he received the Nichols Research Medal for the best paper containing results of chemical research submitted to the Ameri- can Chemical Society Journal. He was a member of various learned societies, and read papers before them, both in this land REPORT OF NEW JERSEY STATE MUSEUM. 23 and abroad, where he was accorded the honors due an eminent scholar and _ scientist. In the midst of engrossing work, surrounded by constant public demands, and challenged by the material problems of science, he found the time and had the spirit to enter steadily and strongly into the life and oversight of the church. He was a man of the fear of God and of faith. Born in a Christian home, trained in the nurture and admonition of the Lord, confessing his Lord in his maturity, he treasured through life the gospel of Christ and honored His church as the pillar and ground of the truth. Dr. Voorhees was diligent in business, fervent in spirit. A supreme characteristic was his devotion to work, his incessant- ness in the affairs of his vocation. His interests were many and wide. His chosen calling brought him into manifold relations, many communities of men, many places of responsibility. He was ambitious and confident and courageous. His heart, we say, was in his work; the joy of the pioneer and of the conqueror was his: the mastery of the earth beneath his feet, was a thing of the spirit as of the brain and hand. His was not a long life, but it was crowded full. He served his generation and his works do follow him. Dr. Voorhees was a member of the Commission of the New Jerey State Museum from January 17th, 1901, to the time of his death, June 6th, 1911. His interest in the success of the State Museum was always shown by his work for it. For this success, we owe much to his interest and suggestions. No one could be associated with him in any way without profiting by the privilege of the association. The Curator of the Museum feels that he has lost one of his best friends, and the State one whose place it will be hard to fill. S. R. Morse, Curator. 24 REPORT OF NEW JERSEY STATE MUSEUM. Memorial to Mr. William H. Werner. William H. Werner, a taxidermist of ability, has recently passed away in his seventieth year. His collection, all his own handiwork, valued at $50,000, has been exhibited on the Atlantic City boardwalk, known as Wonderland. He was loved and ‘respected by all who knew him. Fortunes may be made and lost. Fame may come upon the worthy and depart. There is but one thing that lives on through years, and that is character, the recollection of the kind sympathies, the loyalty, sincerity and integrity of the man who has gone. The thoughts of these good traits become enshrined in the minds of his fellowmen. The memory of these may sleep with one’s consciousness, or may fade and be forgotten, but the mention of his name summons them back to life. This sentiment is inspired by the sad demise of Mr. William H. Werner, of Atlantic City, N. J., which came as a distinctive shock to his relatives and friends, who were proud to call him friend. Mr. Werner, through a long life of usefulness, had endeared himself to a wide circle of friends, who deeply deplore his loss. He was born in Nazareth, Pa., seventy years ago, and began the work and research of taxidermist at an early age. Being a naturalist, he combined the two talents, and built up the fine collection of birds, etc., which was for many years exhibited on the Boardwalk, Atlantic City, known as “Wonderland.” This collection represented his life work, in which he had his whole interest. Experts of this country and abroad have pronounced the collection one of the finest of private collections in the world. Every animal and bird in the collection was hunted down, killed and stuffed by Mr. Werner himself. No better evidence of the high regard in which Mr. Werner was held could be shown than upon the occasion of his funeral when the large concourse of mourners, coupled with the many beautiful floral offerings, was a striking testimonial to the memory of this estimable man. REPORT OF NEW JERSEY STATE MUSEUM. 25 With the death of Mr. Werner, the New Jersey State Museum loses another of its best friends and workers, the others being Prof. Apgar, in charge of the Department of Birds and Botany; Dr. E.. B. Voorhees, one of the Commissioners, and Dr. John B. Smith, the head of the Department of Entomology. Mr. Werner has been the State T'axidermist since the creation of the State Museum in 1895. He has mounted and arranged most of the birds and mammals in it. Before coming to our State he prepared the Pennsylvania State exhibits and those of the Lehigh University. At the St. Louis and Jamestown Ex- position he arranged the birds and mammals for the exhibits. He has always been devoted to the success of the Museum, and was a friend who was true, honest and lovable. The Museum and the Curator have lost a friend whose place cannot be filled. His work will be his monument when we shall all have passed away. Sizas R. Morse, Curator. Memorial to Dr. John B. Smith. Dr. John B. Smith was born on November 21st, 1859, in New York City, of German parentage, and was educated in the public schools. He was admitted to the bar in 1880, and prac- ticed law in Brooklyn between 1880 and 1884. He was greatly interested in insects, joined the Brooklyn Entomological Society of that time, and became editor of the bulletin of that society. This publication he afterwards developed into a periodical known as “‘Entomologica Americana,’ which became an import- ant vehicle for the publication of smaller papers and notes. In 1884, he was made special agent of the Division of Entomology, U. S. Department of Agriculture, and for two years did field work, especially upon insects affecting hop and cranberry. ‘This was his first introduction to economic entomology. In 1886 he was made aid in the Division of Insects of the U. S. National Museum, and held this position until he was appointed to his final position in New Jersey. During the four years he was con- 26 REPORT OF. NEW JERSEY STATE MUSEUM. nected with the National Museum, it is true that his work was all of a systematic character and that he did no actual work in economic entomology, but he was a member of the En- tomological Society of Washington and was constantly asso- ciated with the men of the Division of Entomology, U. 5. Department of Agriculture, and followed their work intimately and discussed it with them; so that he really lived in an atmos- phere of practical work. With the founding of the Association of Economic En- tomologists, an organization which has made a great impress on practical entomology, not only in this country but in other parts of the world, Dr. Smith was made secretary of the asso- ciation and held this office for two years. He was made second ' vice-president in 1893, first vice-president in 1894, and president in 1895. His address as retiring president was entitled “En- tomological Notes and Problems,’ and was delivered August 27th, 1895, at Springfield, Mass. It was a thoroughly practical address, dealing with all the phases of the work which the then new body of officials were engaged upon. Dr. Smith’s bibliography covers hundreds of titles. His in- dustry was enormous. He not only made his office a noted one for its practical work, but he maintained all through his career an active interest in every phase of entomological research. He published, for example, two great catalogues of the insects in New Jersey, and very many systematic papers upon that Lepi- dopterous Family, Noctuide. His latest work, and that which perhaps brought him the most fame, was that with the New Jersey mosquitoes. He was the first entomologist who realized and who proved that the banded- legged mosquitoes of the Atlantic coast must differ widely in habit and mode of life from the rain-barrel mosquitoes and the woodland mosquitoes of the interior; and he found that these salt-marsh mosquitoes breed in the salt marshes, and that their eges are not laid in the water but on the mud, and that they fly a distance of from thirty to forty miles. These claims seemed revolutionary to earlier students of mosquitoes, but he proved his case beyond doubt and succeeded finally in securing a large REPORT OF NEW JERSEY STATE MUSEUM. 27 appropriation from this State, and in demonstrating that it is possible at a comparatively slight expense to control even these wild, salt-marsh forms. Dr. Smith’s death is a great loss to the State of New Jersey and the American economic entomology.* Dr. Smith became associated in the work of the New Jersey State Museum at its creation by an act of the Legislature in March 26th, 1895. He was selected to have charge of the Entomological Department as soon as the commission was organized. The curator wrote to the Division of Entomology of the U. S. National Museum asking it to recommend a man ~ to take charge of this department. This was the reply: “You have the best man for the work in your own State, Prof. John B. Smith, of Rutgers College. There is no better.” This statement proved true. My work with Dr. Smith has been one i the most delightful and profitable of my life. He has supervised all of the insect collections in the Museum, and the collection is among one of the best. The collection he prepared for the Museum “How to Exterminate Mosquitoes,” shown at the St. Louis Exposition, was the first of its kind ever exhibited at an exposition. It was a wonderful exhibit and was studied by entomologists and others from all parts of the world. It is now a part of the New Jersey State Museum. Dr. Smith wrote the part of the Museum Report on “The Insects of New Jersey,” for 1910, which is one of the valued Museum reports. We feel that the Museum, the State and the world has in his death lost one of their best friends and workers. The work he has done for the State, country and Museum will ever reflect his usefulness.

Na ; } rte be oe bie > PREFACE: The animals known as the Crustacea, embracing the forms commonly called water-fleas, fish-lice, barnacles, beach-fleas, pill- bugs, wood-lice, shrimps, prawns, lobsters, crawfishes and crabs, are here treated with reference to those now known to inhabit the limits of the State of New Jersey. These creatures are in many ways of the greatest importance to man, not only as a number of them are valued for food, but their vast numbers, in many cases virtually myriads, form food in turn for other valued animals, and therein largely contribute to the maintenance of certain fisheries. Little is yet known of their habits, except in most casual or cursory ways, outside, perhaps, of the two most important economical species, 7. e., the lobster and the blue crab. When extensive researches into the animal behaviour and other studies are prosecuted, possibly better means may be discovered to allow human agencies to improve commercial possibilities. The great fecundity of many species is the only apparent offset to the murderous ravages of hosts of predatory enemies, to which the young appear ever subjected. While, therefore, the present account deals thus indirectly with the economic problems in- volved, such an attempt as is here outlined will at least assist, it is trusted, by defining and illustrating these interesting and valuable animals. | The faunal relations are such as would result from purely. local conditions in the case of fresh-water forms, but in most in- stances, as the Crustacea are such wide-ranging animals, in fact many being world-wide in their distribution, but little can be said of their geographical features. However, among many of the species recorded, but little doubt attaches to most records. A species may be frequently known since from one end of its range along the Atlantic coast, at least within its faunal region, oil 32 PREFACE. to the other. In many cases I have been able to confirm old records by the examination of the original material, as well as add new collections not studied before. In the method of sequence the lowest and most generalized groups are treated first, the more specialized following. The system of arrangement is largely that of Miss Mary J. Rathbun in the Crustacea of New England. In framing the higher groups as orders, suborders, families, tribes, genera, etc., all avail- able information, from whatever source pertinent, has been utilized, and is, therefore, the work of various writers. This may be explained by the fact that in the Crustacea many writers have confined themselves to a single or but a few groups, a prac- tice often followed by entomologists and others. Thus great differences in terminology as applied to really the same organs become evident. I have not attempted to eliminate this feature, but have tried to use such characteristic appellations as are in use for each group of animals. It may also be well to note the various more important general works briefly which have been utilized in the present groupings. The Phyllopoda are treated in the exhaustive monograph by Dr. Packard in 1883. The Ostracoda will be found in the ex- haustive account by Messrs. C. L,. Herrick and C. H. Turner in 1895, though several important papers on special groups have ap- peared since. The parasitic Copepoda have recently been studied by Dr. C. B. Wilson, the fresh-water forms by Herrick and Forbes, and the free-swimming forms have been studied from the Gulf Stream by Professor W. M. Wheeler. The Cirripedia have been studied as early as 1851 by the masterly hand of Charles Darwin, and recently the stalked forms have been treated by Dr. Henry A. Pilsbry. The Amphipoda, in the discussion of the Wood’s Hole region, have been studied by Dr. S. J. Holmes. The Isopoda have been monographed in the exhaustive and well illustrated work of Miss Harriet Richardson. ‘The Decapoda have been studied and outlined in the article under the Synopses of North American Invertebrates in 1899 and 1903, by Miss Rathbun. It may also be stated that the Amphipoda and Isopoda, besides the Macrura, are included in similar fashion, PREFACE. 33 the first by Dr. Holmes, the second by Miss Richardson, and the latter by Dr. J. S. Kingsley. Further, the article on Crustacea in their text-book on Zodlogy, by Messrs. T. J. Parker and W. J. Haswell, and the handy little history of the Malacostraca, by the Rev. T. R. R. Stebbing, are largely drawn from. In drawing from these works the accounts have been freely modi- fied to suit such purposes as appeared desirable. The descriptions of species are drawn from New Jersey ma- terial, whenever possible, and if no specimens are available, the compiled description is credited to the particular author from which it is taken. Often I have followed the sequence of char- acters, etc., quite closely in cases where recent monographs treat of groups, but in every case most of the characters have been verified at the time of writing the description. The value of such models seems to be in that they afford room for the extent of variation noted. Special mention of thanks is here given, collectively, for the works referred to above, besides numerous others, which, on ac- count of the many titles, would be out of place if listed in this connection. I am indebted to the Academy of Natural Sciences, of Phil- adelphia, for the use of the collections and books. The collection of this institution contains some of the most interesting historical specimens dealing with the carcinology of New Jersey, and safe to say many, if not all, of the indigenous crustacea. Within the past few years I have succeeded in adding a number of interest- ing specimens myself from various localities in the State, as well as from adjacent States. To many friends and associates, who have been mentioned elsewhere, I am indebted for the acquisition of material, assist- ance in collecting, or notes, etc. Dr. Henry A. Pilsbry has kindly given me assistance with the barnacles. Mr. Witmer Stone has offered notes and records of his collections made at Point Pleasant. Dr. Richard J. Phillips has presented me with material and notes from Corson’s Inlet. Dr. Benjamin Sharp, one time active in local, as well as general, carcinological work, 3 MU 34 PREFACE. has kindly placed his entire card catalogue of the higher groups in my hands. To many others, whose favors I cannot definitely recall, expression of thanks is also cheerfully granted. The writer is under obligations to Mr. Silas R. Morse, Curator of the State Museum of New Jersey, who has en- couraged and assisted in every way towards making the present work possible. The figures given are mostly my own, made in water-colors from fresh specimens, where possible, and, if not, with pen and ink sketches from preserved material. Where necessary, figures have been copied from other writers, and are duly credited as such. All the Entomostraca have been drawn by myself. Except in the case of the barnacles, and where necessary to copy from other writers, I have modified the figures to suit present purposes. Finally, the work is offered not only as the first comprehensive attempt at describing and illustrating the Crustacea now known from the limits of New Jersey, but equally as a contribution to the knowledge of most of the Crustacea of the Middle Atlantic States, of which New Jersey is the integral unit in this respect. For this reason it has been necessary to consult the Crustacean fauna of the adjacent Atlantic States region. With this end in view, an appended list will follow the discussion of the New Jersey species, and thus united the two will form a complete check-list. It is, perhaps, scarcely necessary for me to state that the principle followed in nomenclature is priority, with actual type designation either originally or by the first reviser. Though at best inevitably faulty, our work, it is thought, will be of great service in future studies. Therefore, should it arouse sufficient interest to produce other and more perfected accounts, then the writer believes his purpose will be accom- plished. HENRY W. FOWLER, Academy of Natural Sciences of Philadelphia. October 29th, 1912. Crustacea of New Jersey. BY HENRY W. FOWLER. HISTORY. The history of the Crustacea of New Jersey, and in fact of North America generally, may be said to begin with the labors of that distinguished veteran naturalist Thomas Say. These are combined in the modest little paper, extending in several parts through the first volume of the Journal of the Academy of Natural Sciences of Philadelphia, published in 1818, and en- titled “An Account of the Crustacea of the United States.” This work is the very foundation of North American carcin- ology. While embracing but a few of the more conspicuous forms now known to occur, in the present instance the work is particularly pertinent, inasmuch as many, if not most, of the species were described from the Great Egg Harbor Bay region in the State of New Jersey. The figures accompanying were made with the characteristic daintiness of C. A. Le Sueur, another distinguished colleague of Say’s. The region of Egg Harbor Bay was long famous as a point of interest to early local naturalists, and this has been increased by subsequent ones wish- ing to review the work of their predecessors. As most of these gentlemen were interested or connected in some way with the Academy of Natural Sciences of Philadelphia, most of their material found its way into the museum of this institution. Later they were also induced to visit other regions of the sea- coast, and thus more representative faunal collections were accumulated. As these are more or less complete from certain (35) 36 REPORT OF NEW JERSEY STATE MUSEUM. localities, with respect to the more conspicuous or higher forms, they will be mentioned in sequence with the few published accounts. Of the latter only several short ones refer exclusively to the carcinological fauna of New Jersey. Some of Say’s specimens are still extant, though most of them in very poor or only fragmentary condition. ‘This is largely due to the old method of preparation, when only dried specimens, mounted on cards, pins, or in trays, were in vogue. Other data than a general locality and the donor’s. name was exceptional. After being exposed to the light, dust and various temperatures, besides the wear and tear due to moving them about, not to speak of insect pests, it is remarkable that any have persisted to the present time. All recent collections are now fixed as wet or alcoholic preparations, and well housed from the ravages of light, dust and evaporation. The old habit of drying Crustacea likely grew out of the idea that while similar in many funda- mental characters to insects, with which animals they were in fact considered, it was thus thought necessary to mount them on pins. Possibly it was also thought that they may be ex- amined with greater facility, as well as save expense in the use of spirits. Among other early collections made in New Jersey are those of Dr. R. E. Griffiths, Mr. Samuel Ashmead, and Dr. Joseph Leidy. Dr. Griffiths made a collection of the species found about Cape May, while Mr. Ashmead’s specimens are mostly from Beesley’s Point. Dr. Leidy’s collections were perhaps the most important made since Say’s time, and embraced material gathered from the early fifties till 1890. This was, fortunately, usually studied and the results published, first as a list in his memoir entitled ‘‘Contributions toward a knowledge of the marine invertebrate fauna of the coasts of Rhode Island and New Jersey,” in 1855, and later by a few short abstracts, made mostly as verbal communications at the meetings of the Academy of Natural Sciences of Philadelphia. All these articles appear in the publications of this institution. Professors A. E. Verrill, S. I. Smith and O. Harger, in their more or less combined accounts, in the “Catalogue of the marine THE CRUSTACEA OF NEW JERSEY. 37 invertebrate animals of the southern coast of New England and adjacent waters,” in the first volume of the Report of the United States Commissioner of Fish and Fisheries, give a list of the Crustacea studied, also including a number from New Jersey. This work is accompanied by good figures, which, in the case of the Crustacea are only at fault in that they are so few. Pro- fessor Harger published a detailed account of the Isopods, well illustrated, in a later volume of the same journal. This fur- nished, with the records scattered throughout, the first fairly representative account of the group as applied to New Jersey. The same may also be said as regards the earlier work, with respect to the other groups. In 1888 Professor Angelo Heilprin published a semi-popular work, entitled “Animal Life of Our Seashore,” intended to treat of the more conspicuous invertebrates along the southern coast of Long Island and the shores of New Jersey. But a few species of Crustacea are mentioned with reproduced figures, mostly from Smith and Harger. The work is unfortunate as an incomplete compilation, The remaining contributions to New Jersey carcinology are largely in the form of collections from Mr. Witmer Stone, Mr. J. E. Ives, Dr. Benjamin Sharp, Dr. Henry C. Chapman, Dr. Henry A. Pilsbry, Mr. W. J. Fox, Mr. H. L. Viereck, Mr. J. A. G. Rehn, Mr. Bayard Long, the writer, and others. The most important was made by Mr. Stone, together with Prof. Amos Brown and Mr. Stewardson Brown, in the late eighties, at Point Pleasant. Mr. Ives secured material at Holly Beach, Dr. Sharp at Townsend’s Inlet, Mr. Fox at Sea Isle City, Mr. Viereck at Cape May, Mr. Rehn at Atlantic City and Mr. Long at Spray Beach on Long Beach Island. Finally, my own material was secured at Cape May, in various parts of Cape May county, Anglesea, Stone Harbor, Sea Isle City, Corson’s Inlet, Ocean City, Atlantic City, Great Bay, Seaside Park, Manasquan, and many other places within the State. 38 REPORT OF NEW JERSEY STATE MUSEUM. Descriptive Account of the Species and their Higher Groups. RELATIONSHIPS. The great group or phylum containing the Arthropoda em- braces the greater number of known forms of life. They are characterized chiefly by the metameric segmentation, more or less perfected bilateral symmetry—the mouth and anus being placed at opposite ends of the elongated body—and a nervous system formed of a brain dorsally and a double ventral chain of ganglia. Each typical segment of the body carries a pair of appendages, which are divided into distinct limb-segments or podomeres, which are separated from one another by movable joints and acted upon by special muscles. These features will serve to distinguish them from the segmented worms. Arthro- pods have further characters in the almost universal absence of cilia, the muscles are nearly always of the striped form, their sperms mostly non-motile, and the body-cavity is largely repre- sented by spaces (the blood-sinuses), in free communication with the circulatory system. The classes of this phylum usually ad- mitted are five, as the Crustacea, Onychophora, Myriapoda,. Insecta and Arachnida. ‘The Crustacea include the crabs, lob- sters, shrimps, wood-lice, barnacles, water-fleas, etc. The Ony-- chophora are represented by only the curious Peripatus, cater- pillar-like in form. The Myriapoda embrace the centipedes and millipedes. ‘The Insecta includeall true or six-legged arthropods, such as cockroaches, locusts, flies, beetles, moths, butterflies, bees. etc. The Arachnida include the spiders, scorpions, mites, etc. Class CRUSTACEA. The Crustaceans. Body formed of segments, usually very distinct or well de- fined, motile, of considerable hardness, and without so-called internal skeleton. Five anterior segments joined or fused with THE CRUSTACEA OF NEW JERSEY. 39 prostomium to form head, while others mostly forming two sec- tions, as thorax and abdomen. Thoracic segments may be fused in greater or less number to form a cephalothorax. Head may have median eye, this often disappearing in adult life, and pair of compound eyes, both belonging to prostomial region. In case of latter jointed and elevated eye-stalks frequently developed. Head with appendages usually in five pairs. First, or anten- nules usually considered as of first metamere, more likely pros- tomial. Second, or antennz, are postoral or metameric ap- pendages moved forwards to preoral position. Third, are mandibles or crushing-jaws. Fourth are first maxille. Fifth are second maxilla. Thoracic and abdominal appendages of variable modification, as jaws, legs, fins or accessory reproduc- tive organs. Except antennules, appendages typically biramous, formed of a stem or protopodite which bears two branches, as endopodite and exopodite. External covering of body a chitinous cuticle, becoming thick and somewhat calcified in places where no movement is necessary, forms series of hard parts of sclerites, separated by flexible chitin, so that whole chitinous cuticle thus forms exoskeleton. ‘Typically one sclerite to each metamere be- hind head and to each podomere in appendages, but concrescence of sclerites often obtains. Exoskeleton produced into sete, which are hollow processes of cuticle containing prolongations of underlying epidermis. Respiration either by general surface of body or by gills, which are hollow offshoots of thoracic wall or of thoracic or abdominal limbs. Stemodzum and proctodeum form considerable portion of enteric canal, lined with chitin, and mesenteron gives rise to digestive glands. Body-cavity divided into compartments, most of which contain blocd and are por- tions of vascular system, though true ccoelome may be represented by compartments of body-cavity not containing blood and by cavities of reproductive organs. A’ vascular system formed of contractile heart, as muscular dilatation of dorsal vessel and communicating by valvular ostia with an enclosing pericardial sinus. Blood taken from heart to various organs by arteries, returned to pericardial sinus by sinuses and veins, and respira- tory organs interposed in returning current. Renal organs pecu- 40 REPORT OF NEW JERSEY STATE MUSEUM. liarly modified nephridia, formed either like shell-glands opening on second maxilla or antennary (green) glands opening on an- tenna. Nervous system consists of brain united by cesophageal connectives with ventral nerve-cord, formed of double chain of ganglia joined together by commisures and connectives. First three pairs of embryonic ganglia commonly unite to form brain, which therefore syn-cerebrum. Sexes separate or united, sexual dimorphism common, and parthenogenesis frequent. Sperms usually non-motile, and eggs usually centrolecithal, sometimes telolecithal, or almost alecithal. Muscles striped, and no cilia. Segmentation of oOsperm usually superficial, but may be com- plete or discoid. Embryo passes through nauplius stage, which may be free-swimming larva or may be passed through before hatching, and characterized by three pairs of appendages, which form into antennules, antennz and mandibles of adult. The crustacea are thus seen to form a very great assemblage of animals as here understood. The group Xiphosura, or king crabs as they are commonly known, are now usually admitted with the Arachnida. ‘The crustacea agree with them, however, in that both typically breathe in water by means of gills joined to the appendages. The absence of antennz will serve to dis- tinguish the king crabs at once, and in this character they share alike with all the other Arachnida. The ethology has been summed up very comprehensively by Messrs. Parker and Haswell, from which the following is largely extracted. Crustacea are remarkable for their very perfect adaptation to the most various conditions in life, occuring in the fresh waters, in the sea, in brine pools, in subterranean caves and on land, throughout the globe. Many of those living in the sea are littoral, others pelagic, and some abyssal, descending in the depths of the sea over three thousand fathoms. Certain copepods (as Pontellina) are said to be almost aérial, leaping out of the water or apparently flying in similar fashion to the flying fishes or exoccetids. Solitary forms are found in such types as the lobsters, crawfishes, etc., while the contrary is seen in the im- mense shoals of shrimps. Most crustacea prey on living animals or devour carrion. In the case of fixed forms, like the barnacles, THE CRUSTACEA OF NEW JERSEY. 41 minute particles form the food in similar fashion to that of many of the lower animals. Members of more than one order are parasites, remarkable alike for their wide and often bizarre deviation from the typical structure of the class, and their adaptation to their peculiar mode of life. In size they present almost every gradation from microscopic water-fleas to crabs two feet across the carapace, or four feet from tip to tip of legs. Geographically the distribution of all the chief groups are cos- mopolitan, and only among the families, genera and species are points of interest from this view to be found. Fossils are known from very early time, though the oldest are usually referred to the Phyllocarida, ranging from the Cambrian to the ‘Trias. Shells of Ostracoda are also known from the Cambrian upwards, and those of Cirripedia from the Silurian. Arthrostraca are known from palzozoic times, but are rare as fossils. The earliest Macruran is a shrimp-like form from the Devonian, while the highly differentiated Birachyura are not known with absolute certainty until Cretaceous time. The recapitulation theory was first worked out in detail in the crustacea. Embryology shows that all crustacea may be traced back in individual development to the nauplius, upon which fol- lows some kind of zoza-stage, many entomostraca progressing no further. But in malacostraca the zoza is followed by the myysis-stage, which is permanent in schizopods and transient in decapods. Though a tempting hypothesis it is only necessary to recall that all such free larve are subject to the action of the struggle for existence, and may likely have been modified in accordance with their own special needs and without reference either to their ancestors or to the adult species into which they finally change. Many crustacea present instances of protective and aggressive characters, as modifications in form, color, etc., which serve to conceal them from their enemies or from their prey. Probably the most striking example is that of certain crabs (Paramithrax ) which deliberately plant sea-weeds, sponges, alcyonarians, zo- Ophytes, etc., all over the carapace, and are thus perfectly con- cealed except when in motion. Another crab (Dromuia) carries 42 REPORT OF NEW JERSEY STATE MUSEUM. a relatively immense ascidian or sea-squirt on its back, and in another species of the same genus the hinder legs are used to hold umbrella-wise over the back a single valve of a bivalve shell. Several instances of commensalism occur. Certain sea-anem- ones (Adamsia) are always found on a univalve shell, such as that of a whelk, and the latter inhabited by a hermit-crab. The sea-anemone is carried about by the crab and in this way secures a more varied and abundant food-supply than would fall to its lot if it remained in one place. On the other hand the crab is protected from the attack of predaceous fishes by retreating into its shell and leaving exposed the sea-anemone, which, owing to its toughness, and to the pain caused by its poisonous stinging- capsules, is usually avoided as an article of food. Other inter- esting occurrences are the little oyster-crabs (Pinnotheres) liv- ing in the mantle-cavities of oysters and mussels. Other deca- pods are found in the intestines of sea-urchins and holothurians, and one genus of crab lives in the cavity in a coral, the aperture being only just sufficient to allow of a due supply of food and water. The crustacea apparently exhibit certain characters with the object of attracting the opposite sex. The immniensely enlarged and highly colored chelipeds of some male crabs (Uca) are said to be used for attracting the female as well as for fighting. The sound-producing organs of some decapods have probably also a sexual significance. The rock lobster (Palinurus) has a soft, chitinous pad on the antenna, which it rubs against a projecting keel on the sternal region of the head, producing a peculiar creak- ing sound, and another macruran (Alpheus) makes noises by clapping together the fixed and movable fingers of its large chelipeds. The fact that these sounds can be produced at the will of the animals seems to show that they undoubtedly possess a sense of hearing, and that the auditory sac is not merely an organ of the sense of direction.

Crustacea living mostly in fresh-water pools or in brine lakes and ponds (Artemia), often where the water completely evapor- ates insummer. The eggs, after being fertilized and borne about for a time under the shell or in egg-sacs, finally are allowed to drop to the bottom of the pool. ‘There they lie after the water disappears or evaporates, remaining in the dry mud in drought or hot weather until the rains of autumn refill the ponds, when the young hatch out and begin the life cycle anew.

My description, as given above, is based on six examples obtained in March, 1891, by Mr. J. S. Witmer, Jr., at Paradise, in Lancaster county, Pennsylvania. There are but few places in New Jersey where it has been ob- served and recorded. The first was at Woodbury, and subse- quently near Trenton, which latter will be mentioned below. Outside New Jersey it has several times been seen in the Dela- ware river valley in Pennsylvania. Mr. T’. D. Keim found it in ditches above Bristol, in Bucks county, on April 12th, 1908, when it was fairly abundant. Several years previously Dr. J. DeB. Abbott found it in pools in woodland a mile or so still north of this place, where it was very comimon during March. I also found it in this region March 25th, 1913. Mr. F. M. Meyers found it very abundant in “dry-land pond” near Bethle- hem, in Northampton county. He sent me a specimen in March, 1913. I have also examined a number of examples from Long Island, received from Gissler, though now very poorly pre- served. Mr. W. T. Davis forwarded some examples he ob- tained at Staten Island, N. Y., in March and April of 1897. Dr. Charles C. Abbott gives the following interesting account of this species from near Trenton. ‘‘Animal life, in April, must not be ignored. Many creatures that have been comparatively inactive during the winter are now gradually assuming their summer restlessness. Among the countless hundreds of objects. worthy of the rambler’s attention, perhaps none are so beautiful and full of interest as the fairy shrimps that throng the dark waters of an upland sink-hole. This hollow in the field has a foot or more of water in it from November to June, and during the past winter it was frozen to the bottom until the Ist of April. A hard time, therefore, thought I, have these fairy THE, CRUSTACEA OF NEW JERSEY. 49 shrimps had, with not a drop of water to move in; but they are not to be judged by the delicacy of their anatomy. ‘There was a soft spot in the mud, somewhere, and when, later in the month, I waded between cakes of ice and looked long into the depths of this upland pool, finally I found the fairies in abundance, a few well grown, but mostly mere babies. They were earlier in 84. On the 22d of the month I gathered a great many, and all fully grown. ‘To describe them) is impracticable. They are lilliputian lobsters, pearly white, picked with crimson; and with eleven pairs of feathery legs that move with the perfection of erace. They swim upon their backs, and the movement of these legs or paddles is the very poetry of motion. While the water remains cool, they will dart, float and ramble among the dead twigs and leaves in the bottom of the pool, but disappear promptly, after a few hot days, or more gradually, as the waters soak away, if the weather is cool. Dr. Packard says of them: ‘At Seekonk, Mass., they occurred abundantly May 2, in a large pond which completely dried up in summer; * * * when I visited the pond * * * May 13, none were to be found. It seems from this quite evident that the animal probably dies off at the approach of warm weather and does not reappear until after cool weather sets in late in the autumn, being represented in the summer by the eggs alone; and thus the appearance of this Phyllopod is apparently determined mainly by the tempera- ture.’ Bearing this in mind, I took several lumps of the dried mud, last summer, and placed them in ice-water, hoping to have the egg's, if there were any, hatch, and so puzzle the doctor with midsummer specimens, but the plan did not work. Either I got no eggs with the mud, or the water was too cold; at any rate, my plan was a failure, and, as it was intended to be a joke, de- served no better fate. Returning to pure science, I waded the waters of that upland pond faithfully until it froze. I could find no specimen. Ejven in March of ’84 there were none to be seen; and this year, ’85, they were apparently but a few days old, as late as April 1. In an aquarium they are very beautiful, but must be kept’by themselves. A dozen were placed in a small tank containing mud-minnows and sunfish. The latter ate the 4 MU so REPORT OF NEW JERSEY STATE MUSEUM. beautiful fairies as though they were an ordinary article of their diet; but the mud-minnows would not touch them. Later, I placed innumerable minute leeches in the same tank, and these the minnows greedily devoured, but the sunfish ignored them completely.’’! Genus INO Schrank.

Seal in ditches near Woodbury, where it was found abund- ant. _It was subsequently secured there, as late as March 27th, in company with Eubranchipus vernalis, as reported by Parkard. My only acquaintance with it was at Chincoteague, in Acco- mac County, Virginia. On May 4th, 1912, I secured the ex- ample described above from a little pond of fresh-water. This pond was separated from a brackish-water inlet and glade by only several feet of dry soil. Several fresh-water mollusks were also found associated, besides Gammarus fasciatus, Asellus com- munis, water-striders, water-boatmen, very many larval dragon- flies and a few Rana pipiens. The occurrence of this species in Virginia is quite interesting, not only on account of the physical location, but as indicating the most southern point at which it is so far known to occur. According to Packard, the head of the female is simple and without frontal appendages. Her egg-sac is small, short and contains about a dozen very large eggs. He also gives her size as slightly exceeding the male.

Packard is rather ambiguous in his quotation from Gissler, and from the paragraphs quoted it is not clear that the latter ever secured Streptocephalus sealu in Long Isiand. Sub-Order CLADOCERA. The Water Fleas. Feet more or less leaf-like. Body enclosed in lamina of thin chitine more or less, or at least latter forming sac for protection of eggs. ‘This so-called shell springs as a fold from maxillary segment and conspicuously and variously formed. Young with single median eye, and this sometimes lost in later life, or some- times remaining as the only visual organ. Outer covering of body mostly changed by frequent moults. Besides the single group or super-family embraced in this work, members of the other group, or Gymnomera, will likely be added with future studies. Super-Family CALYPTOMERA. Body enclosed in a bivalve shell. Mandibles truncated below. Maxille distinct, spiny. Thoracic ganglia discrete. Key to the tribes. a.

Key to the families. a. Rami of both antenne three-jointed; intestine convolute, with abdominal but no-anterior ceca. LYNCEIDA aa. Rami of antenne three and four-jointed; five pairs of feet, last with curved appendage guarding branchial sac; antennules of female short, one-jointed. DAPHNIDA Family LYNCEID. Head covered with an arched shield, this often passing without an indentation into the shell of body. Head covering generally extending forward and downward to form more or less of sharp angle in front, or simply rounded. In either case it arches over . more fleshy lower side of head, from which hang two short antennules and labrum, while strong two-branched antenne spring from well up under its posterior expansion. Rounded sides of shield, which protect insertion of antennz known as fornices. Above insertion of antennz a dark fleck lying near or on lower angle of brain, which is the larval or nauplius eye. This black spot often large as eye itself, even larger, and sometimes the only visual organ. Antennules small, with several sensory filaments, and a lateral flagellum at end. Antennules in male differing little from those of female. Labrum with triangular or semicircular process, and usually larger than terminal portion. Mandibles similar to, though usually shorter, than in Daphnide. Maxillz often conspicuous, and first pair of feet serving by slight alteration at base same purpose. Rarely an indication of sixth pair of feet, and antenne with both rami three-jointed. End of body, or post-abdomen, usually enlarged, anal opening near its base, and armature usually considerable. Genera numerous, comprising very small species, and but few exceed one millimeter in length. The shell is various in form, often beautifully sculptured. A limited number of eggs is pro- duced at one time and the winter eggs are very often laid in the brood-cavity with no preparation of the shell previously, in which case the ephippium is said to be absent. Negatively, the shell may be considerably modified, generally with a deposit of THE CRUSTACEA OF NEW JERSEY. 57 dark pigment in its upper part. The males are very rare and have been seen but seldom.

Description.—Shell large, mostly of very slight ovoid contour, lower edge but little curved or scarcely so much as back, and ends in a small point or spine behind. Posterior and lower edge of shell sometimes with a series of fine hairs. Most of entire sur- face of shell with fine or more or less obsolete transverse wavy strie. Back depressed, with indention at root of neck. Head rather triangular, large, rounded before and above eye. Eye large, conspicuous, high. Beak rounded, obtuse. Antennules rather short.

Sometimes second line seen to emerge just above end of fornices and pass over eye in wide curve. Post- abdomen truncate behind, with long terminal simple claw, four others graduated down follow close behind. Color in life largely transparent, though with rather brownish or russet tints. Length 3 mm. Remarks.—Vhe above description is from examples I obtained in a small rain-pool of fresh-water on the brackish tidal marsh of Dennis Creek, at South Dennis, in Cape May County, April 5th, 1912. No other animal life was discovered associated, nor were any of Eurycercus in the similar but larger numerous pools all about. The pool in question was merely a depression in an unfrequented path on the meadow, and in size was scarcely larger than a good-sized wash basin. In a few hours it had dried up entirely, all of Eurycercus having disappeared or perished: During life these small animals appeared like small seeds moving about the bottom from place to place, swimming more or less direct. ‘They were easily located with the naked eye. Diligent search in many pools about the flooded adjacent marshy region failed to reveal any other examples. The species is said to range all over Europe and the eastern United States, though it has never before been recorded from New Jersey. Turner reports it from Kent County, in Delaware. Sub-Family LYNCEINA. Intestine coiled. Vent near end of post-abdomen. Opening of vas deferens nearly terminal. No anterior ceca, but usually a single anal diverticle of intestine.

These animals are minute round creatures appearing like mov- ing pin-heads as they wander about with a wavering or rolling motion. They usually live on vegetation, or slime, which occurs in the bottoms of small, quiet pools. In bright sunlight, which they seem to prefer, they sometimes occur in immense numbers near the surface. ‘The males have been found but rarely.

Remarks.—I first discovered this species in New Jersey in pools of fresh water about South Dennis, in Cape May County, on 60 REPORT OF NEW JERSEY STATE MUSEUM. April 5th, 1912. It was very abundant, frequently occurring with other small entomostracans. I next found it in May of Ig12 ina small tributary of the Delaware below Florence, where it was quite abundant with species of Scapholeberis, and in July and August it was abundant about Trenton. It likely occurs throughout the State. Chydorus bicornutus Doolittle. PLATE 8. Chydorus bicornutus Doolittle, Proc. Biol. Soc. Wash., XXII, 1909, p. 154.

Grover Mill Pond, Princeton, New Jersey. _ Female.—Body rounded in lateral view, ventral margin sharply ventricose. Body as seen from above broadly oval, front same, and sides concave dorsally. From each valve body a great horizontal horn stands out, curving slightly posteriorly, often half width of body proper. From this horn two high ridges run forward, and also two over back from horn to horn. An area on back immediately anterior to interspinal ridges bounded laterally by two other ridges. Near front limit of area, these ridges, after giving off on each side high lateral branch, sharply con- verge and unite in median line, forming a short crest where head and body meet, then diverging on head they bound or enclose large area in front and continue down to tip of rostrum. On lower half of each valve four more high ridges, taking their origin near each other at upper end of ascending anterior mar- gin of valve, and running more or less parallel to margin, but second and fourth from margin not running whole length of valve. First and third, however, unite at dorso-posterior angle, run forward on back to interspinal ridges, flaring outward, thus united ridges of opposite sides bound a dorsal area posterior to interspinal ridges. Between parallel ridges, except those arising from lateral horns, there pass partitions forming deep large rectangular cells. Within areas as described similar cells of various sizes and shapes. Laterally above marginal ridges othter THE CRUSTACEA OF NEW JERSEY. 61 deep hexagonal cells of various sizes. Eyes iarge, with few facets, ocellus adjacent.

Maxille with two heavily ciliated teeth. Feet, five. Post-abdomen broad, rounded distally, with twelve spines on dorsal or anal border. Claw strong, basal teeth two, proximal smaller. Length about 0.55 mm. Male —Unknown. (Doolittle. ) Remarks.—This species was originally found in lakes in Maine, and is recorded from Princeton, in 1911, by its describer. In color it is said to be yellowish. The eggs are two. The New Jersey examples are found to belong to the short-horned type. Family DAPHNID. Rami of antennz three and four-jointed.

This genus is the most conspicuous, and the one frequently seen. Young hatched with a pendant appendage attached to upper posterior angle of shell, and this soon becoming the rigid spine characteristic of the younger stages and males of the genus. Females almost immediately after birth begin produc- tion of eggs by an asexual process. Groups of epithelial cells containing four each are formed and one of the cells of each group develops at the expense of the others, forming the egg. Many such eggs are laid simultaneously and deposited in the cav- ity between the shell and the dorsal part of the animal. Daphne pulex (Linnzus). PLATE 9. Daphma. Red Daphnia.

THE CRUSTACEA OF NEW JERSEY. 63 Remarks.—This little crustacean is very valuable as food for many of our fresh-water fishes. It is also in demand by breeders of aquarium fishes, as forming food for the fry, especially those of the gold fish with its ornamental varieties. It appears to be common only periodically, and especially during the spring of the year or in the month of May. At this time it may be seen in great abundance in the ditches about Camden and Philadelphia, the myriads of individuals often imparting to the water a bloody appearance. The color varies from perfectly transparent to the deepest dull red, though the former condition is the most usual in which individuals are found most of the year. It is widely distributed, occurring in many parts of the United States and Europe. Genus SCAPHOLEBERIS Schoedler. Scapholeberis Schceedler, Die Branchipod, Berlin, 1858, p. 23. Type Daphne mucronata Miiller. (Not consulted.) Body robust, continuation of fornices extending toward apex of incurved beak, which usually lies within valves of shell. Lower posterior angle of shell angled or spined. Lower anterior angle of shell with a prominence and a basin-shaped area encloses base of antenne, latter partly lying on shell and part on head. This area more strongly lined or reticulated than rest of shell. Lower margin straight and ends usually in a long scythe-shaped spine which directs backward. Shell usually indistinctly reticulated or unmarked, and usually deeply colored. Post-abdomen similar to that of Ceriodaphnia or Simos, with anal spines few and older specimens having more than young, and place where additional spines are to appear marked by prominences. Eye moderate in size, pigment fleck rather small and short antennules hidden by beak. Antennz of small size and generally dark colored. Ephippium containing but one egg.

Description.—Body of rather irregular semi-circular contour, that of back convex and of ventral region nearly straight, ending behind in short spine at each posterior angle of shell. These spines quite short and barely equal head or one-fourth length of shell. Lower straight edge of shell with a series of moderate fine spines. Head rather large, round in front of large eye. A short rounded beak on lower surface of head. Antennules short, behind and below beak. Fornices very short, rounded, connected by a line with beak by a sudden downward deflection, this off- setting area forming part of basin of antennz. Second line springs from just above end of fornices and passes over eye by broad curve. Post-abdomen truncate, has beside terminal claws four or more spines rapidly decreasing in size. Claws minutely spined. Color usually dark brownish. Length 0.6 to 0.8 mm. Remarks.—I first met with this species in pools about South Dennis on April 5th, 1912, when a few were found in company with Eurycercus and Chydorus. In May it was found in a little tributary of the Delaware just below Florence, also associated with Chydorus. On July 4th, 1912, it was found fairly common in a tributary of Crosswicks creek near Trenton, where it was associated with Scapholeberis armata, Cyclops serrulatus and other species of Cyclops. Likely it is common in many places throughout the State. It is widely distributed in Europe and North America. THE CRUSTACEA OF NEW JERSEY. 65 Scapholeberis armata Herrick. PLATE II.

Description——Body rather oblong, back scarcely more convex in profile than ventral surface or edge, and latter ending behind in long spine, often equaling entire lower margin of shell in length. Lower edge of shell with a series of fine hairs, each moderately long. Head rather large, rounded in front. On lower surface of head a short rounded beak. Eve large. Anten- nules short, below beak. Fornix rather broad, somewhat square, basin of antennze small, upper lines meeting behind eye. Post- abdomen truncate, with four terminal claws. Color dark brown- ish. Length 0.8 mm. Remarks.—First found with the preceding in the tributary of the Delaware below Florence, in May of 1912. It was very abundant in a tributary of Crosswicks creek near Trenton on July 4th, 1912. About Philadelphia, in Pennsylvania, I have also found it at Holmesburg, in pools, and in a pond near Elkins Park. It is evidently a species of wide distribution in the United States. Although Herrick refers in the above-quoted work to this species in the American Naturalist for 1883, as Scapholeberis mucronata var. armata, I cannot find it in the volume before me.

Antenne long, biramose, with unequal branches. Mandibles truncate at end. Maxille armed with large spines. Form of body usually elongate, and abdomen often extends beyond edge of shell behind. Male openings usually in end of long append- ages which depend from base of post-abdomen. Several genera in America, though only one known from New Jersey. These animals are usually to be found in the clear and colder waters of large lakes. ‘‘hey produce winter eggs, laid in October, which differ from the summer eggs, which hatch in the brood cavity, by a brown color and fatty spheres being pres- ent. These eggs are produced in large numbers, in distinction to most other Cladocera, in which the winter eggs are very few. The eggs fall to the bottom and there develop at the proper time. Some forms occur abundantly in areas of plant growth. As the size and reproductive energies are dependent on environ- ment, but little success may be expected if their preservation in aquaria is attempted. As some forms are nocturnal they should be sought at the surface of the water on quiet evenings. Genus SIDA Milne-Edwards. Sida (Straus) Milne-Edwards, Hist. Nat. Crust., III, 1840, p. 385.

Feet in six pairs, each of three articulations, and with several strong sete. ‘Transparent. Length 3 mm. Remarks.—Known to me only from several examples I secured in July of 1912 ina tributary of Crosswicks Creek near Trenton, in Mercer County. The species was not common and but few were found among the multitudes of Cyclops, Scapholeberts and other minute crustaceans gathered. I was, however, enabled to make the above notes and thus include the species in our list. According to Baird “the motion of Sida through the water is a sort of rapid running movement. They are generally inactive, and adhere in a peculiar manner by the back of their head to the side of the vessel in which they are contained, remaining there for hours. They adhere most probably in the same way to the weeds in the water where they are found, as it is by skimming the stems of the weeds that they are detached and 68 REPORT:OF NEW JERSEY: STATE MUSEUM. caught. They do not appear to be numerous in the localities in which I have found them, and indeed are of rage occurrence.” ? This species is widely distributed in both Europe and North America. Order OSTRACODA. Body enclosed in a bivalve shell. Body always with seven pairs of articulated appendages. Of these first five are append- ages to head, though in different groups one or all of last three pairs may be mlodified for locomotion. Last two pairs belong to the body and usually known as feet. Sometimes (Cypris) last pair of feet not used for locomotion. Usually abdomen ends in a pair of appendages which resemble legs. These little crustaceans so closely resemble certain molluca, like Spherium, that they are frequently mistaken for them by the novice. The animal however is quite crustacean in struc- ture, though primitive. As a rule they are poor swimmers, though some like Cypria, Cypridopsis and Cyclocypris swim quite well. Others move along the stems of plants, burrow in the sand or mud, or creep along the bottom, not swimming at all. The ostracoda usually occur in shallow waters, as ponds, pools, marshes, etc., and when occurring in lakes or rivers are usually to be found near or at the bottom, seldom venturing to the surface of the deeper waters. In our region the spring and fall are the best seasons for collecting. Tribe PoDocoPaA. Second antennz simple, subpediform, geniculate, clawed at apex, not very unlike upper antenne. Both pairs of antenne bear long sete and adapted for swimming, or shortly setose and not used for swimming. Mandibles distinct, mostly strongly toothed at lower extremity, with palp of moderate size, and bearing more or less developed branchial appendage. First pair of maxillz bearing large branchial plate. 1 Nat. Hist. Brit. Entomostr., 1850, p. 109. THE CRUSTACEA OF NEW JERSEY. 69 These characters, chiefly indicated by the simple second an- tennee, clearly distinguish the present tribe from the others. The Podocopa are mostly fresh-water, while the other tribes are marine. ‘These latter show the second antennze biramous, one immobile branch rudimentary and the other flexibly elongate with long natatory setze as the Myodocopa, both movable nata- tory branches well developed in the Cladocopa, and both branches flattened as in the Platycopa.

It does not appear to have ever been recorded from New Jersey before, though likely is to be found everywhere during proper seasons. Several times in the spring I have found thousands above Bristol, in Pennsylvania, in temporary pools, and as some of them were stained somewhat dark, owing to the infusion of old leaves, suspect that possibly De Kay’s Cypris hispida may have been colored from a similar cause? ‘This species was also found in examination of the stomach contents of young sturgeons (Aci- penser brevirostrum) secured in the fall of 1911 at Torresdale, Pennsylvania. Sharpe says of it: ““This species is ubiquitous, and I have yet to know of a pond or stream in which it has not made its home. It is seemingly always present in aquaria, and appears to play the role of scavenger, thriving in situations to which other Ostracoda seem to be totally unadapted. Viewed with a low power these creatures present a very pretty appearance as they rapidly swim about, the banded shell at once attracting attention.” I have allowed De Kay’s Cypris hispida to fall provisionally with this species, as it was likely a discolored specimen. De Kay’s description is as follows: “Valves when viewed together, re- semble a minute Modiola. Epidermis uniform jet-black, and covered with numerous whitish rigid hairs. Length, .og to .1 mm.” De Kay appears to never have examined living examples. Possibly the jet-black coloration may be due to preservation, or the condition of the water in which it was found. No writer since De Kay’s time appears to have met with it. In any case De Kay’s specific name cannot be used as it is preoccupied for a species of Candona. 74 REPORT OF NEW JERSEY STATE MUSEUM.

Five thoracic segments each THE CRUSTACEA OF NEW JERSEY. SI with pair of swimming-feet, consisting typically of two-jointed base and two like three-jointed rami. The symmetry frequently broken by retardation of development of inner ramus, while fifth pair of feet may become rudimentary and in various ways sub- serve organs of sex. Five abdominal segments nearly devoid of appendages and continued posteriorly by two caudal stylets which bear strong setze constituting, in many forms, a tail-fin or spring. These minute and mostly predaceous animals are not only use- ful as scavengers but supply the food of most fish fry, as well as of other animals. They are distributed in both salt and fresh water, and while the latter forms are perhaps few in species they make up in the numerous individuals. Though the scheme of divisions into suborders as adopted by Giesbrecht is used here, very likely the more recent views of G. O. Sars, who admits seven, as the Lernzoida, Caligoida, Mon- strilloida, Notodelphyoida, Cyclopoida, Harpacticoida and Calan- . oida, will be found necessary.

Feet various, developed for walking or prehension, partly with branchiz, and modified for swimming. Body mostly enclosed, usually almost entirely, in a buckler, consisting generally of one piece, though occasionally of two. Besides the families represented in New Jersey limits, so far as known at present, a number of others from the Middle At- lantic and adjacent faunas will doubtless be added with future researches. All but one of the New Jersey families treated below are parasitic, for the most part on fishes, etc. The following interesting remarks concerning these animals are from Dr. C. B.. - Wilson. The problems of parasitism and its attendant degeneration are among the most interesting in the whole realm of ecology, and nowhere can they be studied to any better advantage than among the parasitic copepods. We can find here every grade. of parasitism and can easily follow the resultant effects in the habits and morphology of the parasites themselves. There are forms like Argulus which not only move about all over the body of their host, but also change frequently from one species of fish to another, and can even leave their host at will and swim about freely, sometimes for several days, before ;returning. Retaining thus completely their powers of locomotion we should not expect, nor do we find in them, any degeneration, but rather such a modification of the various organs especially used in parasitism—e. g., organs for clinging to their host, for piercing after blood, etc., as will the better adapt them to their specific use. Then we find forms like Caligus which roam about freely over their host’s body but do not apparently leave it voluntarily, though they can swim well enough when compelled to do so. 1 Proc. U. S..Nat. Mus., KXV, 1003, pp. 641-622. THE CRUSTACEA OF NEW JERSEY. 83 Here also we should not expect any marked degeneration, but rather a more complete adaptation of the various organs. The first evidence of degeneration in this genus lies apparently in the inclination toward free swimming and not so much in the ability to perform it. In these two genera, Argulus and Caligus, the males and females differ but slightly, and in some species of Argulus they may even-be approximately of the same size. The fact that the Argulide do not carry their eggs about with them tends still farther to eliminate the sexual differences, while in the Caligide the presence or absence of the long egg pouches with the attendant modifications of structure constitute the chief sexual distinctions. Not so, however, in forms like Pandarus, for here both sexes usually fasten themselves in one place and remain there for a long time. They are also so dissimilar in habits and structure that the males have been hitherto placed in an entirely separate genus (Nogagus), and the two sexes have been proved to belong to the same species only by being repeatedly found in actual co- ition. As is usual in such cases, the female is the more de- generate and can only crawl about slowly; she is so heavy and clumsy that she cannot swim at all. Here then is evidence of structural degeneration, not very marked as yet, since fully developed swimming organs are re- tained though they cannot be used in the adult state. The male Pandarus, on the contrary, not only retains the loco- motor structures, but can use them, being able to swim about freely whenever occasion demands. Again there are forms like Philicthys in which both the male and female have become practically incapable of locomotion, but are still found free in the mucous canals and sinuses of fishes. In them the locomotor organs are markedly degenerate, having dwindled to mere stumps without joints or sete. And, finally, we have forms like Chondracanthus, Anchorella and Lernea, in which the female is absolutely incapable of motion, being fixed in one position for life, while the male has dwindled to a mere pigmy, adherent to some part of the female’s body. 84 REPORT OF NEW JERSEY STATE MUSEUM. The male can still move about somewhat, but the female has lost all trace of every appendage except those which serve to fasten her to her host. Key to the families. a.

Remarks.—I first discovered this interesting parasite attached to the gills of Pomolobus pseudoharengus taken in the Delaware River (at Tullytown, Pennsylvania) opposite or a littie below Florence, in Burlington County, on May 17th, 1912. At the same time I also found a few in the branchial cavities of Pomolobus estivalis. On May 28th, 1912, I again visited this locality and examined hundreds of individuals of both species of Pomolobus, and secured about ten more specimens. It is not a common parasite, and often dozens of the herring must be ex- amined before one is located. ‘They are easily seen, however, their white sac-like bodies strongly contrasting against the dark and red color of the gills.

Remarks.—I have seen this species in New Jersey menhaden (Brevoortia tyrannus), but have no examples from the State’s limits at present. It is, however, very common at times, and then almost every fish one meets with is infested with at least one parasite, often several or more. It is quite conspicuous, the distended posterior portion of the thorax usually being depressed parallel with the axis of its host and trailing along. The para- sites are often found protruding most anywhere from their host’s body, usually somewhere along the back, often from the dorsal fin, and sometimes they hang out from the region under the tongue, trailing along like a barbel. The head of the parasite is deeply imbedded, usually with its flexual cephalic tentacles wrapped about some portion of the skeleton of its host and thus well under the muscular tissue. The long anterior filamentous thorax moves freely within a well-drilled aperture through the fish's flesh so that usually only the distended portions and egg- strings are pendant. That sometimes these apertures are either distressing or serious to the host cannot be doubted, especially when they occur in numbers and the parasites are numerous. Then, according to the fishermen, fish will be found swimming about in a weakened condition and sometimes have dozens of their tormentors hanging from them. Such fish are usually easily secured, though too sickly to be valued. So deeply im- bedded are these creatures that it is only by careful operation in cutting into their host that they may be secured intact, and then the head is usually removed unimpaired only with difficulty. Even small or young fish are frequently parasitized. According to many fishermen, and most of them are entirely ignorant as to what the lernean really is, the infested fish are sometimes said to be ‘‘shedding their bones”’! THE CRUSTACEA OF NEW JERSEY. 89 Other material, and I have examples in great number from the region of Chincoteague in Accomac County, Virginia, were secured during May of 1912. Numbers of menhaden examined there were found to be greatly infested. 1 also have one of these parasites taken from a small menhaden, though the parasite itself is quite adult, from Fort Macon, in North Carolina, many years ago by Dr..H. C. Yarrow. On July 3d, 1912, I examined a menhaden (Brevooriia tyrannus) which had several examples of this lernean punctured through its back. The fish was caught in Great Bay in Ocean County.

Remarks——kKnown from our coast only on the record given by Leidy in 1890. His examples were taken during the same summer, hanging in great clusters from the root of the dorsal and other fins on the Mola mola, captured at Beach Haven. His specimens varied from 124 to 176 mm, in length, and the neck was buried in the flesh of their host from 32 to 76 mm. Many were also parasitized with the barnacle Conchoderma virgata and the hydroid Eucope parasitica. I have two examples, also taken from a Mola mola, and obtained by Captain John L. Howard. ‘hough labeled ‘Port Richmond, Philadelphia,” they were possibly secured from a host captured somewhere off the coast. One example shows a large barnacle, Conchoderma virgata, attached to the lower sur- face of the abdomen. De Kay’s Penella plumosa appears to be this species. It is described as having a body capable of great contraction and dilatation. The enlarged head has- numerous foramina at its end, and there is a rudiment of a third elongated process on the nape. The caudal extremity has a series of processes on each side, eighteen to twenty in number, and appear bulbous under a | lens. In color all the free portion of the animal is dark red or purple. Its length is two to three inches. De Kay gives two hosts, which he apparently credits to his work on the fishes of New York, but neither occur there under the name Rhombus ferrugineus and Diodon plumosus. The former of these is likely his Platessa ferruginea (== Limanda ferruginea) and the latter his Diodon fuliginosus (== Chilomycterus schepf). Pennella sagitta (Linnzus). PLATE 23.

He further says that various parasitic animals, such as Pennella sagitta and Tristopus coccineum, are found frequently adhering to its body. It seems hardly likely De Kay could have confused this species with Pennella filosa, and for this reason his record is allowed to remain distinct provisionally. Genus LERNEOCEROPSIS new genus.

Color with head and anterior constricted thoracic region very pale or pellucid. Distended thoracic region deep maroon-red, and long egg-strings pale. Total length about 83 mm. Male——Unknown. | Remarks.—I first discovered this species on an alewife, Pomo- lobus pseudoharengus obtained in the open Delaware River and brought into the fishery of my friends, Messrs. R. and H. H. Burton, at Tullytown, in Bucks County, Pennsylvania. This specimen was captured on May 28th, 1912. About several hun- dred alewives were examined, but no more parasites were found in any of them, and they are not noticed by the fishermen. The method the latter employ of scaling the fish, by dumping them in a compartment and throwing sand over them, then several men in rubber boots tramping them about, of course, renders it impossible to examine fish for any of the protruding lerneans. I had the opportunity of examining the above example before it was so treated, and thus secured it intact. On July 1st, 1912, Mr. W. B. Davis and the writer secured several examples from the mummichog (Fundulus heterochtus macrolepidotus) along the shores of Great Bay in Ocean County. Two other hosts may be mentioned, as I secured it on the silversides (Menidia menidia notata) and the may fish (Fundulus majalis) at Assateague, in Virginia, on May 5th, 1912. It was not abundant, however, and only several specimens were obtained from several hundred: fishes. Type No. 2002, Academy of Natural Sciences of Philadelphia. Tullytown, Pennsylvania.

Third segment carries pair. of enlarged dorsal plates which cover front portion of genital segment. Latter large as, or larger, than carapace and with pair of dorsal plates which entirely cover this segment as well as abdomen. Abdomen one-jointed, with large anal laminz armed with spines instead of sete.

Rami of first three pairs with plumose setz in a few genera, fourth pair and all rami in other genera without them. Chalinius—Attached by two broad ribbon-like frontal fila- ments very short and parallel. Remarks.—The parasites of this sub-family are found largely on the Ocean sun-fishes (Molide), though they also sometimes occur on tunnies, porcupine-fishes, flat-fish, sharks, etc. The fol- lowing, compiled from Dr. C. B. Wilson, discusses their ecology: These parasites are more gregarious than the Pandarine and are found in bunches of fifteen to thirty or more, attached to the outside skin and gills of fish. The combined laceration of their 96 REPORT OF NEW JERSEY STATE MUSEUM. claws often produces a large pit or sore, in the bottom of which they cling tightly. Nothing of this sort is found among the Pandarine, as they do not collect in such numbers and cling partly, if not chiefly, by means of their adhesion pads. Hence when several of them get together, as often happens on a shark’s fin, there is very little laceration and no bunch or sore is formed. The abrupt transition and the consequent degenerate character of the male forms one of the chief characteristics of the group. The only locomotion possible to either sex is such as can be accom- plished by loosening one set of prehensile organs and obtaining a new hold by stretching the body, while still keeping a second set securely fastened. When once placed, with the second antennz buried in the flesh of the host, it is probable that the female does not subsequently change her position. The male is usually found attached to the female, the front margin of its carapace burrowed beneath the apron of her third swimming-legs, and its second antenne clasped around her fourth thorax segment. When he has once gained this position the male probably does not change it during life. The organs of prehension are similar to those in the Pandarine. ‘The chief hold is maintained by the second an- tenn, which are buried for their entire length in the skin and underlying flesh of their host. During life the body of the copepod frequently trails off in the water, with no attachment ~ to the host except these antennz, which gives it the appearance of being fastened by a frontal filament. Usually, however, the antenne are reénforced by the second maxillipeds and adhesion pads. The latter are similar to those in the Pandarine, but there are two of them behind each first antenna, while there is none on the base of the second pair. These parasites certainly never drop off into the boat or anywhere else, as claimed for the genera in the Pandarine. Both the antennze and maxillipeds are set so firmly in position that they cannot be loosened without break- ing them. Even after the death of the parasite it is usually necessary to cut around these appendages if one would remove the entire animal. When placed alive in the aquarium they are more helpless than the Pandarine, and both sexes can only lie in the place they are put, with an occasional weak and spasmodic THE CRUSTACEA OF NEW JERSEY. 97 movement of the swimming-legs. Hence they can be kept alive but a very short time. As they are gregarious and gather to- gether in colonies, whose combined lacerations form a deep pit extending through the skin and into the flesh of their host, they are kept alive after the skin of their host may have dried. Such a pit does not dry as quickly as other portions of the surface of the host’s body, and the parasites, being fastened in its very bottom, are not only protected from abrasion, but are also kept moist long after the fish’s skin has become dry and parched.

Frontal plates wide, fairly distinct, but still fused with carapace, and smooth, slightly curved frontal margin with small incision at center. Dorsal surface of carapace with well-defined grooves marking it off into similar areas as in Pandarine. Two longitudinal grooves strongly concave toward each other, like parenthesis marks, space between being nearly two-thirds of entire width. Lateral areas outside these grooves wider posteriorly, prolonged backward on either side in large lobe extending nearly to anterior margin of dorsal plates of fourth thorax segment. Each of these lateral areas divided by transverse groove which starts from deep sinus in lateral margin curving inward and backward to longitudinal groove.

Sinus between plates wide, well rounded at base, but farther back its sides approach until in actual contact. Combined plates of fourth and genital segments about same size as carapace and inversely same shape. As abdomen is hidden this produces a regular elliptical outline, broken across short diameter by waist between carapace and fourth segment. Joint between third and fourth segments seems to be only one really flexible, and anterior half of body frequently folded over ventrally against posterior half. Dorsal surface of genital segment covered by pair of plates similar to those on fourth segment and finely serrate around edges. Posterior sinus between these plates deeply cut, similar to that between fourth segment plates.

Abdomen length plus these plates about twice that of genital segment in front of abdomen. Lobes also set with fine teeth along their edges, and not rolled at margins, but flat. This space between them and genital segment, in which egg-strings are coiled, not as thick dorso-ventrally but wider than in Cecrops, thus accommo- dates about same length of egg-strings, twenty or thirty times body length. Strings about same diameter and eggs fully as numerous. First antennz three-jointed, joints diminishing regularly in diameter and in length from base outward, also very sparsely armed with sete. Second antenne large, three-jointed, projects well in front of carapace, terminal joint very powerful, strongly curved claw buried its entire length in flesh of host. Mouth-tube broadly conical, similar to that in Cecrops, mandibles projecting through opening at its tip, armed with square teeth on their inner margins only. Second manxillz in form of short conical knobs, apparently without joints, spines or rudimentary exopods, in size less than one-fourth length of mouth-tube. First maxil- lipeds two-jointed, both joints exceptionally stout and terminal slightly longer. ‘Terminal claw short, wide, heavily fringed with stout spines, and accessory claw in form of large spine. On ventral surface of joint opposite accessory claw a raised knob covered with small spines. Second maxillipeds swollen, basal joint much longer than terminal claw, on its inner surface two pairs of knobs, one near base of terminal claw and other near its own base. Claw when closed lies between two knobs of each pair. Legs all biramose, rami transformed into flattened laminze without plumose sete, and those of first two pairs two-jointed, while third and fourth pairs with but single joint. Color uni- form light yellow without any pigment markings. Claws and chitin ribs which strengthen carapace darkened to brownish hue. Total length 20 mm. THE CRUSTACEA OF NEW JERSEY. 105 Description of male-—Carapace similar to that of female, relatively little shorter and wider, grooving on dorsal surface indistinct. Eyes invisible in adult. No teeth along carapace margins laterally. Fourth segment plates nearly circular, their combined area well less than carapace, but covering more than half of genital segment plates, and posterior margins thickly set with teeth. They project forward at anterior corners in broad rounded shoulder on either side. Genital segment small, two- thirds size of carapace, orbicular in outline, strongly flattened dorso-ventrally, and dorsal plates fused along mid-line their anterior half, but separated for their posterior half, hind margins thickly set with teeth. Abdomen very small, weak, subquad- rangular, fastened to ventral surface of genital segment so that its hind margin coincides with that of latter. Anal laminz nar- row, oblong, nearly three times long as wide, each armed with four small sete. Dorsal surface of abdomen and anal laminz visible through posterior sinus between dorsal plates of genital segment. Appendages as in female, except second antennz and second maxillipeds larger, and more spines on swimming-legs. Fourth legs fully degenerate as in female, being enlarged into broad laminz with no signs of segmentation. Third legs like second pair, not enlarged, and each ramus two-jointed, joints about same size, but those of exopod nearly three times size of those of endopod. ‘Terminal joint of endopod in third legs armed with long single spine or claw, curved strongly outward. No plumose sete on swimming-legs. Color as in female. spermatophore receptacles deep purple, and ducts leading to them lighter purple. Length Ito to 15 mm. (C. B. Wilson. ) Remarks——Known from New Jersey limits by Leidy’s record of four females taken from a large sunfish (Mola mola) cap- tured at Beach Haven in 1890. ‘These, like his examples of Philorthragoriscus serratus (Kroyer), were found attached to ulcerated surfaces at the root of the caudal fin. The following notes are taken from Dr. Wilson’s exhatstive account: “It is found almost exclusively on the ocean sunfish (Mola mola), but lives on the outer surfaces of the body, often frequenting the anal fin or its adjacent regions. It occurs often 1066 REPORT OF NEW JERSEY STATE MUSEUM. in bunches of from ten to twenty individuals, so that even the thick skin of the host is quickly penetrated by the combined lacer- ation of the sharp claws and probosces of the parasites. Thus groups of parasites are found lying in the bottoms of depres- sions or pits, which have been eaten through the host’s skin and into the raw flesh below. The edges of these pits are often raised above the surrounding surface and calloused. Thus while themselves free from some dangers due to their fixed habit, their chitinous plates covering the dorsal surface often invite different vegetable and animal forms of the sea to a good anchorage. ‘Thus the back of an Orthagoriscicola may be found covered with aleze, infusoria, hydrozoa or barnacles. Sometimes,a huge Lepas may be found attached, and while not in sense a parasite, its heavy weight upon the copepod’s back is likely a sore burden.” Genus CECROPS Leach. Cerops Leach, Encyclop. Britan. Suppl. (Annulosa), 1816, p. 405. Type Cerops latreillii Leach, monotypic. Female.—Carapace oval, stout, strongly arched, deeply notched behind. Frontal plates fused with carapace. Cephalic and thoracic portions of lateral areas separated by transverse groove. Second thorax segment with large lateral lobes. Third segment with pair of small dorsal plates. Fourth segment with pair of larger plates. Genital segment small, carries pair of dorsal plates larger than carapace extending back beyond tips of anal lamine and forms dorsal half of bag in which eggs are carried.

Beach Haven, New Jersey (on Mola mola). Female-—Carapace oval, long as wide, with prominent frontal margin and deep triangular posterior sinus. Frontal plates almost entirely fused with carapace, separated by wide deep median sinus. On lateral edges just behind frontal plates a well-defined notch on either side in base of which first antenn:e are attached. Another notch a little posterior on lateral mar- gins formed by transverse groove separating cephalic from thoracic portion,of lateral areas. This groove far forward, thus cephalic portion in front of it small and triangular, while thoracic portion behind it nearly four times as large and trapezoidal. Second and third thorax segments fused, with single pair of lobes and single pair of dorsal plates. Broad lateral lobes ap- parently belong to second segment, reach well out beneath hind lobes of carapace. Small dorsal plates belong to third segment and overlap following segment a little. Fourth segment with pair of medium-sized plates which reach about to center of those on genital segment. Each small dorsal plate triangular with well-rounded corners. Genital segment with dorsal plates en- 108 REPORT OF NEW JERSEY STATE MUSEUM. larged nearly twice length of carapace, elliptical, about one- fourth longer than wide and sides very evenly curved. Genital segment covered by pair of dorsal plates with softened edges which project far beyond lateral and posterior edges of segment. These soft edges rolled over ventrally into large scrolls which completely cover sides and hind end of segment and lap quite a distance on to ventral surface, completely concealing abdomen, anal laminz and egg-strings in dorsal view. Posterior sinus between these plates sharply triangular, about one-fourth entire length of plates. Abdomen semi-elliptical, fully as large or larger than that portion of genital segment preceding. Its ven- tral surface produced into large lobe or lamina on either side, which extends outward laterally beneath turned-over edge of dorsal plates of genital segment. When ege-strings absent lateral and anterior edges of these lamine turned upward into scrolls, similar to those formed by dorsal plates of genital segment and inside of them. lLateral margin also caught inward in large fold on either side about one-fourth distance from its anterior end. This gives ventral aspect of abdomen pe- culiar T-shape, upright portion more than twice width of arms. When egg-strings extrude these folds and scrolls along lateral edges are straightened out and each lamina rests flatly upon ventral surface of coiled egg-strings, completely concealing them in ventral view. Scrolls along anterior edge never entirely straightened, but lamina on either side curls up over eggs at that point and holds them securely in place. Anal laminze small, orbicular, attached close to anus either side, and armed with short stout spines, without plumose sete. : First antenne two-jointed, basal joint much longer, and each joint armed with a few short spines. Second antennz large, powerful, principal organs of prehension, three-jointed, terminal joint strong sickle-shaped claw, which is buried in the host’s flesh. Terminal joint of first maxillipeds much shorter and more slender than basal, terminal claw nearly long as joint itself and only slightly curved, accessory claw much shorter, while both claws with serrate edges. Second maxillipeds stout, not swollen as in Pandarine, curved terminal claw nearly long as basal joint and THE CRUSTACEA OF NEW JERSEY. 109 shutting down between two large corrugated knobs on ventral surface of latter. Mouth-tube and maxillate peculiar, former conical with with swollen base, tapering rapidly to fairly sharp tip, from which ends of mandibles protrude. Latter straight, coarsely toothed along inner edges, teeth more or less rectangu- lar. Maxillaz enormous, club-shaped, each one large as whole mouth-tube and two-jointed, its hemispherical terminal joint cov- ered with small curved spines. On ventral surface of each max- illa, at base of terminal joint, a small knob represents rudiments of exopod. Swimming-legs biramose, rami two-jointed except of fourth pair, which modified into large laminz with indistinguish- able joints. Basal joints of exopods of first two pairs much larger than terminal joints and armed with stout spine at outer distal corners, one on legs exceptionally large. Segments of third legs all same size, while in fourth legs rudimentary endopod sev- eral times larger than exopod. In latter legs also large fold of skin caught up on ventral surface of each basal joint. When legs _are in place this fold fits into groove between abdomen and gen- ital segment, doubtless assisting materially in holding egg-masses in place. Coils of oviducts in front part of genital segment, estimated about twenty-five times length of body. Strings nar- row, and eggs thin, so that several thousand to a string. They are held securely between dorsal plates of genital segment and lateral lobes of abdomen until hatched, the nauplii ane at the hind end of the egg-bag. Color uniform yellowish-white, turning orange-brown in alco- hol in center of different carapace areas and dorsal surface of genital segment. Anterior ventral surface of abdomen and edges of dorsal plates of genital segment with a few spots of light brown. Egg-masses deep orange-brown. Total length 30 mm. Male.—Carapace as in female, with same grooving on dorsal surface. Cephalic and thoracic portions of lateral areas not dif- fering as much in size as in other sex, and posterior sinus rather deeper. Lateral lobes on second segment and dorsal plates on third and fourth segments correspond closely with female, last 110 REPORT OF NEW JERSEY STATE MUSEUM. covering whole of genital segment and most of abdomen... Gen- ital segment transversely elliptical, nearly twice wide as long, narrowed into neck where it joins fourth segment. Abdomen transversely elliptical, terminal, little more than half diameter, but much less than half length of genital segment. Anal laminz terminal, small, close to anus on either side and with rudimentary plumose setz. Appendages similar to those of female, with usual sex distinctions in larger size of second antenne, maxillz and second maxillipeds, and in an increase in number and length of plumose sete on swimming-legs. Fourth legs have large laminate basal joints and one-jointed rami, but no fold of skin in basal joints, and rami not as large and rudimentary as in female. Testes large, very apparent in well-preserved specimens. Color as in female, but rather lighter and more transparent, with- out pigment spots on ventral surface. Total length 17 mm. (C. B. Wilson.) Remarks.—This species is known from New Jersey waters by Leidy’s record. It was taken from the gills of Mola mola secured at Beach Haven in 1890. Leidy secured six mature fe- males about an inch in length, of which three had the male ap- pended. The males were about half the length of the females. He also secured three other young females. | So far as known the Mola seems to be the only host on which this species has been found. Sub-Family PANDARIN 2. First thorax segment only fused with head, others free. Sexes quite dissimilar. Female.—Carapace short, well rounded, frontal plates distinct. Eyes three in number, fused on median line, lenses arranged in form of triangle. One or more of free thorax segments fur- nished with paired dorsal plates. Genital segment enlarged, often covered with similar dorsal plates. Body stiff in conse- quence of these plates and not capable of much motion. Abdo- men elongate, often with lateral processes. Anal laminz large THE CRUSTACEA OF NEW JERSEY. ITI and broad, with stout plumose sete. Eggs numerous, uniseriate, and borne in straight cases, visible for their entire length and usually much longer than body. Mouth-tube elongate and taper- ing to sharp point. First maxille lacking, second pair simple flattened laminz, tipped with short claws. Second maxillipeds massive and nodose. All four pairs of legs biramose, and some or all of them lamellar and destitute of plumose sete. Male.—A typical Nogaus form. Carapace more elongate than that of female, and produced posteriorly into better defined lateral lobes. Free segments all well separated, of about same length, but diminishing regularly in width, and none furnished with dorsal plates. Genital segment also without dorsal plates and little enlarged. Abdomen two-jointed. Anal laminz large and foliaceous, furnished with long and stout plumose sete. Adult males are as free swimmers as any of the Caligine and move about with as much ease over their host’s body, thus afford- ing a marked contrast to the fixed females. The young are attached by two broad and ribbon-like filaments, placed side by side and very short. Key to the genera. a. Femazes.

Eyes not evident in adult, visible in young, placed one-third of space from front edge and close together. Second segment with paired dorsal plates broadly elliptical to oval, one-half longer than wide, well inclined from median axis, inner edges nearly straight to concave, widely separated, hardly touch second pair and extend back to center of lateral edges of third pair. Impaired median plate of second segment wide, short, with straight entire hind edge. Third seg- ment with small dorsal plates, almost circular, separated by deep sinus, slightly enlarged at base. From wide separation of first plates second pair entirely visible as seen above. Fourth seg- ment with dorsal plates well enlarged, broader than genital seg- ment and covering front third or two-fifths, well fused with only wide and very shallow posterior sinus. Genital segment elliptical, one-fifth longer than wide, hind lobes broad, evenly rounded, with shallow median sinus. Sixth segment plate small, its edge forms four-fifths of circle, rest narrowed into an an- terior stem or neck where joining genital segment. It projects behind lobes of genital segment for half or two-thirds its length. Anal laminz rather narrow, slender, long as sixth segment plate, acute at tips, and armed with two or three small spines irregu- larly on inner edge, wings entirely absent in adult. Ventral plate of abdomen much wider than sixth segment plate, its hind edge usually evenly rounded. First maxillipeds slender.

Length 8 mm. Male.—Carapace orbicular, wider than long, with lateral mar- gin evenly rounded. Posterior lobes broadly triangular, curved THE CRUSTACEA OF NEW JERSEY. 115 little inward toward median line. Supplementary lobes very short, at least three times wide as long and close to bases of posterior lobes. In preserved material these secondary lobes often turn white or whitish and become opaque. Lateral grooves bent sharply outward at anterior ends, nearly at right angles to lengthwise-axis and end just behind sucking-disks. Frontal plates nearly wide as carapace, project over bases of first an- tennz, thus very prominent. Free thorax segments about same length, diminish greatly in width backwards. Second segment not entirely filling space between hind lobes of carapace, only slightly overlaps inner edges of secondary lobes, its lateral plates broad and enlarged at tip into spathulate form, hind edge nearly straight. Fourth segment one-fifth narrower than genital segment, lateral edges with narrow sharp curve at center. Gen- ital segment elliptical, much longer than wide, with evenly rounded corners. Fifth legs small, blunt, slightly enlarged at tips, carried forward some distance in front of sixth pair. Lat- ter little longer, situated at hind corners and usually curve in- ward toward median line. Inside each and close to its base on hind edge of genital segment a single large spine. Abdomen elongate, longer than wide, two joints of same length, basal spindle-shaped and terminal wedge-shaped with no _protuber- ance between bases of anal laminz.

Terminal claw large and stout, armed on outer edge with two large accessory spines, one near basal and other at center. First maxillipeds with stout basal joint and short slender ter- minal joint, with two accessory claws on inner edge close to base of terminal claw. Ventral of these two claws more than twice size of dorsal. Second maxillipeds much enlarged, rela- tively more so than in female, armed with stout well-developed terminal claw shutting down against group of three tuberculated knobs placed side by side on basal joint. Color as in female, except without pigment spots or blotches and body quite trans- parent. Length 7.23 mm. Remarks.—The above description of the female is from ma- terial collected by Mr. Witmer Stone at Point Pleasant about twenty-five years ago. Twelve examples, all females, were se- cured at that time, and though the host is not given it very likely may have been some shark, such as Mustelus canis? ‘The account of the male as given above is from Wilson’s monograph. Wilson lists the following sharks as hosts for the species: Carcharodon carcharias, Carcharias littoralis, Mustelus cams, Euianuia obscura, Lamna cornubica and Scoliodon terra-nove.

Portion of dorsal plates visible on second thoracic segment inclined out at an angle of forty-five degrees to body axis, their contour elliptical, and longer diameter nearly twice that of shorter diameter. Outer edges of these plates truly extends forward to reniform pads of second maxillipeds, and when removed from body appear spindle-shaped, each end pointed, about twice as long as wide and joined nearly at center of inner margin, leaving both ends free. Wide space between bases of these plates and behind posterior edge of carapace left unprotected or with only small central plate. Dorsal plates of third thorax segment smaller than first pair, elliptical, nearly horizontal or only but slightly inclined, so their tips meet and often overlap in median line. Dorsal plates of third pair some- what enlarged, extend across entire body width, circular, inner edges overlap on median line and their hind edges reach short space over genital segment. Hind edges of first and third pairs of plates scalloped, points ending in short sharp teeth. Edges of second pair of plates smooth. Genital segment about equals carapace in size, evenly rounded in front, lateral edges convex, and hind edge emarginated obliquely each side, forming broad, deep median sinus. Outer hind edge of genital segment ends in short, sharp spine each side. Between this and sinus posterior edge of body sigmoid in form. Abdomen small, plump, barrel- shaped, little longer than wide, one-jointed, and entirely con- cealed below genital segment. Anal laminz short, triangular, with minute irregular spines. First antnnz small, two-jointed, basal joint heavily, and terminal joint lightly, furnished with sete. Basal joint also much wider than terminal and twice as long, its tip reaching well beyond edge of frontal plate. Second antennz small, weak, terminal claw long as rest of appendage, slender and not very strongly curved. Sucking-pads of first pair ovate, and circular second pair much smaller at the base of sec- ond antenne on ventral surface of carapace. Mouth tube and mandibles as usual. Second maxille lamellar, each tipped with long narrow spine. First maxillipeds of usual pattern, terminal claws rather stout, and outer considerably longer than THE CRUSTACEA OF NEW JERSEY. 119 inner. Second maxillipeds swollen, fleshy, terminal joints en- larged as huge, kidney-shaped adhesion pad, without pinchers, knobs or claws. Swimming-legs biramose, each ramus of first two pairs distinctly two-jointed, of third pair partially, and of fourth pair almost entirely fused into single joint. Exopods each armed with stout spines, of similar number and arrange- ment, one at outer distal corner of proximal joint and four as row across end of distal joint. Endopods partly covered with minute papillae or spines. Outside each exopod in three pos- terior pairs small rounded knob, like rudimentary third ramus, bearing on its summit long flexible spine. Basal. joints of each pair of legs subrectangular, increasing greatly in size backward, and those of fourth pair about eight times larger than first. In first two pairs basal joints attached by anterior margins, in third pair by front interior corners, and in fourth pair by centers of interior margins, rami in each case borne on hind margins. In all exopods basal joint much larger than terminal. In endopods of first and second pairs terminal joint larger, and in third and fourth pairs reduced to mere knob on side of basal joint. Fifth legs formed of long papilla, broadly triangular at base and strongly flattened, attached to ventral surface of genital segment half way between lateral margin and median line, with three slender spines. External egg-sacs slender, of even calibre, and reaching length twice rest of body. Color when fresh in alcohol sandy-gray or whitish, without any pigment spots. In life said to be light yellowish-white. Length of body without egg-strings 6 mm., and total length sometimes 18 mm. Remarks.—This species is known to me from New Jersey by the variety stimpsoni described by R. Rathbun, and Leidy’s record of an example taken from the fin of a shark captured at Beesley’s Point. I have every reason to believe that the shark in question is possibly an example in the collection of the Acad- emy, and which I have identified as Eulamia milberti, though Leidy mentions that the host was not determined. Leidy says the cephalothorax is a little smaller than the abdominal segment, and between them are three pairs of dorsal lobes which com- pletely cover the space. The egg-pouches are linear and 0.25 120 REPORT OF NEW JERSEY STATE MUSEUM. mm. thick. Length, 5 mm. In my description given above, I have largely followed the points giver by Wilson in his exhaus- tive account of the species. My examples, eight in number, were all taken from the caudal fin, belly and hind portion of the body of an example of Eulamia milberti secured at Corson’s Inlet, September, 1910, by Dr. R. J. Phillips These parasites were all females, and were found clinging tenaciously to their host, which after being placed in alcohol were easily removed. Where each one was attached a small swelling was noticed on the host. Sub-Family CALIGIN#. Carapace broad, always flattened dorso-ventrally. Free thorax segment without plates or appendages of any sort except fourth pair of legs. Genital segment enlarged, but usually smaller than carapace, and seldom much larger. First and fourth thoracic legs uniramose, second and third biramose, fifth pair rudimen- . tary, but often visible as pair of smal! papillz at hind corners of genital segment. Adults active, most of females, as well as males, capable of swimming about freely. Key to the genera. a. Frontal plates without lunules; second maxille bifurcate or simple; genital segment simple, without plates or processes. LEPEOPHTHEIRUS aa.

Description of female.—Carapace ovate, widest posteriorly, longer than wide. Frontal plates distinct, strongly curved, not quite half width of carapace. Posterior sinuses shallow, wide, well rounded. Median lobe three-eighths entire width, squarely truncated posteriorly, and projecting well back of lateral lobes. Latter short, blunt, straight. Free thoracic segment of medium length, about half wide as genital segment and contracted an- teriorly where it joins carapace. Genital segment slightly obo- vate with gracefully rounded sides and angles, contracted to very short neck before joining abdomen. Latter one-fifth long as genital segment, wider than long, tapering posteriorly, and made up of single joint cut for one-third its length at anus. Anal papillze small, wider than long, with short stout sete. Ege- tubes nearly long as entire body and wide as abdomen, each with seventy-five to eighty eggs. Anterior antenne of medium size, well armed with spines and sete. Posterior antenne rather slender and strongly curved. All other appendages either lamel- late or furnished with lamella somewhere in their structure. Two pairs of maxilla with wide wings either side of central spines. In second maxille though spines well separated and divergent, these wings nearly touch each other at center. First maxilliped with spatulate lamella instead of spine inserted in inner margin of terminal joint near its center. Second maxil- lipeds large, stout, with swollen basal joint furnished on pos- 122 REPORT OF NEW JERSEY STATE MUSEUM. terior ventral margin, where it joins body, with stout tongue-like lamella which projects downward at a right angle to ventral surface. Terminal claw three-quarters as long as basal joint, rather slender, with very long hair-like accessory spine on its inner margin. Furea large, base longer and narrower than branches, and both base and branches strongly flattened into fan-like lamellae. Branches nearly twice wide as long, with radiating ridges and lines extending outward from thickened center. Median sinus triangular, branches so widened toward tip as to nearly meet. First swimming-legs with small spine on end of basal joint pointing outward, and much stouter blunt spine on posterior border of same joint pointing backward. Three claws on terminal joint about equal, with serrated lamellze along their posterior margins. Second legs with wide rounded flange or wing along outer margin of exopod. Fourth legs stout and four-jointed, basal joint swollen and carries slender flexible hair on its outer margin near distal end. Short curved claw at tip of second joint and longer ones on third and fourth joints, flanged on one or both sides with serrate lamine. Fifth legs distinct and of medium size, plainly visible ventrally, but not so dorsally. Color delicate pinkish-yellow, with small pig- mented spots of a purplish or reddish-brown distributed evenly over entire dorsal surface, so that color uniform throughout. Total length, 7.5 mm. Male.—Carapace as in female, except relatively much larger, five-eighths of entire length. Free thoracic segment consider- ably shortened by overlapping of medium lobe of carapace. Gen- ital segment and abdomen together form an almost perfect oval, widest end anterior, while it narrows rapidly posteriorly. Gen- ital segment one-third length of carapace, considerably wider than long, squarely truncated posteriorly, furnished with two pairs of papilla, as one on lateral margins one-third distance from posterior end and other pair at posterior corners. In both pairs papilla sharply conical and with quite large plumose sete. Testes very large, elongate-elliptical in shape, and fill nearly en- tire segment. Semen ducts open on posterior ventral surface, on either side of abdomen. Latter and anal papille similar to THE CRUSTACEA OF NEW JERSEY. 123 those of female. The usual difference in appendages, but while second antennz increased in size not branched as in most species. Instead, at bases two large corrugated ridges of chitin, inclined diagonally, outward from mid line, which serve to prevent slip- ping. Color as in female. Total length, 3.6 mm. (C. B. Wilson. ) Remarks.—This species occurs upon the external surface and always upon the dorsal side of the following fishes: Raya erinacea, Tylosurus marinus, Caranv hippos, Paralichthys den- tatus and P. oblongus. Wilson says: ““When disturbed the males scuttle about over-the surface in a lively manner, but the females ordinarily remain quiet. In the aquarium both sexes swim about freely, but the male is the more lively and usually lives longer. They can be kept more successfully than many other species and do not bother by crawling up out of the water. Females with eggs which are nearly ripe retain the egg strings even under rough treatment, and the nauplii may be reared successfully. The egg cases are separated rather more than usual at their origin in the genital segment. At first they approach each other rapidly until about their own diameter apart, and then extend backward parallel with each other. They are light colored even when well developed, so that it is difficult to judge of their ma- turity by their color. This is due to the paucity of pigment in the larvee.” The species is only known from New Jersey by Wilson’s record from Great Egg Harbor, his material not having’ the identity of the host.

Beach Haven, New Jersey (on young Leptocephalus). Description.—Cephalothorax nearly twice length of breadth, obcordate and proportionately much narrower than in Chalimus scomberi. Frontal segment narrow, not prominent laterally, and biarticulate antennz concealed beneath. Abdomen half length of cephalothorax, shows three conspicuous divisions, and short caudal appendages end in three minute sete. Abdominal feet ending in biramous leaf-like segments fringed with short sete. Rostrum linear and almost long as cephalothorax. Whole length 1.125 mm., of cephalothorax 0.5 mm. (Leidy. ) Remarks.—TVhis species is only known from the above account, having been taken on a larval fish Leptocephalus (Atopichthys), to the tail fin of which it was attached by means of a long fili- form rostrum. In this respect it was thought to resemble Chalimus scomberi as figured by Baird, rather than by Bur- meister. ‘ Family ERGASILID. Head of moderate size, rounded. Antenne formed of five or more articulations. Mouth parts poorly developed. Body ovoid or pyriform in contour, and thorax sometimes much enlarged laterally.

Species numerous, and very difficult to identify. This is due to their extreme variability and plastic nature. Though numer- ous nominal species have been described, but fifteen are admitted by C. D. Marsh in his account of the North American species in 1909. Some of the forms have very wide distribution, ranging over most of North America, Europe and Asia, without exhibit- ing any differences in structure. Only one species included here as identified positively from New Jersey, though doubtless most of those in Marsh’s work will be found eventually. Cyclops serrulatus Fischer. PLATE 34.

Outer edge of each stylet in female with a series of curved hooks or spinules, extends from insertion of outer seta to base. Outer and inner setz shortest, similar. Median pair of sete long, and inner usually twice length of outer, sometimes equals half length of entire animal. All sete more or less plumose, especially dis- tally. Antennz twelve-segmented, last three usually long and slender, and reach back to third or fourth segments. Antennal bristles usually moderate. Swimming-feet with spines as three, four, four, three. Fifth foot one-segmented, plate-like, very strong serrate spine on inner side, at tip very long, slender seta parallel _ to spine, and delicate little seta projects outward on outer side. E.gg-sacs usually long, with many or a few eggs in a spherical mass or sometimes taper to sharp point below, and often stand out from abdomen at wide angle. Color often very dark or dusky, with violet and purple tints in many cases. Length 1.47 mm. Remarks.—A common and abundant species most everywhere, and largely cosmopolitan in distribution. I have found it near Florence and Trenton during the summer of 1912. It is quite variable. Tribe PoDOoPLEA. Mouth furnished with organs developed for mastication, as foot-jaws.

Length 2.3 to 3.6 mm. Remarks.—On June 21st, 1911, this species was taken in great abundance in surface towings in Great Egg Harbor Bay off Ocean City, by Mr. W. B.- Davis and the writer. We found quantities of the megalops of various common crabs, together with the fry of Menidia menidia notata and Syngnathus fuscus, and various medusze, associated. It was also very abundant in Great Bay, in Ocean County, on July Ist to 3d, 1912, when we secured myriads in surface towings. Inland, as far as the salt water extended, we found them in countless numbers, even in the quiet little estuaries. In such places many were eagerly de- voured by the abundant young silversides (Menidia menidia notata). ‘The above description and the accompanying figures were made from examples obtained in Great Bay. Mr. F. J. Keeley has also obtained it in abundance in surface towings off Longport. The coloration of this species is given by most writers as often more or less tinged with light red, and the antennz are often THE CRUSTACEA: OF NEW JERSEY. 133 bright red. It also reaches a rather large size, as Sars says Arctic specimens attain 5 mm. in length. He further adds, “of all the marine Calanoids of Norway this form is by far the most common, often occurring’ in enormous shoals, and thus sometimes giving the sea a conspicuously reddish hue. It is found everywhere in the open’sea, more frequently at the very surface, though at times it may also descend to greater depths, or be carried by the waves and currents towards the shores or into the bays and fjords. * * * It moves rapidly, with abrupt bounds caused by energetic strokes of the natatory legs. At times, however, it is seen quietly suspended in the water, with the anterior antennz spread out to each side at right angles to the body, or proceeding slowly by rapid vibrations of the posterior antennz and the mandibular palps. The male is still more agile than the female, and the motion effected by the pos- terior antennz and mandibular palps is more energetic, in ac- cordance with the somewhat stronger development of these appendages and the pertaining muscles, being changed to a some- what jerky leap through the water. At some seasons male speci- mens are by no means rare, though the female sex always pre- ponderates considerably in number. This Calanoid is eagerly devoured by some of our common food-fishes, for instance the herring and the mackerel and in some cases, as stated by Prof. Rob. Collett, forms almost the exclusive nourishment of one of our great whales, Balenoptera borealis.” Wheeler records it in Vineyard Sound near Gay Head, Martha’s Vineyard, on July roth, 1899, but does not mention it south of that region from the Gulf Stream.? Except possibly for Sharpe’s account, then, the present is the first record of its occur- rence in New Jersey, or so far to the south. It differs from Calanus minor Claus in the shorter furcal bristles, and Calanus princeps Brady in the shorter second antenne. * Crust. Norway, IV, 1903, pp. I0-II. * Bull, U. S. F.

Abdomen broad and long, more than one-third length of rest of body, with well- rounded lateral margins. Anal sinus broad, triangular, cut to center, leaving two lobes sharply pointed and flaring slightly at their tips, papillae small and basal. Swimming-legs long, pro- jecting far beyond carapace, and lobes on basal joints of poste- rior pair small and rectangular.

Remarks.—Found rather abundantly parasitic on the alewife Pomolobus pseudoharengus, and also said to occur on Osmerus eperlanus and Gasterosteus aculeatus. In New Jersey limits it has as yet been found only by Rathbun and Wilson, whose ma- terial was obtained at Great Egg Harbor from unknown hosts. Argulus trilineatus Wilson. PLATE Mile Goldtish Louse. Argulus trilineata Wilson, Proc. U. S. Nat. Mus., XXVII, 1904, p. 651, figs. 34-38. Macon, Georgia (on Carassius auratus). Description—Carapace elliptical, extending well beyond ab- dominal base. Posterior sinus not quite equal to half length of carapace, and a little over twice as long as wide. Antero-lateral sinuses hardly evident. Horseshoe suture long, rather attenuated. First thoracic segment quite short, and all increase in length pos- teriorly till last is several times larger, and thus most of free thorax nearly all exposed. Abdomen spindle-shaped, small, its length one-fourth rest of body and at center its width about two- thirds its own length. Anal sinus excised to center of abdomen, narrowly uniform, and papillze small, basal. Both antennz rather weak, small, and rather well furnished with hooks and spines. Anterior and lateral hooks on basal joint of first antennz slender, and spine on hind border large. End of first antennz slender, not extending beyond lateral hook. Basal joint of second an- tennze equals, though much thicker than two terminal joints, and latter attached obliquely to one of its distal corners, thus two portions of antennz stand nearly at right angles to each other. Basal joint with stout spine on its hind edge, where joining head, and two long ventral slender spines at distal end. Second joint with single long spine on front edge at distal edge, while terminal joint with five or six large stout spines. Spines along either side of median line of body opposite bases of antennz, those on hind edge of basal joints of antennz and lateral hooks on first antennz yellow, and all others colorless and transparent. Eyes small, THE CRUSTACEA OF NEW JERSEY. 137 lunate, mostly inclined to central axis, well forward and widely separated. Sucking-disks small, well anterior, widely separated. Posterior maxillipeds large, well armed. Basal joint of posterior maxillipeds with an oval papillose area, oblique, elevated and covered with short conic spines. ‘Three teeth on hind edge of this joint, stout, acute and long. Second joint with larger papil- lose area on distal end. ‘Third and fourth joints enlarged at distal ends, and whole surfaces below covered with spines and papillz. Terminal joint ends in two curved claws and a fleshy thumb. Swimming-legs all reach well out beyond edge of cara- pace, and two anterior pairs with recurved flagella. Distal joints of all four pairs with a row of plumose setz along posterior edge. Lobes on basal joints of last pair small and well rounded. ‘Tactile papille at opening of oviduct broad and rather well fused with ventral surface of abdomen. Ventral surface of anterior portion of carapace covered with numerous triangular and rather large spines. Color uniform or pale yellowish, slightly deeper along median axis of body, paler about edges. Dorsal surface of thorax with three or four well-defined rows of dark or dusky pigment-spots, strongly contrasted against the yellowish color of the body gen- erally. Length 6 mm. Remarks.——A number of examples were secured June Ist, 1912, by Mr. W. T. Innes, Jr.. They were found attached to the fins of gold fish (Carassius auratus) in captivity in Philadelphia. They were removed from the living fish simply by scraping with a small instrument. Among fish fanciers, and those interested in raising gold fish, these parasites are often very annoying. Sometimes they are very difficult to exterminate, and “‘lousy fish” are never desired by the aquarist. So far as I know it has not yet been found in a wild state in New Jersey, but is often brought into towns and different localities by those interested in aquaria. Some fish fanciers claim that the Argulus, evidently this species, also attaches itself to tadpoles (Rana catesbeiana) when in captivity. . 138 REPORT OF NEW JERSEY STATE MUSEUM.

Powdermill Pond, Warren; Wickaboag and Podunk Ponds at Brookfield; Lake Lashaway between Brookfield and Spencer; Ashley Ponds at Holyoke; Congamon Ponds at Southwick, all in Massa- chusetts (on Esox reticulatus). Description.—Carapace orbicular, long as wide. Antero- lateral sinus shallow or very slight. Posterior sinus rather nar- row, its length a little less than one-third length of carapace, and its width about half its own length. Unlike any other species, the larger chitin ring in the carapace lobes extends forward opposite base of posterior maxillipeds, concave on its inner sur- face at the anterior end, so that into this concavity the other much smaller ring fits, and thus the front of the carapace is clear. Sucking-disks of moderate or medium size, placed near front edge of carapace symmetrically distant about equal to diameter of either. Posterior maxillipeds well armed, medium in size, and somewhat wedge-shaped basal plate with long blunt teeth. Large antenne long, furnished with very long sharp spines and powerful hooks, those at base of second antennz with complement of other smaller ones. Proboscis long and wide, and narrow sting very sharp. Body projects but little beyond the carapace, with the thoracic segments small and the posterior not projecting over the abdomen. Latter ovate, its length about two- sevenths entire length of body, a trifle longer than wide. Very narrow anal sinus slit-like, only extending for about last sixth in length of abdomen. Abdominal papillze subterminal. Swim- ming-legs extend far out beyond edge of carapace and thus very long. Lobes of last pair of swimming-legs of moderate size, boot-shaped and just reaching edge of abdomen. Flagella pres- ent and thickest papilla at oviduct opening of good size. In male second legs with large conical projection on their hind sur- faces at outer end of basal joint. A similar and much smaller one in relative position on third legs. These legs also with THE CRUSTACEA OF NEW JERSEY. 139 rounded knob on front surface of second joint at end next to body, and regular lobes on basal joints of last legs longer and more slender than in female, also separated from joint itself at heel as well as at toe. The colors are quite striking and I cannot do better than to quote. from Wilson, whose account quite agrees with my example: “This is a very clean-looking Argulus, and by far the most beautiful of any American species. It is a veritable Joseph among its brethren in the colors of its coat. The chitin framework and the spines on the ventral surface are a clear orange, the longitudinal ribs of the carapace having the orange bordered by yellow-green. The digestive tube is a deep wine red anteriorly, fading into yellow-green in the abdomen. The testes and semen receptacles are a still deeper red, almost purple. The ground color of the body is a yellow-green, this color forming a wide border around the edge of the carapace and extending inward diagonally as a wide band on either side from the edge just behind the sucking disks to the base of the posterior sinus. From the center of these diagonal bands an- other narrower band of the same color extends backward parallel with the edge of the carapace to near the posterior border of the lobes. At about their center these last bands are joined with the border along the edge by radial bands. In addition to these bands there are areas of the same color just outside the sucking disks and a large one in either lobe opposite the base of the first swimming legs. The rest of the surface is filled in with orange-yellow of various shades, the posterior part of the lobes being tinged with brown, while over the side branches of the stomach it takes more or less of a reddish hue from the stomach contents. As may well be imagined, the whole presents a beautiful variegated appearance, whence the name given to the species. But the most wonderful thing about these beautiful colors is their permanency. ‘They are “‘fast’’ colors in the fullest sense of the word, for they defy any preservative so far tried. Chrome-acetic and corrosive-acetic, Perenyi’s and platinum chloride have no effect upon them, and after preserva- tion in these solutions they have been kept in alcohol for over 140 REPORT OF NEW JERSEY STATE MUSEUM. a year with so little change of color that they can hardly be distinguished from fresh specimens, save for their greater opacity.” Length 6 mm. Remarks.—This species occurs occasionally on Esowx reticu- latus, the common pickerel of New Jersey waters. I have no New Jersey specimens, however, but include the species for the above reason. My description, given above, is drawn up from an example I secured May toth, 1912, which dropped, or was rubbed off of a roach, Abramis crysoleucas, which I angled in the Pocomoke River near Willards, in Maryland. This host was of the usual size, about six inches long, and infested with numerous parasitic protozoa. ‘The species has not been secured, so far as I can find, on any other host than Esox reticulatus, prior to this time. Dr. Wilson observes “they have not been looked for in a single pond where they have not been found, and in all probability they infest this fish more or less through- out its habitat.’ The variegated. and brilliant coloration will distinguish this species from all the others of the genus. 1 Wilson states that by actual experiment they have been found capable of living on red-fin shiners, breams, etc., for a long time. He says the parasites were placed directly upon the red fins. They attached themselves at once, seeming to prefer the neigh- borhood of the dorsal and ventral fins, and, so far as watched, made no attempt to crawl under the opercle. They did not seem to irritate the fish perceptibly, although they could be plainly seen to crowd forward under the scales to pierce the skin. ‘They were kept in this way more than two months. Remaining thus upon the external surface where they could be easily watched, it was seen that the individual parasites changed about consider- ably from one fish to another. One of the red fins proved par- ticularly attractive, and often had nearly all the parasites (fifteen in number) on his body. He was no larger than some of the others, but very plump and vigorous. Although the red fins were fiercely hungry when obtained, having been kept without food since they were caught in the fall, no one of them took any notice of the Arguli, which were placed free in the aquarium for that purpose. Finally one of the parasites fairly rubbed THE. CRUSTACEA OF NEW JERSEY. I4I against a red fin’s nose in swimming about, and the latter, unable to resist such a call, opened his mouth and apparently swallowed the Argulus. But it was only apparently, for in a moment or two the Argulus was forcibly ejected uninjured, and no further attempt was ever made to swallow one. Wilson further states that while the parasite is only known fiom the pickerel (Eso. reticulatus), it may likely be found upon other fish at the breeding-season. According to him, not more than two or three specimens are found upon a single fish, and these always in the gill-cavity. Often it is necessary to examine fifteen to twenty fish before finding a single parasite, so that they could be easily overlooked, and a good summer catch of fish may not reveal their presence. For this reason winter is the best time to secure them upon fish caught through the ice, and as they remain alive for some time after the fish is dead, an entire day’s catch can be looked over. In this manner as many as thirty have been obtained in a single afternoon from three adjacent ponds. Thus far they have not been sought in a single locality without success. When kept in aquaria they are lively, moving about and changing from one fish to another more often than other species. The long plumose sete upon the swimming-legs make powerful oars, and enable them to dart about with great rapidity. One of their favorite movements is to leave the side of the aquarium and, turning back downward, scuttle swiftly along the under side of the surface film of the water after the manner of the very miuch slower aquatic snails. Order CIRRIPEDIA. The Barnacles. Size often considerable. Body imperfectly segmented. Either fixed or parasitic during adult life. Sexes united and sperms motile. Though the barnacles include many genera and species but few have been recorded from New Jersey. Likely many will be added with future collections. In drawing up the present account I have followed the descriptions given by Darwin in his celebrated 142 REPORT OF NEW JERSEY STATE MUSEUM. monograph. These have only been modified to allow compre- hension in variation, etc. The keys are mostly made up from those given by Dr. Henry A. Pilsbry in his studies of this interesting group.

Description.—Capitulum flattened, gradually blends into pe- duncle, summit square, rarely obtusely pointed. Membrane thin. Valves thin, small, variable, always remote and imbedded in membrane. Scuta trilobed, formed of an upper and lower lobe (latter usually widest) joined into straight flat disc, with third lobe projecting out from middle of outer edge and usually bend- ing slightly inward. Form of lateral lobes variable from rounded oblong to equilateral triangle. ‘Terga shape very vari- able, at nearly right angles to scuta. Upper ends of terga imbedded in membrane, projecting freely like little horns about one-third their length. Free projecting portion generally curled inwards and carinal portion more or less outwards. Whole valve generally of nearly equal width, carinal part very little wider. Valve deeply concave internally, with both points gen- erally blunt and rounded. Terga generally about two-thirds length of scuta, rarely only half, and usually separated from apices of scuta by about once their own length, rarely by twice. Terga usually shorter than carina, sometimes very little longer, and distant by third or fourth their own length from apex of carina, rarely by their entire length. Carina lie nearly parallel to scuta, concave within, very slightly bowed, of nearly same width throughout, but with lower third beneath umbo generally . slightly wider than upper part. Carina length varies, usually longer than scuta or terga. Upper and lower points of carina rounded, rarely both ends acuminate. Peduncle flattened, gradually widens as it joins capitulum, to which, generally about equal or a little longer in length. Filamentary appendages six each side, one below basal articula- tion of first cirrus longest and placed on hind edge of a swelling. Second filamentary appendage little lower in side of prosoma, short and thick. Third on hind edge of pedicel of first cirrus above basal articulation, and fourth, fifth and sixth in similar THE CRUSTACEA OF NEW JERSEY. 145 positions on pedicels of third, fourth and fifth cirri.

Some- times minute pectinated tooth between first and second, again second tooth bifid on summit, or still others with fourth rudi- mentary. Maxille with five steps, sometimes each step begins with spine rather larger than others, and at upper angle two large unequal non-pectinated spines, with longer thinner third placed a little below. Outer maxilla simple. Cirri with twice as many segments in sixth cirrus as in first. Spines in first and second cirri doubly serrated. Color of capitulum and peduncle gray, tinged blue, and six black bands, tinged purplish-brown. ‘Two bands near carina be- come confluent on peduncles and sometimes disappear. Carina edged, and interspace between two scuta, colored same dark tint. Whole body and pedicels of cirri dark lead-color, with segments of cirri almost black. Ova white, turning pinkish and then yellow in spirits. Dark bands on capitulum and peduncle become purple or fade, when gray tint disappears. Length of capitulum one inch, and width three-fourths. (Darwin. ) Remarks.—W orld-wide in the sea, and very common on the bottoms of ships. It is found atteached to sea weeds, large sea turtles, large fishes and parasitic copepods on the same, besides other objects. Besides occurring alone, it is often found asso- ciated, according to Darwin, with Conchoderma aurita, Lepas anatifera, Lepas hillii and Lepas anserifera. Known from New Jersey by Leidy’s record. He secured a bunch of seven from a single lernean (Pennella filosa) found on a large sunfish (Mola mola) at Beach Haven. His examples were mostly two inches long. Pilsbry records an example from between Nantucket and Cape Charles on Neptunus sayi. I have already noted an example on Pennella filosa, itself taken on Mola mola (see p. 90). Specimens are in the Academy, labeled New York Harbor. IO MU 146 REPORT OF NEW JERSEY STATE MUSEUM. Sub-Family LEPADIN A. Valves three to five.

Valves generally approximate, excessively thin, brittle, transparent, colorless, smooth. Scuta with lower part of tergo-carinal edge extremely protuberant. Occludent edge more or less but slightly reflexed, with depressed line extending from umbo to apex, basal edge variably much reflexed, at variable angle, or even to a right angle, thus forming an external rim or collar. No distinct internal teeth, but basal edge under umbones more or less distinctly produced into rounded disc or projection, generally not so much outwardly reflexed as rest of basal edge, and no distinct internal basal rim. Primordial valves usually visible, not lying close to basal edge, but a little above. Terga flat, occludent edge slightly arched, not formed of two sides, apex bent towards carina, and width of lower half very variable. Widest part of tergum from two-thirds to equal width of broadest part of carina below its umbo. Carina very variable, part above umbo either spear-shaped and slightly concave within, or nearly flat with central external ridge. Upper part of carina very and equally narrow, deeply concave within, appears as if only central ridge developed. Part below umbo about one-third whole valve length, generally twice, or even thrice, width of upper part. Disc, or lower part, usually slightly concave within, ex- teriorly with or without central ridge, basal edge rounded and lateral edge more or less curved according to form of upper part. Disc not more deeply imbedded in membrane than upper part of valve. Heel or umbo either angular and prominent, or rounded. Very young with carina simply bowed instead of bent rectangularly. Peduncle short, narrow, abruptly inflected all round under basal edges of capitulum, lower part of very variable shape and often suddenly contracted into mere thread which sometimes widens again at extreme end. External membrane very thin, penetrated by usual fine tubuli leading to corium, and wrinkled surface with few or no spines. Peduncle often completely surrounded by yel- lowish ball, sometimes half width of capitulum, formed of very tender vesicular structureless membrane and of pulpy substance. Filamentary appendages five each side, four in pairs at base 148 REPORT OF NEW JERSEY STATE MUSEUM. of first cirrus and one on flanks of prosoma. Mouth with palps accuminated. Mandibles with five teeth, first not far remote from second, and inferior point rather broad and finely pectinated. Maxille with two large unequal upper spines and four regular steps. Posterior cirri with upper parts of segments slightly protuberant. Young with spines of five pairs in two converging lines in upper half of each segment, with numerous minute lateral marginal and interme- diate little bristles. Large examples with all latter so increased that normal five pair indistinguishable, and front of each seg- ment covered by triangular thick brush of bristles, all pointing in same direction. Dorsal tuft on each segment of six or seven large spines with one to three dozen fine ones. First cirrus and anterior ramus of second cirrus with broad brushes and bristles. Pedicels of all cirri thickly covered with bristles. Caudal ap- pendages smooth, with rounded summits. Color in alcohol with front surfaces of segments of cirri and of pedicels purple. Sometimes parts of sack and interspaces be- tween two scuta fine purple. Shell and body said to be pale blue, and cirri spotted with brown, when fresh. Length of capitulum, 1.6 inches; breadth, 1.2. (Darwin. ) Remarks.—Recorded from Beach Haven by Leidy, in 1888, who found it feeding on Cyclops. I have examined examples from Cape May and Atlantic City, the latter obtained by the late John Ford. Mr. Witmer Stone obtained it at Point Pleasant. Widely distributed in most seas. Darwin says it occurs at- tached to fuci, Spirule, Janthinz, Velellas, and often to feathers and cork. He also says it is often associated with the young of Lepas anserifera (var. dilatata), and Lepas pectinata. The yellowish ball, noted above in the description, is said to serve as a buoy to float the animals. Lepas anatifera Linnzus. PLATES 41, 42 AND 44, FIGURES 7, 9, IO. Lepas anatifera Linnzus, Syst.

Description.—Valves white, more or less translucent and thick, tinged bluish-gray from underlying corium, or sometimes brown- ish cream-colored, rarely tinged purple. Surfaces of valves smooth, traces of very fine lines radiating from umbones, some- times rather plain on basal part of scuta. Scuta with occludent edge considerably curved or straight. Internal tooth of right scutum close to umbo varies, either pointed, square or obliquely truncated on either side, or with notch on summit. Internal basal rim of scuta either plainly developed or nearly absent. Often on scuta, or on scuta and terga, nearly straight line diagonally across capitulum of slight quadrilateral depressions, dirty green- ish with edges blending away, and either conspicuous or obsolete. These marks increase in size from umbones to margins of valves. Sometimes two or even three rows on scuta. Margins of valves sometimes slightly notched on line of marks. Interspace between carina and scuta and terga, not wide. Carina convex and smooth, or with knobs or extremely long sharp teeth, exteriorly. Small examples under half an inch generally most strongly barbed. Apex more or less acuminated, width and thickness variable, sides strongly furrowed. Forks generally less wide than broad- est upper part of valve, two prongs diverge from each other at less than right angle, their sharpness and precise form variable, and rim between them reflexed to form slight notch behind. Peduncle smooth, wrinkled, length varies in proportion to that of capitulum, from barely equal to six times as long. Filamentary appendages never more than two each side, sometimes only one, length variable. One placed on flank of prosoma under first cirrus, and second close under basal articulation of this cirrus on hind face of slight swelling. Mandibles with usual fine teeth, all 150 REPORT OF NEW JERSEY STATE MUSEUM. point down. Maxille with lower step of variable width.

New York harbor (on ships’ bottoms). Description—Capitulum more or less elongated relatively to breadth. Valves white, thick, closely approximated and surfaces variably furrowed. ‘erga generally more plainly furrowed than scuta, of which basal portion generally less furrowed than upper part. Ridges often rough, generally much narrower than fur- rows, variable, sometimes alternately wide and narrow, range from eighteen to thirty-two. Scuta with occludent edge rounded, variably protuberant, always leaving rather wide space between edge and ridge running from umbo to pointed apex. Right- hand internal tooth considerably larger than left, which often reduced to mere ridge. Internal basal rim thick, sometimes furrowed along upper edge, thickness variable, sometimes not extending far as basal carinal angle. Terga two-thirds to equal to scuta length. Young with two occludent edges forming right angle with each other. Older examples have form less than right angle, and thus portion of valve so bounded unusually protuberant. Carina deeply concave within, exterior sides finely furrowed longitudinally, generally denticu- lated. Valve only shghtly narrowed in above fork, of which prongs wider than widest part of valve. Rim between prongs reflexed, and heel or external angle just above fork sometimes considerably prominent. Peduncle generally about long as capitulum, generally short in young. Filamentary appendages five usually, sometimes six, on each side. One placed on side of prosoma and four others in pairs below basal articulation of first cirrus. Lowest posterior filament of four generally largest. Young with upper pair of four, often not developed or represented by mere knobs. Cirri with longer ramus of first pair almost equal to shorter arms of second pair, and spine-bearing surfaces only slightly protuberant. Caudal appendages smooth, curved, pointed. White valves edged with bright orange membrane, and so close together that no interspaces left, colored from under- lying corium. Peduncle dark orange-brown, uppermost part 152 REPORT OF NEW JERSEY STATE MUSEUM. under capitulum bright orange all around. Sack internally dark purplish lead-color. Body and cirri nearly white or pale purplish lead-color, with arms of second, third and fourth cirri, and pedicels of fifth and sixth, more or less tinted orange. Fresh ova peach-blossom red, immature ova, in ovarian tubes, pale pink. Capitulum one and one-half inches. (Darwin. ) Remarks.—Common on ships’ bottoms from tropical seas, and distributed world-wide. Also often attached to fuci, pumice, Janthine, Spirule, etc. It is often associated with Lepas anatifera and Lepas Jullii, and in a young state with Lepas fasicularis, according to Darwin. It has been found at Asbury Park, according to Pilsbry. . Lepas pectinata Spengler. PLATES 43 AND 44, Ficures 4, 5, 6, 8. Lepas pectinata Spengler, Skrift. Naturhist.

Harbor of New York (on bottoms of vessels). Leidy, Journ. Acad. Nat. Sci. Phila., (2) III, 1855, p. 151. Atlantic City and Beesley’s Point, New Jersey. Description.—Capitulum variable in length compared with breadth, chiefly due to greater or less production of occludent portion of terga. Valves thin, brittle, variable furrowed sur- face narrow and broad ridges often alternating. Frequently each ridge, especially one extending from umbo to apex of each scutum, sometimes that alone, covered with prominent curled flat calcareous spines, or these sometimes absent. From thin- ness of valves and depths of furrows, edges of valves sinuous. Ridge extending from umbo to apex of scuta unusually promi- nent and curved, runs very close to occludent edge, so that only very narrow space left between this edge and ridge. Internal THE CRUSTACEA OF NEW JERSEY. 153 teeth under umbones either sharp and prominent or mere knobs, sometimes that of right side much larger than left, again equal, or sometimes left scarcely distinguishable. Internal basal rim absent, barely developed. Valves of terga with conspicuous notch to receive apex of scuta, two occludent edges either meet each other at rectangle or at much smaller angle, causing portion thus bounded to vary much in outline, area and degree of prominence. Carina broad, deeply concave within, edges sinu- ous and sometimes strongly barbed externally, narrow above wide fork, which latter wider than widest upper part of valve. Prongs sharp, thin, and rim connecting prongs not, or only slightly, reflexed. Peduncle narrow, shorter than capitulum. Filamentary ap- pendages more or only one, short, obtuse projection on each side, on posterior face of swelling under first cirrus. Man- dibles with inferior point produced into single pectinated tooth, rarely into two pectinated teeth. Palpi very narrow. Maxille very variable, formed of five steps, of which two lower generally united as one, divided by mere trace of notch. Some- times three lower steps blended into irregular projecting sur- face with even fourth step indistinct. First pair of cirri rather far removed from second pair, with longer ramus about three- fourths length of shorter ramus of second cirrus. Spine-bearing surfaces hardly at all protuberant. Lateral marginal spines on posterior cirri rather long. Caudal appendages smooth, rounded, extremely minute. Color in alcohol with sack and cirri, especially first cirrus, clouded with pale purple. Peduncle brownish. Valves bluish in fresh examples. Capitulum six-tenths of an inch long. (Darwin.) . Remarks.—Distributed in the Atlantic Ocean, attached to vari- ous floating objects, as wood, cork, charcoal, seaweed, spirule, bottoms of vessels, bottles, etc. It is sometimes found associated with Lepas anatifera and often with Lepas fascicularis. Leidy found it at Atlantic City and Beesley’s Point. E54 REPORT OF NEW JERSEY STATE MUSEUM. Family BALANIDA. The Acorn Barnacles. No peduncle or stalk developed.

Our coast (East- emiU.. ‘S.)% Description.—Shell in medium and old examples almost in- variably folded lengthwise and irregularly, dirty-white or pale- brown, punctured from outer lamina being corroded. Young with surface usually white and smooth. Shell sometimes much depressed, generally conical, but when crowded together cylin- drical or club-shaped. Isolated examples occasionally become cylindrical. Orifice of shell in elongated examples usually deeply toothed. Radii always narrow, sometimes extremely so, and summits smooth and rounded. Opercular valves like those in next species. Scuta thicker and tips less reflexed, articular ridge 156 REPORT OF NEW JERSEY STATE MUSEUM. rather less prominent and no distinct adductor ridge. Terga often rather narrow, occasionally moderately deep longitudinal furrow, and spur often rather long and pointed. Internally articular ridge prominent and crests for tergal depressor muscles well developed or almost absent. Parietes quite solid or often permeated by minute pores, or small irregular square tubes, which only run up each successive zone of growth for very short dis- tances, giving shell cancellated structure, from which corrosion often externally visible. Lengthwise septa, when present, not denticulated at bases. Internal surface of parietes quite smooth or traversed by very slight anastamosing ridges, but never by regu- lar lengthwise ribs. Carinal margin of each compartment on in- side projects inwards beyond general surface of shell, and running downward rests on basal membrane. Lower edge of sheath rarely hollow. Walls lined by purplish or pale brown, sometimes by almost black corium. Numerous tubuli penetrate under sides of walls and opercular valves and intersection of these tubuli give punctured appearance to often corroded surface of shell. Radit usually very narrow, upper and outer edges as seen externally very oblique, rounded and smooth. Sutural edges either quite smooth or sometimes just perceptibly pitted, like basal margin of walls, or occasionally with globular or arborescent little ridges. Alz very oblique, though sometimes only slightly so, and sutural edges either smooth or obscurely crenated. Basis membranous, minute in pointed specimens. Mouth having labrum with teeth each side of central notch un- usually variable, from two each side, four each side, five one side and four on other, five one side and none on other, and six both sides. Mandibles with fourth and fifth teeth small or rudimentary. Maxillze with scarcely even trace of notch under upper pair of spines. First pair of cirri with one ramus one-third or one-fourth longer than other, segments nine and sixteen in two rami. Second and third cirri short, nearly equal in length, with ten and eleven segments. Sixth cirrus with twenty-five segments, each about broad as long, supporting six pairs of spines. Length 2.5 inches. (Darwin. ) Remarks.—Widely distributed in the north Atlantic Ocean. Very common. It lives attached to rocks, shells and wood, THE CRUSTACEA OF NEW JERSEY. 157 within tidal limits. Darwin says it occurs attached, often con- tinuously coating many square feet of the surface, to rocks, pebbles, wooden piers, littoral shells and ulnz. The most northern point from which he received material was N. Lat. 66° 34’, in North America, and the most southern point was Delaware Bay in Lat. 39°.

Shell conical, generally with parietes rugged and irregularly folded longitudinally, sometimes much depressed and extremely smooth, often cylindrical and very rugged, occasionally club-shaped with upper part much wider than lower, and latter sometimes with extremely narrow parietes like mere ribs, also with wide radii. Orifice in cylindrical varieties often most deeply toothed. Radi generally narrow, with jagged oblique summits, sometimes so nar- row as to form mere linear borders to compartments. Orifice rhomboidal, passing into oval, very deeply or but slightly toothed. Scuta with lines of growth but little prominent, surface generally covered by disintegrating membrane. Upper ends usually little reflexed, so that tips project freely as small flattened points. Articular ridge internally highly prominent and somewhat re- flexed, no adductor ridge, very distinct impression for adductor muscle and depression for lateral depressor muscle small but variable. erga rather small, short spur placed at rather less its own width from basi-scutal angle, and basal edge slopes little towards spur, of which lower end rounded or variably bluntly 158 REPORT OF NEW JERSEY STATE MUSEUM. pointed. No longitudinal furrow, hardly even a depression. Internally articular ridge very prominent in upper part, and variable crest for tergal depressors well developed. Internal carinal edge of each compartment from sheath to basis usually projects little inwards beyond general internal surface of shell. Basal edge of projecting margin rests on calcareous basis and crenated like basal edges of longitudinal parietal septa. Whole internal surface of shell ribbed, but ribs not very prominent. Parietal tubes large, crossed in upper part and often low down by thin transverse septa. Longitudinal parietal septa only slightly denticulated at bases, and occasionally dividing at basis close to outer lamina of parietes, making some short outer sub- ordinate pores. In circular furrow below lower edge of sheath sometimes little ridges dividing into small cells, though some- times this furrow filled up by irregular knobs of calcareous matter. Radii always rather narrow, often form mere linear ribbons of nearly uniform width along edges of compartments. Summits or edges always more or less irregular and jagged. Their septa fine, barely or not at all denticulated. Ala with ob- lique summits, sutural edges rather thick and distinctly crenated. Basis flat, calcareous, very thin, surface slightly marked by radi- ating furrows corresponding to radiating pores in bases of most species. Labrum of mouth with six teeth. Mandibles with fourth tooth minute or rudimentary, and fifth generally confluent with inferior angle. Maxille usually with small notch un- der upper pair of great spines. First pair of cirri with rami very unequal in length, one ramus nearly twice length of other. Segments in two rami of first cirrus ten to twenty-three, or eight to thirteen. Second cirrus with only two or three more segments than shorter ramus of first pair. Third cirrus with one or two more segments than second though decidedly longer. On dorsal surfaces of both segments of pedicel of third cirrus tuft of fine spines. Segments of these three pairs of cirri not much pro- tuberant in front. Segments of posterior cirri have each four, or five, or six pairs of spines. Basal diameter three-quarters of an inch, 1.6 inches in distorted individual. (Darwin. ) THE CRUSTACEA OF NEW JERSEY. 159 Remarks.—A species of very wide distribution. Very com- mon, and usually attached to shells and crustacea in deep water, sometimes on ships’ bottoms. It does not, apparently, attach to rocks uncovered by the tide, though is found on floating timber, sticks, fuci and occasionally on pebbles at the bottom of the sea. Specimens were obtained at Cape May by Mr. C. LeR. Wheeler. It is also known in a fossil state from Canada and Europe. Balanus eburneus Gould. PLATES 47 AND 150, FIGURE I2. Ivory Barnacle.

Description.—Shell conical or almost tubular, white, surface very smooth, covered by thin yellowish epidermis but radii naked. Orifice large, rhomboidal to pentagonal, moderately toothed. Scutum plainly striated longitudinally, teeth on occludent edge small, internally upper surface roughened. Articular ridge promi- nent and slightly or not at all reflexed, pit for adductor muscle distinct, and adductor ridge variably prominent, almost con- fluent with articular ridge. Tergum with basal margin on carinal side of spur sometimes deeply’ or slightly hollowed out, though rarely at all. When much hollowed valve almost two-pronged and carinal prong narrower than spur. No dis- tinct longitudinal furrow on tergum, but whole scutal edge projects above general surface of valve. In carinal edge, in upper part, a remarkable convexity or protuberance in same 160 REPORT OF NEW JERSEY STATE MUSEUM. plane with valve, from which separated by very slight narrow ridge. Spur about one-fourth of valve, lower end abruptly truncated. Internally upper surface much roughened with finely crenated ridges, and distinct crests for depressors cover whole of so-called carinal prong. Compartments have radii and ale with oblique summits, sometimes a little rounded, but not smooth. Septa on sutural edges of radii remarkably fine, closely ap- proximate, and denticuli excessively minute. Sutural edges of ale most delicately crenated. Ale largely added to during diametric growth of shell, and above level of opercular mem- brane. Parietal pores square, rather large, crossed by trans- verse septa almost close down to basis, and longitudinal septa with tolerably large denticuli at bases. Pores in basis crossed by numerous transverse septa. Basis sometimes irregularly cup- formed in group-growing examples. Mouth with serrated labrum, teeth small and decrease in size downwards on each side of central notch. Mandibles with third tooth rather thick, blunt, and fourth and fifth knob-like. Maxillze with inferior part projecting much beyond rest of edge, bears two long single spines, between which and large upper pair in full- sized example about seven pairs of moderately long spines, feathered on their sides. Outer maxille thickly clothed with very fine spines and remarkably prominent. First cirrus with one ramus with twenty-six segments, longer by ten segments than shorter ramus, and both rami of second pair with segments re- markably protuberant in front. Protuberance in upper segments equals length of supporting part of each segment, and rami of second cirri unequal in length by five segments. Third cirrus with segments only slightly protuberant, rami considerably longer than those of second cirrus, and no tuft of fine hairs at dorsal base of pedicel. Sixth pair with upper segments elongated, bear- ing six to seven pairs of spines, and dorsal spines short, thin, few. Average full size about one-inch in basal diameter.

Radi rather narrow, deeply depressed, their summits square and outer lamina on both sides of each suture usually divided into teeth, points of which face and touch each other. These teeth give quite peculiar appearance to shell, sometimes blunt and partially obliterated. Occasionally all six radii perfectly smooth. Radiating parietal septa and de- scending sheath thick, their basal edges plainly seen by naked eye to be dentated with numerous points. ‘Thickness of these plates and sheath varies considerably. Descending sheath not generally perforated, except at sutures by loop- holes for entrance of ribbons of corium. Sheath and inner lamina of parietes together fully equal one-third entire thick- ness of walls. Flattened cavities or tubes run up between parietal septa about two-thirds height of inside of shell. Thick- ness of inner portion of radii varies considerably to generally notched outer lamina. Scutum with’ occludent edge always sinuous, though variable. Terga vary, according to more or less truncated basi-carinal corner. External furrow, marking posi- tion of rudimentary spur, varies in distinctness, chiefly depend- ing upon its nearness to carinal edge of valve. Labrum of mouth sometimes has its teeth worn away. Second pair of cirri relatively shorter and thicker to others. Length 0.55 inches, basal diameter 2.3 inches. (Darwin. ) Remarks.—l have examined several examples from Point Pleasant, secured by Mr. Witmer Stone. This species occurs on our large sea turtles. Doubtless a large loggerhead (Caretta caretta) taken in Delaware Bay near Green Creek several years ago and found more or less covered with rounded plate-like and other barnacles, belonged largely to this species. Mr. H. W. Hand, who gives this information, says the turtle was easily captured. After removing the barnacles and giving a coat of copper paint over the carapace, the liberated turtle swam away with apparent relief. The species does not appear to have ever been recorded from New Jersey previously. It is known from the Mediterranean, west Africa, northeast coast of Australia, the low Archipelago and the Pacific Ocean. It is found attached to large sea-turtles.

Orifice large, nearly hex- agonal. When operculum removed whole inside of cup-formed shell visible at once, as flat membranous base much smaller than orifice. Under side of shell deeply concave. Outside of each compartment formed by broad, rounded and somewhat promi- nent though rarely divided ribs, as transverse ends of folded walls. These ribs closely united together by finely serrated lines of junction. Their outside surfaces delicately striated longi- tudinally, plainly crossed by irregular transverse ridges, especi- ally in lower part of shell. Scuta placed close together at rostral end of orifice, imbedded in brownish tough longitudinally plicated horny substance, which extends far beyond both ends of valves. In outline mitre-shaped, or rounded and sub-triangular, a little curved, more or less elongated, especially in young. ‘erga usually absent or rudi- ment, as short thin plate of shell, barely visible to naked eye, extending parallel and near to tergal edge of scutum. Lips of aperture of sack prominent, highly so towards carinal end. As shell not spreading much at base new folds in walls seldom formed and external longitudinal ribs much more seldom divided. When new folds form, only one formed on one, as rostral, side of each suture, instead of on both sides. Inner ends of folded walls surrounding basal membrane narrow, instead of almost square. Lower edge of sheath, which pro- jects freely, descends almost to level of basal edges of walls. Outer ends of folded walls, forming transverse loops, in- ternally filled up solidly by calcareous matter, instead of by septa forming tubes. Radii little thicker in lower and outer than in upper and inner part of each compartment. In middle not reaching sheath by about half thickness of compartment, consequently separated from plates in which ale rest by large chambers, which extend up nearly to apices of compartments. Sinuous plates forming main portion of compound radi rather thinner and closer together than in some species. Ale thick, thickest medianly and there equal. radii in thickness, almost wedge-formed as lower edges very short compared with upper. THE CRUSTACEA OF NEW JERSEY. 165 Mouth with teeth and fine hairs on labrum sometimes obscure, sometimes plain, and close outside bottom of medial notch small hard prominence. Palps broad, on basal exterior edges short row of spines, not equal in length to width of palps. Mandibles with five main teeth, second and third show only an obscure rudiment of being double. Between these two teeth, and between third and fourth tooth, a small intermediate tooth. Inferior angle narrow, rounded, spinose. End of apodeme of maxille expanded. Pedicel of first cirrus extremely broad, and rami set in an unusually crooked manner. Basal segment of shorter and broader ramus of this cirrus with dorsal surface produced into plate fringed with very fine hairs. Height two inches, diameter two and one-half inches.

Description.—Body unusually stout, without tubercles or spines. Head with large spine pointing anteriorly. Antenne stout, first pair much less than half length of body, second joint much stouter than third and nearly twice as long. Flagellum shorter than peduncle, composed of about twelve segments. Second antennz in adult male about two-thirds long as first and fringed below with numerous long hairs. Hand of first gnatho- pods with palm straight, and armed with pair of spines at well- defined upper angle. Second gnathopods in adult male very short and stout, basal joint several times smaller than hand. 170 REPORT OF NEW JERSEY STATE MUSEUM. Latter turned, strongly convex in front. Palm strongly setose, with strong spine at posterior end and blunt tooth or tubercle near base of finger. Gills nearly round. Three posterior pereeopods stout, carpus wide as long and about one-third length of propodus. Palms of propodi extend nearly to base and de- fined above by pair of spines. Lower margins of third and fourth thoracic segments produced into laminz. Color very variable, sometimes nearly colorless, again reddish or variously mottled. Length of adult female 15 mm. Remarks.—The skeleton shrimp has been recorded from New Jersey several times. According to Holmes the females do not differ greatly from the males in the form of the body, though of much smaller size and have the second antenne, as in the young male, nearly as long as the first. In the female the second gnathopoda are relatively smaller and more slender, the basal joint being several times longer than broad, with the hand more like that of the first gnathopods than in the male. Also the palm has only a small projection’ armed with a spine at the upper end, and devoid of a prominent tubercle near base of dactyl. Young males differ somewhat from the adults. Their antennee are of more nearly equal length with first and second joints of first pair less tumid, gills more oval in outline, hand of second gnathopods less stout, two spinous projections instead of one near upper end of palm, and tubercle near base of dactyl small or absent. The range of the species is from Massachusetts to North Carolina, living among eel-grass.

Terminal uropoda much like preceding pair but stouter. Telson twice as broad as long, distally emarginate, two lobes rounded and armed above with minute hooks. Length 4.4 mm. (Holmes. ) Remarks.—This species was originally described from Great Ege Harbor, and does not seem to have been noticed in our limits since that time: (1817). It lives in tubes, which it car- ries about. 174 REPORT OF NEW JERSEY STATE MUSEUM. According to S$. I. Smith the tubes of all the specimens seen are black externally, thin, very regularly cylindrical, except that they are usually slightly enlarged at one or at both ends. Within they are smoothly lined with a layer of cement, while externally they are covered, to a great extent at least, with minute elongated pellets, apparently the excrement of the animal, arranged trans- versely to the tube and closely crowded together. There appear, however, to be other materials, probably minute fragments of algee, hydroids, etc., mixed with the pellets. The tube is appar- ently never attached, but is carried about by the animal, very much after the manner of the larvee of some species of Phry- ganeidze, as described by Say. It is very difficult to force the living animal from its tube, and it probably never quits the tube voluntarily. The ordinary position of the animal when at rest is with the head only protruding from one end of the tube, the antennule stretched out in front and diverging at about a right angle while the antennz are held out each side at right angles to the tube. The antennulz and antenne are the only appendages which are ordinarily used in locomotion, and by means of these alone the animal appears to move about with its tube with the same ease and rapidity as the species of Podocerus and Corophium do when unencumbered. Ass noticed by Say, the animal turns about within its tube very readily, and uses either end of it indifferently as the front. If the tube catch in any way while the animal is moving about or if it be held fast by forceps, the head is protruded first from one and then the other end of the tube in quick succession, and the antennulz and antenne are thrust along the outside of the tube to discover the obstruction. While thus held fast, fully half the body is often protruded from the tube. In turning about within the tube, the | terminal segments of the pleon are thrust forward beneath the anterior segments and the perzeon pulled back over them, and then the perzeon is folded back upon itself in the same way, but the antennulz, antennze and head are never first bent beneath the pereon. The structure of the telson, second and third uropods, and of a part of the perzeopods is well adapted to the performing of this evolution. The hooks of the second and third uropods and of the telson holding the tail fast to the side of THE CRUSTACEA OF NEW JERSEY. 175 the tube, while the third, fourth and fifth perzeopods, holding on with their opposing hooked tips, pull the posterior part of the perzeon back over the pleon, and then the first gnathopods help to complete the evolution. ‘The tubes are usually kept quite free from foreign growths. He was unable to discover, however, how the diameter of the tube is enlarged to accommodate the growing animal, but thinks it is probably accomplished by build- ing on a larger portion at one end and pulling to pieces the other end until the whole tube is reconstructed. According to Smith, in life, a large portion of the animal ap- pears almost black from the crowding together of numerous specks of very dark purplish pigment. The first segment of the peduncle of the antennula nearly all colored in this way, and broad band of same character at distal end of each of other segments of peduncle. Proximal segments of antenna also dark- colored, and broad band of color at distal end of fourth seg- ment. Other parts of peduncles of antennulz and antenne semi- transparent, and so with flagella. Head and whole anterior and middle portions of body and epimera, more or less colored in same way, as also gnathopods and bases of first and second pereopods. Distal portions of these perzeopods, whole of third, fourth and fifth pairs, and caudal appendages semi-translucent and nearly or quite devoid of pigment. Genus COROPHIUM Latreille.

Inferior antenne very stout in adult male, base compressed laterally, penultimate joint high at base, though distally tapering, armed within with row of spines and sometimes an inferior lobe at proximal end. Same organ also rounded anterior lobe to ante- penultimate joint. Last subcylindrical or slightly tapering joint much narrower though nearly long as preceding joint. Flagel- lum frequently exceeds last basal joint. Inferior antennz in female much more slender than those of male, scarcely com- pressed laterally at bases, penultimate joint hardly tapers, and flagellum and last basal joint like those of male. Anterior enathopoda very robust, form alike in both sexes, with thickened basal joint excavated in front to receive carpus. Latter appears to form part of hand, short. Form of hand with carpus ovoid, though somewhat irregular, and at upper end of palm process with stout spine. Posterior gnathopoda small, with an oblong hand, broadest basally where wide as carpus, and distal end tapers. Palm short, nearly transverse, with angle of hand inside posteriorly produced and hind edge concave above this angle. All along edges of basal joint anteriorly, and both edges of carpus and hand with tufts of long sete. Last pair of parzeo- poda longest, coxal plates wider than deep, and last ones with posterior angle produced, like corresponding segments above. THE CRUSTACEA: OF NEW JERSEY. 181 First and second abdominal segments with sides formed below into an acute tooth posteriorly. Angle of third segment postero- laterally produced as well upturned large hook. Uropods short. Short spine or denticle exserted backward from hind end of peduncle of first pair below rami, and strong spine on inner posterior angle. Rami of first pair of uropoda about two-thirds peduncle in length. Second pair of uropoda with strong spine at inner hind angle of peduncle, but without terminal spine below rami. ‘Terminal uropoda small, short ramus not half length of peduncle. Inner hind angle of peduncle produced lobe extending behind till equal with tip of ramus, producing a biramous ap- pearance. ‘Telson rounded posteriorly, of rather large size. In life color usually bright red, generally mottled with white, some- times latter predominating. Bases of antenne said to be red with orange, and flagella with double row of red spots, one pair to a segment. Length 15 mm. Remarks.—Originally this species was discovered at Great Ege Harbor Bay. It has since been recorded from Beach Haven, and was also obtained some years ago at Point Pleasant by Mr. Witmer Stone. Northward it extends to Labrador. It ranges from low tide water to over five hundred fathoms in depth. Holmes gives its life colors as follows: Body mottled with bright crimson. Head with broad median crimson band, bifurcated in front. First thoracic segment more colored than others. Row of small crimson spots on either side of mid- dorsal line. Bases of both pairs of antenne crowned with orange. Flagella with double rows of crimson spots, pair to each segment. Large hand with crimson blotches. Verrill says it is very common on shelly and roeky bottoms, and although it habitually lives in tubes it does not always con- struct its own tube, but is ready and willing to take possession of any empty worm-tube into which it can get, and having once taken possession it seems to be perfectly at home, for it remains near the end of the tube protruding its stout claw-like antenne, and looking out for its prey, in the most independent manner. It will also frequently leave its tube and swim actively about for a time, and then return to its former tube, or hunt 182 REPORT OF NEW JERSEY STATE MUSEUM. up anew one. It seems, however, to be capable of constructing a tube for itself, when it cannot find suitable ones ready made. It contributes very largely to the food of many fishes, such as scup, pollock, striped bass, etc. Family PONTOPOREIID. Form of body various, compressed to tumid. Cephalon not produced anteriorly in form of hood. Coxal plates moderate in size, generally fringed with bristles, those of fifth pair bilobed.

It is very extensively dis- tributed throughout practically the circum-boreal region. Along the eastern Atlantic shores ranges south to the Mediterranean, on our shores probably south to Virginia, and in the Pacific Ocean well down the shores of both North America and Asia. It appears to be most frequently met with near the shore, though sometimes ranges into water of over fifty fathoms in depth. Verrill says it occurs in great numbers beneath. stones and among the rock-weed near low-water mark. ‘The males are much larger than the females, and sometimes become nearly an inch and a half long. They cannot leap like their cousins that live at high-water mark, but skip actively about on their sides among the stones and gravel, until they reach some shelter, or enter the water, when they swim rapidly in a gyrating man- ner back downward, or sideways. But although they can swim they are seldom met with away from the shore or much below low-water mark.. The zone of Fucus is their true home. Very many examples from Point Pleasant, Great Bay, Ocean City and South Dennis. I have also met with it at Sea Isle City, Corson’s Inlet, Anglesea, Cape May, Town Bank and Dias Creek. Occasionally it is found in the stomachs of smelt (Osmerus eper- lanus) in our markets. I also found it at Parmores Island on the Virginia coast. Gammarus fasciatus Say. PLATE 57. Fresh Water Shrimp.

Brooks of mountains of Pennsylvania, and at Shannon Run, near Bedford Springs. Description.—Body slender, elongate well compressed. Eyes rounded. Cephalon convex, not produced in front. Fourth and fifth body segments slightly angulated at hind edge dorsally, each with three fascicles of moderately long spines, with median fascicle of each segment elevated on distinct protuberance. Sixth segment with lateral and median fascicles of spines. Outer rami of posterior uropoda with terminal segment very narrow, styli- form, devoid of lateral hairs. Inner rami with usually one or two spines on inner edge. Telson divisions with spine and one or two hairs on outer edge, besides few spines and hairs at tip. Superior antennz half length of body, flagellum longer than peduncle, and without hairs. Inferior antennz shorter than superior, peduncle extends far at end of superior, and with long fine hairs. First pair of gnathopoda in male with short trian- gular carpus, with a few hairs. Palm edge of propodus with stout spine on middle of inner side, and two or three smaller spines near tip of retracted dactylus, but no spines on posterior edge proper. In female propodus only slightly narrowed dis- tally, palm edge less oblique than that of male. Hind edge has THE CRUSTACEA] OF NEW JERSEY. 195 several fascicles of hairs, and no spines except cluster near tip of closed dactylus. Second pair of gnathopoda in male with carpus little longer than first pair, and three or four spines on each side near tip of closed dactylus. Second gnathopods of female with carpus and hand smaller than in male, and moderate in length. Perzeopods with long fine hairs posteriorly, and last two pairs of these limbs longest, third pair being shorter than fourth and fifth. Posterior pair of pleopoda with subequal rami, longer than preceding. Color in life mostly pale to translucent brownish, though examples agreeing with Say’s account are met with. These usually show very pale greenish streaks and the appendages with similar-colored blotches. Length 10 to 15 mm. Remarks. — This is our common “fresh-water shrimp” throughout the Middle Atlantic States. It probably occurs also throughout New Jersey, though at present I have met with it only in Cedar Swamp Creek near Petersburg Bridge, Bass River near New Gretna, Alcyon Pond at Pitman, Crooked Run near Cape May Court House, Pensauken, Camden, Florence, Bur- lington and Trenton. In all these localities it was found entirely in fresh water, and seems to be equally abundant throughout the year. I have examined a number of specimens from Staten Island, New York. These were obtained from the water-supply and in springs, by Mr. W. T. Davis. He also obtained it in Terrace Pond, New Jersey. In Pennsylvania it is common in very many sections. My specimens are from Philadelphia, Holmesburg, Bristol, Glad- wynne, Naylor’s Run, Jacoby Creek at Mt. Bethel, Monocacy Creek at Bethlehem and Pocopson. In Delaware I secured it near State Road and at Wilmington. In Maryland it was common at Denton, the Pocomoke River at Willards, Bohemia Manor, Broad Creek and Deer Creek at the Rocks. In Ver- ginia I found it on Chincoteague Island and in Locustville Branch. It is frequently abundant in springs, often in trout streams, and doubtles forms a good portion of the food of many of our predatory fresh-water fishes. Among aquarists it is in demand as fish food. Considerable variation is found 196 REPORT’OF NEW JERSEY STATE, MUSEUM. in this species, many. often being pale or dark, in striking con- trast with others.. ) Possibly Gammarus minus Say is identical with this species, though $. I. Smith says that it is very likely not a true Gamr marus. Say’s account is as follows: Body whitish, with a few pale fulvous lateral spots. Eyes reniform, blackish, placed at the exterior base of the superior antennz. Superior an- tennz obviously longer than inferior ones. Seta [secondary flagellum] short, attaining the tip of the second articulation of the terminal joint [flagellum]. Terminal joint with about twelve articulations. Length three-twentieths of an inch [nearly 4 mm.]. Found in brooks under stones, and may be readily discovered by taking a stone out of the water, and inspecting its inferior surface. Genus ELASMOPUS A. Costa. Elasmopus A. Costa, Rend. della Soc. Reale Borbonica, II, 1853, p. 170 (175)- Type Elasmopus rapax A. Costa, monotypic. Body comparatively strongly built and quite smooth, with coxal plates of moderate size, fourth pair largest and distinctly emarginated posteriorly. Cephalon without any rostrum, with lateral corners rounded off. Eyes well developed. Superior antenne longer than inferior, and provided with comparatively small accessory appendage. Oral parts normal. Gnathopoda subcheliform, rather unequal, posterior ones much larger and very strongly developed in male. Posterior pairs of perzeopoda unusually robust, but joints more or less expanded, and basal one very large and laminar. Last pair of uropoda not very elongated, and somewhat robust in structure, with comparatively broad rami. ‘Telson laminar, divided by deep narrow cleft into two halves, each spinous at tip. 7 Species rather few. This genus is largely characterized by its short robust body, powerful development of the posterior gnathopoda, unusually strongly built posterior pairs of perzo- poda, and structure of last pair of uropoda and that of telson.

Length 9 mm. (Holmes. ) 204 REPORT OF NEW JERSEY STATE, MUSEUM. Remarks.—The range for this animal is from Provincetown, in Massachusetts, south to New Jersey, though no definite record has been given for our limits. It is likely that Smith’s record refers to Great Egg Harbor Bay. The most interesting account is the exhaustive memoir by ‘Holmes, which treats exclusively of this species, from which the following points are gathered. It appears to be not uncommon among seaweed near shore, especially in eel-grass. It is preyed on by small jelly-fish (Gonionemus), to which it falls an easy victim. Its food consists mostly of seaweed and small bits of flesh of most any animal. The swimming of the animal is mainly effected by the pleopoda, though the first impulse is gained by the sudden extension of the abdomen, giving the body a rapid forward movement. The abdomen is then held in an extended position and the pleopods, which then hang at nearly right angles to the body, serve to continue the forward motion. The animal is unable to walk over a plane surface, and out of the water makes indifferent progress by gliding movements pro- duced by alternately flexing and extending the abdomen. It is incapable of leaping like the sand fleas. Its nests are tubular, generally exceeding the animal somewhat in their length. They are constructed upon red seaweeds, or in eel-grass, or Ulva. The nest is open at both ends of uniform diameter, and bits of seaweed are usually woven in. Though frequently leaving the nest, it does not seem to return to its own more readily than to any other, and simply enters the first unoccupied nest it meets with. When established in a nest it is driven out only with difficulty, and it appears to be on the alert to keep out all intruders. Its instinct to remain in the nest when danger threatens is in great contrast to its quickness in flight when roaming about free. A new nest is made in less than an hour. The male carries the female about for a considerable period, and maintains his hold against efforts to dislodge him. with great pertinacity. The female remains remarkably passive when carried about by the male. Her body is usually held quite strongly flexed, the male doing the swimming for both, so that the female is transported as so much dead weight. THE CRUSTACEA OF NEW JERSEY. 205 The Ampithoe punctata of Say is possibly identical. The original account gives the following characters: Eyes ovate, acute and distant above. Clypeus not projecting into an angle. Antenne elongated, first pair two-thirds length of second pair and nearly equal to body, attenuated. Hands not dentated, equal, oval, not larger than carpus. Feet with posterior pair not serrated on hind edge of dilated thighs, but armed with three or four short spines. Body and antennz above, sprinkled with numerous black points, fasciated on abdominal segments. Length rather more than three-tenths of an inch. It was ob- tained several years prior to 1818, at Great Egg Harbor, and was said to be not uncommon. Say’s type was also deposited in the Academy of Natural Sciences of Philadelphia. Should it ever be proved the same, Say’s name will supersede the present name of the species. Ampithoe rubricata (Montagu). PLATE 60. Cancer Gammarus rubricatus Montagu, Trans. Linn. Soc.

Phila., I, 1818, p. 383. Egg Harbor, New Jersey. Amplithoe serrata De Kay, N. Y. Fauna, Crust., VI, 1844, p. 38 (on Say). Description.—Rostrum acute. Eyes large, black, oval, placed at outer base of first antennz, and approximated above. An- tennz equal, short and stout, reach base of sixth segment of body. Hands with about three equidistant prominent spinose teeth on inferior edge of palm, nail or thumb curved, acute and reaching third tooth. Eight, ninth and tenth segments of body serrated, last more conspicuously so. Length two-fifths of an inch. (Say. ) Remarks.—Only known from Say’s account. He adds further on that the species is remarkable for its- large eyes, short and stout antenne, and serrated appearance of hind part of back, occasioned by elevation of tip of each of those segments above the base of the succeeding one. The species has not been redis- covered since Say’s time, when it was secured in Great Egg Harbor. Family ORCHESTIIDZ. Body rather tumid, more or less compressed, metasome and urosome comparatively short and stout. Coxal plates rather large, fourth pair not emarginated posteriorly, and fifth pair THE CRUSTACEA OF NEW JERSEY. 209 deeply bilobed. Cephalon truncated anteriorly, and buccal mass greathy projects inferiorly. Eyes comparatively small, situated near dorsal face of cephalon. Superior antennz generally very much shorter than inferior, without any accessory appendage. Inferior antenne more or less pediform, peduncle rather elong- ated and its basal joint coalesced with cephalon. Anterior lip large, rounded. Epistome applanated. Posterior lip membra- nous, with projecting lateral corners. Mandibles without palps, very powerful, cutting-edge divided into two superposed lamellz which strongly denticulate on edges, molar expansion large and thick, and between both a series of curved sete. First pair of maxille with palp obsolete or nearly so, masticatory lobe well developed and furnished at tip with several strong denticulated spines, basal lobe very narrow, with two short and densely ciliated curved setz at tip. Second pair of maxilla with lobes rather broad and densely setiferous on inner edge. Maxillipeds with masticatory lobes very small and rounded, basal lobes mutch larger and armed at tip with short teeth and bristles. Palp rather large, joints complanated and short hairs at edges. Gnathopoda of various structure, second pair more generally different in two sexes. Perzopoda rather strong, edged with tufts of short spines, three posterior pairs successively increasing in length and having basal joint broad and laminar. Branchial lamellz gen- erally very small and vesicular in form. Pleopoda poorly de- veloped. First two pairs of uropoda strong, with both rami, as also basal part, denticulated. Last pair very small, with only a single minute ramus. ‘Telson short and thick. The members of this family are more or less adapted to a terrestrial life, and when out of the water progress by quick leaps or abrupt hops. Genera several. Of the genus Hyalella, Hyalella knickerbockeri (Bate) was based on specimens in the British Museum received from Say and ascribed to North America, “in brooks, under stones.” Similarly another species, Hyalella sayi (Bate), was also described from North America. Their admission to the fauna of New Jersey has never yet been demonstrated. 14 MU 210 REPORT OF NEW JERSEY STATE MUSEUM. Key to the Genera. a.

Eyes conspicuous. First antennz scarcely extend to penultimate joint of second antennz, and flagellum shorter than peduncle. Second antenne scarcely half body length, stout peduncle in male with last joint little longer than preceding one, though 212 REPORT OF NEW JERSEY STATE MUSEUM. flagellum shorter and of ten to fifteen short compressed joints. First gnathopods in male with carpus produced below into rounded large lobe, distally broadened propodus shorter than carpus, and hind lower angle produced as large rounded lobe, with distal edge formed as palm against which dactyl closes, also deep notch between this lobe and base of dactyl. Second egnathopods in male with very large stout propodus, convex palm very oblique and notched short distance within little pro- duced hind angle. In female carpus and propodus without lobes, though hind edge of former somewhat produced below middle. Second gnathopods of female with oblong propodus rounded below, and minute dactyl on front edge not reaching lower end. Merus and carpus in posterior perzeopods swollen in adult male. Rami of first uropods distinctly shorter than peduncle. Rami of second uropods subequal with peduncle. Rami of third uropods much narrower than thick peduncle, and about as long. Telson more or less pointed, narrowly rounded _ behind, spinulose. Color olive-brown generally. Antennz reddish or reddish-brown. Legs, coxal plates and hind portions of body tinged bluish. Length 10 mm. Remarks.—Distributed along the eastern coast of North America from New Jersey (though it likely ranges southward also) to the Bay of Fundy on the north. It is very common among seaweed, where cast in masses, near the shore or above high-water mark. It appears to seldom occur as far up on the beach as Talitrus, and in the daytime it is more active. It is truly a remarkable leaper, hopping with very great rapidity for a great distance, as compared with its size. In disturbing masses of the seaweed perfect swarms of these beach fleas skip about in all directions. It feeds largely on seaweeds, though will not reject animal food. They are seldom found under masses of drift or seaweeds unless damp, or, if so, is usually buried some distance in the sand. It is a perfectly good swimmer if the occasion necessitates, and is also sometimes strongly attracted to the light. Interesting accounts of this and other species and their phototactic habits are given by Holmes.? *Amer. Journ. Physiology, V, p. 211. THE CRUSTACEA OF NEW JERSEY. 213 Very many examples examined from Point Pleasant, Seaside Park, Holly Beach, and Highland Beach above Cape May. Out- side the State examples were found at Long Beach on Long Island, and on Dewey Beach in Delaware. Mr. W. T.

Lower hind angles of second and third abdominal segments produced into acute triangular points. Rami of first uropods shorter than peduncle. Rami of second uropods subequel to peduncle. Rami of third uropods equal or exceed peduncle, rather large. Telson notched behind, lobes rounded, spinulous. Color olive-brown to olive-green, sometimes reddish-brown. Antenne reddish-brown. Length 18 mm. Remarks.—The distribution is from Cape Cod to Texas. I have New Jersey examples from Point Pleasant and the Manas- quan River banks, secured by Mr. Wilmer Stone. It differs from Orchestia agilis chiefly in its larger size, longer first an- tenne, less robust hand of the second pair of gnathopods of the male, of which palm not lobed, and differently shaped second joint in female gnathopods. It also has a different habitat, living usually around the salt marshes, frequently not near the shore. In such localities it is found among grass and weeds, or under various objects affording refuge for concealment. It also runs or crawls more than Orchestia agilis, and hops less frequently. It is said to live nearly or quite up to the fresh- water, sometimes occurring in almost dry places above high- water marks. Genus TALITRUS Latreille. Talitrus Latreille, Hist. Nat.

Remarks.—Distributed from Cape Cod to New Jersey, where it is abundant on sandy beaches along the seashore. They lie quiet in burrows, indicated by small holes in the sand, all of which are usually found well above the high tide mark. A large example before me is from Spray Beach in Ocean county, and I have also seen others at Cape May and Point Pleasant. They are capable of swimming actively when so forced by high tides. Many undoubtedly fall a prey to the shore birds, fishes and ghost crabs. Mr. W. T. Davis found it on Staten Island, and at Amagansett, Rockaway Beach and at Fire Island on Long Island, New York. Holmes says the burrows they make in the sand are only a few inches deep, and the depth depends on how far the animal has to dig in order to reach moist sand. When dug out in the daylight they are rather sluggish, and apparently dazed. It often curls up © and lies quiet as if feigning death, and may even be picked up and handled in some cases without betraying signs of animation. When aroused it cunningly makes a few leaps, when, especially if it alights upon loose sand, it lies quiet for a short time and then begins to burrow. At night it comes out of its burrows and may be seen in large numbers running over the seaweed recently washed ashore, which affords its principal food. ‘Then it is very alert and is able to detect one’s approach at a distance of several yards. It is strongly attracted to light and gathers around a lantern in swarms. In fact the easiest way to procure a large number of this species is to take a lantern into their midst at 218 REPORT OF NEW JERSEY STATE MUSEUM. night, placing it in the middle of a large blanket or sheet. Those that gather about the lantern may then be collected in quantity and preserved. Talitrus megalophthalmus (Bate). PLATES 64, 65, AND 150, FIGURE 7. Orchestia megalophthalma Bate, Cat. Amph.

Remarks.—Distributed from Maine to New Jersey and found along sandy beaches. I have examined numerous examples from the banks of the Manasquan River, Point Pleasant, Holly Beach, Seaside Park and Highland Beach. It is much less common than Talitrus longicornis, and may be distinguished by its very large eyes and the shape of the second gnathopods in the male. I have also met with it at Chincoteague Island, Vir- ginia. Mr. T. D. Keim has collected it at Sheepshead Bay and Long Beach, on Long Island. Sub-Order ISOPODA. The Isopods. Body flattened dorso-ventrally and composed of three divi- sions, 7. e., a head, a thorax formed of seven segments, and an abdomen of six segments. Sometimes one or two thoracic segments united with head. Eyes usually present, paired, sessile and compound, contiguous or distant. Head appendages two pairs of antenne, pair of maxillipeds, two pairs of maxillze and pair of mandibles. Maxillipeds often provided with an epignath on outside. In parasitic forms mouth-parts strongly modified, some parts entirely disappeared. Appendages of thorax seven pairs of legs, last pair sometimes wanting. Legs of uniform structure and appearance in terrestrial forms, frequently first pair in many forms, and even second, third and fourth pairs differ conspicuously in structure, length and function from suc- ceeding pairs. Six pairs of abdominal appendages, usually five pairs of pleopods and a pair of uropods. Pleopoda some- times natatory, but their function respiratory mostly. Some or all of abdominal segments united. Telson rarely free. Mar- supial plates developed in the female, form an incubating pouch. 220 REPORT OF NEW JERSEY STATE MUSEUM.

Body more or less depressed, oval or oblong in form, and sometimes capable of being rolled into a ball. Cephalon gen- erally small, more or less sunk into first segment of mesosome, showing no true rostral projection, and lateral parts may be more or less expanded. Mesosome formed of seven well-defined and rather uniform segments, with their lateral parts generally expanded to thin fornicate plates. Metasome usually divided into six well-defined segments, lateral plates or epimere, of which some may be expanded similarly to those of mesosome. Usually this not the case with the last, and two anterior seg- ments, which are also usually smaller than three middle ones. First pair of antenne always very small, placed inside second pair, never with more than three joints, and last of which often rudimentary. Second pair of antennz normal, formed by a five-articulated peduncle and a flagellum generally divided into a restricted number of articulations. Length of second antenne moderate, seldom more than half of body length. Buccal mass more or less prominent, and oral parts adapted to biting and THE CRUSTACEA OF NEW JERSEY. oat triturating food. Mandibles strong, always without palps. An- terior maxilla normal, with two masticatory lobes, inner of which with two or three brush-like setz at tip. Posterior max- illa peculiar, laminar, with only very slight indication of sub- division into lobes. Maxillipeds not completely covering oral parts, and terminal part more or less reduced. Marsupial pouch in female formed of four pairs of broad lamella issuing from bases of second to fifth pairs of legs. Appendages of metasome six pairs, five anterior respiratory in character, inner plate of very delicate spongy structure and outer more strongly chitinized, covers inner like an operculum. Sometimes oper- cular plate has on two anterior pairs, more seldom on all pairs, air-cavities or pseudo-trachee. In male inner plate of second and often of first pair, modified to serve for copulative pur- poses. Last pair of appendages represent uropoda, usually biramose, with rami uniarticulate, and project more or less behind. Sars says “The forms of this tribe are generally found in damp situations, beneath leaves, stones or timber, often in great numbers, and feeding, it would seem, on both animal and vegetable matter. They all seem to avoid the full light of day, and some forms even lead a true subterranean existence, in which case the eyes are often rudimentary or wholly absent. As to the respiration, it cannot properly be said to be ex- clusively air-breathing in the same sense as in insects. It is in fact to some extent branchial, and therefore a certain amount of atmospheric moisture is indispensable to their existence. It is for this reason that in very dry weather these animals seem almost wholly to disappear, retiring more or less deeply into crevices and hollows, where some moisture remains.’ The following interesting extract, showing to some extent the part thése animals played in early therapeutics, was kindly forwarded by Dr. Richard J. Phillips: Small beds of this thyme (Thymus citridorus) together with mint are cultivated at Penzance in which to rear millepedes, or * Crust.

The woodlouse, sowpig, or hoglouse, abounds with a nitrous salt which has long found favour for curing scrofulous disease and inveterate struma, as also against some kinds of stone in the bladder. The hoglouse, or millepede, was the primi- tive medicinal pill. It is found in dry gardens under stones, ete., and rolls itself up into a ball when touched. These are also called chiselbobs, and cudworms. From three to twelve were formerly given in Rhenish wine for a hundred days to- gether to cure all kinds of cancers; or they were sometimes worn round the neck in a small bag (which was absurd!). In the Eastern counties they are known as “old sows’ or “St. Anthony’s hogs.”’ Their Latin name is Porcellus scaber. ‘The Welsh call this small creature the “withered old woman of the wood,” “the little pig of the wood,” and “the little grey hog,” also “grammar sows.” Their word “gurach” like “grammar,” means a dried up old dame.

Remarks.—The “pill bug’’ is of world-wide distribution, liv- ing mostly in moist places, as under stones or logs, in crevices or under rocks, about greenhouses, cellars, under boards, ete. It has also been found on floating sea-weed. It is unfortunately classed as injurious to the garden, destroying vegetables grown in greenhouses. It is also said to injure various plants, and be one of the most destructive pests with which the mushroom grower is forced to contend. My examples from South Dennis and Dias Creek, in Cape May county. In Pennsylvania I have found it about Philadelphia, as at Holmesburg, Bustleton, Tor- resdale and Bristol. Mr. W. T.

Legs all ambula- tory. Color above dark brown. Longitudinal row of light yel- low spots on either side of thorax, about at point of junction of epimera with segments. Lateral edges of body light yellowish. Dorsal portion of carapace slightly granular. Length 16 mm. Remarks.—A species of very wide distribution, common in greenhouses, under logs, dead leaves, stones, etc. In New Jer- sey I have found it very abundant in several localities, as at Cape May, South Dennis, Cape May Court House, Camden, Florence and Trenton. It is not very rapid or agile in its movements, though running away deliberately to conceal itself when dis- turbed. In Pennsylvania I have it in Fairmount Park in Phila- delphia, Holmesburg, Bristol and Gladwynne. Mr. W. T. Davis secured it on Staten Island, New York. These animals were at one time used medicinally, according to the American Homceopathic Pharmacopeeia.’ The live animals were crushed and covered with five parts by weight of alcohol, and the mixture allowed to remain eight days in a well-stoppered bottle, in a dark, cool place, being shaken twice a day. The tinc- ture was then poured off, strained and filtered, being then ready HOF USE: *See J. T. Connor, Ed. 2, 1883, p. 350. THE CRUSTACEA OF NEW JERSEY. 297 Super-Family ASELLOIDEA. The Asels. All segments of metasome fused together to form more or less broad shield-like plate, the caudal segment. Pleopoda wholly without swimming-power, exclusively branchial in character, and in considerably reduced number. Usually first pair trans- formed to single opercular plate, and to protect extremely deli- cate succeeding pairs this operculum in male peculiar. Uropoda terminal, never form part of caudal fan, or being of valvular character. Though appendages of metasome quite unserviceable for locomotion, some forms are expert swimmers. This is effected by aid of three posterior pairs of legs being modihed as oar-like swimming implements, by strokes of which the animal is propelled backwards. Form of body greatly variable, some- times very broad and depressed, sometimes slender and elon- gated, approaching to a cylindrical shape. Cephalon always well defined, mesosome showing normal number of segments which sometimes form into two rather distinct sets by means of a median constriction. Coxal plates very small or quite obsolete, never forming marginal area. Superior antenne generally smaller than inferior, which sometimes attain an excessive length. Oral parts normal. Only first pair of legs assume a subcheliform structure. Family ASELLIDA. The Asels. Body more or less broad, depressed, with lateral parts of seg- ments lamellar. Cephalon of moderate size, without any rostrum, lateral parts scarcely expanded. Caudal segment large. Shield-like eyes, when present, small and lateral. Both pairs of antenne with multiarticulate flagella, superior ones much smaller than inferior and issuing close together. Oral parts normal. Legs ambulatory, except first pair, which distinctly subcheliform. 238 REPORT OF NEW JERSEY STATE, MUSEUM. Pleopoda in female in four pairs, first very small, not operculi- form, consisting each of single rounded lamella. Three succeed- ing pairs biramous, with both rami lamelliform, outer lamella of second pair very large and incrusted, and forming together with corresponding lamella of other side sort of operculum, com- pletely covering two succeeding pairs. Pleopoda in male of five pairs, an additional very small pair, forming copulative append- ages, interposed between first and second. Uropoda compara- tively large, biramous, rami styliform or lamellar. Genera about four, and most of them entirely fresh-water in habitat. Genus ASELLUS G. St. Hilaire. The Asels. Asellus G.

Second segment of first antennze one and one-half times longer than first segment, and third segment three-fourths leneth of second. Flagellum formed of fourteen segments, and reaches end of peduncle of second antennz. Second antenne with first three segments short, subequal, fourth segment long as combined length of first three, and fifth segment one and two- ‘thirds longer than fourth. Flagellum formed of about ninety segments, and reaches hind edge of fifth thoracic segment. 240 REPORT OF NEW JERSEY STATE MUSEUM. Maxillipeds with palp of five segments.

Abdomen formed of two short segments, seen only in middle of dorsal surface, and large terminal segment, its hind lateral angles rounded and hind edge slightly produced as broad triangular process between uropoda. Latter about long as terminal abdominal segment, and peduncle about long as inner rami, which latter broad and tapering narrowly to acute end. Outer rami of uropoda about half width of inner, also tapering to narrow pointed end. Female with first pleopoda attached close together. First pair of legs prehensile, with propodus greatly expanded, and lower edge pro- duced in one long and one short triangular process. All other legs ambulatory. Color brownish above, much paler below. Above spotted and mottled more or less in some specimens, with dull yellowish tints. Length (without uropoda and antenne) T5 mm. Remarks.—This usually abundant species in most of our fresh waters ranges from Massachusetts to Virginia, Mississippi and Michigan. It is most frequently found in quiet water, as pools, ponds and lakes, or slow-running streams, under stones. In this State I have found it common, sometimes in great numbers at various of the following places: Cold Spring Inlet, Nummy Town, Fishing Creek, Pond Creek, New England Creek, Coxe’s. Hall Creek, Goshen Creek, Crooked Creek at Cape May Court House, Dennis Creek near South Dennis, Dennisville, Dias. Creek, Palermo, Cedar Swamp Creek, Bridgeton, Pitman, Mantua, Wenonah, Camden, Pensauken, Turnersville, Berlin, Atco, Hammonton, Speedwell, Delanco, Burlington, Florence, Trenton and Lake Hopatcong. Mr. W. T. Davis found it at Ter- race Pond, and says it is common in most ponds and slow-flowing brooks of Staten Island, New York. The following notes and associations which I have gathered may be interesting. Abundant with Gammarus fasciatus, Umbra pygmea, Fundulus heteroclitus macrolepidotus and F. diaphanus in Crooked Creek THE CRUSTACEA OF NEW JERSEY. = 241 at Cape May Court House, on January 5th, 1908. Later the same day we also found it abundant in Great Sound Creek with Umbra, Fundulus heteroclitus macrolepidotus and Apeltes quad- racus. Common in Repaupo Creek at Repaupo, April 19th, 1908, with Anguilla chrisypa, Ameiurus nebulosus, Umbra pygmea, Aphre- doderus sayanus and Enneacanthus gloriosus. Abundant in Chestnut Branch at Pitman, Gloucester County, October rst, 1909, with Anguilla chrisypa, Semotilus bullarts, Notropis cornutus, Erimyzon sucetta oblongus, Schilbeodes gyrinus, Umbra pygmea, Fundulus heteroclitus macrolepidotus, F. diaphanus, Enneacanthus gloriosus, Ewpomotis gibbosus and Boleosoma mgrum olmstedt. Abundant October 24th, 1909, at McPherson’s Branch of Pond Creek, near Cape May, with Gammarus fasciatus, Umbra pygmea, Fundulus heteroclitus macrolepdiotus and Gambusia gracilis. We also found it the same day in New England Creek with Gammarus, Gambusia and Eupomotis gibbosus, and in Fish- ing Creek with Gammarus, Abramis crysoleucas, Umbra pygmea, Aphredoderus, Enneacanthus gloriosus and Eupomotis. On December 5th, tg909, Mr. T. D. Keim reports it abundant at Brookdale in Notch Creek, from where the Boonton Aqueduct crosses the Morris Canal till about one mile below. ‘This is interesting as most of the following were dug out of leaves in the mud, though the upper end of the stream was coated with ice. Besides Gammarus fasciatus, the only other crustacean noted, the entire list of vertebrates was as follows: Petromyzon marinus, Abramis crysoleucas, Notropis bifrenatus, N. cornutus, Rhinichthys atronasus, Catostomus commersonni, Erimyzon sucetta oblongus, Ameiurus nebulosus, Schilbeodes gyrinus, Esox reticulatus, Umbra pygmea, Acantharchus pomotis, Ambloplites rupestris, Lepomis auritus, Eupomotis gibbosus, Perca flavescens, Boleosoma nigrum olmstedi, Desmognathus fusca, Acris gryllus crepitans, Rana clamata, R. palustris and Thamnophis sirtalis. On October 13th, 1911, it was very abundant with Gammarus fasciatus, Anguilla chrisypa, Fundulus heteroclitus macrolepid- otus, F. diaphanus and Apeltes quadracus in Crooked Creek at 16 MU 242 REPORT OF NEW JERSEY STATE MUSEUM. Cape May Court House. On October 14th it was exceedingly abundant, associated with Gammarus fasciatus and Notonectes, in the fresh-water ditches tributary to Dias Creek near the village of the same name. On December 2d, 1911, it was common at Bridgeton with Palemonetes vulgaris, Gammarus fasciatus, Planorbis trivolvis, Physa heterostropha, Somatogyrus altilis, Unio complanata and Anodonta cataracte, the mollusca identified by Mr. E. G. Van- atta. Super-Family BOPYROIDEA. Female.—Often conspicuously asymmetrical, even when body segmentation is apparent. In latter case three chief divisions, as cephalon, mesosome and metasome may be distinguished, though each not very sharply defined. Cephalon generally car- ries in front two pairs of rudimentary antenne, and produced below to conic prominence exhibiting on tip of oral aperture. Oral parts much reduced, only mandibles and maxillipeds dis- tinctly developed, with former styliform and converging to oral orifice, and latter lamelliform. Legs, when present, all alike, prehensile, terminating in a minute hand. Pleopoda sometimes rather large, all branchial in character, while in larve natatory. Uropoda, when present, always very small and simple, not form- ing with last segment a caudal fan. Male.—Of diminutive size, and generally found clinging to genital region of female like a parasite. Appearance also very different from that of female, retaining several larval characters, and sometimes not differing from last larval stage except by presence of generative organs. Remarks.—Parasitic forms, found on other crustacea of dif- ferent orders. ‘They represent the most degraded isopods, some- times the fully-grown female being a simple sac filled with ova, without any trace of segmentation or of limbs. All forms show a more or less pronounced, regressive metamorphosis, comprising at least two distinct larval stages, very dissimilar in both general appearance and in structure of the several appendages, and equally THE CRUSTACEA OF NEW JERSEY. 243 different from adult animals. Probably in most forms even a third intermediate larval stage (the microniscus stage) occurs. Sexual dimorphism very pronounced in all forms. Sometimes the parasite penetrates to the inner organs of its host, looking merely like an endoparasite, and in all such cases the body of the female is found to be greatly deformed. The resemblance of certain of the Cymothoidea to these ani- mals was thought by some to express relationship. As now generally contended, their similarity is more likely due to para- sitic habits, their structural characters indicating them of but remote relation, and no trace of annectant forms has been dis- covered. No less than seven families have been proposed, but as several of these are said to represent only different transitory larval stages, thus only four families are all Sars admits. These families were framed originally more with reference to the host on which the bopyroid was parasitic, as Microniscide on Copepoda, Cyproniscidze on Ostracoda, Dajidee on Schizopoda, Cabiropside on Isopoda and Amphipoda, Cryptoniscide on Cirripedia, Entoniscide on Brachyura and Bopyride on deca- podous crustacea. Family BOPYRIDE. Body of female distinctly segmented, more or less asym- metrical, twisted now to right, now to left, and dorsal face flat- tened. Cephalon deeply sunk into mesosome, carries in front two pairs of rudimentary antenne. Eyes, when present, dorsal. Maxillipeds lamellar, biarticulate, obtecting oral area _ below, more frequently showing small terminal joint, and at base two curved lanceolate appendages (epignaths). Legs seven pairs, sometimes obsolete on one side, and all of same structure, short, prehensile. Coxal plates obsolete or distinctly defined. In- cubatory plates five pairs, more or less arching over ventral face of mesosome. First pair usually concealed by second and di- vided by transversal fold into two segments, of which distal one projects freely within incubatory cavity. Metasome more or less distinctly segmented, pleopoda, forming simple or double 244 REPORT OF NEW JERSEY STATE MUSEUM. lamellze, all of same structure, rarely obsolete. _Uropoda, when present, simple, lanceolate. Male more or less slender, perfectly symmetrical, with cephalon evenly rounded in front, and all seg- ments of mesosome sharply defined, those of metasome some- times distinct, sometimes confluent. Last larval stage with mouth simple, conic. Posterior antennz with flagellum quadri- articulate. Legs of uniform structure. Uropoda with inner ramus shorter than outer.

He says it is not a very abundant parasite, and after having accidentally found a speci- men, fifty fiddler crabs were destroyed in a search for other examples, without any more having been found. ‘The parasite produces no deformity, visible externally, of the animal it infests. The male was found in the embrace of the female. So far it seems to occur only in the fiddler crab, Uca pugilator. Super-Family IDOTHEOIDEA. Uropoda lateral, valve-like, ventrally placed, closing over five pairs of branchial pleopoda attached on outer edges to sides of terminal segment and opening and closing like folding doors.

Description.—Body oblong, ovate, almost three times long as broad. Abdomen length equals little more than one-third length of entire body. Head about twice as wide as long, front deeply emarginate between anterior lateral angles, and latter conspicu- ous and acute. Eyes composite, large, rounded, placed medianly THE CRUSTACEA OF NEW JERSEY. 251 on extreme lateral margins of head. Head above, from front to hind edges, with prominent elevation bearing two tubercles, one each side of median line, which appear, as viewed dorsally, to project forward beyond frontal excavation. First antennze with basal segment large and somewhat expanded, second and third subequal segments only little shorter than first, and fourth segment little longer than third. First antennz reach to end of second segment of second antennz. First segment of second antenne short, second long segment equals third and also equals first two segments of first pair of antennz, fourth segment nearly twice length of third, and fifth segment shorter than fourth or only about one and one-half times longer than third. Flagellum of second antennz about as long as fourth segment of same organ. Retracted second antennz reach to hind edge of fifth thoracic segment. Maxillipeds with palp of four segments. Second, third and fourth thoracic segments trifle © longer than others, which latter subequal. First two thoracic segments with lateral parts formed into very acute processes, as a single process on each side of segments. Acutely produced epimeron lies closely anterior to each of processes mentioned, though below lateral part of segment in a lower plane. Epi- meron of second segment bilobate, and as seen dorsally conceals very acute lower lobe. Third and fourth thoracic segments with lateral portions produced on each side as two acute processes, as one larger and anterior, and a smaller posterior. Epimera of these segments inconspicuous, small, acute, placed just below lateral parts about middle of segment. Last three segments with anterior portions acutely produced, acute epimeron occupying rest of lateral edge, and posterior half of lateral portion of segment not produced. On each side of first four thoracic segments small tubercle near hind edge in median line. Abdomen formed of a single segment and about one-third distance from base to end each side of lateral edge, produced in acute triangular pro- cess. Also about two-thirds distance from base to end sides of abdomen angulate, and from this point lateral edges rapidly con- verge to triangulate end, which latter rounded posteriorly. Legs mostly of similar structure. Color usually dull neutral tint, and 252 REPORT OF NEW JERSEY STATE MUSEUM. though without bright markings, sometimes varied with brown or reddish tints which fade out in alcohol. Length 11 mm. Remarks.—Originally described from Great Egg Harbor, where it -was found with /dotea balthica. It ranges north to Massachusetts, and south to Florida and the Bahamas. It lives in tide-pools, among eel-grass or algze, sand, gravel, etc. It has been taken from four and one-half to eighteen fathoms in depth. Verrill says it lives among the Corallina and other alge in the tide-pools. Its colors are equally variable with those of the other species, and are often variously shaded brown, dull reddish or light red, colors well adapted to blend with the colors of the Corallines. Mr. Witmer Stone secured it at Point Pleasant. Erichsonella attenuata (Harger). PLATE 77. Erichsonia attenuata Harger, Rep. U. S. F. Com. I, 1871-72 (1873), p. 570, Pl. 6, fig. 27.

Eyes composite, small, placed laterally or at sides of head, and midway between front and hind edges. A pronounced elevation on head between THE CRUSTACEA OF NEW JERSEY. 253 eyes. First antenne with basal segment large, somewhat ex- panded, second segment little shorter than first and about half its width, third and fourth equal segments, each one and one- half longer than second. First antennze reach middle of third segment of peduncle of second antenne. First segment of second antennze short and inconspicuous as viewed dorsally, second segment long or about three times longer than first, third segment about one and one-half times longer than second, fourth segment about one and one-half times longer than third, and fifth segment a little less than fourth. Flagellum a little longer than fifth segment of second attennz, and latter longer than half of entire body length. Maxillipeds with palp formed of four seg- ments. First thoracic segment a little shorter than any of others except seventh. Second, third, fourth and fifth thoracic segments subequal. Epimera distinctly separate on all segments, including first, very small or almost inconspicuous and situated in first three segments on lateral edge anterior to median trans- verse line, though in fourth segment they occupy middle of lateral margin. In last four segments epimera placed below medi- an transverse line, and give to all segments rather angular ap- pearance. Abdomen formed of a single segment, and about one-third distance from base to posterior end, a small lateral process on either side. Below these processes sides of abdomen nearly parallel till close to end where they form rounded apex. Color (in alcohol) light yellowish-gray with minute blackish dots. Length 15 mm. (O. Harger and H. Richardson.) Remarks.—Originally found in Great Ege Harbor Bay, in this State, and subsequently in Connecticut, the species is seen to have a restricted distribution. It does not appear to be common, and was found in the eel-grass. Leidy records it from Beach Haven. Genus EDOTIA Guérin-Ménéville. Edotia Guérin-Ménville, Iconogr.

Sometimes only a single marginal streak present. Colors arranged in blotches or transverse bands occasionally. Length 20 mm. Remarks.—Abundant on the New Jersey coast, and elsewhere very widely distributed, ranging along the Atlantic coast of North America from the Gulf of St. Lawrence to North Caro- lina, Bermuda, Barbadoes and South America. It also occurs in many regions of the Old World, if all the described forms are synonyms. Its known bathymetric range is from the surface to a depth of one hundred and nineteen fathoms. It lives on the surface of the sea among floating objects, as grass, seaweed, etc., and among eel-grass and algz. Along the seashore it occurs in gravel and sand. It forms the food of some fishes, having been taken from the stomach of the smelt (Osmerus eperlanus). 260 REPORT OF NEW JERSEY STATE MUSEUM. I have met with it at Ocean City, Seaside Park, Sea Isle City, Stone Harbor, Anglesea and Cape May. Mr. Witmer Stone found it at Point Pleasant. It also occurs along the coast of Delaware at Lewes, Rehoboth and Indian River Inlet. In Virginia I found it at Assateague and Cedar Island. Mr. W. T. Davis notes it from Staten Island, New York.

Remarks.—This southern form was originally discovered on the coast of Georgia, and its range is now known to extend from southern Florida to Massachusetts. It lives among eel- grass or algz, or rocks, often where the latter are dark and covered with barnacles. Say found it very numerous on the THE CRUSTACEA OF NEW JERSEY. 269 beach of Saint Catherine’s Island in Georgia. ‘They concealed themselves under raised bark, and in the deserted holes of Teredo, etc., of such trees as are periodically immersed. This species suggests the “pill-bugs” in form as well as habits. Verrill says it occurs in abundance under stones and rocks, or creeping slowly about among the branches and roots of sea- weeds, on their sides and upper surfaces, from low-water mark nearly up to high-water mark. In color it is exceedingly variable, for no two can be found alike. The colors consist of irregular blotches and dashes of dark gray, light gray, slate, greenish and white, so blended as to imitate very closely the colors of the barnacles and gray surfaces of the rocks where they live. When disturbed they curl themselves up into a ball and drop to the bottom. My examples from Cape May. Mr. W. T. Davis reports he found it at Center Island in Oyster Bay, Long Island, New York.

Remarks.—This species is well known on account of its de- structiveness to submerged timber. It has a wide distribution from Florida to Nova Scotia, Europe, and in the Pacific Ocean. Harger says much has been written upon its destructive habits and the means of preventing its attacks on woodwork, for which the reader may consult especially the publications of Leach, Coldstream, Hope, Thompson, Moore, Gould, Bate and West- wood, Verrill, and Andrews, who has observed it attacking the gutta percha of submarine telegraph cables. It lives above low- water mark, though usually not far below, having been taken in at least ten fathoms. In New Jersey it is recorded from Great Egg Harbor and Absecon. Famly CYMOTHOID-.

Remarks.—This species is found along the Atlantic coast of North America from Connecticut southward to Cozumel and the West Indies. Though I have no New Jersey specimens, it is included, as I have seen it at Cape May several years ago. Mr. T. D. Keim and myself seined numbers of small mullets (ugil cephalus and Mugil curema) on the ocean beach just below Rehoboth, Delaware, on October 12th, 1910. After examining the fishes and selecting a number, the rest were turned adrift in the sea water. Then as we were about to lift our seine, numbers of these small isopods were found in the moist sands, left ap- parently by the receding water. ‘They were all crawling about, and we scooped up a number of them, which are now before me I mention this fact as the species is said to be parasitic on young mullet, though none of the great numbers of the latter contained any whatever. Possibly the disturbance caused by the capture of the fish had induced the parasites to let their hosts go? [| have never seen them on the squids, though have often searched for them. In the United States this species is only recorded from Con- necticut, Maryland, North Carolina and Florida. The above notices, therefore would indicate its admission to New Jersey as well as Delaware. Genus LIVONECA Leach. Livoneca Leach, Dict. Sci. Nat., XII, 1818, p. 351. Type Livoneca redmanit Leach, first species. THE CRUSTACEA OF NEW JERSEY. 279 Body suboval, more or less twisted. Head most always deeply immersed in first thoracic segment, not produced pos- teriorly in three lobes. Thoracic segments either equal in length, or first one abruptly longer and last one abruptly shorter tian others. Anterior edge of first thoracic segment not trisinuate, widely sinuated in middle and more or less sinuated or incised at antero-lateral angles.

Description.—Body ovate, broad, about one and two-thirds longer than wide. Head broad as long, narrower in front than behind and front widely convex. Eyes indistinct, small, placed in hind lateral angles of head. Hind edge of head rounded. First antenne formed of six or seven segments and reach front lateral angles of first thoracic segment, but not to hind edge of head. Second antennze formed of eight or nine segments and reach hind edge of head. Maxillipeds with palp of two segments. First five thoracic segments subequal, and sixth and seventh also subequal, each a little shorter than any of preceding segments. Epimera distinctly separated on all segments except first, and comprise entire lateral edge in second, third, fourth and fifth segments. In sixth and seventh segments hind ends produced beyond hind edges of segments considerably. All six abdominal segments distinct. Abdomen not immersed or set in thorax, also not abruptly narrower than latter, and first abdominal segment wide as seventh thoracic segment, though segments gradually decreasing in width. Sixth or terminal abdominal segment rounded behind. Uropoda not reaching end of terminal abdominal segment, both branches of equal length and similar shape. Outer branch of uropoda rounded behind, about half width of inner, both branches of equal width through- out their length, and inner branch obliquely truncate with posterior lateral angles rounded. Legs all prehensile, with well curved dactyli. No carina on basis of any of legs. Color pale brown, and transverse yellowish band along posterior edges of all segments. Epimera also yellow. Length 21 mm. Remarks.—A very familiar parasite on many of our larger fishes, and ranging from Mississippi and Florida north to THE CRUSTACEA OF NEW JERSEY. 281 Massachusetts. It is usually found clinging to the gills, or under surface of the opercular region, in the gill-opening of its host. The hosts now given are Pristis semisagittatus, Trachurops crumenophthalmus, Pomatomus saltatrix, Stenotomus chrysops, Cynoscion regalis?, Lagodon rhomboides and Micropogon un- dulatus. Of all these it is most numerous in the gill-opening of young Pomatomus, and in some places along our shores these fish are sometimes angled by seashore excursionists for the amuse- ment and excitement of locating as many “bugs” as possible. They are sometime present in most every individual taken, and a whole day’s catch may reveal as many parasites as fish, some- times two or three in rare instances on a single host. I have ex- amined a number of specimens from Barnegat Pier, Atlantic City, Ocean City and Cape May. Mr. W. T. Davis secured one from Tautoga onitis near New York City, which I have also seen.

It is parasitic on species of flying fish, as Exonautes exiliens and Exonautes rondeletu, also on the dolphin, Coryphena. It has not been secured in New Jersey since the type was found in 1818, though is doubtless very abundant off shore. Genus OLENCIRA Leach. Olenctra Leach, Dict. Sci. Nat., XII, 1818, p. 351.

Ab- domen abruptly narrower than thorax, first segment deeply set in thorax and covered at sides by seventh thoracic segment. Following first segment others but slightly increasing in breadth. Sixth or terminal abdominal segment little longer than broad, triangularly produced to narrowly rounded apex. All legs pre- hensile, with long, narrow curved dactyls. Legs increase slightly in length to seventh pair, which abruptly much larger and longer than sixth pair, being greatly lengthened. Last three pairs of legs have basis furnished with low carina. Color gray- ish. Length 26 mm. Remarks.—Historically, as well as otherwise in many ways, this is a most interesting isopod. It was originally the subject of a memoir by Latrobe, who was also the first to make known its host, Brevortia tyannus. So impressed was Latrobe with the habit of this parasite of living in the mouth of its host, that with graceful fancy he coined the specific names in the same vein for both. The parasite he names with reference to the old Roman pregustatores whose duty it was to taste of the food for their rulers, the 7yranni, and thus insure against poison. ‘The parasite is certainly a remarkable creature, as seen clasped to the tongue of its host and surrounded by the myriad of fine gill-rakers. It no doubt finds an ample food supply in the minute herbivorous food of its host. In New Jersey it has only been seen occasionally in the mouths of menhaden taken about Cape May, though it doubtless occurs in many other places along the coast, or in fact wherever its host may roam. I have examined a large old dried example received from Thomas Say, likely from our shores? 286 REPORT OF NEW JERSEY STATE. MUSEUM. Genus NEROCILA Leach. Nerocila Leach, Dict. Sci.

Eyes small, round, compound, placed in hind lateral angles of head. First pair of antenne composed of eight joints, reach to middle of first thoracic segment. Second pair of antenne formed of THE CRUSTACEA OF NEW JERSEY. 287 twelve joints, extends one or two joints beyond first antenne, last four joints very slender and gradually diminishing in size and length. Maxilliped with palp of two joints. Mandible with palp of three joints. ‘Thorax widest at fifth and sixth segments, which also longer than others. Hind lateral angles of three last segments acutely produced, and extend beyond epimera. Latter distinct on all segments, except first. First three small, first two with hind edges rounded. Last four acutely produced, epimera extending to hind edges of segments, but not to end of hind lateral angles in last three segments.

Remarks.—This species was previously only known from Wood's Holl and Vineyard Sound, if Nerocila lanceolata (Say) is really distinct, as contended. If the latter proves identical, however, the southern range would extend to Georgia. At present Nerocila munda Harger is now known for the first time south of New England, as well as an addition to the fauna of New Jersey. Previously it appears to only have been found on the dorsal fin of the file fish (Alutera schepfi).

Head widest portion of body, narrowed in front, posterior edge slightly concave medianly, as seen above anterior lateral edges concave, and front edge ends in minute rostrum. Eyes and lobes large, latter placed in deep recesses in anterior lateral portion of head. First antenne of three segments, basal segment somewhat longer than combined length of others and small knob or rudimentary flagellum terminal. Male with first antennz usually about equal to head length with first free thoracic segment, but sometimes considerably longer. Female with first antennz about equal to head length alone. Second antennz lie close beneath first antennz, by which slightly exceeded in length both in male and female. Second antennz five-jointed, fourth joint longest or slightly exceeding second, with fifth, third and first following in order named, and last mentioned very short. Each second antenna ended by densely setiferous rudimentary flagellum, considerably longer than that of first antenne and sometimes imperfectly articulated. Mandibles of usual form, curved inward at tip where a pair of horny. 300 REPORT OF NEW JERSEY STATE MUSEUM. U-shaped teeth. First maxilla formed of stout forwardly di- rected column and posteriorly directed palp, with tuft of seven or eight long sete at end, anterior ramus stout and curved toward median line, with group of about eight stout curved spines at tip and each with two series of fine apically directed denticuli. Brush of stiff setze lies near base to side of spines, and small group of spines on one face near tip, and not denticulate or with brown color of those in apical group. Maxillipeds adherent basally by short stout hooks, and basal joints prolonged on anterior or oral aspects into plate-like processes, which coupled together in median line. Each basal joint with flattened palp of four joints, and terminal three with long sete. Somewhat falciform branchial epipod attached to maxilliped at base by means of slender stalks. First gnathopods strongly chelate in both sexes, but especially in males. ‘Thumb terminates by horny tooth, and external to and just within this a sharp-edged tubercle, with tooth of dactylopo- dite biting between the two. Limbs of first free segment of perzon long and slender, terminal claws but slightly curved. Two succeeding pairs stouter, with dactylopodite and claw shorter than in first pair. Last three pairs still stouter, dactylopodite bearing strongly hooked claw with comb-like series of minute curved teeth on each side, and distal end of propodite with row of stout sete. All limbs, except those of first free segment, with distal end of carpopodite crowned with few stout bifid or ser- rulate spines. Only anterior three segments of pleon with pleopods, each consisting of flat basal piece (protopodite) with two one-jointed blades attached, furnished on outer edges with long pinnate sete, exopodite bearing about thirty-five and endo- podite about fifteen. Both protopodite and endopodite bear long stout seta on inner edges. Uropods four-jointed, joints cylindri- cal and increase in length from base to tip. Behind head body width becomes gradually less with each successive segment. Fourth free segment of perzon longest, slightly exceeding third, which in turn longer than fifth. Pleon formed of six distinct seginents, fourth and fifth much shorter than others and sixth terminates behind by blunt median projection. Dorsal surface THE CRUSTACEA OF NEW JERSEY. 301 furnished laterally with few sete, which on first and second seg- ments of pleon form short row on each side, but never form transverse band crossing segment. Marsupia of female thin- walled pouches attached to ventral wall of sixth thoracic seg- ment, increase with the development of the eggs, and in some specimens, extend over fifth to seventh segments, to which not attached, however. Color (in alcohol) pale yellow, mottled with brownish on head, excepting over about thirty elliptical and sub-elliptical areole symmetrically arranged toward middle line. Dorsal sur- faces of chelz similarly marked. Body and limbs behind head much paler, as usually concealed in tubular dwelling. Length 4.7 mm. (H. F. Moore.) Remarks.—This interesting animal is only known from Sea Isle City in this State. It was found by Dr. H. F. Moore, in 1894, living in minute tubes in crevices between the scales of the carapace of the loggerhead turtle (Caretta caretta). Accord- ing to their describer they were seen crawling carefully about among their fellow voyagers or lying at the mouths of their domiciles with only the head and chelz projecting, when undis- turbed, otherwise they promptly retreated out of sight. Order STOMATOPODA. The Mantis Shrimps. Stalked eyes and first pair of antenne borne upon distinct movable segments. Rostrum of adult separated by movable joint from carapace. Latter small, not covering last four dis- tinct thoracic segments. First five of eight pairs of thoracic limbs not biramous, but adapted to serve as accessory mouth- parts, second pair being strongly developed into large raptorial limbs in which, as in three following pairs, terminal segment (dactylus) closes upon next segment (manus) like blade of pen- knife. Last three pairs of thoracic limbs biramous, with lateral appendages upon penultimate segments and adapted for walking. Abdomen very strongly developed. Tufted gills carried on ex- opodites of first five abdominal appendages and sixth pair (uro- 302.

Family CHLORIDELLIDAL. The Mantis Shrimps. Abdomen larger than cephalothorax, gills attached to its under surface, last joint and appendages of joint next, greatly developed. Carapace more or less quadrilateral, with two longi- tudinal grooves above leaving exposed two first head segments and several body segments. Frontal plate mobile, separated from carapace by suture. Internal antennze with three flagella. External antennz short, bearing large oval scale. Second pair of maxillipeds large, prehensile, with inferior edge of last two joints usually armed with spines. ‘Three first pairs of thoracic legs shorter, prehensile, applied to buccal cavity, with last joint but one expanded. Succeeding pairs of thoracic legs slender. Remarkable crustaceans, strongly suggestive of the orthop- terous insects known as the Mantis or Praying Horse. They range through most seas in shallow water, and may be found sometimes in holes, tide-pools and holes in the sand at low tide. The young are said to occur on the surface of the sea.

Upper surface of carapace with median bifurcated ridge longitudinally, and two on each lateral lobe, of which internal short and external ends abruptly before reaching hind rounded end. Lateral ridges produced into large anterior lateral spines and posterior lateral edges angled. Fifth thoracic segment with separate ventral and lateral spines, latter slightly curved forward and acute. Lateral processes on next two segments strongly produced and acute or mucronate. First five abdominal segments with eight distinct carine. Telson with crest and curved line of pits, six marginal spines and eight basal carinze, and on each side three to four sub-median, six to nine intermediate, and one lateral denticle. Swub-median spines of telson with immovable tips. Carinz and elevations at bases of denticles always distinct. Margin of telson or of abdomen never thickened in males. E’yes large, triangular, with oblique corneal axis equal to peduncular axis. Six teeth on dactylus of raptorial claw, and outer edge of dactylus sinuate. Rostrum variable, usually little longer than broad, sub-quadrate or hemiellipsoidal and with lateral and median carine. Color in life horny-brown, and abdominal segments blotched irregularly with dusky. Caudal plates yellowish, edged with blackish. Eyes green. Length 18 cm. Remarks.—The squill ranges along the coast of North Amer- ica from Massachusetts to Florida, and is sometimes met with in large numbers. It is valued as food in some places, and in others as bait, by the fishermen. It ranges from the beach down to twelve fathoms, and burrows in mud near low water, when it is often dragged ashore in hauling seines. Verrill says it is often thrown on the beaches by the waves, and probably usually burrows in the mud below low-water mark, but in certain localities it has been found burrowing at or near low-water mark of spring-tides, forming large irregular holes. THE CRUSTACEA OF NEW: JERSEY. 305 The very curious free-swimming young were taken in towing nets. Large examples are eight to ten inches long and about two broad. By means of the strong raptorial claws the animal can hold its prey securely, and can give a severe wound to the human hand, if handled incautiously. It also uses the stout caudal appendages, which are armed with spines, very effectively. The colors are quite vivid, considering its mud-dwelling habits. The body is generally pale green or yellowish-green, each seg- ment bordered behind with darker green and edged with bright yellow. The tail is tinged with rose and mottled with yellow and blackish. Outer caudal lamelle with base and spines white, last joint yellow margined with black. Inner ones black, pale at base. Eyes bright emerald-green. Inner antenne dark, with yellow band at base of each joint, and flagellum annulated with black and white. I have seen this species several times in New Jersey, as at Cor- son’s Inlet, Stone Harbor, Anglesea and Cape May. During 1911 Mr. Brown secured several at the latter locality, and these are the basis of the above description. During that season the species was abundant about Cape May. It has also been found near Point Pleasant. During May of 1912 several large examples were seined in Chincoteague Inlet at Wallop’s Beach, Virginia, with Crago sep- temspinosus, Callinectes sapidus, Ovalipes ocellatus and Pale- monetes vulgaris. Mr. W. T. Davis tells me has obtained it on two occasions on the south side of Staten Island, N. Y. Order SCHIZOPODA. The Schizopods. Mandibular palp generally exceeds length of mandible itself. Maxillipeds sometimes quite pediform. First pair of legs de- veloped as true gnathopoda, and others uniform, not cheliform or modified as prehensile organs. Exopods strongly developed on all limbs of trunk. Ova invariably placed below trunk and 20 MU 306 REPORT OF NEW JERSEY STATE MUSEUM. usually contained in a pouch or marsupium, formed generally of certain number of lamelliform leaflets issuing from bases of legs. Incubatory lamella sometimes wanting. Young pass within mar- supium of female through one or more so-called pupa states be- fore hatching. Young also sometimes hatched in very im- mature condition, and not attaining, till after very complicated free metamorphosis, characteristic adult form. Four families are admitted, as the Lophogastridz, Eucopiide, Euphausiide, and the single remaining one represented, so far, in our limits. Family MYSIDAE. The Opossum Shrimps. Carapace usually rather small, its hind part only loosely cover- ing trunk, segments of which distinctly defined, though very narrow and crowded together in dorsal part. Maxillipeds strong, exopodite well developed and natatory, epipodite lanceolate and projecting within branchial cavity. First pair of legs modified gnathopoda. Remaining legs uniform and generally rather feeble, terminal part usually subdivided into short setiferous articulations and dactylus usually small or absent. No true branchiz present. Marsupium usually formed of only two or three pairs of incubatory lamellz issuing from bases of hindmost pair of legs. Female caudal limbs quite rudimentary, not formed for swimming. In male caudal limbs either natatory or some modified to serve as copulative organs. Inner plate of uropod generally contains within its base peculiarly developed auditory apparatus. Development without any free metamorphosis. Genera about twenty-eight. Genus MYSIS Latreille. PLATE 90, FIGURE 2. Mysis Latreille, Hist. Nat. Crust., VI, 1803, p. 282.

Carapace becomes very narrow anteriorly ending in short flattened rostrum. Ab- domen slender, tapers, elongate, nearly cylindrical. Eyes large, short, bases hidden below front edge of carapace. First antennz inserted above second pair below eye near median line, and with two terminal flagella to each one. Second anteane longer, basal joint with elongated laminar appendage attached, and its inner edge ciliated. ‘Two succeeding joints of peduncle slender and cylindrical, and flagellum filiform. Foot-jaws of two pairs, entirely pediform. First pair short, formed of three distinct branches. Of latter internal pediform portion five-jointed, hairy and doubled upon itself in front of mouth. Middle branch or palp elongated and formed of numerous articulations. Basilar joint very large, with ciliated strap-shaped process on each side. Third or external branch, or flabelliform appendage, represented by semimembranous scale directed upwards and lying under edge of carapace. Second pair of foot-jaws of similar forma- tion, but without flabelliform appendage. Feet in six pairs, formed of corresponding elements with external pedipalps and five pairs of feet, as in Decapods. Each consists of two branches, decreasing in length from before backwards, and formed for swimming. First four pairs of feet without flabelliform ap- pendage, though last two have it. This part very small in male, though greatly developed in female, and forms on each side broad plate bent under sternum, thus forming pouch in which eggs are first deposited and in which secluded young pass early period of their life. Species rather numerous, though but one recorded from our shores. Mysis americana S. I. Smith. Mysis americana §. I. Smith, Rep. U. S. F. Com., I, 1871-72 (1873), p. 552. Beesley’s Point, New Jersey.

Pl. 7, fig. 20. New York coast. Description.—Anterior edge distinctly rostrated, but only slightly projecting, evenly rounded, and inferior angle project- ing into sharp tooth. Antennules of male with densely ciliated sexual appendage, outer flagellum nearly long as body and inner slightly shorter. Antennal scale about three-fourths long as carapace, about nine times long as broad, tapering regularly from base to very long acute tip and both edges ciliated. Ap- pendages of fourth abdominal segment in male as usual in typical species. Outer ramus slender and naked, its pair of terminal stylets equal in length, slender, curved toward tip, and distal half armed with numerous short sete. Ultimate segment of ramus itself little more than half long as stylets, and penul- timate segment four or five times long as terminal. Inner lamella of appendages of sixth segment about long as telson, narrow, slightly broadened at base, and tapers to slender obtuse point. Outer lamella one and one-half as long as inner, eight times long as broad, slightly tapering, and end subtruncate. Tel- son triangular, broadened at base, lateral edges slightly convex posteriorly, and armed with stout spines alternating with intervals of several smaller ones. Telson tip very narrow, truncate, armed with stout spine each side, and two small ones filling space between their bases. Length 12 mm. (Sid. Suaithy) Remarks.—This species, originally found at Beesley’s Point, ranges northward along the New England coast. Smith men- tions having secured it in April, in pools upon the salt marshes. It has also been found below low water, as among sea-weeds, to a depth of thirty fathoms. It is found among alge and in the stomachs of fishes. Verrill says it occurs in immense numbers among the algze growing on rocks just below low-water mark, especially in spring. It is an important species, as it forms one THE CRUSTACEA OF NEW JERSEY. 309 of the principal kinds of food for shad, spotted flounder and mackerel, besides other fishes. Adult examples are only about an inch in length. ‘The animal is nearly transparent, whitish, with prominent black eyes, and a row of more or less pronounced dark stellate spots along body, both above and below, with similar specks often on tail. Spot of dark-brown or blackish often oc- curs on each side of carapace. ‘The intestine shows through as greenish or brownish line. Order DECAPODA. The Stalk-Eyed Crustacea. Thoracic segments united with head to form cephalothorax usually covered by carapace. Eyes on stalks, movable. Mouth armed with mandibles and jaws for mastication. Third maxilli- peds leg-like. Three anterior pairs of thoracic lines biramous foot-jaws, and posterior five pairs walking-legs without exopo- dites. So-called gills generally present, thoracic. This great group includes the larger and higher forms. ‘Three divisions are here admitted as sub-orders, as the transition be- tween the Macrurans and Brachyurans is gradual and indistinct. Key to the Sub-Orders. a. Abdomen usually shorter than cephalothorax, and commonly held in an extended position; usually distinct rostrum present; eyes not enclosed in orbits; antennules and antenne large; antennules not sunk in pits; an- tennze with an exopodite or squame. b. Abdomen equally or better deveoped than cephalothorax, behind which more of less completely extended and beneath which never per- manently flexed, ends in large symmetrical tail-fan with almost always foliaceous lateral lobes (caudal swimmerets) ; front not joined with epistome; thoracic sternum usually narrow, if broad last seg- ment not independently movable, genital ducts never open on sternum; antennal peduncle commonly with a movable foliaceous exopodite, though not always present.

Abdomen less developed than cephalothorax, exceptionally elongate, symmetrical, extended in straight line behind cephalothorax when either rolled on itself or flexed against sternum or coiled spirally, in 310 REPORT OF NEW JERSEY STATE MUSEUM. last case mostly soft and asymmetrical; sixth abdominal somite sel- dom without appendages homologous with caudal swimmerets; front not united with epistome across ophthalmic somite; last thoracic seg- ment independent, when not atrophied movable; genital ducts never open on sternum; antennal peduncle carries an exopodite, this never foliaceous. ANOMURA aa. Abdomen shorter than cephalothorax, beneath which it folds permanently ; front joined with epistome across hidden ophthalmic somite to form an interantennular septum; eyes enclosed in orbits or tubular cavities of carapace; antennules and antenne small; bases of antennules sunk in pits of carapace; antennze without exopodite; third maxillipeds flattened, valve-like; thoracic sternum usually, not always, broad, last segment fused with others; sixth somite mostly without appendages, when rarely present (Dromide) appearing as pair of small lateral plates intercalated between sixth and seventh somites; genital ducts of female usually, not always, open on sternum, and those of males sometimes also. BRACHYURA Sub-Order MACRURA. The Macrurans. Body elongate, cephalothorax less than half its total length. Front not fused with epistome. Carapace generally produced anteriorly into a rostrum and generally covers ophthalmic somite. Abdomen large and symmetrical, more or less completely ex- tended behind cephalothorax, but never folded beneath it, ends in symmetrical tail-fan with foliaceous lateral lobes (caudal swimmerets). ‘Thoracic sternum generally narrow. Abdominal pleura behind first generally well developed, and terga commonly overlap one another. Eyes seldom lodged in orbits.

Antennal flagellum long. Man- dibular palp large and broadly foliaceus, second joint vastly larger than first. Palp of first maxilla commonly ends in little distinctly articulated flagellum.

Abdominal appendages of moderate length, exopodite longer than endopodite, either foliaceous or slender. In first pair no endopodite present, but in male replaced by a “petasma” or “andricum’” which usually well pleated and some- times convoluted. In second pair endopodite in male carries little fleshy scale at its base. No podobranchiz present on any legs. Pleurobranchiz present on all, or all but last one or two of last seven thoracic somites. Alcock restricts or indicates Peneus caramote Risso as the type of Penzus, 1 but this action is invalid as the only species included in the original account by Fabricius are: monodon, monoceros and planicornis.. If no other action has been made the first species (monodon) may be considered the type, as suggested by Steb- bing. Peneus longirostris Lucas may be identical with Peneus membranaceus Heller, and therefore Alcock’s designation of the latter as the type of Parapeneus is valid. Unless Peneus kroyeri Heller is identical with Xiphopeneus haritii S. I. Smith, Alcock’s designation is useless, as in any case Xiphopeneus is monotypic. Key to the Species. a.

Abdominal keel on fourth, fifth and sixth segments sharp, and groove either side of latter. High median keel reaches almost to hind edge of carapace, and with deep broad groove either side extending parallel, also nearly reaching hind edge of carapace. Posterior half of keel with groove forming into double ridge. Front half of keel arched, highest above orbit, with nine teeth, of which six on rostrum and last nearly half way back on carapace. Ophthalmopod moderate. Antennules with short stout hairy peduncles, which extend for- ward far as, or slightly beyond, rostrum tip, and biramousslender flagella equal or longer than peduncle. Antennz with very long slender filamentous flagella, these often longer than body. Ros- trum unarmed, becoming horizontal towards end, and two or three denticles on lower edge. Antennal spine, hepatic spine, carina and groove all well defined. Hepatic spine with partly horizontal suture below. Cervical suture extends only half way from hepatic spine to dorsal keel. Outer joint of mandibular palp much larger than inner, very broad and not extended as narrow tip. First maxilla with long endognath and also well segmented. First maxilliped with slender four-segmented endopod, and lamellar unsegmented exopod. First and second gnathopods with well-developed epipods, and exopods large.

Telson with deep median 316 REPORT OF NEW JERSEY STATE MUSEUM. groove and a pointed end. Color more or less translucent, be- coming brownish in alcohol. Length 160 mm. Remarks.—A species of wide distribution along our Atlantic Coast, ranging from Cape Cod southward to Florida and Brazil. It is also said to occur on the Pacific Coast. ‘The bathymetrical range is nine hundred and fifty-five fathoms. It is, however, rather occasional on our coast, and though a few have been re- ported, it is apparently not common or regular. Stimpson found it in fresh water at Beesley’s Point. Along the southern shores of the United States it is more or less common, though less fre- quent than the usually larger Peneus setiferus, with which it as- sociates and is also exposed for sale in the markets. As these ani- mals soon die after being removed from the water they cannot be transported any great distance in a fresh condition. I have no New Jersey material at hand. Penzeus setiferus (Linnzeus).

Remarks.—This southern species occurs occasionally as far north as the shores of our State at least, though it does not seem to have been recorded north of Norfolk, in Virginia, before. It occurs associated with the preceding species, and is doubtless confused by such observers. as casually notice large prawns. Southward it ranges to Florida and the Gulf of Mexico. I know of two large New Jersey examples, one secured at Holly Beach in August of 1893 by Mr. N. H. Boon, and another taken at Atlantic City in 1901, and obtained from Mr. C. Buvinger. 318 REPORT OF NEW JERSEY STATE MUSEUM. Possibly other examples reported to me on reliable authority are likely this species. They were noted at Peck’s Bay, along Dela- ware Bay at various points, at Fishing Creek and Green Creek, Sea Isle City, Stone Harbor and Anglesea. ‘hey appear to be noticed mostly in the bays and sometimes in brackish or nearly fresh water. As food they are of value, though their scarcity usually precludes any local supply. Mr. D. McCadden secured it at Ocean City on July 6th, 1913. Super-Family CARIDEA.

Remarks.—A species of mostly northern distribution on both coasts of North America. It ranges from Alaska to California on the Pacific Coast and southward on the Atlantic Coast to the Middle States region. It lives on sandy bottoms and ranges to a depth of sixty or severity fathoms. Verrill says it occurs in great numbers on the sandy flats and in tide-pools and rivulets, as well as on sandy bottoms in deeper . water off shore. It is more or less specked irregularly with gray, and imitates the color of the sand very closely. When resting quietly on the bottom, or when buried partially and sometimes almost entirely, except the eyes and long slender antennze it can- not easily be distinguished by its enemies, and therefore gains great protection by its colors. When left by the tide it buries itself to a considerable depth in moist sand. It needs all its powers for concealment, however, for it is eagerly hunted and captured by nearly all the larger fishes which frequent the same waters, and it constitutes the principal food of many of them, such as the weak fish, king fish, blue fish, flounders, striped bass, etc. Fortunately it is a very prolific species, and is abundant along the entire coast. The young swim free for a considerable time after hatching. Many examples collected from various localities, as Corson’s Inlet (March, 1909), Ocean City (June, 1911), Goshen Creek (October, 1911). Besides these are many examples which were examined in the field, such as at Point Pleasant, Stone Harbor, Sea Isle City, Anglesea, Fishing Creek, Green Creek, Dias Creek, Cape May and Atlantic City. Several examples were taken from the alimentary canal of a smelt (Osmerus eperlanus) received from the Philadelphia mar- kets and said to have been taken in the Raritan River in 1910. This species was very abundant at Watchapreague in the inlet, Virginia, in May of IogIt. It was abundant at Manasquan July 19th, 1910, associated with Palemonetes vulgaris, Ucca pugilator, Callinectes sapidus, Anguilla chrisypa, Fundulus heteroclitus macrolepidotus, THE CRUSTACEA OF NEW JERSEY. 323 Cyprinodon variegatus, Lucama parva, and Memdia menidia notata. Mr. W. B. Davis and the writer found it abundant at Great Bay, in ditches, and along the shores, often in vegetation. It was less common than Palemonetes vulgaris, with which asso- ciated, besides Anguilla chrisypa, Fundulus heteroclitus macrole- pidotus, Fundulus lucie, Tylosurus marinus, Apeltes quadracus, Syngnathus fuscus, Menidia menidia notata, Pomatomus salta- trix, Centropristis striatus, Tautoga onitis, Opsanus tau and Pseudopleuronectes americanus.

Off Montauk Point, Long Island. Description.—Cepalothorax moderate. Ophthalmopod rather short, and depression in which it rests moderate or shallow. Eye moderate, though little more bulky than peduncle, latter becoming considerably small or constricted at base. First antennz bi- ramous, ends in two long multiarticulate filaments, subequal and long as rostrum. Flagellum of first antenne more robust than filaments, multiarticulate, but only projecting slightly beyond rostral tip. First antennze with basal portion as broad scale, though less in width and length than that of second antenne. Second antennz longer than rest of body, multiarticulate, fila- mentous, with broad lobate scale above extending forward beyond rostral tip. Rostrum compressed, completely separating ophthal- mopods, prominent, ends in long sharp-pointed spine in front, upper edge entirely antrorsely serrate and lower anterior edge 326 REPORT OF NEW JERSEY STATE MUSEUM. similar. Lower posterior rostral edge entire. Mandible mod- erate, strong. Mouth moderate. First maxille small, short, broad, without exopodite. Second maxille similar, a little larger than first, with well developed exopodite. Pereion nearly cylin- drical, short. First maxillipeds short, compressed, with terminal joint as rather broad compressed lamina folding over to com- pletely obscure maxille. T’wo exopodites to each of first maxil- lipeds. Second maxillipeds pediform, long, slender, each with long slender exopodite. All exopodites on maxillz and maxilli- peds similarly tapering into flexuous filamentous ends. First pereeopods not enlarged, slender, pediform, chelate, though little less developed than second pair. Latter a little longer, though not conspicuously enlarged, also chelate and pediform. Third, fourth and fifth perzeopods subequal, similar to one another, slender, with simple dactyli. Pleon capable of curving evenly, with second and third shields largest, though sixth about equally long and narrowly constricted. Five pairs of pleopods, com- pressed, and each ending as two subequal flagella. Telson slender, acuminate, ending in several short bristles. External elements of rhipidura each side as two similarly broad expanded flagella, outer little longer, retractile to fold in vertical axis of body. Color in life pale brownish, mostly glassy or transparent in appearance. In alcohol or other preservatives they turn pink or reddish. Length 45 mm. Remarks.—The prawn ranges all along the coast of North America, southward to Florida at least. It frequents muddy shores and brackish water. It is also abundant in the eel-grass, and is preéminently an inhabitant of weedy estuaries. Though living along the coast on sandy shores it also ranges well up the coastal rivers into fresh water. It seems to be most abundant in the eel-grass, occurring sometimes in myriads. In small ditches and ponds it is often very abundant. Its value lies chiefly in its affording an abundant food supply to most larger fishes. On April 30th, 1904, it was found abundant in the ditches of Cold Spring Inlet, in Cape May County, associated with Fundu- lus majalis, F. heteroclitus macrolepidotus, F. diaphanus and Menidia menidia notata. THE CRUSTACEA OF NEW JERSEY. 327 On June 18th, 1904, it was common at Grassy Sound, in Cape May County, and was found associated with Fundulus hetero- clitus macrolepidotus, Lucqiia parva, Cyprinodon variegatus and Menidia menidia notata. It was taken in great numbers by the fishermen, who were all fishing about the wharf with it as bait. I saw numbers of Centropristis striatus and Tauwtogolabrus adspersus angled with it. On December 31st, 1905, a number were found in Cedar Swamp Creek at Petersburg Bridge, in Cape May County, asso- ciated with Anguilla chrisypa, Abramis crysoleucas, Esox reticu- latus, Fundulus heteroclitus macrolepidotus, F. diaphanus, Apeltes quadracus and Eupomotis gibbosus. Though the next day, January Ist, 1906, we found it rare above this point or at the forks, only an occasional example being taken with the num- bers of small fish, such as Umbra pygmea, Aphredoderus say- anus, Acantharchus pomotis, Mesogonistius chetodon and En- neacanthus obesus. On October 6th, 1907, it was very common in New England Creek, in Cape May County, associated with Anguilla chrisypa, Fundulus heteroclitus macrolepidotus, F. diaphanus, Lucania parva, Cyprinodon variegatus, Gambusia gracilis, Menidia beryllina cerea, Menidia menidia notata and Eupomotis gibbosus. On July 28th, 1909, a number were found associated with Fundulus majalis, F. lucie and Cyprinodon variegatus, in a stall inlet tributary to Barnegat Bay below Seaside Park, in Ocean County. On October 24th, 1909, it was very numerous in Coxe’s Hall Creek, in Cape May County, associated with Fundulus hetero- clitus macrolepidotus and Gambusia gracilis. On November 2d, 1909, it was very abundant in the fresh waters of Muddy Creek, one of the headwaters of the Maurice River at Elmer, in Cumberland County... The associated animal life consisted of Anodonta cataracte, Spherium (Musculium) partumenium, Physa_ heterostropha, Campeloma decisum, Abramis crysoleucas, Notropis chalybeus, Schilbeodes gyrinus, Esox reticulatus, Mesogonistius chetodon and Eupomotis gib- bosus. 328 REPORT OF NEW JERSEY STATE MUSEUM. On April 3d, 1910, many were found in the salt ponds at Corson’s Inlet, in Cape May County, associated with Fundulus heteroclitus macrolepidotus, F. lucie, Cyprinodon variegatus and Gasterosteus aculeatus. On October 13th, 1911, in Bidwell’s Channel, an artificial out- let from Delaware Bay cut into Goshen Creek, we examined multitudes of this prawn, gathered by Mr. Edward Howell. The animals captured and mixed with them were Callinectes sapidus, Anguilla chrisypa, Fundulus majalis, F. heteroclitus macrolepidotus, Cyprinodon variegatus, Menidia beryllina cerea, M. menidia notata, Bairdiella chrysura, Leiostomus xvanthurus, Micropogon undulatus and Pogomias cronus. On April 5th, 1912, this species was found very abundant in small ditches tributary to Dennis Creek, at South Dennis, in Cape May County, associated with Fundulus heteroclitus macro- lepidotus, Fundulus lucie and Anguilla chrisypa. On July 4th, 1912, Mr. B. Long secured it, with Apeltes quadracus, at Spray Beach, in Ocean County. Mr. W. B. Davis found it common in a mud-pool near the mouth of Cedar Creek, tributary of Barnegat Bay, on October sth, 1912, with Fundulus heteroclitus macrolepidotus, Lucama parva and Cyprinodon variegatus. Examples before me from Corson’s Inlet, Elmer, Point Pleas- ant, Manasquan Inlet, Coxe’s Hall Creek and Peck’s Bay. The prawn is also very abundant in our neighboring States. In Delaware I secured it in multitudes at Rehoboth, Millsboro, Milford, Laurel, Marydel and Delaware City. In Maryland it was found in small numbers at Fishing Creek near Elk Neck in Cecil County. In Virginia it was very abundant at Parmores Island, and in Locustville Branch, in May of t911. Mr. W. T. Davis has also found it on Staten Island, N. Y. Palzemonetes carolinus Stimpson.

Rostrum ciliated and serrated above throughout to tip, with nine teeth, and posterior tooth little further re- moved from second than second from third, and placed at front third of carapace. Third rostral tooth directly above base of eye-peduncles. End of rostrum acute of sometimes minutely bifid. Beneath, rostrum armed with four teeth, and densely ciliated. Both pairs of antennze as in Palemonetes vulgaris. Feet of second pair long, reach well beyond end of rostrum. End of carpus falls just short of end of antennal scale. Hand much stouter than in Palemonetes vulgaris, and fingers a little shorter than palm. First pair of feet reach scarcely beyond end of carpus of second pair. (Stimpson. ) Remarks.—Known in our limits from Stimpson’s record for Great Egg Harbor, where it was secured by Prof. S. F. Baird. Stimpson says it is of the same size and nearly allied with Palemonetes vulgaris, but easily distinguished by its recurved rostrum, and larger second pair of feet. Stimpson had it with a range from this State southward to South Carolina, and in depths from two to seven fathoms. Famly HIPPOLYTIDA:. Rostrum of important size. Eyes not covered by carapace.

It was found abundantly at Somers Point in the summer of 1864, and according to its describer it lives among Zostera just below low-water mark. It was also obtained by Stimpson in the har- bor of Norfolk, Virginia, in June, 1853. Tribe ASTACIDES. Body not compressed, sometimes depressed.

Type Astacus marinus Fabricius, first species. (Virtually designated [as Cancer gammarus Linneus] by M. J. Rathbun, Proc. Biol. Soc. Wash., XVII, 1904, p. 170.) Carapace nearly cylindrical, and rostrum: armed on each side with three or four teeth. Thorax with last joint immovably connected with preceding one. Abdomen nearly cyclindrical, segments ending laterally in large flattened triangular process. Terminal abdominal segment with tooth on each side near end. Telson with outer lamina divided transversely, about a third from end, with distinct movable joint. External antenne sit- uated above and to outer side of internal pair, scale dentiform, dilated on inner side and scarcely covers penultimate joint of peduncle. Internal antenne with peduncle nearly long as that of external. Eyes subglobose, not broader than foot-stalks. External foot-jaws pediform, reach forwards beyond peduncles of antenne. Anterior legs very robust, unequal, larger with fingers strongly tuberculated on grasping edge and smaller merely toothed. Second and third pairs of legs didactyle, and fourth and fifth pairs monodactyle. Species three, and the single form known from our shores very large, prolific, and greatly valued as food. The generic name of this animal has been the subject of much controversy. Homarus is accepted here in accord with pre- vailing opinion, and the name Astacus is allowed for the craw- fishes. Astacus dates from Gronow in 1764, 1f polynomia- lists are accepted, or from Fabricius in 1792, if binomialists only are used. In any case Cancer astacus Linnzus is the type according to the law of tautonomy. According to Faxon, in 1898, its first designation with a type species was by Latreille, in 1810. Ortmann claims a prior designation, with different results, though his suggestions would be invalid if considered from the point of view of tautonomy. Homarus is used as a nomen nudum by Fabricius in 1796, in the index to his supple- ment. 334 REPORT OF NEW JERSEY STATE MUSEUM. Homarus americanus Milne-Edwards. PLATES 96 TO QO. Lobster.

Description.—Body thick, with carapace not quite twice as long as broad. Carapace rather compressed at sides, and surface more or less punctate. Gastric regions separated from posterior regions by groove or furrow. Rostrum narrowly pointed, reaches forward trifle beyond peduncle of external antennz, and upper edge with several denticulations on each side. Antennules THE CRUSTACEA OF NEW JERSEY. 335 with short peduncle, not extending forward far as that of:ex- ternal antennz, and with two subequal flagellze not quite equal to one and one-half rostral lengths, if latter measured from hind edge of orbital socket. External antenne with peduncle almost cylindrical, and very long flagellum depressible back very slightly beyond end of telson. Eyes rounded, their diameter less than that of stalk. Abdomen partly cylindrical, segments smooth, and terminate on each side in strong triangular flat plate. ‘T'ail quite broad, outer plates well divided about outer fourth, and two strong denticles at common base of two outer lamina. Anterior legs greathy enlarged, unequal in size and dissimilar in shape, much larger than other legs. Very strong tubercles on chelipeds of first legs along inner edge, also several on carpus. Other legs weak, second and third pairs weakly chelate and fourth and fifth pairs with simple dactyls. Color very variable. R. Rathbun says it is generally yellow or yellowish-red, with spots or mottlings of green, rarely blue. Mottlings most numerous and dense dorsally, while sides and lower surfaces of claws with yellow predominating. Along lower edge of carapace each side broad band of blue or bluish also extends short distance up hind edge of carapace. Just above this band yellow begins, where uniform or immediately varie- gated with dark blotches. Green color often replaced by blue shades. Sometimes entire carapace reddish. Rostrum olive- green, its spines deep rich red. Abdomen with markings cor- responding to carapace. Distinct line down back of carapace usually dark green. ‘Tail-flaps edged posteriorly by dark olive- brown band. Upper surface of anterior large claws reddish or orange shade, deeper towards ends where very bright red, fading whitish at tips. Over this general color outer edge of claw with broad dark olive-brown or black banding, and numerous large spots of same color cover more or less of remaining surface. Under surface of these claws mostly always of variable orange tints, terminal joints more intense than inner ones, which more or less marked with green or blue. Other legs much lighter below than large claws, with green or blue markings, especially above and at ends of joints. Tips end in deep orange-red, while 336 REPORT OF NEW JERSEY STATE MUSEUM. ornate bunches of hairs like on other parts of body almost ruby- red. Soft skin covering under surface of abdomen and swim- merets faint pink. Length four feet, with an average length of about 375 mm. Remarks.—The lobster is distributed along the Atlantic shores of North America from Labrador to Delaware, and ranges in depths of from less than one to more than one hundred fathoms. It is most abundant and reaches its maximum size within the northern part of its range, or from Maine northward. De Kay says that lobsters were taken in comparative small numbers along the New Jersey coast, though two years after the Dela- ware breakwater was built in Delaware Bay, lobsters made their appearance there in great quantities. R. Rathbun says this point may be considered the southern boundary of the species, though several records are known from the region to the south. Of these, lobsters are said to have been seen along the beach in the surf near Indian River Inlet in Delaware, and two or three have been recorded at Johnstown in the northeastern corner of Virginia. Several have also been captured in North Carolina. The depth of water which these animals inhabit is variable, according to the season and the temperature of the water. They sometimes occur in shallow water close in shore, and again are stranded on the beach, sometimes in large numbers, after heavy storms at sea. Herrick’s summary of his extensive observations gives the following information: The great diversity of the character of environment explains in some measure the numerous variations in the habits of the lobster, as time and frequency in moulting, egg-laying, hatching the young and rate of growth. It displays a considerable degree of intelligence and has organs to which the various senses of the higher animals have been ascribed. The tactile sense is diffused over the whole body. It has the sense of smell and of taste, though the so-called auditory are doubtfully really ears. The sea bottom is its natural habitat when adult, and it never leaves this location or the water unless obliged. No coastwise migra- tions are known, but numbers of lobsters move to and from deep THE CRUSTACEA: OF NEW JERSEY. Rar water during the fall and spring, these movements varying with the coast and nature of the bottom and influenced by oceanic temperatures, abundance of food, and to some extent by moult- ing and breeding habits. Lobsters often stay in relatively shallow and cold waters of harbors through the winter, but then they are only found on rocky bottoms, where food is most abundant. They seem to prefer a temperature of about 50°. In severe winters they are either driven into deep water, or if living in harbors seek protection by burrowing in the mud. In such cases a prolonged cold spell may prove fatal. When adult the lobster is essentially nocturnal, though in the larval state the reverse is true. ‘he lobster is a great burrower, making holes with the large claws and tail-fan, sometimes two or three feet in length. These burrows are never used when moult- ing, and are solely for protection. ‘The burrows are almost always entered by the lobster tail first. The adult lobster feeds chiefly on fish, dead or alive, and also invertebrates. It also takes a small quantity of vegetable food, such as alge and eel-grass. Fragments of dead shells, coarse sand and small gravelstones are also swallowed. ‘The former yield lime, which is absorbed and finally laid down in the skeleton. Many small fish living on the bottom fall a pray to the sharp cutting claw of the lobster, which it uses with great skill and dispatch. The larger lobsters prey in- variably upon the smaller and weaker ones they may find. The food is seized, torn and crushed by the large claws, and is then taken up by the appendages about the mouth (maxillipeds, maxillze and mandibles), by which it is successively torn and chopped fine, when this is possible. While the animal is eating a stream of fine particles is passed into the mouth, thence to the gastric mill or masticatory stomach. Here the food is ground and the fluid or digestible parts are strained into the small delicate intestine from which they are absorbed. ‘The indigestible refuse is re- gurgitated from the stomach bag. In copulation the female receives the sperm of the male in packets or spermatophores, which are deposited in an external chamber (the seminal receptacle). This is a blue heart-shaped structure, placed on the lower side of body between bases of 22 MU 338 REPORT OF NEW JERSEY STATE MUSEUM. the fourth pair of legs. Males do not discriminate the sexual condition of the female, which may be impregnated any time. Probably copulation takes place usually in the spring. Most females lay eggs in July and August, though eggs are also laid in lesser degree at other times. The females carry the eggs from ten to eleven months. Summer spawn- ing lasts.about six weeks.

Cyclops. I am greatly indebted to Mr. R. A. Spaeth for the opportunity of examining his MSS., and here recording the species of this variable and difficult genus. Mr. Spaeth spent several years in studying the species in the vicinity of Haverford, Pennsylvania. His researches are incorporated in an excellent and elaborate MS. memoir, well illustrated by his own hand. In view of the absence of any work on the Pennsylvania species it is hoped he will allow it to pass through the press at an early date. The arrangement of the species is thus in accordance with Mr. Spaeth’s list, though several forms he has not found, which have been recorded elsewhere within the limits of the Middle Atlantic States, are placed provisionally under the various subgenera. The precise locality where Mr. Spaeth’s material was obtained is a single small pond on the estate of Mr. McFadden, directly on the south side of the Philadelphia and Western Railroad tracks and to the right of the bridge that crosses these tracks at “Haverford” station.
