A delicate, semitransparent, small shell, beautifully diversified in markings, spotted with white, scarcely exceeding one fourth of an inch in length. Abundant on the sandy shores of the vicinity, especially near Orne's Point, North Salern, and contiguous to the Marine Rail- way, South Salem. Journ. Acad. Nat. Sc.

Latin, pleasant, delightful, (signifi- cant of its beauty.) SYN. PATELLOIDEA. Gaimard. A larger, thicker and more showy species than the preceding, and not so common. Within, variously marked with brown and white, sometimes with a deep margin of pure white. Obtained by searching at low tide among the rocks, to which it will be found closely adhering. Lynn beaches and other rocky shores on the coast of New England. Described by Say, in Journ. Acad. Nat. Sc., Phil., vol. ii., p. 223. Cabinet of the Society. CREPIDULA. Latin, a little slipper. FORNICATA. Latin, an arch. Arched or convex Crepidula. A Genus nearly related to Patella, yet quite distinct. Adhe- rent to various marine substances, this shell seldom quits its res- idence ; a striking similarity in habits to the preceeding. The present species bears no unapt resemblance to a boat, with a small half deck ; being more convex than most others. Shells found in Essex County. 65 Bf3autiful varieties may be obtained by careful search. Those thrown upon our beaches present little interest, being bleached in the sun. A favorable locality is on the flats and rocks, near Beverly bridge. The fibres and sometimes the entire leaves, (fronds) of spe- cies of sea weed (Algae) are often seen upon these shells. The Laminaria or kelp is not an unfrequent companion. This being produced from its seed-like bodies upon the shells, and growing in a calm sea throughout the summer months, is of no probable disadvantage ; but no sooner do the autumnal storms commence, than the little shell fish is ungenerously torn from its situation, by the agitation of its unwieldy parasitic neighbor, to be cast upon the shore. Rolled pebbles of a large size are also lifted from the bottom, by the simple and perfectly natural agency of this marine vegetable. Common on the beaches of Essex Co.

Latin, flat. .0 Flat slipper Shell A very pretty, pearly vitreous species ; about an inch in length ; found sometimes perfect, but more commonly much worn. Diaphragm or deck occupying half the length of the shell. Shell generally flat, but sometimes tortuous or reflexed, according as it has resided on a plane or curved substance. Lynn beaches, rare.

River Jlncylus. Shell very small, exceedingly thin and yellowish, sometimes white within when old and dead ; resembling a minute Patella. Found under the leaves of the Yellow Water Lily, (Nuphar advena L.) in ditches, ponds, and sluggish streams. Journ. Acad. Nat. Sc. Phil., vol i., p. 125. My Cabinet. 66 Russell's Familiar Notice of some of Ike VELUTINA. Blainville. SYN. GALERICULUM. Brown. RUPICOLA. Latin, living on rocks. Rock Velutina. A very delicate shell, first discovered by Dr. Charles Picker- ing, (formerly of this city,) on the shores of this vicinity, affixed to rocks. Fragile, almost transparent, covered with a brown epidermis ; aperture very large, left side slightly reflexed into an apparent ootumella : whorls, two first small, body whorl large. Is not this Oxynoe glabra; Couthouyl Of four specimens in my possession, no two are exactly similar. One is covered with the epidermis, and was taken from an haddock's stomach, from 15 fathoms ^of water. The three others collected at Phillips' beach by J. True, though evidently the same species, yet vary in them- selves. The smallest, a little more than 0.02 inch long, has no perceptible reflexion, is covered with an epidermis, and has a dozeji or more raised longitudinal striae, which by comparison with the next specimen, seem confined to the epidermis ; its margin more reflexed; the last smooth, with minute striae, light rose color. This gradation in the form of the left margin would seem to agree with Blainville's description of Velutina, which although " Sans collumelle," yet presents, ('ledroit se reunis- sant au gauche, par un depot calcaire, lamelleux." These shells are worthy of being searched for, and would con- stitute no mean addition to any collection. A very fine speci- men of extra size is in possession of Wm. Oakes, gathered by him on Ipswich beach. Described and figured in Journ. Acad. Nat. Sc. Phil., vol vi., p. 266, pi. xi., figs. 17, 18, by T. A. Conrad.

The Marine Shells only, of the order TRACHELIPODA, are de- scribed, as follows. Shells found in Essex County. 67 NATICA. Referring to its cockle or boat shape, HEROS. Say. Latin, large. Saifs large Natica. A familiar and well known shell, sometimes called { 'cockle," and abundant on the muddy shores of our estuaries, and not uncom- mon on the beaches among kelp. Very little can be said in favor of its appearance, being of a dirty bluish color exteriorly, and within of a brownish hue, furnished with a large horny oper- culum. Sometimes of great size. Burrows, under the mud throwing it up, into little prominent heaps. One of those Mol- lusca, which bore other shell fish to extract their food. Journ. Acad. Nat. Sc. Phil., vol. ii., p. 243. Society's Cabinet. NATICA. TRISERIATA. Latin. Three banded. Three zoned Natica. A smaller and very pretty species, with three more or less dis- tinct interrupted bands of dark brown ; found near the City Mills, among the Zostera, and on the shores oi the basin. Also upon the beaches of the vicinity. Cabinet of the Society. NATICA CONSOLIDATA. Couthouy. Thickened Natica. A new species, native and abundant in this vicinity, but only taken from fish in deep water ; it has been hitherto overlooked. About the size of the proceeding, more solid, of a dingy white ; umbilicus nearly closed by the callus. Seems to be a common and favorite food of the haddock. Many specimens were col- lected for the Society by Dr. William P, Richardson, during the summer of 1838. Boston Journ. Nat. Hist., vol. ii., p. 89, pi. iii, fig. 14.

Shell thin, delicate, of a dingy brown, almost egg-shaped, aperture long, narrow, two prominent teeth on the labium ; 68 Russell's Familiar Notice of some of the sometimes prettily banded. Common on salt marshes, and may be found crawling up the stems of grass. Also washed on shore with Patella alveus, on the sands of Orne's Point, North Salem. Journ. Acad Nat, Sc.

Latin, cracked, or having a hole, Shell resembling Turbo or Paludina, having a spire of five whorls, sutures impressed. Columella deeply furrowed, with a profound umbilicus. Found on the beaches of Essex Co. — Described and figured in Journ. Acad. Nat. Sc., vol. vi., p. 266, pi. xi., fig. 19. Cabinet of the Society, NASSA. Latin, Nassa, a bow Net ? OBSOLETA. Say. No obvious signification. Whoever has observed the muddy bottoms of our docks and shores at low tide, must have noticed innumerable black shells, slowly crawling, or stationary. These individuals, thus humble in their localities, and devoid of elegance in their habits, consti- tute the species before us. On nearer inspection and better acquaintance they present a tolerable aspect, not wholly wanting in beauty. The aperture is of a deep blue purple, and beneath, the epidermis is a lighter blue tint. Numerous cancellate spots cover the spires. A species so familiar needs but a passing notice. Described by Say, in Journ. Acad. Nat. Sc. Phil., vol. ii., p. 232. Society's Cabinet. NASSA TRIVITTATA. Latin, three fillets. Three banded Nassa. A much prettier species which I have found only in a dead condition, upon our sandy beaches. Pale yellow or white, gran- ulated, with three reddish bands. Lynn and Nahant beaches — common. Journ. Acad. Nat. Sc. Phil., vol. ii., p. 231. Cabinet of the Society. Shells found in Essex County. 69 TRICHOPTERIS. Sowerby. Greek, triche ; hair, bristle. COSTELLATUS. Latin, ribbed. Shell ovate, whorls six ; lowest larger and longer, having five or six prominent ribs, with alternate strite, (markings.) Interior brownish. Epidermis, yellowish white : occasionally hairs or bristles occur at the edge of each successive growth, giving the shell a hairy appearance, and suggesting its generic name Might be mistaken for Purpura, but very distinct.

BUCCINUM LAPILLUS. L. The most common white cockle upon the rocky shores of our coast, frequently used by marine anglers for bait, in catching sea perch, (Crenilabrus bergall) varies in color from pure white to brown, yellow and reddish, sometimes black — banded, often beautiful. 70 Russell's Familiar Notice of some of the This little shell furnishes the identical color rendered so fa- mous as the Tyrian dye. Linen, accidentally spotted by it, has retained its indelible impression unchanged by any application to remove it. Equally common on the English coast as on ours. See Drummond's Letters to a Young Naturalist, p. 233. Cabinet of the Society. PURPURA IMBRICATA. Lam. Latin, imbricate or scaly. An evident variety of the preceding, and found in all stages of asperity or smoothness, in still waters, and even on our wave beaten coast. The imbricate or scale like processes upon the whorls, give them a curious and pleasing appearance. Among Ulva and Zostera (sea weeds) near the City Mills. Cabinet of the Society. Fusus. Latin, a spindle, (alluding to their usual form.) DECEMCOSTATUS. Say. Latin, having ten ribs. Ten ribbed Fusus. Fragments only, of this fine native shell are usually found upon our beaches ; and occasionally a perfect specimen, but bleached and dead. Very beautiful and perfect specimens I have received from Dr, Ray, of Eastport, Me., where it occurs in native locality. Shell two and a half inches long ; whorls five or six, with ten very prominent transverse ribs on the body ivhorl, a character which readily distinguishes the species : minuter transverse and longitudinal striae between the ribs. Aperture about half the entire length. Interior pure white, with brown markings on the lip, (sometimes grooved) corresponding with the ribs. Epider- mis cinereous. Lynn beaches. My Cabinet — Cabinet of the Society. Fusus CORNEUS. Say, Latin, horn like. Horn colored Fusus. Another fine species, usually found in more perfection than the preceding. Shell more elongated ; volutions seven or eight, sutures profound. Perceptibly striated transversely, covered with a light green epidermis 'which when perfect gives a fine aspect to the shell. Beak much produced. Aperture more than half the entire length ; pure white within.

Notice of Vesperlilio Pruinosus. 77 Gray in Jardine's Magazine of Zoology and Botany, vol ii., p. 498, classes the present species in his Tribe iii. and Genus Scotophilus of Leach. This beautiful and somewhat uncommon species of our Amer- ican Mammalia, has been discovered as resident in this vicinity. Three specimens have been presented to the Society's collection. The first was captured September 14th, 1838, while hanging from a grape vine contiguous to the residence of Mr. Nath. Pope, (near the crossings of the Andover and Newburyport turnpikes) Danvers. Its dimensions were as follows. Extent of wings 16 inches. Length from vent to mouth 3 inches. Total length from tip of nose to extremity of caudal membrane 5 1-2 inches. Breadth of forehead between the ears three fourths of an inch. The second specimen was captured by the sons of Mr. John Preston, about a mile north of the Village meeting house, Dan- vers, on the first of October, 1838 ; confined in the Society's rooms, it survived several days. The third was taken on the 22d of November, 1838, by Mr. Rums Tapley, Danvers, near the last mentioned place. Say, in Long's Expedition to the Rocky Mountains, has given the first description of this species of Bat ; and we are indebted to him for nearly all that has been written on its habits and char- acteristic marks. He mentions it as being common in the vicin- ity of Engineer Cantonment, where the expedition wintered ; also of its being observed near Council Bluffs, by Mr. Nuttall ; and that the late Professor Bartdn, presented a specimen of this bat, that had been captured in Philadelphia, to the Philadelphia Museum. It is probably common in ,the Western States, but with us it must be considered as remarkable and rare. About thirty years since, a specimen was observed by .Mr. Abel Nichols, of Danvers, in this vicinity. The present species may be considered an important addition to the Natural History of Essex County, and, in this point of view, I trust, it will prove interesting. A SKETCH OF THE GEOLOGY AND MINERALOGY OP THE SOUTH- ERN PART OF ESSEX COUNTY, IN MASSACHUSETTS. COMMUNI- CATED TO THE ESSEX COUNTY NATURAL HISTORY SOCIETY, APRIL 24, 1839. BY WM. PRESCOTT. THE following sketch embraces the city of Salem and the towns of Beverly, Danvers, Marblehead, Lynn, Nahant,* Sau- gus and Lynnfield. The principal rocks, areSienite, Greenstone, Porphyry, Silicious Breccia arid Brecciated Porphyry, Chlorite Slate, Argillaceous Slate, Silicious Slate, Magnesian or Verd d'Antique Marble, and Varioloid Wacke. Sienite and Green- stone are by far the most abundant rocks. GRANITE. No bed or deposit of granite occurs in this section of Essex County. A few scattering bowlders only are found in Lynn and Saugus, which increase in size and frequency as you proceed north, through Danvers and Lynnfield, towards the beds of Granite in Boxford. These bowlders of granite are of a very dark color from the black mica which they contain, and in the north part of Danvers, frequently occur several feet in diameter. Bowlders and masses of a light colored granite are frequently seen cast upon the shore, on the east side of Nahant, and on Lynn beaches. GNEISS. The rocks at the north west part of Danvers are more or less stratified, evidently the termination of the Gneiss and Mica slate formations. This structure may be seen as far as Newburyport turnpike, and occurs rarely south east of that road. * Notwithstanding Nahant constitutes a part of the town of Lynn, yet, isolated, as it is, from the main land, stretching several miles into Massachusetts Bay ; and being in many respects peculiar in its geological features, it will in the following sketch, be made a locality for distinct reference. For particular localities, the reader is referred to Lewis' map of Lynn and Saugus. of the, Southern part of Essex County. 79 ARGILLACEOUS SLATE, Occurs at the south east extremity of the promontory of Na- hant, associated with flinty slate and argillaceous limestone. Its color is black, ash color, and occasionally striped with green and gray. SlENITE. An extensive bed of sienite extends in a north east and south- west direction across the south part of Danvers, the south part of Lynnfield, the north part of Lynn, and the north part of Saugus to the town of Chelsea, This range is bounded by Tap- ley's brook on the south east, and by Proctor's brook on the north ; and is from one to three miles in width, forming in many places, high hills of solid rock, and craggy cliffs. Bowlders of sienite from this locality are easily distinguished from those orig- inating from any other. No bowlders of this sienite are to be found to the north of Proctor's Brook, the northern boundary of the bed. In Danvers it is extensively quarried and wrought into mill stones, and into all those architectural articles for which granite is useful. It yields a considerable income to the citizens of Danvers, and has become very celebrated in makirig mill stones of a very superior quality. Another range of sienite, but of different quality, extends from Flax pond in Lynn, to the ocean at Swampscut, (also in Lynn.) This sienite is traversed by numerous trap veins, the feldspar is of a red color, and the proportion of hornblende much less than in the Danvers sienite. This variety of sienite extends on the sea coast from King's beach, Lynn, to the line of Marblehead. A bed of sienite occurs at Beverly, extending in a north east direction from the north end of Beverly bridge, towards the town of Essex. This bed is but a few rods in width ; greenstone trap prevailing on both sides of the road, leading from Beverly to Gloucester, on the south east ; also on the west side of the most eastern branch of the North River, on the north west. This Sienite is also traversed by numerous dykes or veins of trap, which have been injected into it ; some of which are several feet in thickness. In excavating for the Eastern Rail Road, sixty or eighty rods north of Beverly Bridge, these trap dykes are ex- posed to the depth of twenty or thirty feet ; several of which are 80 Prescolt's Sketch of the Geology and Mineralogy so completely disintegrated as to be converted into a perfectly friable earth, or soil, of a dark brown color. This gives to these veins a singular appearance and renders them worthy the atten- tion and inspection of the Geologist. The north eastern section of Nahant, is also composed of sienite. The west part of Nahant, called Bass Point, is com- posed of a different species of sienite, the hornblende and feld- spar being in nearly equal proportions. At the south east part of Little Nahant, occurs a singular rock, composed of hornblende, and a dark reddish brown feld- spar, and may be classed as a variety of sienite. In general sienite passes into greenstone, and often by insen- sible shades, and greenstone may be seen protruding above the surface, near the base of all the hills of sienite, and often crop- ping out at considerable elevations. The same occurs among all the porphyry hills in Lynn and Saugus. Although bowlders of the Danvers sienite are never seen north of the bed, yet at the south, they occur scattered over the greenstone ridges of Salem and Marblehead, and over the por- phyry ridges of Lynn and Saugus. Many are found on Nahant and a large number occurs on Little Nahant. These bowlders resemble the Danvers sienite, and differ from any found in the vicinity. A rock, somewhat different from any other in its composition, but which may be classed with the sienite rocks, occurs in the west part of Topsfield, and the east part of Middleton, near their junction with the north part of Danvers. This rock is com- posed of red feldspar, quartz and green chlorite ; the chlorite taking the place of hornblende. In passing north through Dan- vers, you meet with small bowlders of this rock, several miles before reaching the north line of the town, and as you advance north they increase in size and frequency ; until (within a mile or a mile and a half of the ledge) the stone walls are chiefly composed of it. This ledge or parent rock, you will find in place on both sides of Nichols' Brook, in the corner of Middle- ton and Topsfield. The general aspect of this rock, from the red feldspar, which is the most abundant ingredient, will very readily distinguish it from any other in this section of the county. of the Southern part of Essex County. 8 1 In some portions of it, the feldspar is compact, and the mass appears almost homogeneous. GREENSTONE, Greenstone trap is the most abundant rock in this section. It prevails in Marblehead, Salem, all that part of Danvers north and east of Proctor's Brook, the whole of Beverly, with the ex- ception of the b«d of sienite before described, and the east part of Lynn. Greenstone may be seen also, protruding above the surface, near the base of all the faiils of porphyry, in Lynn and Saugus, and also, at the base of the hills and ledges of sienite^ in Danvers, Lynn, Saugus and Beverly. Greenstone, occurs on the west side of Nahant, including Black Rock, and also on the east part of Little Nahant. Dykes of a fine grained compact greenstone or trap, from one inch to forty feet in diameter, traverse the slate and sienite in every section of Nahant and Beverly, as well as the coarser variety of greenstone in Salem and Marblehead. The greenstone, in this region, presents a considerable diver- sity of aspect, depending on the general structure, or on the size, proportion and mixture of its constituent parts. In some of the more common varieties, the two ingredients are in distinct grains of considerable size, like those of granite, aud sometimes the grains are so minute, and SQ intimately and uniformly min- gled, that the mass appears altogether homogeneous. The chief part of the greenstone, especially in Salem and Marblehead, is injected by numerous veins of sienite, or rather of quartz and feldspar, the hornblende generally being nearly or quite wanting. These veins, which traverse the greenstone in every direction, are, in many places so numerous as to give the rock quite a brecciated appearance. This appearance is very conspicuous at the south end of Beverly bridge ; along the sea- shore at Marblehead, and various other places, where the rocks have been exposed by blasting for the Eastern Rail Road, and for other purposes. Many of the trap dykes are rendered porphyritic, which, by contrasting the crystals of white feldspar, with the black horn- blende of the trap, becomes quite beautiful when polished. Greenstone porphyry, and compact feldspar porphyry passing 82 PrescolCs Sketch of the Geology and Mineralogy into greenstone porphyry, some of which contains crystals, of a beautiful variety of green feldspar, occurs at Nahant and sev- eral places in Lynn, as will be more fully explained under the head of porphyry. PORPHYRY, The only range of porphyry, extends from the village of Wood End in Lynn to Chelsea, through Lynn and Saugus. This range is bounded on the north, by the range of sienite before de- scribed, and on the south, by tide water, varying in breadth from cue to two miles, forming a range of barren hills and craggy cliffs. The base of this porphyry is compact feldspar, its colors various, but generally some shade of red or brown ; but grey, purple and black are not uncommon. Some portion of it is des- titute of crystals, so from this circumstance and its peculiar hardness and fracture, it has generally been considered as a variety of hornstone. The eminence called Lover's Leap in Lynn, and a spur of Pine Hill, half a mile west of Lover's Leap, are composed of a solid mass of this species of compact feldspar or hornstone. It also occurs in beds throughout the whole range of porphyry . The most important localities of this variety of hornstone, are Red Rock, at the west end of King's beach, Wood End, vicinity of High Rock, vicinity of India Rubber Manufactory, Lover's Leap, south east spur of Pine Hill, Lynn, besides several places in Saugus. Several of the trap veins traversing the trap rocks in the va- rious localities of this formation, are rendered porphyritic by containing distinct crystals of feldspar. There are several of these veins or dykes on Nahant, Marblehead and Beverly, which contain crystals from half an inch to two inches in diameter, some of which are hemitrope. This forms the black porphyry of the ancients. The compact feldspar porphyry receives a good polish and will become valuable whenever the wealth and demands of the country shall be sufficient to defray the expenses of quarrying and working it. A peculiar variety of greenstone porphyry oc- curs on Bayley's hill, on the west end of Nahant. The im- bedded crystals are green feldspar, some of which are beautiful. of the Southern part of Essex County. 83 Compact feldspar porphyry passing into greenstone porphyry occurs at Nahant, and about 80 rods south of the Dye Factory, Lynn. SILICIOUS BRECCIA AND BRECCIATED PORPHYRY. An interruption exists in the porphyry range, before described, by a bed of breccia, which extends quite across it, on the east side of Saugus river. This bed is about half a mile in width from its eastern boundary to the river on the west, and not far from one mile in extent from the sienite on the north, to tide water on the south. It has the appearance of being thrown up, in great confusion, forming precipitous cliffs and narrow ravines. A considerable portion of this formation is a conglomerate rock of the grey- wacke series. The celebrated Pirate's Glen, is situated in this region. This bed of Breccia embraces also, Willis' Hill, (or Tower Hill,) on which is situated the Lynn Alms House. An eminence on the west side of Saugus river, about half a mile north west of Childs' Mills, has its southern portion made up of porphyry, and the northern of the same species of breccia, which appears to be composed of fragments of porphyry, compact feldspar, horn- stone, jasper, serpentine; &c. The greatest part appears to be brecciated porphyry, but large portions of it are composed of fragments of the other rocks, but quite destitute of fragments of porphyry, forming a pure silicious breccia. Specimens of this variety can be obtained, that are very beautiful. Brecciated porphyry occurs also at Red Rock, Lynn. And it is a fact worthy of remark, that distinct and isolated fragments of compact feldspar, exist in nearly all the porphyry throughout the whole range ; but in some places they abound much more than in others. A few bowlders and masses are occasionally found, thrown upon the eastern shore of Nahant, 84 PrescoWs Sketch of the Geology and Mineralogy " AMYGDALOIDAL TRAP/** In Saugus, on the west side of the river, between Childs' mills and Saugus factory, is a round isolated hill, from seventy five to one hundred feet in height, in which occurs a rock of moderate hardness, green color, and argillaceous odour when breathed on, containing imbedded in its substance, innumerable white sphe- roidal nodules of quartz, feldspar, and carbonate of lime, from the size of a pin's head to that of a rifle bullet ; but few however exceed the size of an ordinary pea. This is the vari&loid wacke of Professor Hitchcock. About half a mile south by west of the former locality, occurs another of the same rock, but the imbedded nodules are not so numerous as in the former, and some portions of the rock in both localities, are entirely destitute of these imbedded nodules, At the latter locality are several bowlders, of a different variety of the same rock, t)f a rich chocolate color. The parent bed from whence they proceeded has not been discovered. The imbedded nodules are similar to those in the green variety, and of the same white color. In some portions of one of these bowlders, however, the imbedded substance was of a greenish color, and not so distinctly nodular. A little south of the first locality, (the round hill) and in the vicinity of the last, occur numerous bowlders of a conglomerate variety of this rock, consisting of fragments of rounded masses of different varieties, some of which are of the amygdaloidal variety, others not; some a darker, others a lighter green ; some more, while others are less compact. Some portion of this con- glomerate forms a beautiful breccia, and is probably of the grey-wacke series. MAGNESIAN, SERPENTINE OR VERD D 'ANTIQUE MARBLE. A valuable and interesting bed of Magnesian Marble occurs in Lynnfield, and a quarry has been opened near the centre of the town. It is said to extend from three to five miles in a north east and south west direction, but in no place, except at the quarry, has it been found sufficiently soft to be worked with ease. * Varioloid wacke of Prof. Hitchcock, but Dr. Jackson considers it as Amygdaloidal Trap. of the Southern part of Essex County. 85 When first quarried it can be cut with a saw or turned in a lathe, but in this state it will not receive so good a polish. Af- ter being exposed to the atmosphere it becomes dry, much harder, receives a good polish, and is a good substitute for mar- ble where stones of a dark color are preferred. Near the surface, it is so much divided by veins of asbestos and other foreign substances, as to be of little value, except for the manufacture of Epsom Salts ; but at the depth of fifteen or twenty feet, slabs sufficiently large can be obtained, to answer all ordinary purposes. This bed, in all probability, is the dividing line between the gneiss formation on the north west and the sienite on the south east, From 100 parts of this rock, Dr. C. T. Jackson obtained by analysis : Silica, -v^fS?.1 '-"• "• ••'•'':<••' '-'.?-, \"*b''''"^ 37 Magnesia, V": 4 . / ' :'.( ;V^; " .\ 42 Oxide of Iron, , .'*•]• •*' '•1;^' vV ^" v'i • 1'.' /".""'. ~ Water, . -. ; '. /v . . , . . ^ Loss, . . •• ;'.» ' ^ VV*£ ^*:v;/: .... • . . • : ^ 100 Dr. Jackson says, that from 100 grains of the rock, united with sulphuric acid, may be prepared 127 grains of dry Sulphate of Magnesia, or 198 grains of crystallized Epsorn Salts. This will give, by decomposition with the carbonate of soda or potassa, 98 grains of the common carbonate of magnesia of the shops. In Roxbury, works have been erected where Epsom Salts are now extensively manufactured from this rock. SIMPLE MINERALS. CLASS I. ORDER III, GENUS III. LIME. Species I . Fluate of Lime. A few specimens at Nahant, one or two small crystals of Derbyshire spar, also at Nahant. 6 86 PrescoWs } Sketch of the Geology and Mineralogy Species 2. Carbonate of Lime, Calcareous Spar. Var. 1 . The crystallized and laminated, occur at Nahant, and at New Cove, Lynn, some brilliant specimens have been obtained ; but it generally occurs in thin veins, in the trap rocks at the above, and at some other places on the sea coast. Var. 2. Fibrous carbonate of lime — one locality of this va- riety has been found on the east side of Nahant, at Saunders' Ledge. Species 3, Magnesian Carbonate of Lime. Var. I . Rhomb spar occurs at the south eastern part of Na- hant, in a vein in the slate. Var. 2. Dolomite or granular Magnesian limestone occurs, associated with the argillaceous and flinty slate, on the south eastern part of Nahant, between East Point and Castle Rock. Species 4, Silicious Borate of Lime, (Datholite,) A. mineral occurs incrusting the trap rocks at Saunders' Ledge, Nahant, which appears to be datholite ; but as it has not been analyzed, I am unable to speak with confidence. GENUS IV. MAGNESIA. Species 1. Carbonate of Magnesia. Carbonate of Magnesia occurs at Lynnfield, in veins, in the rnagnesian marble of that place. CLASS II. Species 13. Quartz. Var. I. Greasy quartz, occurs in veins in various parts of Lynn and Nahant, but New Cove is the most celebrated locality. Var. 2. Bowlders of common and greasy quartz, are to be found in Danvers, and the numbers increase as you approach the northern limits of the town. Var. 3. A few pebbles of yellow quartz are to be found on the borders of Nahant. Var. 4. Radiated and drusy quartz, occurs in veins in the slate, on the south eastern part of Nahant ; also on the west side of Bass Rock, of the Southern part of Essex County. 87 Far. 5, Crystallized quartz may be found in many places, but very few specimens worthy a place in a cabinet. A very interesting variety of crystallized quartz, however, occurs in a vein in the trap rocks, near Crystal Beach, Nahant. Many of the crystals are tinged with the green chlorite, which is diffused in the trap. The width of the vein is from three to eight inches, and the crystals being attached to the sides at right angles, are variously interlaced with each other ; making it difficult to procure good specimens. The crystals are covered with a coating of drusy quartz, and many of them appear to have been once broken, the two extrem- ities more or less displaced, and reunited, forming an offset. The crystals of quartz at this locality are very easily broken ; occasioned by the chlorite. Sub species 1. Prase. Epidote intimately combined with either quartz, feldspar, or hornblende, occurs abundantly at Nahant, and from thence along the coast to Marblehead. Sub species 2. Chalcedony. A few small pieces of chalcedony have been found on the beaches in Lynn, and among the gravel upon the track of the Eastern Rail Road, Sub species 3. Jasper. Saugus, has long been known as a celebrated locality of jas- per. It occurs of a beautiful red color, in a plain, on the west bank of Saugus river, about qne mile northerly of Childs' Mills. Some portions of it are striped, spotted, or clouded with grey or white. Until recently, this was the only locality of jasper known in this section. It is now, however, well known that great abundance of dif- ferent shades of red, purple, green striped, spotted, clouded, va- riegated and veined jasper, exists, about half a mile west and south west of the former locality, where the finest specimens of each variety may be obtained. Some portions of the variegated, exhibit a beautiful mixture of green and purple, others of red and grey, and others of purple and grey, (or white) with nume- rous ramifications of scarlet colored veins. The veined jasper is a great curiosity ; it is a deep red, or 83 Prescolt's Sketch of the Geology and Mineralogy dark purple, containing numerous ramifications of minute veins of a scarlet color, exactly resembling the minute ramifications of injected blood vessels. These veins become very conspicuous upon being moistened with the breath. Numerous pebbles, bowlders, and masses of beautiful red, purple, striped, and variegated jasper are thrown upon the south west shore of Nahant, between Bass Point and Crystal Beach. Some of the finest specimens have been obtained from this place. The locality of the bed must be beneath the ocean. Sub species 4. Porcelanite and silicious slate, exists at the south east part of Nahant, associated with argillaceous slate, argillaceous carbonate of lime, &c. It occurs also in the western section of Topsfield, arid eastern section of Middleton, and bowlders of it may be found in the north part of Danvers. SPECIES 14. MICA. A foliated variety of black mica occurs on Salem Neck, asso- ciated with feldspar and foliated hornblende. The lamina vary in size from an inch in diameter to minute scales ; and when associated with foliated hornblende, it is difficult for the eye to distinguish one from the other. In this instance the mica seems to have assumed the place of quartz, which enters largely into all the compounds of hornblende and feldspar, but which in this locality is entirely wanting. SPECIES 15. SCHORL. Beautiful radiated black schorl, has been found by Dr. A. Nichols, on a bowlder of hornblende rock, about half a mile north of the South Village in Danvers. SPECIES 16. FELDSPAR. Feldspar, exists in great abundance. It forms an essential ingredient in sienite and greenstone, and occurs crystallized in various species of porphyry, and associated with quartz, horn- blende, epidote, &c. It is of a white, gray, brown, green and red color, and of various shades. Large hemitrope crystals of a grey feldspar, with a pearly lus- tre, occur in the trap rocks, about the middle of the south east- ern shore of Little Nahant, of the Southern part of Essex County. 89 A variety occurs at Marblehead, which very much resembles the opalescent feldspar or Labradorite. It is of a grey color, and occurs in veins in the trap rocks. Compact feldspar exists in great profusion, especially through- out the region of porphyry. A variety occurs at Beverly, (Hos- pital Point) in which are imbedded innumerable minute crystals and grains of quartz. Most of the hornstone and jasper, in Lynn and Saugus, are supposed to be compact feldspar, more completely fused. SPECIES 17, EPIDOTE. An exceedingly beautiful variety of epidote exists, in great plenty, in veins, in the sienite and greenstone at Nahant, either alone, or associated with quartz, hornblende, and other minerals. It occurs also with quartz, in a vein in the sienite at New Cove, Lynn. Associated with other minerals it occurs throughout the coast, from Nahant to Salem, Marblehead and Beverly, forming prase and other aggregates. Epidote also exists in narrow veins, throughout the whole greenstone region. At Nahant, the epidote presents all shades of green, from a greenish yellow to a blackish green, and some specimens are almost black. SPECIES 18. PREHNITE. A beautiful variety of crystallized prehnite was discovered at Saunders' ledge, east shore of Nahant, in Sept., 1837. It was expected this would yield a supply of specimens sufficient for any demands, but upon blasting, it proved that the inroads of the ocean had nearly exhausted the vein. A few good specimens, only, could be obtained. SPECIES 19. ASBESTOS. Fibrous ligniform and compact asbestos, occurs in veins in the hornblende rocks, on the east side of Nahant, (marked on Lewis' map, " the Iron Mine,") These veins are from a quar- ter of an inch to three inches in diameter. 90 Prescotfs Sketch of the Geology and Mineralogy SPECIES 20. HORNBLENDE AND HORNBLENDE ROCK. Hornblende, is diffused in great abundance, forming essential ingredients in greenstone and sienite. It occurs crystallized, foliated and compact, at Nahant, Lynn, Salem, Marblehead, and Beverly. The principal localities of crystallized hornblende are, the eastern part of Nahant, near Hospital Point, Beverly, and Marblehead. The most celebrated localities of the foliated variety occur at the eastern part of Nahant, and Salem Neck. In the latter place it is associated with mica. Foliated horn- blende occurs also in numerous bowlders of hornblende rock, which are found scattered in great profusion in almost every part of Danvers. These hornblende rocks, are more or less im- pregnated with chlorite, which imparts to them a greenish color; the chief of the hornblende is of a jet black, some however has a tinge of green. A bowlder of hornblende rock has been found in Danvers, containing columns or needles' of black hornblende, from half an inch to two inches in diameter, and several inches or a foot in length, crossing each other in various directions, and which, contrasted with the quartz and white feldspar, of which the base of the rock is composed, give it a picturesque appearance, not unlike rocks that are traversed in like manner by crystals of schorl. Bowlders of an indistinct variety of hornblende slate occur at Nahant. SPECIES 21. CHLORITE AND CHLORITE SLATE. Chlorite and chlorite slate exists in the northern and eastern sections of Lynnfield, and the western and north western parts of Danvers. It exists in great abundance in Reading, and part of Middleton, from whence great numbers of bowlders have been carried southwardly into those towns lying in that direc- tion ; some of this chlorite is of the earthy variety, but mostly of the foliated. It is generally of that peculiar green color so com- mon to that mineral, but in Danvers, where it approaches the greenstone, (and is associated with hornblende) it becomes darker, and at last nearly or quite black. Much of the green- stone in that section is impregnated with it. Chlorite occurs at Crystal beach, Nahant, and is associated with feldspar, forming a species of sienite at Little Nahant, of the Southern part of Essex County. 91 Lynn, Middleton and Topsfield. From the latter place great numbers of bowlders are carried into the north western part of Danvers. In all these instances the feldspar is of a red color. CLASS IV. METALS. The southern section of Essex County is very destitute of metals, no metallic bed having yet been discovered ; all there- fore known of the metallic substances is to be found in diffused state. GENUS IV. COPPER. Pyritous copper is found in small masses and grains, diffused through the trap and slate rocks of Nahant. GENUS V. IRON. Species 1. Sulphur et of Iron (Pyrites), is diffused through the trap rocks in many places at Nahant, Lynn, and Saugus, Species 2. Specular oxide of Iron, occurs forming a drusy coating upon the rocks, at the south part of Little Nahant. Species 3. Argillaceous oxide of Iron, (Bog-ore) occurs in Saugus, near the Newburyport turnpike. GENUS VI. LEAD, Species 1 . Sulphuret of Lead, ( Galena) a few particles have been found in the prase of Nahant, and in a vein of carbonate ot lime, near Phillips* beach, Lynn. GENUS VII. MANGANESE. Species 1. Oxide of Manganese, occurs in beautiful dendrites in the crevices of brecciated porphyry, in Lynn, a few rods north of the establishment for the manufacture of India rubber «loth, and at Lover's Leap. But the most splendid dendrites of this oxide, occur in a ledge of porphyry and compact feldspar, at Wood End, Lynn, in the track of the Eastern Rail Road ; while blasting for that road in 1838, vast quantities of the fragments of the rocks thrown out, exhibited upon their surface a most fanciful and splendid display of dendrites.

This beautiful native reptile, first described and figared by Dr. Holbrook, in his North American Herpetology, will be found mentioned in this num- ber under an incorrect name, viz. (Hyla femoralis, var. c.) see page 93. The Genus Hylodea was separated from Hyla by Zitzenger, on account of the absence of a sternum, (breastbone) as in the true Hyla. Our distinguished fellow townsman, Dr. Charles Picker- ing, now attached to the Exploring Expedition, discovered it, in this vicinity, eight or ten years since, and, as a new species, it has been dedicated to him : a tribute of scientific respect. 1839.

BT ANDREW NICHOLS. THIS species of Hyla, called peeping frog, seems to be not well determined. In the Catalogue of the Reptilia of Massa- chusetts, it seems to be considered as Hyla Squirella ? Daudin; the note of interrogation implying doubt as to the correct spe- cific distinction. Yet the Hyla Squirella of the Southern States and our own cannot be confounded. This, with the Hyla versi- color or common tree frog, or tree-toad as it is more usually 7 94 Remarks on Hyla femoralis, fyc. called in this vicinity, whose croaking in the orchards and about our gardens from May to August, is so frequently heard and so little admired, even by naturalists, becomes particularly clam- orous on showery days and in warm evenings. But the cheerful notes of the little peeping Hyla, may be emphatically styled the "Voice of Spring," to the full chorus of which season it so largely contributes. Description. The Hyla femoralis or Peeping Frog, is about one inch in length, of a fawn color, with delicate dots of black about the body. These dots in two rows form a cross upon the back. The eyes are very prominent, limbs long, slender, formed for great activity. In fine, it possesses in a high degree that form and beauty, and that most graceful motion, peculiar to the frogs. The Hyloe or tree frogs, differ only from other frogs in the extremities of the toes, each of which is expanded into a rounded viscous pellet or tubercle, enabling them to adhere to the sur- face of bodies, and to climb trees and bushes ; where, in fact, they remain all summer living upon insects. Many of them, chameleon-like, have the power of changing their color to that of the bark of the tree to which they adhere ; consequently they are seldom noticed. They spawn in water, and in winter enter the mud. The male has a pouch under the throat, dilating when- ever he cries. Natural Science so forbidding to most minds by its systems, is happily relieved by its Poetry, Who, unmoved, can listen to the voice of spring — to the song sparrow — to the blue bird, and even to the little peeping frog ? And what are these emotions, which fill the soul with gladness, but the poetry of Nature — of Life ? The human mind is inquisitive. It wishes to know more and more of the objects — the beings which afford it pleasure. Many of our race have received delight from even the Hyla, who knew nothing of the creature save its voice. Spring after spring it has saluted their delighted ears, from every fen and morass, like a fairy sound, telling them that " the winter has past — the time of the singing of birds is come." But few, very few, even of our rural population, whose dwellings are in the midst of myriads of these beautiful, active and cheerful little rep- Remarks on Hyla fe moralis, $c. 95 tiles, ever saw the frog itself ; or at least they never recognised it as the creature to which they are indebted for so much plea- sure. The "voice of the turtle," so often mentioned in Scrip- ture, in connexion with the text above quoted, probably gave origin to the singular notion somewhat prevalent, that the spotted backed turtle, (Emys punctata) was here implied, which inhabits the same morass whence this shrill sound proceeds. Others suppose it to proceed from the speckled frog, (Rana fontinalis) or from some species of this family, with which they are better acquainted. About forty years since, a farmer boy, I first satisfied my own curiosity by catching the creature in the very act of vocif- erating, the well known monosyllable peep — peep* This was effected by wading, soon after sunset} into a wet meadow where these frogs were numerous. As I approached, every voice was hushed, every head hidden. I stood perfectly motionless for a considerable time, until at length an individual near my feet resumed its piping. Presently the inflation and collapse of the membrane beneath the throat, (occasioning the emission of sound) caught my eye. In the twilight, nothing more of the creature could be seen. With a quick motion, the frog, together with a handful of mud and grass, was seized, borne in triumph home, placed in a glass vessel, and examined at leisure. The piping of the Hyla commences 'as soon as the frost is out of the swamps, in which they have hybernated, and is continued usually through the month of May. They are silent, in summer. The same note from a solitary individual on some tree, vine or bush, is sometimes heard in autumn ; but whether it proceeds from the same creature or from some other, that mimics its voice, I have never been able to determine. It is not improbable how- ever, that though thus out of season, it comes from the frog itself. Thus also in the autumn a few trees* will blossom, and birds| sometimes resume their spring notes. So likewise may it not be inferred, that this favorite saluter of Spring, sometimes though rarely, exhibits this anomalous trait ? * The apple avd pewr; Cinnamon Rose) (Rosa dnnaanomea] Japan Quince, (Cydonia japo- H/crt) occasionally blossom in autumn. f The blue bird (Sylvia sialis.

NOTICE OF RARE PLANTS ; WITH A DESCRIPTION OF A CURIOUS VARIETY OF CLADONIA UNCIAL1S. By JOHJI LEWIS RUSSELL. CHARA VULGARIS. L. Bigelow's Plants of Boston, 2d ed., p. 334. Natural order Characeae. Richard. I met with this obscure but exceedingly interesting aquatic, for the first time, in a brook, running parallel with the Eastern Rail Road, on the farm formerly in possession of I. Tucker, Esq. While, with a friend, searching for microscopic objects among the Infusoria, my attention was drawn to the floating tufts of this brittle and crystalline plant, growing from the bottom. Submit- ting it to the microscope, we had the pleasure of perceiving the motion of the sap in those mysterious and beautiful currents, better known among botanists as Cyclosis. Vesicles of a glob- ular form were perceptible traversing the internal cavities and Notice of rare Plants, 8$c. 97 vessels of the plant, sometimes in direct, but mostly in spiral channels, now flowing with accelerated motion, and now in a slower degree. Whenever internodes, or even the apparent rudimentary gems of a new branch occurred, these globules would contract so as to allow their passing round the knot, and on being relieved from such constraint, would instantly recover their former size and shape. I would here observe, that to appreciate fully the beauty of this phenomenon, the microscope must be of a deep penetrating power, and if convenient, an achromatic lens should be em- ployed. For further particulars of this curious subject of Cyclosis, the reader may consult with advantage the ingenious papers of Messrs. Varley and Slack, in vol. xlix., of London Transactions of Arts and Sciences, p. 179 and seq., plates. Different opinions seem to have been entertained respecting the position, which this plant should hold among the classes and orders of the vegetable system. Vaillant, first established the Family of Characeae in 1719, when it contained the single genus Chara. Linnaeus, at one time placed the plant in his Crypto- gamia, but afterward removed it to his class and order Monoecia, Monandria : while Richard grouped the Characeoe among Acotyledonea3, to which they seem allied and approximate to Marsilea, in the common structure of their seed-vessels. The original specimens collected as mentioned above, have been growing during a space of eighteen months, in a vial closely sealed, making a profusion of new branches and seeds. ZOSTERA MARINA. Linnwi species Plantarwn, 1374. Eel grass. Sea-wrack. Natural order. Fluviales. Lindley. In a search for shells on Plymouth Beach, last summer, I had the good fortune to find several specimens of this plant in full fructification. Dr. Bigelow, in his Florula Bostoniensis, men- tions that he had never been able to discover it in this condition. The fact is worthy of notice. The fruit of the Zostera is disposed in two rows, in sheaths formed from the dilation of the leaves, infolding, like the spathe of an Arum, but confined to the middle ; the leaf assuming its usual ribbon-shape immediately above the seeds. Each of these 98 Notice of rare Plants, fyc. seeds is cylindric, beautifully ribbed lengthwise, and somewhat wrinkled between the ribs. The albumen, of a singular blue color. On comparing a specimen with the fine figure of Prof. Hooker, in Flora Londinensis, and again with T. 467 of English Botany, and also through the suggestion of Geo. B. Emerson, (President of the Boston Society of Natural History). I am inclined to think, that ours is a distinct species, though seemingly heretofore confounded by American Botanists, with the British species. A subsequent examination gave me the following results, viz. 1. Greater length of leaves : ours being many yards — the British according to Hooker " from four inches to a span long." 2. Want of distinct sheaths, at base of leaves. 3. Leaves of American species, mucronate, (ending in a short point :) while those of the British species are " obtuse at the extremity." 4. Flower-sheath at a greater distance from the sheaths, than is represented in the figures of Hooker, and English Botany. This part of the subject will receive further attention. Zostera belongs to the natural group of Naiadre of Jussieu, and Potamophilae of Richard, and Fluviales of Lindley. Lin- noeus places it in Gynandria ; Withering in Polyandria, Polygy- nia ; and in this country Elliott, Nuttall and Bigelow, consider it as referable to Monoecia. Its Spathseform floral envelope allies it to Aroideas, as noticed by Richard, who also points out the real distinction between each. EcHIUM VULGARE. L. Viper's Bugloss. Bigelow 's Plants, &c., p> 70.

The genus Cladonia to which this curious va- riety belongs, is distinguished by its upright and fistulous stems, furnished with numerous branches, each tipped with a small black, brown or red body (its propagulum) or organ for contin- uing the species, analogous to those stem-bulbs seen on some kinds of the more perfect vegetables. Whoever has rambled over dry pastures in the months of summer, must remember the crackling under feet, of species of this group of brittle coral-like plants. In it may be found the valuable Rein Deer Moss C. rangife- rinum, and the beautiful scarlet C. bacillaris, which delights to grow on decayed trees, posts, rails, and is not unfrequent in the interstices of large sunny rocks contiguous to the forest. The subject of the present observations was found in Hing- ham, Plymouth County, on a mild sunny day of the last winter, and subsequently in great abundance at the same place among the mossy rocks of a pasture, south east of " Tranquility Grove ; " a sylvan retreat well known to the inhabitants of that town for its delightful shade, and pleasant summer pic nic par- ties. I have given it the name of Netted Cladonia or Coral Lichen, and consider it the fifth variety of Cladonia uncialis, of which Acharius in his Prodromus, has mentioned four pre- viously ascertained. REMARKS UPON SCARAB^US GOL1ATU3 AND OTHER AFRICAN BEETLES ALLIED TO IT. BY THADDEUS WILLIAM HARRIS. THERE has recently been added to the Cabinet of the Society a gigantic beetle, belonging to the genus GOLIATH of De La- marck. The enormous size4 extreme rarity, and great nominal value of the African insects of this genus, render the acquisition of this specimen, which is in perfect preservation, an occurrence of signal good fortune, and affords a suitable occasion for some remarks upon the species. The earliest account of them on record is contained in Dru Drury >s* " Illustrations of Natural History," a work in three volumes, quarto, published at London in 1770, 1773, and 1782, and illustrated by figures of exotic insects, drawn and engraved by the celebrated entomologist Moses Harris. Mr. Drury seems, for many years, to have been the only possessor of one of these beetles, which he states was brought from Africa, where it was found dead and floating in the river Gaboon, oppo- site to Prince's island, near the equinoctial line. It is said that this specimen cost Mr. Drury the sum of ten pounds sterling, a high price as compared with the present diminished value of money. This beetle was described and figured, in 1770, in the first volume of Drury ?s Illustrations, page 67, plate 31. From this description and figure Linnseus drew up a specific character of it, and inserted it, in 1771, in his "Mantissa altera," under the name of Scarabceus Goliatus, a name which was subse- quently adopted by Drury, in the index appended to the second volume of the Illustrations. Mr. Westwood, the editor of a * Mr. Drury was a London goldsmith and jeweller, who devoted his leisure to the study of natural history, and particularly to that of entomology, and was a fellow of the Linnaean Society. His collection, in the increase of which he spared neither expense nor trouble, contained eleven thousand insects, which after his decease, were sold by public auction. Mr. Diury was of a very ancient family, and it is believed was lineally descended from i*ir Dru Drury , of Q,ueen Elizabeth's time. He died on the 15th of January, 1804, at the ad- vanced age of eighty. His son succeeded to his business, and his daughter was married to a Mr. Andre, a merchant in London, and unele to the unfortunate and lamented Major Andre. See Gentleman's Magazine for 1804, part 1, p. 86. 8 102 Harris's re.nwks upon Scarabceus golialus, fyc. new edition of Drury's work,* informs us that this specimen of the Goliatus came into the possession of Dr. William Hunter, who subsequently bequeathed it, with his own collection, to the University of Glasgow, where it is still preserved, and forms one of the most interesting objects of the Hunterian museum. This beetle remained, for a long time, unique in Europe ; but there is now another one, resembling it in color, but of inferior size, and with the horns on the head not so much developed, in the magnificent collection of W. S. Macleay, Esq., of London. While the Goliatus was in the possession of Dr. Hunter, it was seen both by Fabricius and Olivier, and the latter took a drawing of it for his {{ Entomologie," where"]" it is referred to the genus CETONIA. More recently it has been a third time figured in Mr. Duncan's volume on beetles, pi. 16, belonging to Jardine's " Naturalist's Library." Although it has been repeatedly rede- scribed and refigured, I believe that these are the only original figures, and that all the others are mere copies from them. The Chevalier De Lamarck, having found it expedient to propose a new genus for the reception of the Scarabceus (or Cetonia) Goliatus and some other allied insects, regardless, as he always was, of the rights of his predecessors, converted the Linntcau specific name for the insect in question to the generi- cal name of Goliath, and substituted that of Jlfricanus for the species. The characters of this new genus were published, in 1801, in the Systeme des Animaux sans Vertebres," and the general name was retained by Latreille in the first volume of his " Genera Crustaceorum et Insectorum," which appeared in the course of the same year. Now, however, this name is usually written Goliathus ; and to the species, instead of Jffricdnus, that of giganteus, proposed by Mr. Kirby,J is applied, in the new edition of De Lamarck's "Histoire Naturelle des Animaux sans Vertebres," and in Westwood's edition of Drury's work.§ Mr. Duncan calls this same species Goliathus magnus. * Illustrations of Exotic Entomology, &c, by DruDrury; a new edition, with additional matter by J.

Introduction to Entomology, Vol. Ill, p. 33. $ Alluding to this species, in the third volume of Drury'a work, pp. 54 and 55, Mr. Westwood, apparently through inadvertence, calls it Goliath, maxtmus. Harris's remarks upon Scarabwus goliatus, fyc. 103 The second species, and in point of time the second described individual of this genus, was also contained in Drury's collec- tion, and was first described and figured in 1782, in the third volume of this author's Illustrations, page 55, and plate 40. It was procured near Sierra Leone in Africa. Drury says of it, that " this ^insect is of the same genus with that described in Vol. I., plate 31 ; but I judge it to be a different species ; " and "it is an undoubted nondescript." Subsequently, however, Drury inserted this species in the index to his work as a variety of Scarabaius Goliatus. Mr. Westwood considers it to be a distinct species, and, in his edition of the Illustrations, names it Goliathus Drurii, in honor of its first describer. At the sale of Drury's insects it was purchased by Mr. Macleay, senior, for the sum of £12. 1. 6. sterling, and still remains in his collec- tion. Mr. Westwood says that "a very fine and recent speci- men has lately been received by Mr. Havill, of Oxford street, (London), printseller and naturalist, who has demanded the sum of fifty pounds for it ; " and I am informed that he has actually been offered and has refused forty pounds for the specimen. The insect in the Cabinet of the Society is the third known specimen of Goliathus Drurii. It agrees with Drury's figure in all essential characters, and, to the best of my recollection, dif- fers from it only in having- a few white dots on each side of the great white patch on the elytra, not symmetrically arranged, but placed irregularly near the margin of the patch. It was pre- sented to the Society in November, 1837, by Dr. Joseph Far- num, of Salem, and was brought to this place from Africa by a seaman, whose account of it is substantially the following. About two years ago he was on board of a Salem trading vessel, which put into a small port on the western coast of Africa, be- tween Sierra Leone and Cape Palmas. Whilst there the vessel was visited by the natives for the purpose of trade, and one of them brought this beetle dead, and in the state in which it now remains. The natives, furthermore, said that these insects fly about in the woods during the night. In 1785, Voet* figured and described another species of this genus under the name of Cacicus ingens. It is smaller than the * Besclireibungen und Abbildungen hartschaaligtcr Insecten ; Coleoptera, Linn. Vol. I., p. 101. pi. 22, fig. 151. Quarto, Erlangen, 1785, &c. 104 Harris's remarks upon Scarabceus goliatus, $c. two preceeding species, and the elytra are entirely of a pearl- white color. The specimen was stated by Voet to be a native of America, and to belong to Renger's rich cabinet. Olivier and Fabricius call this species Cetonia Cacicus, and repeat Voet's statement, that it is a native of America. Mr. Hope, in his little work, entitled " the Coleopterist's Manual," puts down the Cacicus as a native of Guinea, from which place he says that he has received a specimen. In the Cabinet of the Mu- seum of Natural History of Paris is another specimen, which, though it resembles Voet's figure of the Cacicus in most re- spects, differs from it in having a triangular black spot on each elytron, near the humeral angle. Messrs. Gory and Percheron have described and figured it in their " Monographic des Ce- toines," p. 150, pi. 24, fig. 2., and give, as its native country, South America, but state that this locality is not indeed certain. Dr. Klug is said to have described a female of some species of this genus in Erman's "Reise," under the name of Goli- athus regius. The description I have not yet met with ; but Mr. Westwood, who saw the insect in the Royal Museum at Berlin, says that it has the head unarmed, and that it agrees in color and markings with the G. Drurii. One more insect belonging to this genus, as restricted by Mr. Hope, remains to be noticed. It is in the cabinet of Mr. Hope, who received it from Guinea, and ascertained it to be a female by dissection, and, on the fifty ninth page of his " Manual," states that he thinks probably it is the female of Goliathus giganteus. While the Manual was passing through the press, Mr, Hope added some interesting observations on the Gol- iathidae, together with a full description of the foregoing female, under the provisional name of G. princeps, with the following remarks. " In the present state of our knowledge it is difficult to decide with certainty whether this insect be the female of any of the already described, or of a still unknown, species. It is better therefore to give it a provisional name, although the insect is evidently a female, than let it remain undescribed. At a fu- ture time it can be changed when more accurate information is obtained." A beautiful figure of this insect, from the accurate pencil of Mr. Westwood, is prefixed to the Manual, from which, and from the description, it appears that the edge of the clypeus is rounded and unarmed, like that of the regius. Harris's remarks upon Scarabccus goliatus, fyc. 105 The genus Goliathus, as restricted by Mr. Hope, has the thorax rounded, is peculiar to Africa, (for it seems that the Cacicus is really an African and not an American insect,) and contains, at present, only the five foregoing insects, or species, if they be truly distinct from each other ; and, of these Goliathi, only the ten individuals, which I have enumerated, are, as yet, known ; namely, eight males and two females. It is much to be regretted that De Lamarck's numerous and unwarrantable innovations in nomenclature* should- still be re- tained. Specific names are the property of the first describers who make use of them, and should not be altered or removed. It seems to me, in the present instance, no more than an act of justice to restore the original Linnasan specific name to the typ- ical species of Goliath, or Goliathus, and to give to the genus another appellation. I propose therefore to call the latter Hegemon^j and add a brief description of the insects included in it. Genus HEGEMON. Harris. 1. H. Goliatus. Clypeus bifurcated ; thorax black, with seven whitish stripes ; elytra chocolate-brown, margined be- fore with white. Length over four inches. 2. H. Drurii.

Mr. Hope, in the little Manual before mentioned, proposes to divide the Family Goliath-Ida, as he calls it, into two groups ; the first including those genera in which the thorax is rounded, and the second those in which it is trapezoidal, or broad behind and narrowed before. In the former he places three genera, Goliathus (Hegemon^), Dicronocephalus, and Incas ; in the latter, Mecynorhina, Dicronorhina, Rhomborhina, Jumnos, and an un- named genus, the type of which is a Mexican insect, the Goliathus Hoepfncr of Gory and Percheron.* The genus Incas or rather Inca of Lepeletier and Serville comes very near to Trichius, is peculiar to South America, and contains some spe- cies of large size and considerable rarity, but which cannot compare, in these respects, with their African prototypes. Mr. Hope does not inform us by whom or where the characters of Dicronocephalus are defined, nor does he name the species upon which the genus is founded ; but merely gives it as an East Indian genus. I think it probable that the Goliathus Wellech (Wallich ?), of Gory and Percheron,f may be the type ; and, if this be the case, the East Indian genus Narycius of Dupont, in Guerin's " Magasin de Zoologie," for 1835, pi. 128, will probably have a place very near to it, in the first group of this family. The characters of the first three genera in the second group, with a trapezoidal thorax, are given by Mr. Hope in the Manual. To Mecynorhina, the magnificent Scarabceus Torqua- tus of Drury is probably to be referred, the male of which has recently been described and figured, for the first time, by Mr. Waterhouse, in Charlesworth's "Magazine of Natural His- tory," New Series, Vol. II., page 635. Of this insect, which is nearly three inches in length, or scarcely inferior in size to the species of our genus Ifcgemon, and is also a native of the western part of Africa, only two individuals are yet known ; one, a female, with the clypeus unarmed, the original unique specimen from Drury's cabinet, "is still in existence, and graces the rich collection of Mr. Macleay ; " the other, a male, with the clypeus produced into a long, pointed, recurved horn, was lately obtained at Sierra Leone, by Lieut. Strachan, in * Monogr. des Cetoines, page 154, pi. 2G, fig. 2. | Monogr. des Cctoiweg, page 154, pi. 2G, fig. 1. Harris's remarks upon Scarabceus goliatus, fyc. 107 whose collection it is preserved. The type of this genus is the Celonia Polyphemus of Fabricius. The following remarks, made under this species by Mr. Hope, may serve as a caution to those persons who possess rare and valuable insects, and will show to this Society the necessity of immediately providing for the safe keeping of their specimen of Hegemon Drurii. " This insect (Mecynorhina Polyphemus), for many years, was consid- ered unique, and was the chief ornament of the Banksian cab- inet : it has been stolen from thence by some individual un- worthy of the name of naturalist. I regret to state also that a box, containing some rare and singular insects, from Sierra Leone and New Holland, has disappeared from my own collec- tion." The Polyphemus, however, is not lost to science ; for it seems that there is a specimen in the cabinet of Messrs. Gory and Percheron, who have described and figured it in their Monographic. JOURNAL OF THE ESSEX COUNTY NATURAL HISTORY SOCIETY. THIRD AND LAST NUMBER. IN bringing the Journal to a close, a few words may be expected by way of preface. Since the issue of the second number, materials of vari- ous character have been from year to year collecting. These were offered at the annual and other meetings of the Socie- ty in the form of verbal and written Reports. From them the present number has been compiled, by reference to the Specimens in the Cabinets, to the Records and to the files in which memoranda as well as the reports had been pre- served. The collections have increased within the last twelve years to a gratifying extent. Each department of Natural History has its Representatives. The Herbarium is rich in native and foreign species. The Conchological cases ex- hibit our own Mollusca arranged side by side with British cospecies. Other foreign species of Shells have been secur- ed by private generosity or by a system of exchanges. The same may, in fine, be said of all the other departments. Of the natural history of Essex County much knowledge has been gained. The geological features of a section in the immediate vicinity of the City of Salem have been rendered interesting by the Society's possession of a natural curiosity, familiarly known as Ship Rock, a massive boulder, to which reference may be made in this number. The Mi- croscope has likewise been employed, and some of the ear- liest instances of Silicious Earths, containing infusorial re- mains, occurred within our immediate neighborhood. We have called this the third and last number, and we 110 Retrospect of the Shells of Essc.r County. here take leave of our Journal as an indication of the doings of the Essex Count/ Natural History Society. The ESSEX INSTITUTE was formed in 1848, by the union of the E. 0. N. H. Society with the Essex Historical Society, and duly in- corporated by an Act of the Legislature. All future publica- tions of our research or discovery will be issued under the name of the Proceedings of the Essex Institute. Salem., March, 1852, RETROSPECT OF SOME OF THE SHELLS FOUND IN ESSEX COUNTY. In the second number of this Journal will be found a sketch of some of the shells (Mollusca) which had occurred to the writer. A reference therein to the materials of his "Familiar Notice, &c." exhibits the facilities of which he was possessed. The number was issued in June, 1839. In 1841 the State Report of Dr. A. A. Gould was published. Subsequently communications appeared in the Journal of the Boston Society of Natural History, in later volumes of Silliman's Journal of Science and in Proceedings of Scien- tific Societies, detailing new facts in this branch of Zoology. The present paper is intended as an alphabetical list of those species alluded to, in the second number, and they are now arranged according to the nomenclature of Dr. Gould.

OCCURRENCE OF SCAPHIOPUS SOLITARIUS, IN ESSEX COUNTY : WITH SOME NOTICES OP ITS HISTORY, HABITS, &c. BY ANDREW NICHOLS, M. M. S. S-, Presi- dent of the Society. Read June 17, 1843. In a shallow basin surrounded by ledges of greenstone rock, which retains water during the winter and spring, and is occasionally rilled in summer by great rains to the depth of one to four feet, on the brow of a hill in Danvers, over which the old Essex Turnpike crosses, and near the intersection of this road by the Newburyport Turnpike, an interesting colony of this rare reptile, hitherto unobserved north of South Carolina, has been lately discovered. Some- 114 Nichols on Scaphiopus Solilanus. where-about the years 1S10; 1S11 or 1812, subsequent to a great rain in summer, several frogs of this curious species were noticed by John Swinerton, Esq., now deceased, who resided very near this spot for sixty successive years, and had ample opportunity to observe them. Their numbers, in this, their first appearance, was as great as at any time since; determined by the testimony of several witnesses. At this time, during one or two days and nights, they were very noisy and actively engaged in fulfilling the great fiat of creation; and soon afterwards they disappeared. Nothing more was seen of them for several years. Their voices or note so nearly resembled that of young crows, that it at- tracted the attention of a Mr. Elijah Pope, a farmer, who lived half a mile distant ; and, accompanied by his son, sallied forth, gun in hand, to kill what he so naturally im- agined were mischievous birds in his corn-field. From this little anecdote I am enabled to determine their first ob- served appearance with some degree of certainty ; thus de- fining the time as about the first of September, when corn is in a state to be fed upon by the crow : while, again, the years mentioned above, agree with a statement of the son, Mr. N. Pope, who from his own present age, concludes that 1812 or a year or two earlier, was the time of their first visit. So far as recollection serves, nothing more was seen of them, until July, 1825, on a day memorable for the passage of LA FAYETTE over the Newburyport Turnpike close by, on his return to Boston from his eastern tour; at which time their voices added to the welcome greetings of a nation's guest ! Since this last date, thus rendered conspicuous as well as certain, whenever the basin has been filled in warm weather, these reptiles invariably make their appearance. This has occurred, however, only three times, viz. : August 12th, 1834: again in the summer of a year whose date is forgotten; and on June 16th, 1842. The forenoon of this day, last mentioned, was dark and rainy, as the day and night previous had been. Their croaking attracted the at- tention of an acquaintance of miiiCj and information of their Nichols on Scaphiopus Solitarius. 115 appearance, with a pair of the frogs, were forwarded tome by Mr. Amos Swinerton. In the afternoon of the same day, I repaired to the spot, accompanied by several members of the Essex County Natural History Society ; but the sun had appeared meanwhile, — their voices were hushed, and none were even to be seen. In examining the water, however, we found it filled with spawn — and two females were drawn from the bottom of the pool. In the evening follow- ing they came out again ; resumed their croaking and ama- tory habits. Several more specimens were captured and kindly presented to us, by Mr. Nathl. Pope, whose name has been already mentioned. The old frogs were not seen again. In five days after, I found the spawn had become tadpoles, of which about a hundred I took home — kept them in glass globes, — fed them on fish and flesh — scarcely one died. They remained longer and grew larger in the tadpole state than did those left in their native pool, which latter became perfect animals in less than four weeks. On the other hand, those kept in water, without any opportu- nity to crawl on land, or on any substitute for it, such as a floating chip, or some foothold firmer than water, were slower in their development. It seems then, that the de- velopment and successive changes of the organs, conform to circumstances. So long as water is wholly their resi- dence, their caudal appendage is necessary and according- ly used, retaining its proportionate size and strength, and the growth of the legs is in the same proportion. If the wa- ter be gradually withdrawn, and mud, moist earth and then dry, gradually substituted, they will much sooner undergo the change from the embryotic to the infantile condition of existence. Thus, at the end of four weeks, all the water in which the spawn was deposited had evaporated ; in some of the lowest spots of the basin a little mud of the consist- ence of clay-mortar alone remaining. Here the young frogs were merrily hopping about, enjoying life on dry land, while those in confinement in water, were still increasing in size, and yet in an embryo condition. This very short natural period of the tadpole state admirably fits them for 116 Nichols on Scaphiopus Solitariits. such breeding places as the one in which the subjects of this paper were found; a locality where water can remain for a short time only, and this in the most wet seasons. I also kept a few of the old frogs, three in number, two females and a male, in a barrel, a third part filled with moist peat muck, containing some earth worms* and other small creatures. Occasionally I threw in a few garden snails,! small pieces of meat, fish or insects. Whether they ate of these provisions is uncertain. Occasionally I found one or two of them out of the mud, in which they usually buried themselves, reserving only a small breathing hole, opening above their heads. I frequently shook them out for the purpose of exhibiting them ; but they would soon bury themselves again, by the dexterous use of their hind feet. I kept them till the last part of November, when care- lessly permitting the earth to become frozen, they were killed. Holbrook, in his N. A. Herpetology, vol. L, pp. 85-7, says that he has found these reptiles in three states only, viz : Georgia, South Carolina, and Tennessee — that they go into the water only in the breeding season, which he ob- serves is in the spring ; and that they live in holes in the ground of about six inches in depth, excavated by them- selves— never coming out of these, except during the night or after heavy rains. This explains the mystery of their sudden appearance and disappearance, as above mentioned. It would also seem that they are Southern reptiles ;— chilled by our northern climate, they want a more genial season to celebrate their nuptials ; and thus without a suitable pool to receive the spawn, year after year in this instance trans- pired, until a summer freshet filled their native habitat suf- ficiently. I have some reasons to conjecture that other colonies of these frogs exist in New England. An intelligent farmer ofTopsfield, (Mass.), to whom I showed my specimens, and related the foregoing history, told me he had several times heard a similar croaking in a temporary pond of wa- ter near his dwelling, but he never went to see from whence *Lumbricns terrestris, L. tLimax agrestris ? L. The Polylrichaccfc of Essex County. 117 the noise proceeded. Something of the same kind has been noticed also in Framingham, in this State, by a stu- dent of medicine, who relates that he and a friend of his were kept awake on the identical night, June 16th, 1842, by the noise of frogs or something of the kind in a ditch of water near his lodging ; that they went out to discover what they were, but on drawing near the place, the noise or cry, which resembled that of young crows, suddenly ceased, and nothing was to be seen. OBSERVATIONS ON THE POLYTRICHACE^E ; with a notice of some species occurring in Essex County, Massachusetts. This family of the mosses, embraces several distinct genera, which formerly were all comprised under one genus, and known as Polytrichum. Growing in situations sub- jected to alternate dryness and moisture, the polytrichnms are found inhabiting wide-apart regions of the globe. Assuming a gregarious habit and in many instances corn- posing a close turf of perennial continuance, they are well adapted to clothe the surface of the earth, in high northern latitudes. Particular species are decidedly montane and even alpine, while again on the other hand several grow in rocky situations, near the sea coast. The polytrichums are mosses of an upright form, bearing on the summits of the stems and embosomed in the foliage, two kinds of reproductive organs; the one consisting of a series of stiff and colored bracts of a stellulate outline, enclosing the antheridia and pistillidia, from the latter of which, the future seed-vessel (capsule) is gradually pro- duced. Sometimes however the stellulate appearance remains, crowning the summit, and on the next annual growth furnishing a continuation of the stem from its midst, which is also provided with the regular foliages, and the individual plant is thus for a time in a sterile condition. The office, which the antheridium and pistillidium perform 2 118 The Polytrichacea of Essex County. is supposed to be analagons to that of the stamen and pistil in the higher plants. The pistillidium elongates and rises to a considerable height, constituting the pedicel; and en- larges at its apex into the capsule, which is surmounted by a caplike organ, called the calyptra. On the ripening of the capsule the calyptra falls off, but when studied with other structural differences, it forms a good criterion to divide the many species into the several genera, Thus, in Polytrichum proper, the calyptra is densely hairy, while the capsule, which it invests, becomes, when mature, of a four or six sided figure. The name Polytrichum is derived from an allusion to the character of the calyptra, polus being the Greek for many and thrix Gr. for hair, so that it may be familiarly termed, the haircop or the many haired moss. In Pogonatum, the calyptra is hoodshaped and also dense- ly hairy, while the mature capsule is cylindrical, so that these forms distinguish it. From pogon Gr. beard we derive Pogonatum the bearded hood moss, or bearded cap moss. In Atrichum, the calyptra is smooth, but its tip is spinu- lose, its form is hood shaped, and the capsule is elongated- cylindraceous and slightly curved. Hence the smooth ca- lyptra is signified in the generic name, a, (privitive) without and thrix Gr. hair, the hairless cap or smooth cap moss. Further distinctions need not be pointed out ; these general and more obvious characteristics being deemed sufficient to our present purpose. We come to an enumeration of the species according to our plan. 1. POLYTRICHUM COMMUNE. Linnesus Species Plantarum, p. 1573. Hooker and Taylor's Muscologia Britannica, 2d Ed., p. 46, table X.

This species is to be found in moist places, and as its name implies is a common plant. It varies considerably in sizes. Its capsule is four sided and acute-angled, which the ferruginous colored hairy calyptra completely "covers, extending below the base : its operculum (the lid covering the orifice of the capsule) is short* The stem} which rises The PolytrichncccB of Essex County. 119 from the earth, is simple and clothed with linear-lanceolate shaped leaves, which are bent backwards when in a fresh state, and are likewise serrate on their margins and backs. We are informed by Linnaeus that this moss enters largely into the comforts of the inhabitants of Lapland, who use it for bedding and similar purposes. "In the north of Eng- land, mattresses superior to those of straw are sometimes made with it, and Burnett also adds, after quoting Johnston, for the last statement, that it " was formed for promoting the growth of the hair, and that in Germany it is esteemed as a sudorific.' " Outlines, vol. I, pp. 287-8. Nor less in- teresting is its geographical distribution, having been found throughout Europe, in temperate and frigid parts of Asia, in Kamschatka, North America, Newfoundland, Peru, the Falkland Islands and Madagascar. 2.

They are found in great numbers throughout the whole extent of Massachusetts, are usually somewhat rounded in outline, and are rendered quite smooth by attri- tion or by atmospherical agency. Russell on some Polylhalamia. 121 SHIP ROCK stands upon the summit of a precipitous cliff, about half a mile distant from Tapley's Brook, and directly I'.orth of the dwelling house of Mr. David Newhall, on the road to Lynnfield. It is of granite, and measures forty-five feet in length, twenty-two in height and twenty-five in width. Its shape is tolerably regular, resembling in some respec(s an inverted vessel, whence its name, but not ad- mitting of a very exact measurement. Supposing its mean circumference to be one hundred feet, its diameter would be about thirty feet, and if it were spherical, its weight would be about eleven hundred tons. The area surrounding the Rock is also covered with loose masses of stone, many of which are estimated to weigh from fifty to seventy-five tons. MINUTE POLYTIIALAMOUS SHELLS OCCURRING ON THE COAST OF MAINE, NEW ENGLAND. By Jous LEWIS RUSSELL, Member of the Society, &c. Read June 29, 1842. The advantages which the microscope affords the natur- alist, seem likely to be appreciated in these times of general inquiry. Worlds of beauty — rare gems of exquisite per- fection, and objects of consummate skill, with unsurpassing instances of design, are daily unfolding themselves to the curious eye. The representatives of animated creation in the lower forms of animal and vegetable life, so minute as to escape the common observation are revealed by this instrument in modes well calculated to excite surprise, admiration and instruction. The sands on the calcareous coasts of England, present a variety of the most beautiful forms of minute creatures belonging to the order of FORAMINIFERA, established by D'Orbigny. They serve a similar purpose as the silicious coverings of the infusoria, in making up by their vast con- geries, entire strata and large proportions of soil in different parts of the world. " The sea downs of some and probably of most coasts are still in course of formation by living Bryozoa, which though very small, resembling grains of 122 Notices of several Fishes of Rare Occurrence. sand, are yet for the most part larger than chalk animal- cules, and a large proportion of the sand of the Libyan Desert has been proved to consist of such grains." Wea- ver's Views otEhrenbergs discovery, in PhilosophicalJour- nal of London and Edinburgh, vol. 18. p. 386. I have seen no notice of these minute shells in this country excepting an accidental one by Dr. A. A. Gould, in his Report on the Invertebrate animals of Massachusetts, in the following words, viz : "Of the very curious and minute Nautilacess, so many of which have been found about the British islands, there are doubtless many among the sands of our shores ; but none have as yet been detect- ed." p. 317. During the month of August, 1841, 1 had the satisfaction of finding several of these "curious and minute" shells, mixed with sand, adhering to a species of marine Conferva on the beach of Kennebunk, Me. Two distinct species of these were nautiloid in their structure, and resembled No- NIONINA as figured by Ehrenberg in the Abhandlingen der Koniglichen Akademie der Wissenschaften zu Berlin, aus dan Jahre, 1839 : described as found living in the North Sea. Another species appeared to belong to ROTALIA, and still another species to UUINQUELOCULINA. They are all very minute, and can only be distinguished by a magnifying glass, perceptible to the naked eye as mere points or specks, when laid on some colored substance. The two nautiloid species are very beautiful as seen highly magnified, of a pearly lustre, and partially translucent.

A specimen now in the Society's collection was captured at the Forest River Lead Works in Salem, Aug. 9, 1845. It was observed in the act of feeding upon the barnacles (Balanus ovularis) which grew upon the wood work of the pier, and was noticed for some time before it was secured. It is a Southern species, and therefore a stranger to us. Its size is appended as follows, viz : Length 21 inches, depth across from base of the dorsal spine 8 1-2 inches. This dorsal spine is single, measuring two inches in length, ser- rated on the posterior edge, and forms a sort of armature. LEPTOCEPHALUS GRACILIS. STOKER in Proceed. Bost. Soc, Nat. Hist, vol. II. p. 70. Storer's Synopsis, p. 272. Through the kindness of George H. Devereux, the speci- men of this new and exceedingly rare little fish, was for- warded to the Society in the year 1845. It was taken at Cherryfield, Maine, from a basin formed in a timber raft ; and its occurrence introduced a new genus to the Ichthyo- logy of this continent. Its appearance is like that of a narrow piece of tape, ending in a somewhat acute point at the snout, and diminishing gradually in a similar way, to the end of the tail, which is however rather more blunt. It is also so thin that when alive it must have been transpa- rent. In Pennant's British zoology, vol. III. p. 212, pi. 28, mention is made of a species still rare in England, under the title of Leptocephalus Morrisii. The same is described and figured in London's Mag. of Nat. Hist. vol. 6. p. 531 ; and reference is made to four other specimens in the fifth vol. pp. 313. 742., occurring in Great Britain. The Cher- ryfield specimen is a distinct species, as shown by Dr. Storer in his observations, as quoted at the head of this paragraph. THYNNUS VULGARIS. Cuv. AND VALENC. Common Tu- ny. See Yarrell's British Fishes, vol. I. p. 134, and fig. Storer's Report of the fishes of Massachusetts, p. 47, &c. 121 Notices of several Fishes of Rare Occurrence. A specimen of this rare fish was found stranded on the flats of the North River, Salem, between the Railroad and Beverly bridges, Aug. 23, 1846. It is commonly known to us as the Horse Mackerel or Albicore ; but seldom seen in our waters and never noticed in shoals as in the Mediterra- nean Sea. The size of the specimen by measurement was found to be nine feet and six inches in length, and in girth seven feet, measured near the pectoral fins; which it is to be observed, exceeds the usual size as judging from those caught in the Mediterranean where they seldom exceed four feet in length, and frequently are not more than three feet long.

The attention, which the study of the lower tribes of marine and of molluscous animals have received within the last twelve years, since the issue of the second number, induces the attempt to furnish a list of the localities of those usually called shells, as well as the occurrence of other species of the same, not specified in the " Familiar Notice." In preparing the present paper, constant reference has been made to Dr. Gould's Report on *he Invertebrata of Massa- chusetts, published in 1841, to the several volumes of the Boston Journal of Natural History, to the Proceedings of the Boston Society of Natural History, and likewise to the " Shells of New England," by Win. Stimpson, 1851. The waters of the bay which wash the shores of our County have been dredged, the maws of fishes caught in deep water have been examined, and the various seaweeds driven on the beaches by winds have been carefully search- ed. The muddy bottoms of estuaries where fresh and salt waters combine, have been inspected, and our rocky hillsides and extensive ponds have received attention, by members of our Society and by others. The names of Dr. William Prescott, formerly of Lynn, of Dr. Henry Wheatland, of Salem, of Mr. Joseph True of Salem, of Messrs.

This beautiful native reptile first described and figured by Dr. Holbrook, in his North American Herpetology, will be found to be described under an incorrect name, viz: (Hyla femoralis, var. c.) See p. 93. The Genus Hylodes was separated from Hyla by Zitzenger, on account of the absence of a sternum (breastbone) as in the true Hyla. Dr. CHARLES PICKERING, formerly of this city, discovered it, in this vicinity, several years ago, and, as a new species, it has been dedicated to him ; a tribute of scientific respect. INDEX. Page.
