By Abthur Adams, P.L.S., &c. Received September 11, 1862. [Eeacl Nov. 6, 1862.] I HAVE not met with a single species of PyramideUa, s. str., in Japan. The small plicate species with a single plait, separated under the name of Fartlienia by Lowe, and the pupoid forms arranged by P. P. Carpenter under the head of ChrysalUda are the most numerous of the subfamily. Besides these, I recognize a thin, turreted form, which I call Pyrgulina ; an ovate-cancellate group, which is named Mumiola ; a plicate form, with a spiral axis, which is my Mormula ; and a little group, solid, and half costate, half lirate, which I designate Miralda.

E., Wal- lace in the Islands of Mysol, Ceram, Waigiou, Bouru and Timor. By Feedeeick: Smith, Assistant in the Zoological Department, British Museum. Communicated by W. W. Saundees, Esq., r.E.S. & L.S. [Read Jan. 15, 1863.] It will be observed, on comparing the contents of the present col- lection with others described in previous papers, that the species most widely distributed belong to the families Vespidoe and SpTie- gidce, both containing insects of powerful flight ; whilst among the apterous genera, or those in which the females are onl)'' tempora- rily winged, as in the Formicidcd, the range of distribution is much more circumscribed ; it is, consequently, here that the largest number of new species are foimd. In this paper, no less than four new species of the family Thyn- nidcB are described, one belonging to the genus ^hirus, the first, I believe, that has occurred out of Australia. We hope shortly to be enabled to draw up a set of tables showing the range of geo- graphical distribution of the numerous species of Hymenoptera described in the various previous papers on the insects of the Eastern Archipelago.

Antenn. intestines or internal organs at all seemed yet to have been formed, Tlie body was perfectly transparent and full of difterent-sized cells, which seemed a trifle more aggregated between the segments of the abdomen. In some there was no distinction between the head and thorax, or between the thorax and abdomen ; in others this distinction began to appear (whether visible on account of position or not I could scarcely say, but probably it might be so). On the skin being ruptured, the cells poured out in quantity, but there was no appearance of any vessels or defined internal structure of any kind. There was, however, an indication of the eye externally. I am therefore compelled to admit that, if my African specimens had been fresh and entire, I should have found a head and long legs curled up under the thorax, and not an apodous acephalous maggot. So much by way of rectification of the mistake which I myself have committed. It remains to consider whether Professor Owen's statement, which led me wrong, is correct or not. If his observa- tions bear the meaning which I attached to them, I certainly think he has fallen into a mistake. If he meant, as I supposed him to do, that the young Blatta ever was in the egg in the shape of a real acephalous and apodal larva, then I feel very confident that he is wrong ; and he may have been misled in one of two ways. He may have fallen into the same mistake which I committed — mistaken the vermiform-looking back of the Blatta for a maggot. Or he may have fallen into an error which I have escaped. In opening one of these egg-capsules (not taken from the parent in- sect, but one which had arrived at maturity, and been deposited), I found a number of the larvae in a disarranged, empty, sloppy state. 104 MR. A. MURRAY ON OETHOPTEROUS INSECTS. and in the midst of them a very comfortable, firm, plump, fat, true apodal and acephalous larva (fig. 3). It was obviously a parasite. Fig. 3. In the same capsule were found a large number of Chalcidites, some in chrysalis and some in the imago state. The apodous larva probably belonged to them. Professor Owen may have met with a similar parasite, and mistaken it for the real lord of the manor. This is on the supposition that I have rightly interpreted Pro- fessor Owen's views. It may be that I have misunderstood him. In speaking of the insect passing its larval stage in the egg, he may have merely meant its embryonic stage. If this was what he meant, then probably we are at one in our meaning ; for it has never occurred to me to question that, in its embryonic existence the Blaftci went through the usual course of development observed in other animals in which it has been studied. I perfectly believe (although I have myself never traced its progress) that, as in the Aphis, whose development from the egg has been so clearly fol- lowed out and described by Professor Huxley — and, for that matter^ as in the Vertebrata and in our ovni species — the first semblance of form which the germ of life assumes is a cord which may not inaptly be compared to something vermiform, and this shapeless shape or formless object gradually and imperceptibly assumes that shape which it is to bear when it leaves the egg. Consequently the long legs must at one time have been short ones, and still further back must have shown their first indications as buds. This is embryonic development ; and if it is this which Professor Owen means (and there are some passages in his work which now lead me to think that it may be so), then I misunderstood his mean- ing, and have been writing and thinking at cross purposes with him. But if that is his meaning, then I must dissent from the relation which he appears to think exists between the development of these insects in the egg and the metamorphoses of other insects out of MR.

By W. Cabmichabl M'Intosh, M.D., F.L.S. Communicated by T. S. CoBBOLD, M.D., F.L.S. [Eead Dec. 4, 1862.] The nature of the food of the Salmo salar has been variously esti- mated. Dr. EJiox read a paper to the Linnean Society " On the Food of certain gregarious Fishes," including the Salmon, in which it is stated*, " From the time the salmon enters the fresh water, it ceases to feed, properly speaking, although it may occa- sionally rise to a fly, or be tempted to attack a worm or minnow, in accordance seemingly with its original habits as a smolt. But after first descending to the ocean and tasting its marine food, it never again resorts to its infantile food as a constant source of nourishment." He goes on to state that nothing whatever is found in the stomach or intestines of the fresh sea-salmon but a little reddish substance, which he found to be the ova of some species of Echinodermata, and affirms that such is the sole food of the salmon in the sea. He combats the views of M. Valenciennes, who describes the salmon as voracious and a devourer of fishes, and * In abstract of paper, Annals of Nat. Hist., 2nd series, vol. xvi. p. 60. 146 DB. w. c. m'tsttosh ok the food and maintains tbat there is not a single fact in the history of British salmon to support this opinion, and concluding thus : — " As to their feeding regularly in rivers, Mr. Young's experiments have nega- tived the assertion beyond all doubt." Tarrell gives the authority of Paber to support the assertion that it feeds on small fishes and various small marine animals ; and Dr. Fleming says, " their favourite food in the sea is the sand-eel." Others confirm the latter statement, and add that within flood-mark some salmon have been taken with two, and some with three fuU-sized herrings in their stomachs. In order to test the accuracy of the above conclusions with regard to the Tay, I examined the stomachs and intestines of upwards of a hundred salmon and grilse caught in the river from the commencement of the season in February to its ending in September of this year. The salmon in its young condition feeds freely enough ; for the stomaclas and intestines of the parr from Stormontfield ponds are gorged to an extreme degree with beetles, flies, larvae, larvse-tubes, and minute Crustacea, while those of the smolts are also well filled. Indeed the voracity of young parr has cost them their lives in instances where they have been too freely fed with small flies. Such being the nature of the fish from its earliest age, one is sceptical at first sight in regard to the statement that the grilse and salmon do not feed in fresh water at all. Professor Owen* observes that the salmon, in common with many other fishes, when hooked or netted, empties its stomach by an instinctive act of fear, or to facilitate escape by lightening its load ; so that the stomach, thus cleared of its contents, exhibits subsequently, for reward to the investigator, only the tiny animal- cules, which, having been swallowed with more substantial fare, escaped ejection by lurking in the gastric mucus. "Were such the case, an explanation would be readily given to the fact that the stomach of a fish which possesses so powerful a circidatory appa- ratus, and whose mucalar tissues undergo a continual waste, should thus frequently be found empty. But if the salmon so fared, we should expect to find the intestines at least well filled with the debris of such food, since it cannot very easily vomit it after it has passed the pylorus ; and the very terror which impels it to dis- gorge in one case may entirely paralyse its efibrts to do so in another. In its usual condition, the stomach is coated internally with a consistent white mucus of great tenacity, well calculated to hold * Lect. on Comp. Anat. : Fishes, p. 237. I PAEASITES OF THE SALMON OF THE TAT. 147 any " animalcules " introduced from without ; yet in few or none did such occur, cellulo-grauular matter and oil-glohules alone appearing. In ten instances only did remnants of fishes occur, and in all these nothing remained but vertebral columns, cranial and other bones, with the denser tissues, as the lens, &c. The number of bones in several cases showed that the animals had en- joyed a most ample repast, since they belonged to fishes from 8 to 10 inches in length — of what species I have not been as yet able to determine. Some pieces of cartilage, skin, and pigment-cells seemed to belong to smelts, but most of the vertebrae belonged to larger fishes. The other kinds of food found in the stomach con- sisted of fragments of small freshwater Crustacea with a portion of a shrimp in one or two fishes, and an occasional piece of in- sect-cuticle. The duodenum is generally supplied in abundance with a less cohesive mucus of an orange tinge, and which is continued along the intestine. A constant accompaniment of this mucus in almost all fishes is a number of whitish or yellowish masses, extending far down the gut as a fragile knotted cord surrounded by the mucus — in some instances nearly to the anus. When a small portion of the white substance is put between glasses, it is gritty, and is found to consist of a vast number of calcareous crystals like those of the triple phosphate. They are quite unaflected by ether, but effervesce much and disappear on the addition of hydrochloric acid. Some of the larger crystals showed roughnesses on their svu-faces, as if smaller crystals adhered or had adhered to form com- pound masses ; others had a somewhat radiate arrangement of the constituent crystals. They occiu'red in all portions of the intes- tine from the pylorus downwards, but not in the pyloric caeca, and appeared in the fasting as well as in the full-fed fish. The mucus which more immediately surrounded them had a fibro-granular aspect. The exact origin of these crystals is an interesting ques- tion. So constantly were they present imder all conditions as regards food, that they could not have been much influenced by the varying state of the latter. The intestinal surface being an eliminating as well as a secreting surface, we may conclude that these crystals had their origin in fluids produced by the mucous membrane. The skeleton of this fish being of small specific gra- vity and deficient in earthy matter, it may be that the excessive elimination of salts keeps down the specific gravity ; or again, the circulating fluid by this means may so adapt the bones to the varying density of the salt and fresh water that their specific 148 DB. W. C. M'INTOSII on the rOOD AND gravity is in accordance witli the medium. At any rate, and whatever be the explanation, the presence of these crystals is an interesting physiological fact. In a greater number of instances than in the case of the stomach, bones, lenses, and other dense textvires occurred in the intestines ; for they were present in several instances where no trace occurred in the former, and vertebrae could readily be detected as far down as the anus. In addition to those in which the debris of ascertained food in the stomach was found in the intestines, I met with crustacean hairs in several instances, Diatomacese, sand-particles, fragments of an insect, masses of solid fat, and portions of liver belonging to a fish like the Sparling. In every other instance there was nothing in the intestinal tract but parasites, mucus, crystals, and an abundant supply of fatty globules and particles of all sizes. The rapidity and power of digestion in this fish is extraordinary ; but there is no doubt that, if the fish had fed regiJarly, the food could never have disappeared so rapidly and well as to defy even a microscopic investigation of the intestinal tract throughout. It is, however, a mistake to suppose that they never feed in fresh water at all, just as it is one to suppose that they feed voraciously, but vomit their food when captured. The true state of matters would seem to be that the salmon when in fresh water feeds rarely and at intervals, but not from want of voracity, as the contents of the stomachs above mentioned show ; and further, that such food is occasionally found in its stomach from February till August *. Ectozoa. — I had only the opportunity of examining about a dozen grilse and salmon for these parasitic animals, and the sole species foun^ within the period above mentioned was Lepeoph- theirus Stromii (Baird) — four males and three females. They occurred at the base of the fatty fin, at the base of the caudal rays, in the socket of the eye, and in front of the hyoid apparatus — and all in grilse. Nothing whatever occurred on the branchiae to attract attention but once ; and this abnormal appearance proved to be non-parasitic. A number of large villi proceeded from a bulging and thickening of the arch, but solely attached to the cutaneous textures. The villi or processes were fibro-cellular in structure, and contained at their bases numerous black pigment-corpuscles and crystalline masses. They seemed to be morbid growths of the fibrous textures of the region. * They have also been seen to void several vertebrae per anum, when landed on the bank of the river. PARASITES OF THE SALMON OE THE TAY. 149 Entozoa. — If tlie search for food in the digestive system of the clean sahnon and grilse was only rarely rewarded by success, certainly tliat for entozoa was more fortunate. There was scarcely a single fish which did not contain some of the following species, and many had them in abundance. The first of these I shall de- scribe (fig. 1, a, h) is seldom or never absent throughout the entire Kg. 1. series of grilse and salmon. It is a minute creature, of grega- riniform aspect, which squeezes its gelatinous body hither and thither amongst the granular debris and oil-globules of the duo- denum and pyloric cseca. In its interior are numerous globules and granules, and a larger spherical body, wliich, when the animal is flattened between the glasses, gives it the aspect of having a sucker. One end is generally darker from the accumulation of the granular contents. Besides the shapes depicted in the draw- ing, this creature very often assumes an hourglass aspect from a central constriction. One of the chief habitats of this gregarini- form animal is the pyloric CEeca, where it has been found amongst the dry mucus even at the tip of one entirely blocked up by the coils of a Bothriocephalus. It is in all probability a stage in the development of some higher parasitic form. Occurring in the greater number of the specimens of both grilse and salmon is Distovia varicum (Rud.), {Fasciola varica O.F. Miiller, Zoologia Danica, p. 43, plate 72). Almost with- out exception, this species occurred in the stomach of the salmon, imbedded amongst the tenacious mucus, or else at the border of the latter at the commencement of the organ. They varied in number from one or two up to twenty -five or thirty in extreme cases, and they were also diversified as regards size. Miiller in the above work observes that he met with five in the stomach of a salmon, and Eudolj^hi states that it is rare. This, 150 DE. w. c. m'intosii on the food and as above mentioned, is not the case with the salmon from the Tay, in which this parasite is rarely wanting. The description of the foregoing authors leaves little to be added, further than that Ru- dolphi is correct in stating that there is no anus as described by Miiller. Detached and solitary ova frequently occurred in all por- tions of the intestine and caeca. In some specimens, bodies that seemed to be spermatozoa-cells were seen, in constant motion within tubes. When the Distomata are put into water, they wriggle and lengthen themselves, and the ventral disc may be seen occa- sionally tinged with blood. In the duodenum ©f one fish was a remarkable Distoma, which appeared rather to be two in con- gress, but yet may be a malformation, since one oral sucker only could be found, and each half diifered somewhat from the body of an ordinary Distoma. A single specimen only of another species of Distoma {D. tere- ticolle), of an elongated form, occurred in the intestine of a salmon. In the oesophagus of a salmon a peculiar flask-shaped body was met with. It equalled in size a full-grown Distoma varicum, was of a yellow colour, and possessed two dark-brown patches, one at the broad end, and the other an elongated lateral one. The general body of the structure was filled with cells and granules, while the dark patches were made up of the dark-brown cells or masses, and some of the latter were of an elongated form. The contained pale cells and granules floated readily out through any fissure. Whether it is a parasitic structure pertaining to the salmon or some other fish I am unable to state, farther than that it once occurred in the stomach of the former. I found a single specimen of TetrarhyncTius appendiculatus (Hud.) when washing the mucous surface of the stomach of a sal- mon. On this there was a little eminence having a minute aper- ture at the summit, which when pressed gave exit to a small white body — after the manner of the parasites of the human skin, and the part extruded was the posterior elongated body shown in the figure *. When a section divided the eminence, the creature firmly adhered by its anterior hooks. On removal, it progressed leech-fashion by successive waves of its soft white body, adhering by either end at pleasure. The anterior or larger portion of the body was intensely white, the posterior appendage less so. When moving, its body assumed various shapes, now like a thick round jar, or again like an elongated flask, with numerous longitudinal striae on its external surface. The body of the Tetrarhyuchus was * Eudolphi, tab. 7. fig. 10. PARASITES OF THE SALMON OF THE TAT. 151 enveloped in a tougli white investment, and appeared one mass of cells of an elliptical form — some with and some without nuclei. Fibrous and muscular bauds and peculiar tubes stretched back- wards from the spinigerous columns. Some of the tubes were filled with cells ; others, probably from bursting, were empty. Anteriorly it was armed by the four formidable spinigerous processes capable of protrusion and retraction. Each consisted of an elongated and somewhat tapered stalk covered with a com- plete array of curved spines resembling on a miniature scale those on the rose, viz. with a broad base and strongly curved sharp point. They were regularly arranged on the column, and towards the base showed an interesting gradation into short, closely grouped blimt tubercles, not unlike the horny scales on the foot of a land tortoise. Below this the spinigerous column was marked by a constriction followed by a slight bulgiug, and ran inwards in the shape of a tubular process connected with a curved elongated sac. The sac was covered with an immense number of cross striae as well as longitudinal furrows. Prom the opposite end of the sac, the tube was continued into the general body of the animal, and became filled with the oval cells and granular matter every- where so prevalent. On the addition of acetic acid, immediate effervescence resulted in certain opaque and translucent masses ux the interior of the animal ; and the numerous cells formerly so conspicuous became transparent and indistiuct, or were broken up into smaller cells. Once afterwards the scolex of a species of TetrarhyncJius (fig. 2, a) occurred in the rectum of a salmon. It contained the usual Fig. 2. small, smooth, oval bodies or cells, quite pale and translucent {b). Under the action of dilute glycerine and pressure they assumed the shapes (e) aloug with some of the other contents of the scolex. Three or four specimens of Echinorhynclius inflatus (Rud.) oc- curred in the intestines.

The more perfect one had its head retracted and quite loose. The entire animal was about half an inch in length. Continuous with the base of the proboscis was an elongated muscular structure, possessing many longitudinal striae. Attached to this were many muscular bands slanting backwards. In the space behind the sac were also many cellular, granular, and crystalline masses. Rather behind the middle of the animal were two elliptical testes, granular and opaque. Posterior to these lay the ordinary granular and cellular structures, besides a convoluted tubular organ, at whose termination was an ovoid mass with a coiled aspect. This was succeeded by a peculiarly convoluted structure shaped somewhat like tlie semicircular canals of the in- ternal ear, and followed posteriorly by a barred curved portion which lies a little in front of the termination of the animal*. The investing structure formed a thick layer, marked here and there by many mottled and shaded portions. When the hooks of the creature are fixed in the mucous membrane, it is impossible to remove them without tearing the texture therewith, as may be readily imagiued from their form and direction. Bothriocephalus prohoscideus (End.) was the only species met with ; but it occurred in by far the greater majority of the grilse and salmon, generally commencing with its coils in the duodenum and pyloric caeca, and stretching down the gut. The heads were generally met with in one of the caeca ; and the appearance of the various specimens was very similar, except that some (probably owing to peculiarity of pressure) showed a greater bulging of the outliae just behind the anterior end. The following may be given as transformations in its passage fi-om the embryonic to the adult condition, — the embryo bearing a relation to the fully- developed wonn similar to that which Pluteus and Pilidium respectively bear to Ophiurus and Nemertes. Dr. Guide Wagener's previous investigations had led us to believe in a more simple and direct mode of development (Siebold and KoUiker's Zeitschrift, 1857, vol. ix. p. 77) ; but Leuckart fully estabhshes the fact of a true alternate generation in the hfe-history of Eehinorliynchus.

In a salmon of ten pounds, a BothriocepLalus lay coiled in tlie duodenum, and passing down to the small intes- tine filled it even to distention. The anterioi' portion proceeded into a caecum by a double coil ; from this, other four plies (two coils) entered another caecum close by the pylorus, and performed many intricate bends therein, filling out the sac to a size equal to the similarly distended intestine of the fish. This csecum contained the head, the distance of which from the trimcated posterior ex- tremity was 6 feet 6 inches. About 20 inches from the head a narrowing of the segments occurred, so as to resemble those near the head, — a not unfrequent occurrence. The size of the ]3othrio- cephali did not always bear comparison with that of the fish. Ascaris capsularia (Eud.). — This species is easily recognized by a whitish opaque portion a little behind the head. It is found on the liver, pyloric caeca, stomach, intestines, and gall-bladder at the attachment of the mesentery, &c. It is enveloped in a cap- sule of delicate fibrous tissue, in which it lies as a finger in a glove, — a circumstance which, from the attachment of the capsule to the surrounding textures by many delicate fibrous bands, renders it difficult to pull the creature ofi" rudely or en masse, while it can readily be unhoused by dravraig at its free end. These Ascari occur in most grilse and salmon ; in fact, it is exceptional to find them absent. On the liver they are met with on all parts of the surface, coiled in a circular depression of its texture, but with a portion of the latter projecting in the centre. Most form this close coil, but others stretch in a long curve or semicircle. In the former the head is always external. On the caeca they are found amongst the iat, coiled after the fashion of a nummulite, and often sur- rounded by a deposit of pigment. Occasionally one had the an- terior part of the body pushed into a caecum, or, rarely, into the tissue of the liver. Once, on examining a small eminence on the inner surface of the stomach, a living Ascaris capsularia emerged on squeezing the perforated sunjmit. Earely one or two occurred in the interior of the stomach and intestines. Attached to the pyloric caeca, where these are so frequently found, curious struc- tirres which seemed degenerated Ascari were sometimes met with. A calcareous deposit filled part of the interior of one example. Other forms of Ascarides * were present, some of which appeared referable to undescribed species. It may also be noted that in the stomach I once met with several small fibro-cartilaginous * One species especially occurred veiy frequently,, 154 MR.

These portions are denser than the ordinary mucous surface, and often slightly ele- vated. Under the microscope they are fibro-granular. It is pro- bable that they originate in some former parasitic inroads. A succinct Eeview of recent Attempts to explain several remark- able Tacts in the Physiology of Spiders and Insects. By John Blackwall, P.L.S. [Read AprU 2, 1863.] My friend Mr. Meade, in his valuable report " On some Points in the Anatomy of the Araneidea, or true Spiders, especially on the internal structure of their Spinning Organs," * has been induced by his researches to adopt the opinion that these animals can propel from their spinners, to a considerable distance, fine lines formed of the viscid fluid secreted by appropriate organs situated in the interior of their abdomen. This hypothesis, based on zoo- tomical considerations, being directly opposed to the conclusion arrived at by myself from numerous carefully conducted experi- ments, merits an impartial examination. After having briefly stated the general results obtained by his dissection of several species of spiders, and minutely described the organization of the internal vessels that elaborate the material which, on issuing from the papillae connected with the spinners, forms filaments of extreme tenuity, Mr. Meade remarks, " I have now arrived at the most interesting but most difficult part of my task, viz. the question whether there is anything in the structure of the silk -forming organs that will decide the question as to the power of spiders to eject their threads to a distance. Looking at the strong fibrous coat on the ducts of the membranous sacs, and the fibrous tissue surrounding the glands themselves, I think that they must possess a powerful contractile power, which may also be increased by the muscular coat of the integument enabling the spider to compress its abdomen. May not the striated bands of muscular fibres, which run in a parallel direction down the middle of the abdomen quite into the interior of the spinnerets, and surround the termination of the ducts, also assist in this ob- iect ? They are not attached to the tegumentary coverings of the spinnerets like the other muscles, and cannot therefore be for the * Keport of the Twenty-eiglith Meeting of the British Association for the Advancement of Science, p. 157. IN THE PITTSIOLOOT OF SriDERS AND INSECTS. 155 purpose of moving these processes ; their action must be to draw the spinnerets inwards." Such is the evidence supplied by dissec- tion in support of the opinion that spiders can forcibly eject their lines to a distance. Now it is manifest from well-known physiological facts that the muscles distributed to the spinning-organs perform various func- tions, the office of some being to give motion to those parts, of others to close either the minute aperture in the dilated base of the tubular papillae, or that of the fine ducts which terminate the vessels that secrete the fluid employed by spiders in the process of spinning, as its issue from the papillae can be instantaneously prevented at the will of the animals ; others, moreover, must pos- sess a contractile force sufficient to propel the fluid to the open extremity of the delicate hair-like papillae, exactly as the non- viscid fluid, propelled by the contraction of the muscles connected with the vessel that secretes it, passes out of, but is not ejected in a stream from, the minute orifice situated near the extremity of the fang that terminates the falces. To this extent I am prepared to admit the influence of the muscles that contribute directly or indirectly to the action of the spinning apparatus ; but that a remarkably viscid fluid, which immediately becomes concrete on exposure to the air when drawn out in a filament of such marvellous tenuity as the lines produced by spiders, can, notwithstanding its extreme levity and flexibility, and quite irrespective of the size of the animals producing it, be propelled by any physical power vdth which they are endowed in a straight line of many feet in length, through a resisting me- dium liable to rapid fluctuations like the atmosphere, does appear to be in the highest degree improbable, and is, as already asserted, directly at variance with the result of an extensive and elaborate experimental investigation of the subject*, a brief abstract of which I proceed to give. Spiders, if placed on wooden or metallic rods set upright in glass vessels with perpendicular sides, containing a sufficient quan- tity of clean water completely to immerse their bases, in vain attempt to effect an escape from them in a still atmosphere ; all their efforts to accomplish the desired object, though perseveringly persisted in, proving quite unavailing when they are placed under a glass-shade, or in any situation where the air is not liable to be * Transactions of the Linnean Society, vol. xv. p. 455 ; Researches in Zoology, pp. 242-248 ; A History of the Spiders of Great Britain and Ireland, part 1st, p. 12. 156 MR. J. BLACKWALL ON SOME REMARKABLE EACTS disturbed. However, should individuals thus insulated be ex- posed to a current of air, either naturally or artificially produced, they instantly turn the abdomen in the direction of the breeze, and emit from the spinners a little of their viscid secretion, which, being carried out in a line by the current, becomes connected with some object in the vicinity, and affords them the means of regain- ing their liberty. This line uniformly moves in the direction and with the velocity of the stream of air ; but if, while proceeding from the spinners, it be subjected to the action of a lateral or opposing current, it immediately becomes deflected from its course by the new impulse thus imparted to it. I may here remark that numerous species belonging to various genera of spiders, — Drassus ater, Cinijlo similis, Ergatis latenSy Tegenaria civilis, Ccelotes saxatilis, Dysdera erythrina, and Oonops pulclier, for example, — though provided with highly organized spin- ners, yet do not appear to be endowed with the instinct to avail themselves of a current of air for the purpose of transmitting their lines to a distance. The manner in which the lines of spiders are drawn out from the spinners by a current of air admits of an easy explanation. As a preparatory measure, the extremities of the spinners are brought into contact, and viscid matter is emitted from the pa- pillae ; they are then separated by a lateral motion, which extends the viscid matter into filaments connecting the papillae ; on these filaments the current impinges, drawing them out to a length which is regulated by the will of the animal, and on the ex- tremities of the spinners being again brought together, the fila- ments coalesce and form one compound line. The only legitimate deduction from the foregoing experiments, which have been frequently repeated under every variety of cir- cumstances likely to aifect the result, ajipears to be that the lines produced by spiders are not propelled from the spinners by any physical power possessed by those animals, but that they are in- variably drawn from them by the mechanical action of external forces. § 2. The importance of the greatly diversified form of the remark- able organs connected with the radial and digital joints of the palpi of male spiders, in affording valuable specific characters in numerous cases in which species so closely resemble each other in size, colour, and economy as scarcely to be distinguished except by miiiute differences in their external structure, is beginning to IN THE PHTSIOLOOY OF SPIDERS AND INSECTS. 157 ue duly appreciated by arachnologists, whose attention hitherto has been abnost exclusively directed to investigations having for their object the discovery of the function performed by those organs — a highly interesting pi'oblem undoubtedly, the solution of which long continued to exercise the skill aud ingenuity of zoo- tomists and physiologists. Though the palpal appendages are now known to have a strictly sexual character, and have, in fact, been demonstrated by experiment to constitute a true intromittent organ absolutely essential to fecundation *, yet no direct commu- nication has been ascertained to exist between them and certain vermicular vessels situated in the abdomen, and usually regarded as testes, whose ducts terminate in the space intermediate between the branchial stigmata. M. Duges has attempted to obviate this difficulty by shrewdly suggesting that these parts may have been voluntarily brought together prior to the act of copulation, and then proceeds to ask, "le conjoncture" (palpal organ) " ferait-il alternativement 1' office de siphon absorbant et d'organe ejacula- teur?" — a question which he answers in the following terms : — " cela se pent, mais je n'ai rien pu observer, qui justifiat directe- ment cette conjectiire." f In a concise notice of a work on the habits of the Araclinida, by A. Menge, given in the ' Reports on Zoology,' for 1843 & 1844, p. 195, published by the Eay Society, the following passage occurs : — " Copulation. It was reserved for the author to solve the physio- logical enigma which this act had hitherto presented. The spoon- shaped palpi of the males are in fact the copulative organs, with which they take the semen from the appropriate openings of the seminal ducts on the base of the abdomen, and transfer it to the sexual opening of the female. The procedure is carefully de- scribed in various Spiders," Not having had an opportunity of perusing the work of M. Menge, I am unable to state the par- ticular observations which have led to a conclusion so precisely in accordance with the supposition previously entertained by M. Duges, This view of the subject I am incompetent either to confirm or refute, as in the course of extensive and minute investigations I have not succeeded in observing the act above described ; and yet * Researches in Zoology, pp. 295-298 ; Report of the Fourteenth Meeting of the British Association for the Advancement of Science, pp. 67-69. t Anuales des Sciences Naturelles, 2de serie, Zoologie, tome vi. pp. 189, 190. LINN. PROC. — ZOOLOGY, VOL. Yll, 13 158 ME. J. BLACKWALL OK SOME BEMARKABLE FACTS in numerous cases it ought to be very apparent, as the shortness of the palpi would render a strong inilection of the cephalothorax towards tlie inferior surface of the abdomen absolutely requisite before they coukl be applied to the part indicated as the seat of the seminal ducts. I shall conclude these remarks with the statement of a few facts bearing upon the question, which have come to my knowledge in pursuing researches relative to the generation of Spiders. In the act of copulation, the extremity of the organ of each palpus of the male, in a state of tumefaction, is usually introduced alternately into the vulva of the female, and that many times in succession, without being once brought into contact with any part of its own abdomen, though it is very frequently conveyed to the mouth ; and I have observed a male Lycosa lugubris apply its right palpus eighty times, in the manner above described, to the vulva of a female (both of which had been placed in a clean glass phial), without the possibility of bringing it into contact with the inferior surface of its abdomen, except by a very conspicuous change of position ; and as an equal number of similar acts were performed by the left palpus, we have the extraordinary fact of the palpal organs being employed 160 times during this greatly protracted process, unaccompanied by any contact whatever with the part where the seminal ducts are considered to terminate. A male Agelena lahyrintliica, confined in a phial, spun a small web, and among the lines of which it was composed I perceived that a drop of white milk-like fluid was suspended ; how it had been deposited there I cannot explain, but I observed that the Spider, by the alternate application of its palpal organs, speedily imbibed the whole of it. Perhaps the only safe conclusion to be drawn from this very remarkable circumstance, taken in connexion with the previously well-ascertained ofiice of these parts, is that it affords a complete answer in the affirmative to the question asked by M. Duges, namely, " le conjoncture ferait-il alternativc- ment I'office de siphon absorbant et d'organe ejaculateur ?" § 3. My explanation of the means whereby various animals are sup- ported in their movements on the vertical surfaces of liighly- polished bodies having recently been called in question,'! am in- duced to offer a few remarks in vindication of its accuracy. Mr. Tiiften West, in treating " On certain Appendages to the IN THE PUTSIOLOGY Or SPIDKKS AND INSECTS. 159 Feet of Insects subservient to Holding or Climbing"* advocates the hypotliesis that the papillae distributed over the inferior sur- face of the pul villi of flies and other species of the class Insecta act separately as independent suckers, adhesion being assisted by the emission from each of a small quantity of fluid. This view of the subject, being absolutely irreconcilable with the results of observations and experiments regarded as having established a widely different conclusion, I am not prepared to adopt. That fluid is emitted from the papilla3 connected with the pulvilli of the House-fly and Flesh-fly when in motion is unquestionable, as finely pulverized nitrate of silver brought into contact with those parts is immediately acted upon by it ; but that its agency is merely to effect a more complete vacuum between the climbing apparatus and the plane of position is evidently inadmissible. This fluid, which appears to possess a moderate degree of viscidity, assumes a gelatinous consistency when coagulated by exposure to the atmosphere, and by its adhesive property enables animals pro- vided with the requisite organs to move with facility and security on the vertical surfaces of dry, highly polished bodies. In confir- mation of the explanation of the phenomenon here insisted on, many facts might be advanced ; but it will suffice, in the present instance, to direct attention to one, the decisive character of which cannot be mistaken. That flies are not supported on the vertical sides of highly- polished bodies by the pressure of the atmosphere, experiments with the air-pump plainly demonstrate ; for they can not only tra- verse the upright sides and the interior of the dome of an exhausted receiver, while their physical energy is unimpaired, but individuals occasionally remain fixed to the sides of the glass after they have entirely lost the power of locomotion — a circumstance which can only be explained by admitting the adhesive property of the fluid emitted from the extremity of the papillae on the inferior surface of their pulvilli. To the same cause must also be attributed the power of Spiders that are provided with scopulse or tarsal brushes to run with celerity on the vertical surfaces of highly polished bodies, as those instruments consist of numerous appendages slightly curved downwards and somewhat enlarged towards their extremity, which is densely covered on its inferior surface with minute hair- like papillae for the emission of a viscid fluid, but which, from * Journal of the Proceedings of the Linnean Society, vol. ri. p. 26. 13* 160 MR. F. WALKER ON HETEROCEROTJS LEPTDOPTERA their organization, cannot possibly contribute to the formation of a vacuum. The foregoing solution of this interesting physiological problem, I have reason to believe is applicable not to insects and Spiders alone, but also to some species of reptiles.

On the Species of Mitridce found in the Seas of Japan. By Aethue Adams, E.L.S., &c. [Kead Dec. 3, 1863.] The shores of the Japanese Islands which are washed by the Pacific are most prolific in species of Mitridcs. Towards the north, in the Sea of Japan, I met with no member of the family. A few new species are here described, and a systematic list of all the species which were actually obtained by me in those seas is given. Fam. MITEIDJS. A. MlTBIN^. 1. MiTEA, Lam. 1.
