¢ °7” whereas the next largest is only just °95” % °67”, I have never seen this bird in as large flocks as those in which C. aurifrons assembles, Asa rule, nob more than five or six are seen together, and often they are found in pairs. They do not, either, descend as low as C. aurifrons does. I have never heard of their being found quite in the plains, and only once or twice have I met with them anywhere below some 600 feet. Although they are very nearly entirely insectivorous, they are not altogether so, and in a caged state accustom themselves to a wholly vegetable diet. I have seen them two or three times, when wild, eating berries, and one I once shot in my compound had its stomach full of oranges about the size of a No. 4 shot. This bird and its mate lived in my compound, and did a good deal of damage to the one orange tree they particularly fancied. At first I flattered myself that they were destroying the red ants which infested the tree, but I soon discovered my mistake and did my best to drive them away, finally having to shoot one, that being the only way of ridding myself of their company. In captivity they seem to thrive on plantains and similar food, though they are grateful for any insects which may be offered to them, and more especially for any grasshoppers. A great friend of mine in Silchar had one of these birds in a cage, which was a most charming pet. It soon got to know that certain people gave it grass- hoppers or other dainties, and would become most excited whenever they came into the verandah, coming to the side of its cage and calling loudly to attract their attention. When J last saw it, it was beginning to sing, but had not come to its full powers, though it possessed, even then, a very sweet and musical littlesong. This bird had a habit of turning complete somersaults from off the top perch of its cage on to one of the lower ones, and this it would do some half-dozen, or even more, times in rapid succession. ‘This trick, however, is one which is common to the species—and, I believe, to the genus— and. in a wild state they may occassionally be seen indulging in these acrobatic feats. In turning these somersaults, the bird does not appear to apen its wing in the least ; it suddenly turns round on its perch, and drops, with closed wings, on to the place it desires to reach, either seizing something edible as it first turns round, or else directly after arriving on the lower twig. _ 14 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Voi, VIII. It is not nearly so quarrelsome a bird as its cousin already described, but it is quite as bold and plucky, and seems to be even a more finished fighter, for, as I have mentioned before, C. aurifrons does not care about attacking this bird, and gets the worst of it when he does. The song is the fullest and most prolonged, as well as by far the sweetest, of any bird of this genus, and it shares with the other members of it the wide variety of notes and wonderful power of mimicry. T have one female of this bird, which, however, is not an adult, which measures as follows :— Length °7”; tail 2°8”; wing 3°5”, This is the bird whose measurements I gave in the Asian; but now, with my greater experience of the species, I think that these figures are abnormally small, or that the bird would have become slightly larger with increased age.

They were shot at Gunjong, in January, 1891, feeding on a very high cotton tree. I know of nothing in their habits differing from those of the other members of the genus. THE BULBULS OF NORTH CACHAR. 15 The male several times uttered a cry exactly like one of the lower notes of the large Racket-tailed Drongo-shrike, and for some moments I thought that it was one of these birds calling, nor did I find out my mistake, until I shot the bird which uttered it and saw that there were no others in the tree. CHLOROPSIS JERDONI. JERDON 'S CHLOROPSIS. Phyllornis jerdoni, Jerdon’s “ B. of I.,” Vol. IL., p. 97 ; Hume’s Cat., No. 463 ; Chloropsis jerdoni, Oates’ “ Fauna of B. I., Birds,” Wolk Wy p. 238); zd., Hume's “ Nests and Hegs,” Vol. I., p. loo (2nd Hd.). Description.— Hale.—Whole visible plumage, with the exceptions noted below, bright grass-green, paler below and brightest on the head, rump, and upper tail-coverts ; shoulder-patch, formed by the lesser wing-coverts, bright smalt-blue, moustachial streak bright purplish-blue or ultramarine, chin and throat, lores, and over the moustache, black surrounded by yellowish, com- mencing from the forehead and continuing through the eyes downwards. The female has no black, and the moustachial streak is paler and inclined to greenish-blue. The young are wholly green. Nipirication.—If I confine my notes on this subject to those nests taken in North Cachar, I can give practically no information beyond what is already known, for, most undoubtedly, the bird is not an inhabitant of these hills, and the few which have been seen are only the progeny of tame birds let loose. As far as I can ascertain, the original birds, some three or four, were brought up to Gunjong by some sepoys in, or about, the year 1883, and released when the sepoys left the stockade. The first bird I ever saw was shot by Mr. Hughes, of the Frontier Police, at Gunjong, and two more birds were obtained by me that same year. In 1886 I found a nest containing three eggs, and this is the only one I have actually taken in North Cachar itself. It was just like those described as belonging to C. aurifrons, and was built in a small tree quite close to the cotton tree, on which the first bird was shot. The whole of my eggs, including the three found in Gunjong, average *91” X60", but I have only had a very small series pass through my hands, and out of this series two pairs were abnormally large, the four eggs measuring between *1” and 1:06” in length and ‘68” and °7” in. breadth, Deducting these four eggs, the remaining nine average only °86” x °58” even narrower than the dimensions given by Oates (vide “Nests and Eggs”). 16 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol, VIIT. A pair of eggs which I took in Nuddea has not been included in these measurements. Tn captivity this species also seems to be fed by natives principally on a vegetable diet, and it appears to thrive on this; but I have noticed—it may be only fancy—that birds fed thus are duller in colour than those fed on a meat or insect diet. Such is certainly the case with O. hardwickii, the blue parts beng duller and the green the same, and, moreover, tinged with blue, much as is the case with caged green magpies (Cissa sinensis). The first bird of this species I ever saw in captivity belonged to one of my servants, and I have never seen one as tame since. As it was allowed to fly about without restraint, it naturally gave free vent to its appetite for insects, and thus retained its proper coloration ; but at the same time it by no means despised plantains, and when shut up, as it sometimes was, ate them freely, I was told by the servants that this bird caught and devoured wasps and hees, but could get none at the time to test the truth of the assertion, and shortly afterwards the bird died a violent death. This habit of catching wasps may have been copied from a tame Racket-tailed Drongo (Dissemurus yaradiseus) which shared with it its semi-imprisonment. It was remarkably noticeable how the small bulbul “bossed” its much larger companion who, had he wished, could have easily killed him, As a rule, they got on very well together, but the bulbul was very jealous and resented any attention being shown to the shrike. I am much afraid that this bird, like I/yiophoneus temminckit, has died out, for, since 1890, I have not seen a single bird, of course, amongst the many C. aurifrons that I am constantly seeing, it is quite possible that I may over- look one or two birds of this species, and it is to be hoped that such may be the case. 17 LES FORMICIDES DE L’EMPIRE DES INDES ET DE CHY LAN.

Hindwing with the usual linear black markings in the cell; a discal series of six small obscure black spots, followed by a broad submarginal pure white band crossed by the black veins, decreasing in width at either end, bounded anteriorly and posteriorly by a narrow metallic green line, both lines increasing in width towards the abdominal margin where they meet in a poit, the anterior line through four interspaces divided from the broad submarginal white band by narrow lunules of the ground-colour ; abdomthal margin broadly pale fuscous. Cilia of both wings very narrow, white. UNDERSIDE, forewing reddish-brown ; the discoidal black markings very prominent; a discal irregular lunulated black band; a slightly curved submarginal series of six increasing round black spots ; the apex and outer margin decreasingly pale violet. Hindwing pale violet, the — outer margin fuscous; the white submarginal band as above, inwardly bounded by a series of round black spots between the veins, the innermost spots linear, recurved to the abdominal margin; followed by a series of four linear black spots from the third median nervule to the submedian nervure; then an angulate series of eight spots extending right across the disc of the wing, the discoidal cell and the base marked with numerous black spots. Nearest to Zanaécia nicéviller, Distant, from Perak, the type and two males of which I am able to compare with 7’. elone, differing conspicuously on the upperside of the forewing in having a very small metallic green area at the anal angle instead of a large blue area, and on the hindwing in having a large submarginal pure white band defined on both sides by metallic green, and not reaching the outer margin, not bearing a series of black spots at its middle, instead of a much broader blue band extending right up to the outer margin, On the underside of the hindwing the black macular markings are very well marked and prominent, much more so than in 7’. nicevillez, and the white band is again a conspicuous differential character. 7. zichri, Butler, from Sarawak (Borneo) and Malacca, appears to be another allied but quite distinct species. Can the genus Zanaécia be retained as a full genus? As ab present under- stood it contains a very heterogeneous collection of euthaliad butterflies ; but, as Mr. Doherty has pointed out,* the one character by which I once thought it could be separated from Huthalia, viz., by the anastomosis of the first subcostal nervule with the costal nervure of the forewing, has been shown by him to be utterly inconstant, even in the same species, and there appears to be, therefore, no other generic character left, unless the slender bristle-like terminal joint to the palpi be considered of sufficient generic significance, but, as far as my col- lection goes, only 7’. pulasara, Moore, which is the type of Zenaécia, T. aruna, Feder, and 7’. martigena, Weymer, possess this feature, all the other so-called * Jour.

Nearest to C. risa, Doubleday and Hewitson, which occurs from Kumaon — to Assam, in Burma, and again in Java, but not in the Malay Peninsula ; differs therefrom in the male in its darker ground-colour, the two basal pairs of lines on the upperside being filled in with fuscous, the discal single line being much broader, and especially in the absence of all violet markings in the space enclosed by the submarginal pair of lines, this being a very conspicuous feature in C. risa. In the hindwing of C. cyanee these purple markings are replaced by a broad black line ; also in C. risa there is always a more or less conspicuous series of pale yellow triangular markings in both wings, but more especially in the hindwing, placed internally to the inner of the two submar- ginal lines, which is quite absent in C. cyanee.

In the ground-colour of the upperside, A. ata resembles A. neophron, Hewitson, but the two whitish bands of the forewing ally it more nearly to A, savitri, Felder, which also occurs in Sumatra.

Nearest to D. singhapura, Wallace*, known to me by the figure and descrip- tion only, from Singapore and Borneo, differs in its smaller size, that species being 3°12 inches in alar expanse, the forewing rounded, not conspicuously elongated, and with the apex rounded, not highly pointed ; on the underside of the fore- wing the veins—-especially the median nervure—are less broadly defined with black, the marginal spots are smaller and only five, instead of six, in number ; on the hindwing the outer black border is narrower, less deeply black, the spots smaller, less distinct, entire, not divided by the internervular folds, five instead of six in number, the uppermost one of D. singhapura in the upper subcostal interspace being wholly wanting.

Forewing with two white spots at the end of the discoidal cell defining the disco-cellular nervules ; a submarginal series of seven oval whitish spots placed between the veins. Hindwing bearing a large, anteriorly white powdered with dusky, posteriorly pale primrose-yellow, area divided by the veins, occupying the outer end of the cell, this area is bounded outwardly by a broad black border, which at the anal angle dwindles away to nothing, UNDERSIDE, forewing with the ground-colour black, but with a large area from the inner margin extending on to the disc powdered with whitish ; the discoidal and submarginal spots as above, but pure white, larger, and much more prominent. Hindwing with the immediate base of the wing black; then a broad curved rich crimson area, commencing on the costal nervure and ending on the abdominal margin, crossed by the black veins, slightly sprinkled with black scales ; followed by a rather narrow highly irregular black band ; the outer half of the wing pale chrome-yellow, gradually darkening to a deeper chrome in the two posterior interspaces, the veins crossing this area black, from the first median to the second subcostal nervule gradually outwardly dilated and forming between those veins a broad black border. FEMALE differs from the male only in the wings being somewhat broader, forewing with the apex more rounded. Apparently nearest to D. ninus, Wallace*, from Mount Ophir, Malacca, Malay Peninsula, but unknown to me except by the original description and figure, from which it differs in its larger size, both wings much broader, the forewing on both sides less heavily marked, two discoidal and seven submar- ginal spots only, no basal bluish patches whatever, the hindwing with no crimson basal patch on the upperside ; on the underside the crimson patch and the black band following it are twice as broad, thus reducing the chrome-yellow area in the discoidal cell by half. It is even more closely allied to D. crithoé, Boisduval, from Java, as identified by me, but may at once be known by the crimson band on the hindwing below being twice as broad, and with its outer edge evenly curved, instead. of straight, and no discal white patch on the upperside of the forewing.

UNDERSIDE, forewing with the inner margin broadly white, eradually merging in the submedian interspace into the yellow colour of the disc and base ; the black apical and outer marginal areas much as on the upperside, bub extending narrowly into the outer end of the cell ; bearing six submarginal spots, of which the two anterior ones are clear yellow, the rest white ; there is also a second white spot in the lower discoidal interspace mid- way between the submarginal spot and the lower disco-cellular nervule ; the base and disc of the wing reaching anteriorly to the costal nervure clear yellow. Hindwing dull bronzy-black throughout except a small streak of clear yellow anterior to the costal nervure ; a submarginal series of six small clear yellow spots placed between the veins, the one in the submedian interspace geminated, This species is perhaps one of the most remarkable in the genus. On the upperside it has somewhat the appearance of Huphina nama, Moore, which I have also from the mountains of Sumatra, and for which it would certainly pass without notice when flying. D. datames is very closely allied to D. momea, Boisduval, from Java, the male differing from the same sex of that species in the costa of the forewing being black up to the subcostal nervure instead of white, the black apical area of greater extent and reaching the inner angle, which it does not do in D. momea ; in the hindwing the black powdery outer border is unmarked, in D. momea it bears three white spots placed one in each interspace between the second median and second subcostal nervules ; on the underside of the forewing the yellow coloration is of a deeper shade, and is more extensive, in D, momea the white coloration of the inner margin extends outwardly as far as the second median interspace, thus greatly reducing the yellow area ; the two anterior spots of the submarginal series are yellow, in D. momea they are white ; in the latter species there are three discal white spots, in D, datames only one ; and in the hindwing there is no discal series of 54 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol. VIII, streaks between the veins as there is in D. momea. I possess a single pair only of D. momea. Described from a single male example in Dr. Martin’s collection, Subfamily PAPILIONINA. 14. PAPILIO (Dalchina) SARPEDON, Linnaeus, Pl L, Fig. 11, ¢.

It is a very remarkable fact that in certain groups of Papilios the females are far more often met with than the males, This is especially noticeable in the small group which contains P. sycorax, P. priapus, Boisduval, and P. hageni, Rogenhofer, all of which are remarkable in having the face and anterior portion of the thorax above pale buff-yellow. Even the Battaks have noticed this curious feature, and call the butterfly “ white-head.” P. sycoraz, as Mr. Grose Smith points out, is obviously close to P. priapus, from Java, but having only three female specimens of the latter, | am unable to make a comparison between the respective males of the two species. The females differ chiefly in the outer area of the hindwing on both sides of P. sycorax being greenish, in P. priapus buff-yellow. Dr. Martin has only obtained three males of this fine species, two of which he has generously presented to me, together with four females, Mr. J. Wray, Jr., has also sent me a female from the Perak Hills. 16. PAPILIO (Pangerana) HAGENI, Rogenhofer, Pl. M, Fig. 2, 9. Papilio hageni, Rogenhofer, Verh. zool.-bot. Gesellsch.

A littoral plant, cosmopolitan on tropical sea-shores, The sea-shore form differs so markedly in appearance from the usual inland forms and agrees so well with the description of var. diffusa Hook. f., that it might be convenient to restrict the varietal name “‘ diffusa” to it alone. It does not, however, deserve specific rank, for, as is pointed out in the Hora of British India, it is impossible by their morphological characters to draw a line between the various forms. Byen if recognised as a species, it could not be dealt with as 5. diffusa Linn. since the probability is that Linneus based his descriptions, at least in part, on the examination of inland specimens. The ‘weed’ has probably been introduced unintentionally by man. The “ shore” form very probably owes its introduction to the agency of sea-birds, though it may have been introduced by ocean-currents. 8 58 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol. VIII. 124. WPisonia alba Spanoghe i Linnea, xv, 342; Hook. f., Flor. Brit. Ind., iv, 711. Bitrapar ; Fleming ! A littoral species confined, if Spanoghe’s species be really distinct from all the Polynesian and Malayan ones, to the Andamans and Nicobars. ‘The species is rare in the Andamans beach forests (Kurz), but it is plentiful on the shores of Narcondam and on those of Batti Malv—one of the Nicobar group. The tree is only known in India and Ceylon as acultivated species; but as it does not occur on any of the other islands of the group, and as Bitrapar is an uninhabited island, the presence of the species in the sea-coast jungle here must be: independent of human interference. Its fruits may have been introduced by birds, since the glutinous lines along their angles admirably adapt them for this mode of dispersal ; but as the majority of the birds that visit Bitra must be sea-fowl, it is much more likely that the species has been introduced by means of ocean-currents. ‘Though not wild, it is frequently cultivated in Ceylon (¢.9., ab Colombo) near the sea—indeed away from the sea it refuses to grow—and, if the tree does not exist in Malaya, Ceylon, cultivated trees may be supposed to have yielded the fruits that have reached the Laccadives. One point, however, against. the species being confined, as an indigenous tree, to the Andamans is that the species has been long cultivated in India and Ceylon, and. it is therefore extremely unlikely that the plants originally introduced into India. came from that group: of islands, with which, save for a short period in the end of the last century, there was, till thirty years ago, practically no communication. It appears, indeed, as Sir Joseph Hooker suggests, to be little more than a form of the Polynesian Pisonia inermis Forst. AMARANTACE. 125. Amerantus viridis Linn., Sp. Pl.

A littoral species extending from the Mascarene Islands and Eastern Africa to Ceylon, the Andamans, Malaya, Australia and Polynesia; like Ochrosia borbonica this does not occur on the coast of India, though it is found as far north as Great Coco on the west and as Mergui on the east of the Andaman Sea. Meissner (DC. Prodr., xv, pt. 1, 262—264) omits to quote, and the Hora of British India (v, 188) does not cite Roxburgh’s account of Hernandia ovigera (Flor. Ind., iii, 577-578), which his own diagnosis clearly shows to be a species different from Hernandia ovigera Linn. (Aman, Ac., iv, 125), founded on Rumf’s figure (Herb, Amboin., iii, 198, t. 123) of Arbor ovigera. Roxburgh notes the discrepancies, and explains them by depreciating Rumf’s drawing. In reality, however, Roxburgh’s description is a most vivid and accurate one, made from living specimens, of the species named by Meissner (DC. Prodr., xv, pt. i, 263) Hernandia peltata. Roxburgh cites Gaertner’s figure (Pract. 1, 193, t. 40, f. 8) asa “ very accurate” delineation of the fruit of this tree—an exceed- ingly just remark, which, however, Meissner has overlooked, for he quotes Gaertner’s description and figure as referring to Linnaeus’ species, though they differ very materially from both Rumf’s figure and Meissner’s own description of the fruit of Hernandia ovigera, Hernandia peltata, the species now under review, is a purely old-world plant which has been treated by Linnaeus and, with the exceptions of Gaertner and Roxburgh, by all botanists subsequent to Linnaeus till the appearance of Meissner’s treatise (1864) as conspecific with the American Hernandia sonora ; even now Sir J. D. Hooker (Flor. Brit. Ind., v, 189) suspects that 4. peltata is no more than a variety of H. sonora. And the basis of the differentiation by both Gaertner and Roxburgh of the present plant from H. sonora does not lie in the differences between the two plants that Meissner has pointed out, but in the fact that Linnaeus included under H. sonora not merely the American tree to which Meissner would restrict that name, as well as the Ceylon tree which is undoubtedly H. peltata, but also—though doubifully and with the remark “ sed fructus alienus” (Amen. Ac., iv, 117)—the tree figured by Rumf (Herb. Amboin., ii, 257, t. $5) under the name Arbor regis. Believing, apparently, that Rumf’s Arbor regis was, a8 Linnaeus thought, a Hernandia—a belief perhaps partly just— but realising that it could scarcely be the tree he had before him, and seeing that it agreed so thoroughly with the figure and description of H. ovigera given by Gaertner, Roxburgh, not having in his possession specimens of the true #. ovigera, followed Gaertner in bestowing that name on this species. This course was hardly just to Rumf if Gaertner and Roxburgh believed Rumf’s figure to be correct, hardly just to themselves if they had any grounds for supposing it to be erro- neous, It now appears that Rumif’s figure is wonderfully reliable, for, besides his * BOTANY OF THE LACCADIVES. 61 figure from a tree in Amboina, there are before the writer Specimens of un- doubtedly this species from Java (Zollinger n, 2861, which, however, Zollinger hinself has identified with H. sonora) and specimens recently collected by the officers of the “ Eyeria” in Christmas Island, where H. ovigera occurs (Hemsl., Journ. Linn, Soc., xxv, 357) on the summit, elevation about 1,290 feet, a rather remarkable fact, since, according to Rumf, it occurs, like the other Hernandias, “ semper in arenoso solo circa litora.”* As has been remarked, the belief of Linnaeus, and of Roxburgh that Rumf’s Arbor regis is a Hernandia is probably partly justified, for it is possible, from his account of the habitat of his tree—“ occurrit tam in litore inter leves ac humiles “stlvas ”’ (quite the situation affected by Hernandia peltata) “ quam in montibus “a altioribus silvis”’ (where to find H. peltata would be somewhat surprising) — that Rumf has included two trees in his description. His figure, moreover, bears out this, for some of the leaves are without, while others exhibit, a pair of glands where the petiole joins the leaf. The figure as a whole, however, suggests at once, as Lamarck (Hneye, Meth., iii, 128) a century ago pointed out, a Euphorbiaceous plant, while Rumf’s description of the fruit is altogether suitable to that of a Species of this order. The first authors to recognise Rumf’s Arbor regis, however, were Teysmann and Binnendyk, who described it as Capellenia moluccana (Nat. Tyds, Ned, Ind., xxix, 239), founding a new genus to accommodate it ; as, however, Capellenia does not differ generically from Endospermum, the tree has been re-described by Beccari as Endospermum moluccanum (Malesia, ii, 38) in his treatise Peante Ospitatrici, where another species from New Guinea (Endospermum Sormicarum Bece., Malesia, ii, 44, t. 2) is described, which shares with Rumf’s tree the character of sheltering a species of ant in its hollowed stems and branches, Teysmann and Binnendyk described their species from trees grown in the Botanic Garden at Buitenzorg; Beccari does not mention the habitat of the N ew Guinea species; in the Calcutta Herbarium there are, however, examples of another closely related species, with the same hollow branches, collected. in Sumatra by H. O. Forbes, which were obtained on the volcano of Kaba at 3,500 feet elevation, This fact, therefore, does not oppose, if it does not corroborate, the surmise that Rumf under Arbor regis has included. two trees, one found only on, SER es ee I LY NCE) ere 1 ened * Two parallel instances known to the writer of littoral species ascending to a con- siderable height are met with in N arcondam, where Morinda bracteata ascends to 2,300 feet and in Barren Island, where Zerminalia Catappa ascends 1,100 feet, The expla- nation of all three cases is doubtless the same ; these “ littoral” species being amongst the first to appear on the respective islands were able to spread unchecked from the shore to the summit of their peaks, and the invasion of inland species has not subsequently been sufficiently great to compel them to retire completely from the unusual localities they had at first invaded, 62 JOURNAL, BOMBAY NATURAL HISTORY SOCTETY, Vol. VIII. the coast.

Wood’s list gives the coco-nut as present on all the islands except Kalpéni Féti and Akati Féti, which are mentioned as mere sand-banks, but the send-banks of Pirmalla and Pittiand the coral islets on Cherbaniani and—if, indeed, there are islets there—on Cheriapani reefs are quite devoid of vegetation, and if visited at all by the islanders are visited for the purposes of fishing or ege- collecting, not for coco-nuts and coir. Bitra, however, which is uninhabited ,has coco-nuts and is visited on account of these by people from the northern islands, The coco-nuts there, from their position as described by Robinson and Hume and from the accounts of the people, are evidently only planted. Bangéro and (apparently) Tangdro, two uninhabited islands on the Akati reef, have coco-nuts clearly, from Hume’s account of the former, sea-introduced and not planted. Whether there are coco-nuts on Suheli is not clear; according to Wood’s list, 68 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol. VIII. they occur, but the people misinformed him concerning so many of the other islands, that till there is direct evidence, the point must remain doubtful. The question whether the appearance of the coco-nut in this archipelago preceded that of man, or if the first settlers there did not rather take the coco-nut with them, is one that it is somewhat difficult to answer. 'The species is pretty certainly indigenous in the Malay countries and, perhaps, Polynesia, and seems to have spread thence to India, the Mascarene Islands and Africa. It occurs also in America, but the question—which has been seriously discussed—as to whether it found its way to the New World from the Old or vice versa, has not yet been satisfactorily answered. The introduction of the coco- nut into Ceylon at all events has been in all probability a deliberate act, and, as M. de Candolle reminds us (Origin of Cultivated Plants, p. 435), at a period so recent as to be almost historical. That the geographical extension of the tree is largely due to human agency does not admit of question, but that it has been in every place where it occurs intentionally introduced, it is neither possible nor necessary to believe. Its fruits are highly capable of ocean-distribution and form a constant feature of ocean-drifts on tropical shores, and it is one of the earliest Species to appear on newly emerged coral or volcanic tropical islands, Ag regards the Laccadives, if man did not first settle there on account of coco-nut trees being already present, it is difficult to conceive what he went there for ; the surface is not adequate, nor are the conditions favourable for extensive cereal or pulse cultivation, and as for a certain period of the year the people have to take their boats away from the islands to places of safety on the Malabar Coast, it is clear that fishing could never have been a general or con- stant industry among them. On the other hand, the coco-nut is in the strictest sense a cultivated species on all the inhabited islands, and is a planted species even in Bitra which, on account of its want of a water-supply, is only a visited island ; and though in Bangdro it is not cultivated or planted, this island may have only been stocked by nuts from Akati, the main island on the same atoll, subsequently to a deliberate introduction of the species into Akati itself. Still the state of affairs in Bangdro proves that the tree here can be, at least locally, sea-dispersed ; and taking into account the uninvitine ap- pearance that the islands must offer, were they destitute of coco-nuts, one cannot but think it probable that the species reached the archipelago independently of human agency and prior to human settlement, while the necessity for constant renewal and, as the population increased, for planting to the greatest advantage, has insured that now in all the inhabited islands none but cultivated trees are to be found. In most of the islands it is deemed necessary to raise the seedling coco-nuts with care and attention till they are a year old, when they are transplanted and BOTANY OF THE LACCADIVES. 69 watered for a few weeks till they become firmly established. After this the young trees are left entirely to themselves, and are neither watered nor manured ; they come into bearing in Kiltan in from 8 to 10 years, and produce fruit so vigorously and. plentifully that it is sometimes necessary to support the luxuriant growth of nuts artificially *; in this island, moreover, the preliminary attention to seedlings is not required. In some of the other islands, as in Chitlac, where the soil is much poorer, the trees do not come into bearing till they are 15 to 20 years old, each tree at best producing only about 50 nuts per annum as against 80 to 85 nuts a year in Kiltin, In Kadamum, too, backward though the cultivation in that island is, the average per annum is about 80 nuts per tree; in Améni, where the cultivation is almost as extensive asin Kiltsin, the average is only about 60 nuts a year from each tree. These figures are given. by Robinson, after care- ful and prolonged enquiry, as representing the yield in 1844 and 1845; Hume gives the average all over for the four British islands in 1875 at 80 nuts per tree per annum}t—doubtless rather a high general estimate, though probably representing the yield of what the people in any of the islands would themselves consider a good tree. Robinson thinks that 60 to 70 nuts would be a pretty fair general average for the whole of these islands, and this is likely to be nearer the truth than the higher estimate. 'The islanders try to plant only /irst class trees, and they aim at obtaining such as will come into full bearing in about 10 years, throwing out every month after that age is reached a fruiting-spike bearing 15 to 20 nuts, and so yielding 180 to 250 nuts a year, and going on bearing at this rate till they are 60 years old. They often do go on bearing, it is said, till they are 70 or 80 years of age, and some are believed by the people to be more than a century old, But a tree that produces a fruiting-spike every month is quite a rarity ; 9 to 10 fruiting branches are all that can be hoped for in twelve months, and from accidents and casualties among the nuts, 8 to 10 a Spike is a very high average of nuts. Indeed, it is only trees with an eastern exposure and trees growing in the Aa in the centre of the islands that yield so highly ; those with a south-westerly exposure or those on the drier parts of the best islands yield as poorly as those of Chitlac, where the conditions, as a whole, are unfavourable, There is very little exportation of coco-nuts from the islands, much the greater portion of the crop being required for home consumption. As, more- over, the great product of the islands is coir, not coco-nuts, an immense propor- tion. of the crop is gathered before the nuts are perfectly ripe and before the kernel is in the best condition for yielding oil. If allowed to remain on the * Robinson, Madras Journal, n. s, xiv, 24, t ‘Stray Feathers,” iv, 410. 70 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol. VIII. tree for twelve or thirteen months, which is the time required for perfect ripening, the husk becomes hard and woody and the coir difficult to separate from the woody particles, requiring longer soaking in its preparation, which darkens its colour and spoils it for the market ; being harder and coarser, too, it becomes, though not weaker than the best coir ought to be, much more diffi- cult to twist. If, on the other hand, the nuts are gathered too soon, the coir obtained, though excellent in colour and easy to manipulate, is too weak for yarn, though quite good for minor purposes, such asa stuffing material for ma xttresses. The proper age of nuts for coir-making is ten months; at the end of the tenth month they are cut and husked, the husks being thrown into soaking-pits, where they are left for a year. These soaking-pits are simply holes in the sand on the lagoon-shore of the various islands, in which the husks are buried and covered over by heaps of coral-blocks to protect them from the ripple of the waves. After twelve months’ soaking the husks are taken from the pits and the coir is separated from the refuse of the husk by beating. If taken out earlier, it is very difficult to rid the coir of impurities and woody particles; if left longer, the fibre is found to be weakened. In Améni, where, as has been said, the island occupies the whole lagoon-space, and there is, therefore, no protected seashore suitable for coir-soaking, the husks have to be buried in pits dug through the coral-crust within the body of the island. ‘The coir is here, there- fore, soaked in fresh, instead of salt water, one result of which is that the Améni coir is weaker than that produced in the other islands; this is, no doubt, the result of the action of some of the products of decomposition in the water of these tanks, A further effect of this method of soaking is a discolouration of the fibre, for the water in the tanks never being changed becomes foul and dark- coloured by the decaying vegetable matter, and imparts this tinge to the coir. The two effects taken together, or perhaps rather the second, used by the buyer as an index of the first, renders Améni coir a less marketable product than the coir of the other islands and reduces it to the level of most of the coir manufactured on the Malabar Coast itself, which is practically all made in this way, protected seashores on which to bury the husks being exceedingly rare except within the lagoons of coral islands. In separating the coir after the beating by sticks to break up the adhesion and remove impurities, the coir is hand-rubbed, chiefly by the women, to remove the woody tissue between the fibres. It is then rolled into loose pads as thick as one’s finger by the palms of the hands before being twisted into yarn, of which two strands are made at once.* * J. Shortt, F.L.8, ; Monograph of the Coco-nut-palm, p. 16, Madras, 1888. BOTANY OF THE LACCADIVES. 71 The yield of fibre is estimated by Robinson at one pound of coir from each 10 nuts, giving 35 fathoms of yam. He adds* that “2 Ibs. of such yarn, “measuring from 70 to 75 fathoms, are made up into soodies, of which there are “fourteen to a bundle, averaging about a maund of 28 Ibs. A Mangalore candy “of 560 lbs, will, therefore, be the produce of 5,600 nuts, and should contain “ about 20,000 fathoms of yarn.” In contrast with this yield, Robinson mentions that it takes only three of the large coarse coast nuts to yield a pound of coir, but that this coir will only produce 22 fathoms. A ton of Laccadive coir will thus produce 80,000 fathoms of yarn as against 50,000 yielded by a ton of Malabar coir, By Mr. Robinson’s figures, it will take over 20,000 nuts (22,400) to yield a ton of coir, which should produce 784,000 fathoms of yarn. Mr. Hume (Stray Feathers, iv, 440) says it takes about 80,000 nuts to yield a ton of coir, Tt is clear from what hag been written regarding the Laccadives that they yield by far the best coir produced in India, and it will be equally evident from what has been said here that their superiority lies altogether in the facilities for Sea-soaking offered by their lagoons, Yet from all the information that a consultation of the ordinary trade returns will yield, an enquirer into them might, as Watt remarks,t conclude that the Laccadives export no coir, In trade returns the Laccadive coir from British Islands is given along with that from the Malabar Coast, and in European markets the best Malabar or Indian coir is spoken of as Cochin coir. As a matter of fact, little coir comes from Cochin, and it does not present any features peculiar to itself or Superior to those of coir from other parts of Malabar. What the European merchant means by Cochin coir is pretty certainly Laccadive coir. Even when the coir is known to be from the Laccadives,some misunderstanding is produced by its being spoken of as Kiltan coir or Améni coir. As a matter of fact, Kiltén coir has not quite the local reputation of either Chitlac or Kadamum coir, whereas Améni coir is distinctly inferior to that produced in any of the other British islands, The application of the term Améni coir to the best qualities arises from two circumstances—the fact that the island of Améni is one of the largest and often gives its name Amendivi to the whole group, and that, till quite recently, the lower caste people of Kadamum, where excellent coir is produced, were in some degree subject to their higher caste neighbours of Améni, and were compelled to ship their produce to the mainland in Améni boats, Besides coir manufacture, a certain amount of coarse sugar (jaggery) manu- facture is carried on, not at all extensively, however, in the British islands, since * Robinson, Madras Journal, n. s., xiv, 16. Tt Dict. Econom, Products of India, ii, 421. 72 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, Vol. VILL. the higher prices given for their coir render its manufacture more profitable to the people. In the Cannanore Islands, where coir is under monopoly and the Cannanore Raj gives much poorer prices for that article than the inhabitants of the British islands obtain, large quantities of jaggery are produced both for home consumption and for export to the people on the British islands, the chief islands in which it is manufactured being, according to Robinson, those of Anderut and Korati, PANDANEZ. 162.

A littoral species extending from the Indian Coasts to Malaya, Australia and Polynesia. Tn the Laccadive Islands proper there is not, in densely peopled and carefully planted islands like Kiltan, more than the merest remnant of a Pandanus sea-fence left, though in uninhabited islands like Bangaro and in partially occupied ones like Kadamum, it is well represented. But, curiously enough, it is quite absent from the uninhabited island of Bitra, where also Cocos nucifera does not occur as a littoral and sea-introduced species. In Minikoi, however, where the island is fully occupied and carefully planted, the Pandanus sea-fence has been allowed to remain as a belt all round the island. ‘This belt of jungle harbours an immense number of rats (Mus rattus VAR. rufescens)*, which here, as in the other islands, prove very destructive to the coco-nut crop. Captain Wentworth Hamilton, Port Officer of Gopalpur, who commanded the 8. 8. ‘“ Martha Heathcote” during a recent official visit to Minikoi, informed thewriterin 1889 that the disturbances which led to the visit arose out of a Government order to cut down this jungle and, by removing their shelter, to render possible a systematic attempt to exterminate the rats. The populace objected most strongly to the order, on the ground that this belt of jungle is the abode of evil spirits that would be certain, were their domain invaded, to retaliate by bringing misfortune on the island. Minikoi, as has been already said, though Laccadive as to political connection, and as much Laccadive as Maldive as to situation, has a Maldive population ; there is no evidence of superstition So gross among the Mappila population of the other Laccadives; at all events, they do not appear to have any scruples about clearing away the Pan- danus belt. * Hume, “ Stray Feathers,” iv, 433.
