Introduction. 

Since the publication of the Enumeratio Plantarum For- 
mosanarum'-* and Flora Montana Formosse/^ a large number of 
collections has been sent to me for determination, by the Go- 
vernment of Formosa. The collections are in greater part from 
the mountainous regions of the island and contain a considerable 
number of novelties. As the flora of Formosa has a close 
affinity to the floras of Japan and China, it is very important, 
in order to work up the materials, to make an exhaustive com- 
parison of the collections with specimens from the two countries.

At the same time, as the flora of the island contains a con- 
siderable number of elements from India, including the Himalayas 
and the Malay peninsula and archipelago, it is equally desirable 
for my work that the same should be done with the specimens 
of the regions above mentioned. For a comparison with Japanese 
specimens, the Herbarium at Tokyo will answer fairly well, as 
it includes nearly all Japanese plants, though not exhaustively. 
Chinese plants, however, are here only very poorly represented. 
I, therefore, found it very unsatisfactory to work up so big a 
collection only in the Herbarium at Tokyo. Moreover, as a con- 
siderable number of Chinese plants are represented in the Her- 
barium at Kew, and also in that at Dahlem, and the type speci- 
mens of Feanchet are especially preserved in the Herbarium at 
Paris, and those of Maximowicz, in that at St. Petersburg. 
I thought it very necessary for my work to see all the plants 
represented in the principal herbaria of the West. It was my 
great good fortune that I was given an opportunity of visiting 
these different herbaria in order to make an exhaustive com- 
parison of my materials with the collections preserved in' them. 
With this intention I first went to Kew taking all my materials 
with me. There I pursued my work with specimens of the 
floras to Avhich our flora is more or less related. The comparison 
made, in most cases, was confined to the flora of Asiatic regions, 
especially, to China, Korea, India, the Himalayas, and the Malay 
peninsula and archipelago ; but, sometimes, it was extended, when 
necessary, to Australia, the Arctic and Antarctic regions, Europe, 
Africa, America and even to Polynesia. I found that many of 
the species of my collections are represented in the Chinese 
herbarium at Kew, and also among the specimens from other 
regions. At the same ti^ne, I found also that the greater part 



MATERIALS FOE A FLORA OF FORMOSA. Ö 

of my materials is not yet represented at Kew, and that, in great 
probability, tliey are species not yet described. After finishing 
my work at Kew,^^ I went to the Herbarium at Paris, in order to 
see the type specimens of Chinese plants mainly described by 
Feanchet. Then, my work was pursued in the Herbarium at 
Dahlem wliere are preserved a good many collections of Asiatic 
flora. My purpose in going to Dahlem was to see especially the 
specimens mentioned in Prof. Diels' " Die Flora voir Central 
China." ^^ In Dahlem, as in Paris, I devoted myself to making 
notes of the specimens preserved there, as I had not brought my 
materials with me. I especially devoted myself to making 
sketches, on tracing paper, of the specimens which are represented 
only in Dahlem and nowhere else, so that I could make a close 
comparison with these sketches on my return to Tokyo. After 
finishing my work, I went, with the same purpose, to the Her- 
barium at St. Petersburg, in order to see the type specimens of 
Maximowicz. During my work on the continent, I was saccessful 
in placing some species which I had not been able to determine 
at Kew. Still, many of the plants in my collections which remain 
as yet nndetermined, are not represented in any of the herbaria 
on the continent. It is, tlierefore, highly probable that they are 
species not yet described. 

The plants mentioned in the present work are mostly of 
species newly descril)ed and, if not, tliey are new to the flora of 
Formosa, tliougii tliere are a very few which were previously

2) D)irinp my stay at Kew, I was away from my -worlc, for a little more than a week, when 
I went to Brussels to take part in the International Botanieal Congress, then being held there, 
at which I presented a paper entitled " Botanical Survey of the Government of Formosa, with 
short Sketches on the Vegetation and Flora of the Island." The paper is now in pre.^s at 
Brussels.

recorded from that island. The references here made under each 
species are extremely limited, as there is no space for full ac- 
counts. Critical views regarding species already described by my- 
self or by others, are here given. In the present work, it is my 
desire to mention all the species recorded from Formosa, which 
have appeared in difierent publications, since the issue of the 
Enumeratio Plantarum Formosanarum and Flora Montana For- 
mosae. So that, practically speaking, the present work is an 
exhaustive supplement bringing our former publications up to 
date. 

To mention the number of species of the flora* of the island, 
known to us up to the present time, tliere are, in the Enumeratio, 
1999 species belonging to 701 genera and 153 families. In my 
FJora Montana, 392 species are mentioned belonging to 266 
genera and 70 families ; in the present work, I have mentioned 
735 species belonging to 343 genera and 109 families, thus 
adding to our present knowledge of Formosan flora, 567 species, 
72 genera and 2 families. Excluding all those species which 
appear for a second or third time, in the above three papers, 
the total number of the plants of the island is 2660 species 
belonging to 836 genera and 156 families. The following list 
shows genera added to those mentioned in our former publications. 
Most of them are new to the flora of the island.

In the present work, a few species are mentioned under 
families different from those to wliich they are referred in the 
former publications. As the alteration of families is a matter 
of importance, I shall here try to comment briefly on this point. 
There are three species wliich are properly transferred from one 
family to anotlier. Ojic is a plant which was called Echmannia 
Oldham i Hemsl, formerly leferrcd to Scrophnlarinea\ but now 
to Gcsnerace.T. The reference to the species is ,ii;iven under 
the heading of the genus. The plant was ürst referrcil to Fch- 
mcmnia^^ by AV. B. Hemsley who afterwards thought it better to 
regard it as i epi'esenting a distinct genus from Rchmannia. He 
then established a new genus, Malsumicria,'' for the plant, and 
referred it to Gesncraceœ oti account of its perfectly one-called

ovaiy with two parietal placentœ. Almost at the same time, 
this plant attracted the attention of Soleeeder who saw the very 
same specimen at Kew, and established a new genus called 
Titanotrichiim^'' which was published in September, 1909, when 
the description of Hemsley was in press. The priority has at 
last been given to the genas of Soleeedee. In tlie present work, 
the plant is mentioned as Tiianotrichum Oldhami Soleeed. and is 
referred to Gesneracea3. Another plant is Logania dentata^^ 
formerly described by myself, which should be transferred from 
Loganiacese to Scrophularinese. In 1906, when I published 
the plant in my Flora Montana Formosae, I was informed by Mr. 
E. D. Meeeill that he thought that the Philippine plant Nertera 
dentata Elmee^' (with which my plant is identical) should be refer- 
red to Hemiphracjma heterophylla Wall, of the Himalayas. I also 
alluded to this matter in the foot notes to my paper in which I 
expressed the opinion that it was still questionable whether my 
plant should be referred to Hemiphragma or not. At Kew, I 
compared it with the type of the latter species and found that 
they were A^ery similar excepting slight differences in the number 
of the corolla-lobes and in the attachment of the stamens to the 
corolla-tube. So far as I can ascertain from the description of 
Hemiphragma given in Bentham and Hookee, f. " Genera Plan- 
tarum II. p. 959," the genus has a five-lobed corolla and four stamens, 
afiSxed to the base of the tube. But, in my plant, the corolla 
is four-lobed and the stamens are also four, but, affixed to the 
middle of the tube. It may be questioned, however, if the 
flowers of my plant may not be imperfect ones, as it was

collected when the flowering season was nearly over. I exammed 
a considerable number of the specimens, but I could not find 
more than one or two flowers upon which the description and 
figures in my papar could be based. It may be well conjectured 
that my plant in tlie normal state of its flowers may have a five- 
lobed corolla witli four stamens. I therefore think it better to 
transfer my plant from Logan iacea3 to Scrophularinea?, 
referring it to Hemiphragma lieterophjlla Wall. Another plant 
which I may here mention, is ElUsiophi/Uum pimiatum Making, 
which was referred to Hydrophyllaceœ, but, in the present 
work, is transferred to Scrophularineœ. In 1871, Maximowicz 
established the same genus upon a Japanese plant in '' Mel. Biol. 
Vol. XIII. p. 18", then named by him as E. reptans. It is very 
probably to be referred to Polemoniacese, because of its seeds 
which produce a considerable amount of mucilage in the moist 
condition, — a character which is all but peculiar to the same family. 
The plant has also a close relation with Hydrophyllacese, so 
far as the leaves and flowers are concerned. It seemed, therefore, 
rather questionable to Maximowicz himself, to what family the 
present genus should be referred. In 1876, the same genus was 
referred to Hydrophyllaceoo by Bentham and Hookee. f. in their 
"Genera Plantarum '* II. p. 829. A little later, in 1890, it was 
referred to Scrophularineœ by Bâillon in " Bull. Soc. Linn. 
Paris, No. 103." Hero, he expressed his opinion that tlie doubtful 
genus belongs neither to l^olemoniacea3 nor to Ilydrophyllaceœ, 
but to Scropliularinea). Moreover, he stated that its nearest 
01 kill is Litoi'cllii of the same family. In 1892, it was again re- 
ferred to Ilydrop li y llaceae by Petee in " Engl. u. Peantl. Nat. Pfl.- 
i'am. IV. o-a, p. Go." As to the nomenclature of tlie plant, there had 
been no difliculty, until Mr. T. Makino (1900) called his attention 



ö AET. I. — B. HAYAÏA : 

to the similarity of the figures of Moseleya pinnata Hemsl. 
in Hookee'sIc. PL XXVI. t. 2592, (1892), and his drawings of 
Ellisioplujllum reptans Maxim, which he had just made. The same 
plant is an extremely troublesome one, as to its genus and 
species as well as its family. Previous to the establishment of 
Ellisiophyllum by Maximowicz, the same plant was found in Nepal 
and is described as Mams pinnatus Wall. The plant was after- 
wards referred to Our isla (1835), then to Hornemannia (1846), 
then to Sibthorpia (1876) and finally to Moseleya (1893). The 
last genus was established by W. B. Hemsley, as there was, as 
he thought, being quite una.ware of Ellisiopliyllum of Maximowicz, 
no proper genus for the plant. As is clearly seen in the com- 
parison of the drawings of Moseleya and Ellisiophyllum, 
above mentioned, they are two different genera established 
for one and the same plant. Accordingly, it is clear that the 
former should be reduced to a synonym of the latter. The 
present plant should, therefore, be referred to Ellisiophyllum 
with the specific name of pinnatum, as is stated by Mr. T. 
Makixo.^^ Now I may return to the question as to what family 
the plant should properly be referred ? In my paper " Flora 
Montana Formosœ," I mentioned the plant under Hydrophylla- 
ceœ. In 1909, Herr Professor A. Brand wrote me that he had 
some doubt about this plant's belonging to Hydrophyllacea3 
and expressed his desire to study it, asking me to send him the 
materials. This being done, he soon published his paper on 
Ellisiophyllum'' in which he expressed the opinion that Baillon's 
statement, to which I have referred above, was correct. Accord- 
ing to his opinion, all the Hydrophyllaceous plants have, without

exception, two parietal placentae, which connate themselves in the 
innerside of the capsnles. But, it is quite otherwise with the 
present plant, which bears only a placenta rising b}^ itself to mid- 
way from the base of the ovary, i.e. a central placenta, as is the 
case with Scrophulariaceous plant. The genus is, therefore, not to 
be referred to Hydrophyllacese, but should be referred to 
Scrophularine93. There is a little difference between his state- 
ment and Mr. Making's drawings, regarding the placenta. So far 
as I can judge from the latter figures, the ovary is perfectly two- 
celled, with axial placentae. Bnt, in the figures given in Hookee's 
Icônes Plantarum, the ovary is nearly, but not perfectly, two- 
celled, as the placentae are free at the apex. Although these 
differences exist, they are, in my opinion, to be regarded as 
results of individual mutability, to which all plants are more or 
less subject. Taking all these things into consideration I think 
the plant should be referred to »Scrophularineae, as was stated 
formerly by Bâillon and quite recently by Prof. Beand. Finally, 
1 may mention one more plant which is also extremely difficult 
as to its reference. It is Triplostegia glandulifera Wall. The 
genus was first established by Wallich on a Himalayan plant 
in liis manuscript and also in DC. Mem. VII. t. 4, referring it 
to Valériane«), as we see in "DC. Prodr. IV. p. 642." 
The genus is, however, transferred to Dipsaceae by Bentham 
and HooKEE, f. in their Genera Plantarum II. p. 158, with the 
remark "Genus liucusque ad Valerianeas quibus inflorescentia 
accedit adscriptum, sed involucellum, semen albuminosum, folia 
et indumentum omnino Dipsacearum ct odore Valerianearum 
caret," and also on p. 1230, with another remark, " Stamina per- 
fecta saepe 3 tantum ut in Valeriana aflhiibusque, et genus 
omnino medium tenorc vidctur inter Valerianeas et Dipsaceas, 



10 AET. I. B, HAYATA : 

etsi characteres essentiales posterionim." The genus is also 
referred to Dipsaceae by Hemsley in Foebes and Hemsley's 
Index Flora Sinensis, I. p. 399, and also by F. Hœck in Eng. 
n. Peant. Pfl.-fam. IY.-4 p. 187. When I examined the plant in 
the Herbarium at Tokyo, where we have very few Chinese 
specimens for comparison, I thought that it must be a plant 
belonging to Valériane se, and I saw that the plant was 
quite referable to the genus Hœckia, then newly established by 
Professors Englee and Ge^bnee in Diels', " Die Flora von Central 
China. '"^ 1 saw also that the description of //. Aschersoniana Engl. 
and Ge.^bn. accorded fairly well with my plant, though there 
are some minute points in which they do not exactly agree. 
As the plants of this family are usually subject to some muta- 
bility in the magnitude of flowers and leaves, I thought the 
present plant to be identical with H. Aschersoniana. During my 
work in the Herbarium at Dahlem, I examined the type of tlie 
Hœckia and also the specimens of the Triplostegia of the Hima- 
layas, and found that they are exactly the same as those with 
which my plant also is identical. The present plant is, therefore, 
mentioned, in this work, under the name of Triplostegia glanduli- 
fera Wall. As to the position of the present genus, it is, in my 
opinion, much more desirable to refer it to Valerianese, than to 
place it in Dipsacese. 

I may here mention another remarkable case given in this 
work. Of all the plants contained in the flora, perhaps the most 
striking genus is Oreomyrrhis, which is all but pecuhar to the 
Australian flora, belonging to Umbelliferae. The genus is, not 
only new to the flora of the island, but also new to that of the 



1) DiELs, L.— Die Flon-, von Central Cbinn, in Eng. Bot. Jahrb. XXIX p. 598. 



MATEEIALS FOE A FLOE A OF FOEMOSA. 11 

northern hemisphere. Another case of novelty is the addition of 
two famihes to the present flora. They are Hernandiacese and 
MyristicoDe. 

The materials upon which this work is based are, in greater 
part, the collections made by the Governmental Botanical Survey, 
supervised by Mr. T. Kawakami, during 1906-1909. I have also 
referred to a small set of specimens of Loo-chooan plants, collected 
by Mr. G. Nakahaea, a few dubious specimens from the Loo- 
choo and Benin islands, preserved in the Herbarium at Tokyo, 
and small collections of Formosan plants sent by Mr. S. Nagasawa 
and the late N. Konishi. 

The present work was, in great part, carried out by myself 
in the Herbarium at Kew. A few families were examined by 
the staff of the same laboratory. Of the staff, 1 may mention 
Dr. 0. Stapf for doubtful families, Mr. E. N. Beown for Ascle- 
piadeas and Aroidese, Mr. E. A. Eolfe for Umbelliferae and 
some Orchids. 

In conclusion, I must tender my hearty thanks to Prof. 
J. Matsumuea for his encouragement during the present w^ork. I 
also wish to express my sincere gratitude to Mr. K. Oshima, 
Ex-Chief of Civil Government of Formosa, by whose graciousness 
extended towards myself, I was able to visit the principal herbaria of 
tlic West. To Lieut. Col. D. Peain, Director of the Eoyal Botanic

Pétersbonrg, I am also greatly indebted for permission to w^ork 
in their herbaria. Mv verv cordial thanks are also due to Dr.

The present variety differs from the type in having much 
smaller flowers, ovate-lanceolate leaves, and not leafy inflo- 
rescence. It resembles the type in stamens and achenes, and 
especially in glabrous sepals turning black when dried. The 
type has usually larger flowers, with sepals twice as longer as 
that of the variety, and longer, looser, and less flowered in- 
florescence, with longer peduncles. The present variety is 
represented at Kew by a specimen from Hongkong, which is 
labelled C. uncinata, but is different from the type of the species 
mentioned.

30 AKT. I.— B. HAYATA : 

In my paper above cited, I mention that the present plant 
a^'recs quite well witii the description of Arabis taraxacifolia 
Andeks. given in Hook. f. Fl. Brit. Ind. I. p. 136, and also very 
like the Em^opean A. arenosa Scop. Although I did not, at that 
time, see Anderson's specimen, I thought that the plant might 
be identical with A. taraxacifolia. While studying here at Kew, 
I have compared it with the type of the some species and 
have found that they are quite different. The Formosan plant 
is distir^guishable from the Indian in having nearly erect and 
stouter pods, larger seeds, and smaller leaves and also in 
bearing very long stolons. The Indian plant appears to be of 
more tender habit, witli curved pods, narrower, smaller seeds, and 
larger, thinner leaves. Moreover, the present plant differs from 
A. arenosa Scop, in having longer pods, smaller flowers, and 
leaves with more rounded lobes. The description given above is 
drawn up from a specimen numbered 680, which is of a rather 
elongate form and prostrate habit.

There is a specimen very much like this in the Kew Herba-

typo. As the present plant is quite easily distinguishable from 
the type of C. hlrsiita Linn., it is advisable, in my opinion, to 
regard it as representing a variety of the type, rather than to 
regard it as a foi-m of it.

his Coriar. Ilic. Monoch. p. 33, I. Hanceana, has " cyniulse J

the above descriptions, we see clearly that the Loo-chooan plant is 
-* not identical with Maximowicz's species. As to the identification 
of the Loo-choo plant with the present one, 1 am not as yet in a 
position to decide it. I can only add that they are very similar.

When I mentioned the present plant in my '• Fl. Mont. 
Formos.", I was merely comparing it with a Loo-choo plant which 
had been determined by Dr. T. Itô, and referred to E. echinatus 
Wall, in the Tent. Fl. Lntch. p. 371. As the Formosan plant is 
exactly identical with Dr. Ito's plant, I nsed the same name for 
my plant. While working here at Kew, I have compared with 
Mr. Speague the present plant with the type of the named species, 
and have found that they are clearly not identical. The former 
is easily distinguishable from the latter by many points but 
especially by the very much fewer and much more slender prickles 
on the fruit. In Wallich's species, the prickles are much more 
numerous and stronger. Our plant is very near E. subsessllis 
Speague ( = £'. echinatus Loue.), but differs from it in having much 
fewer and more slender prickles. The new species is named in 
honour of Mr. T. A. Speague who has cordially assisted me in 
many ways during my work at Kew.

The present plant is near C. articulatus ; but differs from it in 
having more rounded leaves and transversely wrinkled carpels in 
a dried specimen. The leaves are nearly rounded, or slightly 
cordate at the base, shortly acute or nearly rounded at the apex, 
remotely serrulate on the margin, while those of C. articulatus are 
nearly obovate, acute or rounded, but never cordate, at the base.

The present plant is described in my paper above cited as 
representing a variety of Rhamnus arguta Maxim. At Kew, I have 
examined the co-type of the latter plant and found that the diffe- 
rence between the type and the variety is so great that I have 
thought it better to raise the latter to specific rank. The new 
species differs from the other in having slender flowers with longer 
styles, and still more in the snpra-axillary inflorescence.

The present plant was erroneously regarded by myself and 
otlirr botanists as identical with .1. oblongum Wall. At Kew, I 
liavt^ C(^mpii^ed the plant with the type of the named species and 
found tliat they do not entirely agree. I have examined several 
forms of Acer oblongum from the Himalayas, Cliina and Formosa,

but I have not found that any of the forms of the same species 
conies in accord with the Loo-chooan plant in respect of the 
shape of leaves. Accordingly I have thought it better to regard 
the latter as representing a new variety of the species. The 
present variety differs from the type in having ovate leaves, quite 
ix)unded at the base, acuminate at the apex, with three distinct 
nerves, and two distinct lateral veins on both sides of the central 
nerve. The leaves of the type are oblong, or obovately oblong, or 
rarely ovate-oblong, much more obtuse at the apex, and nearly 
acute at the base, pinninerved or obscurely three-nerved, with 
more than six lateral veins on both sides of the central nerve. 
The new variety is named in honour of Dr. T. Itö who has 
done so much for the study of the flora of these interesting 
Archipelago.

The present plant is included in P. variabilis by W. B. Hemsley 
in Ind. Fl. Sin. I. p. 263. While studying here at Kew, I 
have examined all specimens included under the same name by 
this authority, and found that the Formosan specimens are very 
distinct from any of the other forms of the species collected in 
continental China. I think, therefore, the present plant should be 
regarded as a species distinct from P. variabilis. It is near 
P. arguia, but differs in having more minutely toothed leaves.

in Fl. Mont. Formos. p. 92. Having examined the type of C, 
sinensis Hemsl. at Kew, I have, however, found that my plant dees 
not quite agree with Hemsley's species. C. formosana differs from 
C. sinensis mainly in having narrower leaves with shallower denta- 
tion, and much larger petaloid sepals. The Fermesan plant 
should, therefore, be regarded as a species distinct from the conti- 
nental plant.

The present plant is very near D. s cabra Thunb. and D. indchra 
YiDAL ; but it differs from the former in having dentate stamens 
and in the number of styles which are usually five ; and from the 
latter, in having quite obtuse leaves. In Vidal's plant, the leaves 
are usually more acuminate, and very acute at the apex. Deutzia 
crenata S. et Z. o. Taiwanevsis Maxim, cited above may possibly 
be identical with this plant, though I have found some different 
points between the description of Maximowicz and that of the 
present one ; for the Deutzia credited in Formosa by Maximowicz, 
so far as is considered from the locality given by him, may not 
l^e otherwise than this plant as it is the only one to be found in 
the lowland of Formosa. Maximowicz's plant is not near D. crenata 
S. et Z., nor is it referable to a variety of that species ; but it must 
be a quite different one, so far as the diagnosis is concerned.

As far as I can judge from the description of the variety o. 
Tai leaner s is, it is so very different from D. crenata S. et Z., that 
it is quite proper to raise it np to specific rank. The frnit of 
the present plant is very similar to those of Henry's specimen 
at Kew.

Near T. Lepiniana Cogn. ; but distinguishable by the bifid 
tendrils ; from 7\ bracteata Cogn. by the bifid tendrils and much 
lacerate bracts. Very like, or perhaps quite identical with, a 
Chinese specimen at Kew which is named IrlcJiosanthes palmata 
EoxB. The type of the same species is quite different from the 
Chinese specimen and also from the present plant. The bracts 
of the type are usually entire or but a little fimbriate in the 
upper ones, while those of my plant are very deeply fimbriate.

The present plant is mentioned in Heney's List of Plants from 
Formosa p. 46, as Alsomitra clavigera Hook. f. and is also referred 
to the same species by myself in Enum. PI. Formos. p. 164, as 
the description of Hookee's plant is, in greater part, in accord 
with my plant. ^Ir. E. D. Meeeill of the Bureau of Science, 
P. I., when we wore together looking over the Formosan collections 
in the Herbarium at Tokyo, told me that he thought the plant to be 
identical with Gijnostemma integrifoUola Cogn. To what species the 
present plant should be definitely referred was a very difficult 
question for me, mitil I saw the types of Hookee's and Cogniaux's 
species and Heney's specimen, all preserved here in the Kew 
Herbarium. A comparison of my plant witli the specimens above 



122 . AET. I. B. HAYATA : 

mentioned shows me clearly that it is exactly the same as the 
specimen in Heney's collection, (which lacks flowers), bnt qnite 
different from Hookee's plant. I have also fonnd that my 
flowering specimen accords very well with Gynostemma integrifoliola 
CoGN., the specimen of which lacks frnit. In the original de- 
scription of CoGNiAUx, there is mentioned " frnctns fuscus glaber 
vel leviter pnbernlns, 7-8 mill., crassns." The description must, 
I infer, have drawn up from a praemature fruit, as there is given 
no account about seeds. The fruit of this species are, as is seen 
in my specimen, as long as 4 cm. and has numerous winged 
seeds. The Gynostemma of Cogniaux, as far as my coUections 
with flowers and fruit are concerned, does not accord with the 
general characters of Gynostemma, but quite agrees with those 
of Alsomitra. My plant and also Cogniaux's plant, therefore, 
should be referred to the latter genus. Accordingly, the new 
combination, A. integrifoliola Hayata is much to be desired for 
the present plant. It comes very near to A. clavigera Hook, f., 
but diflers from it in having much smaller pod which is only 
half the size of those of the latter plant, and also in having 
much smaller seeds with thin wings, which are bluntly and ob- 
scurely indented on the margin. The seeds of Hookee's plant are 
much larger and have acutely, clearly and grossly indented wings.

The present Begonia is the most common one iii Formosa. 
It differs from B. laciniata Eoxb. var. Boicringiana in having quite 
glabrous leaves. The latter variety is always tomentose or 
pubescent. The Formosan one should, therefore, be another 
variety of B. laciniata to -which Mr. W. B. Hemsley also refers 
in Ind. Fl. Sin. I. p. 322. It bears some resemblance to B. 
sinensis ; but differs from it in having larger flowers and glabrous

The present plant is qnite referable to Hange's var. fonnosanum. 
The variety, however, has not any stipule, while V. erosum has a 
distinct stipule, as is mentioned by Maximowigz in the literature 
above cited. As the Formosan plant differs from the latter species 
in many other points, it is quite proper to regard it as a plant 
specifically distinct from V. erosum Thunb.

having narrower leaves, and much narrower calyx-lobes. The 
flowers of //. capitellata are nearly sessile. This appears also 
to be near H. macrostemon H. et A., which I have seen in the 
Herbarium at Hongkong, but so far as I can judge from the floral 
characters of the species given in Hook, et Arn. Bot. Beech. Voy. 
p. 192, they are not at all similar, but very distinct.

The present plant comes near V. bracteatum Thunb. from 
■which it is distinguishable by its more acuminate or even caudate 
leaves and by its larger and glabrous calyx. Also near V. Carlesii 
Dunn, and V, malaccense Wight ; but differs from the former in hav- 
ing leaves, obtusely serrulate on the margin, more or less acute at the 
base, and from the latter in having glabrous calyx.

to a Bornean species described by Dr. 0. Stapf. At that time, I 
could not compare my plant with the named species, as there was 
nothing of the Borneoan collection in the Tokyo Herbarium, nor is 
the paper of Dr. 0. Stapf accessible to me. Since coming to Kew, 
I have compared my plant with the type of the same species, and

The present plant was first identified with Plcris formosa D. Don 
by Prof. J. Matsumura. I was also of the same opinion as the 
Professor regarding the reference of the plant, as the figures given 
in Wight, Ic PI. t. 1200 quite agree with it. Since coming to 
Kew, when 1 have examined the type of P. formosa D. Dox, I have, 
however, found that the type does not agree with the Formosan 
plant. The inflorescence of the latter spreads less, the flowers 
are smaller, the leaves are obovately spathulate, less acute at the 
apex, more obtusely serrate on the margin, and very faintly reti- 
culated on the surface. There are at Kew some specimens irom conti- 
nental China, referred to P. formosa D. Don. They are also difTerent 
from my plant.

The flowers of the present plant are near B. pumilum of 
Himalaya, but the habit is quite different. Somewhat near R. 
anthopogonoides Maxim., but greatly differs from it in having much 
elongated bracts, and obovate emarginate leaves which are glabrous 
above, and glandulose below. Comes nearer II. emarginatmn 
Hemsl. et E. H. Wilson, from which this is distinguishable by the 
larger lobes of the calyx and shorter, broader, thicker, and 
more conspicuously gland-dotted leaves.

The present plant comes near Osmanthus marginatus Benth., 
but differs from it in having much thinner leaves, which are abruptly 
acuminate at the apex. As is pointed out by Prof. J. Matsumura 
in the paper above cited, the plant does not accord with Bentham's 
plant, especially in the shape of leaves. I have compared my 
plant with the type of the latter species at Kew, and found that they 
are quite different even in general appearance, though they come 
very near.

This is very near E. micrantha A. DC, but differs from it by 
the leaves which are much narrower at the base, denser cymes, 
and terete and fusiformed follicles. This is also near E. napeensis

The present Paulownia was pointed out to me by Mr. T. 
Kawakami in August, 1908, when I was botanizing on the moun- 
tain with the same gentleman. 1 found the plant in full foliage, 
but lacking flowers. The photograph given in the paper above 
cited was taken by myself on the spot. I may add that there 
exist three species spontaneous in continental China and another 
also spontaneous in the Island of Formosa. The Chinese species 
of Pauloicnia are P, Imperialis Sieb, et Zucc. (which exists also in 
Japan where it is found only in cultivation), P. Fortimei, which is 
easily distinguised from the preceding species by its much elon- 
gated leaves, and finally P. Fargesli Feanch.

Distrib. Dispersed all round the northern hemisphere. 

This is perhaps the plant recorded from Formosa as 
Suceda nudlflora in Forbes et Hemsl. Ind. Fl. Sin. IF. p. 330 ; 
for I could not find any other Suceda in the island. As 
my plant has 2-styles, it is not to be referable to Ä mcdißora, 
but finite identical with the plant figured in Wight Ic. t. 1793, 
which is rendered by Sir J. D. Hooker a synonym of S. maritima. 
It demands further investigation whether or not this is exactly the 
same as the Euroiican S. maritima.

stamens, of -which tho.se of the third order have two lower larger extrorse cells and two upper 
smaller introrse cells. It is, therefore, rather doubtful whether this should be referred to Fer-

perianth are rather thin, and the i)lant does not look like a si^ecies of the Machilus-aViea.

between the two specimens in the shape of leaves. I think, however, 
from the general appearance of the plant, that one may be the partner 
of the other, and therefore I have here described them under the 
same name. In case that they should not be of the same species, the 
present name should be used for the male plant. To prevent a confu- 
sion of nomenclature, which may have crept in from such an 
error, I have here given the descriptions of the male and female 
separately.

The present plant was referred to E\ umbellata Thunb. by 
myself in the paper above cited. Studying more carefully, I have 
found that there exists some difference between my plant and 
Thunbeeg's species, especially in the structure of flowers, though 
they are very near. It is also near E. Thunhergi, but differs from 
it in having narrower leaves, and in the corolla-lobes.

case with L. nodiflorus. It comes also very near L. odoratus ; but 
differs in having broader leaves, and in the fruit. In my species,

In C. philipp'mensis, the leaves are quite entire, more coriaceous, 
less reticulate and much larger, while in the present plant 
they are thinly coriaceous, serrate towards the apex, and acuminate 
or almost caudate. Besides, the two are easily distinguishable 
by the general appearance. Our plant is near C. australk Linn. 
and C. tetrandra, Roxb., but differs from the former by the 
quite glabrous fruit and from the latter by the leaves, which are 
serrate only towards the apex.

I have examined all the species of the genus at Kew, but have 
not been able to find any thing like the present plant. There is a 
specimen labelled C. sativa in the Herbarium at Hongkong, which 
specimen is exactly the same as the Formosan plant, but quite 
différent from the type of the named species.

The present Pinus is very near P. densißora, but differs from 
it in having more oblong ovate cone, with more elevated umbo ; 
also near P. yunnanensis and P. densata Mastees, but distinguish- 
able from the former by the smaller cones and and two leaved 
shoots, and from the latter by the more slender leaves and not 
reflexed umbos ; from P. prominens Mastees, by the much longer 
cones with less edged apophysis. I have compared my plant 
with all the specimens of the genus in the Kew-Herbarium, but 
I have not been able to identify it. I think this may be a plant 
not yet described. In this, Dr. A. Heney concurs.

The present plant is a little different from the Chinese in 
the shape of lips. In our plant, two lateral nerves of the middle 
lobe of the lip are strongly crested which unite together at the 
apex, while the central nerve is very thin and not crested. In 
the Chinese plant, the middle lobe of the lip has 3-5 nerves which 
are equally crested.

Near S. formosanus Eolfe, from which the present plant is 
distinguishable by the labellum which is trilobed, two lateral lobes 
being very small, and the terminal one very large, broad, and denti- 
culate on the margin. In S. formosanus R., the middle lobe of 
the lip is again trilobed, while in this new species the middle lobe 
is not lobed, but minutely denticulate. The present genus is se- 
parated from Saccolabium (which has no plate in the spur), by 
the longitudinal plate dividing the mouth of the spur ; also from 
Cleisostoma which has a transversal plate covering the mouth of 
the spur.

The genus to which the present species is referred, is separated 
from Sarccmthus by the transversal plate covering the mouth of 
the spur, and also from Ecliioglossmn, by the nearly round 
glandule. In the latter genus, the glandules are horse- shoe-shaped 
and the mouth of the spur is narrowed by a thickening of the 
tissue, which characters, however, do not very distinctly separate 
the genus from Cleisostoma.

The present plant is one of the most useful in Formosa. It 
is the principal source of the material of which the mats called 
" Taikö-mushiro " are made. The species exists spontaneously in 
Japan, but it does not there afford so good a material for mats, 
and therefore it is of no industrial interest. Consequently, the 
Formosan plant was regarded as quite distinct from, the Japanese 
and, therefore different from S. triqueter Linn., which is widely dis-

tribnted in the tropical and temperate regions of Eastern Asia. Some 
years ago, Mr. T. Kawakami sent me a specimen of a sedge which 
is known as the best material for the Taikömushiro, and is called 
by the name of Taikö-i (= Sedge of the Taikö-mat). Studying 
the specimen, I saw that the plant is quite the same as a Japa- 
nese sedge which is known to be identical with S. triqueter Linn., 
although there are some small differences between them in point 
of inflorescence. The differences are not, however, of such charac- 
ters which botanically separate one from the other. While work- 
ing here at Kew, I have compared the present sedge with 
numeroQS specimens of the named species preserved here, and found 
that there is a form of the species with which my plant is 
exactly identical. I have, therefore, no further hesitation in referring 
the present plant to S. triqueter Linn. It may be added, how- 
ever, that the Formosan plant is not of the same form as the 
Japanese, or as the type of the species, but is of a form peculiar 
to itself and to a few specimens at Kew.

The present specimen exactly accords with those so named

would be very remarkable fact if this Carex should really exist in 
the mountains of Formosa. It may be doubted, however, if the speci- 
men might not be one of the collections from Sachalin island, for the 
collector was sent to Formosa immediately after he had finished 
his work in Sachalin ; and it may be well conjectured that the 
present specimen, having escaped from the northern collections, 
was sent to me from the same collector then in Formosa.

The present variety differs from the type in having much 
longer bracts, acuter scales of male and female flowers and in the 
shape of the nutlets ; but in other respects they are very similar. 
Further study will prove that the variety is a mere form of the 
type.

The present [)lant is very remarkable for its dimorphous fronds. 
It is very near Pofystldiuia apUj'olluin (Sw.) C. Chuistensen, but 
differs from it by the much contracted fertile fronds. This and 
its (congener are so different from any other species of the genus, 
that it is much desirable to have a subgenus for them.

Aspidium aristatum Sw. var. suhdimorphiim Cheist Herb. Boiss. 
(1890) p. 669. 

After completing this manuscript, my attention has been 
called by Mr. T. Making to Cueist's variety suhdimorphiim which 
is mentioned in the paper above cited with following note : "La 
plante Japonaise montre quelquefois un léger penchant ver le 



MATEEIALS FOlî A FLOKA OF FORMOSA. 451 

dimorpliisine, vu (luc los frondes fertiles ont des segments bien 
plus courts et plus obtus que les steriles. J'ai une plante 
identique du continent voisin : Sud de la Chine, c. 0. Waeburg." 
So far as 1 can judge from the note given above, Polystichum 
dimorphophyllum Hayata mentioned in the present work p. 428, 
is not to be referable to Christ's variety, for the former has entire- 
ly dimorphic fronds while the latter looks like a mere form of P. 
(AspicUum) aristatum which sometimes shows the slightest tendency 
towards dimorphism. In this, Mr. S. Kodama concurs. So far as 
I am aware, the description of Christ's variety has never been 
published. 

Athyrium tozanense H^.YxT\ = Asplenium iozanens'3 Hayata Ma- 
terials for a Flora of Formosa p. 440. After finishing this 
manuscript, I have, by the suggestion of Mr. T. Nakai, once moi'e 
examined the sori of the fern, and have found that there are 
some indusia which are reflexed backwards at the apex, or on the 
middk\ It should, therefore, be properly referred to Athyrium. 

Dryopteris quadripinnata HkYA'TK—Microlepin quadripinnata 
Hayata Materials for a Flora of Formosa, p. 434. As is suggested 
by Mr. T. Nakai, the indusia of the fern are cordate, affixed to 
the receptacles and quite free on the margin. It should, therefore, 
be properly transferred to Drijopterh from Microlepia to which it 
was erroneouslv referred.

The Errantiate Polychseta of Japan. 

By 

Akira Izuka, 

BigaJcusJd, TtlgulaJmkuslii, 

Prof, of Zoology, Imperial Peers' College, ToTcijo. 



With plaies I— XXI V. 

Introduction. 

Up to tlio present our knowledge of Japanese Polycha?ta has 
been limited to the following four sources : 

1870. E. Grube. Neue Anneliden aus Japan. 

1879. E. V. Marenzeller. Südjapanische Anneliden. 

1885. W. C. McIntosh. Challenger Report. 

1903. J. P. Moore. Polychaeta from Japan, Kamtscliatka 
and Bering Sea. 

Limiting our attention to the Polychœta Errantia alone, the 
number of species belonging to that group and made known 
])\' the above mentioned autlu^rs from the Japanese waters, 
aninunts to seventy-foui- in all. Of tliis number, eighteen species 
are those tliat liave ])een previously hnown from other parts of 
the world, while tli(> rest (fifty-six) were described as new. From 
among tlic latter must ])e deducted tlio two, viz., Eunice congcsta 
Marenz. and Ghjccra declplem Marexz., which in my opinion are 



Z ART. II. A. IZUKA : 

indubitably synonymous with the older species E. indica Kinberg 
and G. goes'i Mge. respectively and which therefore have to be 
added among the former. 

Mv own researches have revealed fifty more species not re- 
corded before from Japan. Of these thirty-two seem to be new 
to science. 

Thus, there are in all one hundred twenty-four species to the 
Errantiate Polychsete fauna of Japan as at present known. 
These are referable to fourteen families and forty-five genera. 
Now, in this paper I propose to describe and to comment upon 
all the aforesaid 124 species, though in a few cases of deep-sea 
forms collected by the " Challenger " and the " Albatross," and 
reported upon by W. C. McIntosh and J. P. Moore respectively, 
I have as yet failed to acquire specimens myself and have thus 
been compelled to take recourse to merely making extracts from 
the original descriptions. 

The Polychseta Sedentaria will be dealt with in a separate 
contribution. So likewise the pelagic forms belonging to the 
families Alciopidse and Tomopteridse, of both which families not 
a single species have yet become known from the Japanese 
waters. 

The material, upon which my own studies were based, have 
been brought together mostly from within the littoral zone of the 
main islands of Japan. A small part of them was obtained by 
dredging at moderate depths (down to about 30 fathoms), and a 
yet smaller part was taken from stones, sponges, etc., brought up 
by the " long-line " from depths running down to about 450 
fathoms in the Bays of Sagami and Suruga. Most extensive and 
thorough collecting was done by myself in Misaki and neighbour- 
hood, during my repeated sojourns during a period of several 



EKllANTIAÏE POLYCHAEÏA OF JAPAN. Ô 

years in the Marine^ Laboratory of the Science College. Collecting 
was also done by nie at a number of other places, viz., Suruga 
and Izu (181)7), Isé and Shima (1808), Hokkaido and the northern 
parts of Honshiu (summer of 1899), Boshiu and Shira.osa (winter 
of 1899), coasts of the Inland Sea (1900), Shikoku (spring of 
1901), Japan Sea const (summer of 1903), Kojima Gulf (winter 
of 1900) and Hitachi (winter of 1908). 

Further, there stood at my disposal small collections made by 
the late Prof. K. Mitsukuei during his collecting trip to Kyushiu 
and Okinawa (1901), by Prof. S. Watase in Namerikawa on the 
Japan Sea coast (1905), and by Prof. I. Ljima in Sakhalin (1905). 

Here 1 wish to fulfil the pleasant duty of returning my 
thanks to all those who in one way or another rendered me aid 
in the course of my investigations. 1 am under special obligation 
to Profs. I. Ljima, K. Mitsukuiu and S. Watase for the many 
ucts of sympathies and courtesies shown towards me. To Prof. 
W. C. McInïosh (St. Andrews), Prof. Ehlers (Göttingen), Dr. W. 
WooDwoETH (Cambridge, Mass.), Dr. C. Chossland (Suez) and to 
a number of other specialists in foreign countries, 1 am indebted 
for sending me specimens or their work which were useful to 
my studies. Further 1 should not here forget to mention with 
gratitude the name of Mr. K. Aoki, collector of the Misaki Marine 
Laboratory, who expended for me no small labor in the acquire- 
ment of deep-sea Polychaeta. 

Distribution of Errantiate Polychaeta in Japan. 

Of the 124 species of Errantiate Polychaeta known from the 
Japanese waters, 84 are limited lo iliosd wtiters, while the re- 
maining 4() s[)(.'cies are found alsi) in other parts of the world. 



4 AET. II. A. IZUKA : 

Of the said 40 species, 3 are cosmopolitan, while 4 belong to 
southern, 8 to tropical, 25 to northern (iticluding (3 arctic) 
forms.* 

The 4 southern forms are those that occur in the south of 
Australia, in Kerguelen Island, and in the south Atlantic Ocean. 

Among the 25 northern and arctic species, there are 9 that 
are found along the Pacific, but not on the Atlantic, coast of 
North America, though 5 out of that number are found on the 
north European coast. The remaining 16 are those that are known 
to occur in the Mediterranian Sea and on the coast of western 
Europe, including England, Iceland as well as Greenland. Again, 
6 of the number are those that occur also on the east coast of 
North America. 

Of the 8 tropical forms, are found in the Philippines and 
in the Indian Ocean, 4 of them extending their range to Zanzibar 
and the British East Africa. The remaining 2 tropical forms are 
those that have hitherto been discovered only in the Phihppine 
Islands. The wide range of distribution of these tropical forms 
may easily be accounted for by the course taken by ocean currents 
ill different seasons along the coasts of the Philippines, India and 
Africa. Indeed, I am strongly inclined to believe that, with future 
advance of our knowledge, many more species will have to be 
added to the list of those that are common to the Japanese 
waters and the regions indicated. 

For an insight into the specific distribution of Polychaeta on 
the coasts of Japan, the reader is referred to the table given at 
the end of this chapter. In that table the localities are arranged 
in the order which, beginning at the southern part of the Japan 
Sea side, goes up northwards on that side as far as Sakhalin and 

* For names of the species see the table at the end of this chapter. 



EliliANÏIATE rOLYCHAETA OF JAPAN. 5 

then down southwards again from the Kurilcs along the Pacific 
coasts of Hokkaido, Honshiu, Sliikoku and Kyushiu, 

A few observations on tlie facts embodied in the table will 
here be in place. 

1). (rbjccra capitata, Nereis cl i/amusi £iiiä N. ezoensls are limited 
to tlie north of Oga peninsula on the Japan Sea side, while 
Laetmatonice japonica and Nereis oxjjpoda do not extend farther 
north than the same peninsula. 

2). Chloela Jiava occurs on both the Japan Sea and the 
Pacific Ocean side, but does not extend northward beyond Oga 
peninsula and Kinkwasan Island ; on the other hand it extends 
as far south as the Philippines and Indian Ocean. 

o). Nereis pelagica, N. ezoensis and Ilarmothoë yendoi occur 
along the Pacific coast of the Hokkaido and of the Kuriles. With 
the exception of the ürst, they do not come down south beyond 
Kinkwasan Island. 

4). Nereis japonica is found in Sakhalin in the north, and 
extends southward down to Sliima, occurring in all the inter- 
mediate pi'ovinces. It is j^resent in the Inland Sea also. 

')). Harmolho'c Imhrlcata is very widely distributed, occurring 
in all tlie coastal regions of Japan, from Sakhalin and Kuriles in 
the nortli to Chikuzen and Satsiima in the southernmost parts of 
Kyusliju, Polijnor (j'/nuioiKila has also a wide distribution, being 
known from Sakhalin in tlie north to as far south as Shikoku. 

G). Polynoe rexUlarla, P. clava, AphrocUta australis, Gylcera 
lesselata. Nereis Dunicrilil, N. cijUndraia, N. cult r If era, Ceratocephale 
osaical, Nereis nilc/odonid, I'Ainlcc kohicnsis, Diopalra surjolal, lùi- 
mlda caeca ;iii(l Carohia raslaiiea are limited to the Pacific Ocean 
side. Amoiigsl lliciii, Polynoe re.vlllnria extends northward beyond 
Kinkwasan Islainl, wMK' ;dl the others are not known to occur 



6 ABÏ. II. — A. IZÜKA : 

beyond that island. The southern hmit of Nereis mictodonta, N. 
cuUrifera, N. cylindrata, Polyno'è clava, P. vexillaria and Cerato- 
cephale osaioal seems to be Kyushiu Island. 

Thus, numerous species of the Polychaeta cease to occur far- 
ther south than Satsuma, so that the southern end of Kyushiu 
may be considered to constitute an important boundary line in 
regard to their distribution. 

On the Pacific Ocean side, many of the warm-sea forms 
cease to occur in the region north of Kinkwasan Island, while 
the cold- sea forms seldom extend southward beyond the same 
island ; hence Kinkwasan Island may be taken as the limit be- 
tween the two. On the Japan Sea side, Prov. Uzen seems to be 
the northern limit of Avarm-sea forms, while Prov. Osliima in the 
Hokkaido or Prov. Mutsu at the northern end of Honshiu appears 
to be the soutliern limit of cold sea forms. 

Accordingly, in regard to the distribution of marine annelids, 
the littoral zone of Japan may be roughly divided into the follow- 
ing sections and subsections : 
Sect, A, Japau Sea side. 

Subsect. 1. From Prov. Cliikuzen in Kyiisliiu to Oga peninsula in 
the north of Plonshiu. 
,, 2. From Oga peninsula to Sakhalin. 
Sect. B. Pacific Ocean side. 

Subsect. 1. From the Knriles to Kinkwasan Island in Prov. 
Rikuzen. 
,, 2. From Kinkwasan Island to the southern end of 

KyusLiu. 
,, 3. From the soutliern end of Kyushiu to Formosa. 
It win bo seen that the above sections and subsections of the 
httoral zone of Japan stands in relation to the distribution of ocean 
currents, both warm and cold, that sweep along the coasts of Japan.

ERPiANTlATE POLYCIIAETA OF JAPAN. 



Systematic. 
Family Polynoidae. 

Body flattened, with nearly parallel sides ; usually short, more 
rarely elongate. Prostomium with 2 — 3 tentacles and 4 eyes. 
Peristomium with long dorsal and ventrai cirri ; ventral cirri of the 
next following segment also elongate. Pharynx excertile ; jaws 
present. Elytra usually in 12 — 18 pairs, sometimes numerous; 
their surface more or less papillose, sometimes fringed with long 
processes along the outer border. Colouring of elytra cliaracteristic 
to most species, though liable to considerable variation in some cases. 
Nephridia open ventrall}' on pa])illa near base of parapodia. 
Bristles unjointed, generally strong, of a bright golden colour. 

Key to the genera found in Japan. 

n'. Tentacles 3. 

//. Anterior tip of prostomial lolies produced to form basal joints 
of the paired tentacles. 
(■'. Dorsal bristles nsnally present ; ventral bristles numerous 

Pdynoë. 

c". Dorsal bristles absent ; ventral bristles sparsely present 

Pohjnoëlla. 

II". Prostomium prolonged anteriorly into t-svo acuminate or rounded 
peaks. 

c'. P>()t]i dorsal aiul ventral bristles serrated for a consider- 
able ]iürtiou of their exposed leugth Harmothoë. 

c". Bristles colourless and quite transparent ; the dorsal 
slightly curved, the ventral with rows of close set spines 



ö AKT. II. A. IZÜKA : 

ill addition to n Jialf-iing of comb-like teeth supported 

on a slight shoulder ScaUseiosus. 

a". Tentacles 2, their basal joints formed by the anterior tips of 
prostoraium Iphione. 

Genus Polynoë Savigny. 

Prostominm bilobed ; anterior tip of the lobes produced to form 
basal joint to lateral tentacle on the same level as the basal joint 
of median tentacle. Dorsal ramus of parapodia decidedly smaller 
than ventral ramus, often minute, bearing bristles more slender than 
ventral liristles and which are sometimes very minute and few in 
number or are sometimes even wanting. Ventral ramus much 
larger and longer bearing a moderate number of bristles which are 
stouter and usually longer than those of dorsal ramus. Both dorsal 
and ventral rami not prolonged into a finger-like process beyond 
insertion of the bristles. Elytra from 12 to over 50 pairs in 
number. Body sometimes excessively long ; segments 26 to 100 
or more.

This is one of the most common species of the genus in the 
Japanese waters, occuring almost everywhere under stones between 
tide -marks and also at some depth under water. 

A large example consisting of 27 segments may measure 44 mm. 
in length and 16 mm. in breadth. Body thick, measuring about 
7 mm, in height at about the 15tli segment. 



EEP.ANTIATE POLYCHAETA OF JAPAN. 9 

Dorsum of a bluish gray colour, with two or three reddish, 
parallel, transverse linos running near and along the posterior 
margin of segments ; but these lines do not extend laterally to 
parapodial bases. 

Ventral surface lighter in colour and of a somewhat yellowish 
tint. 

Prostomium (pi. Ill, fig. 1) appears elongate on account of the 
fact that lateral tentacles are direct continuations of its anterior 
border. The median furrow does not reach to the posterior border 
of prostomium. Eyes of the anterior pair lie near lateral margin 
in the broadest part of prostomium ; the nuchal collar encroaches 
much upon tlie latter, so as to almost cover the posterior pair of 
eyes, which are only partially noon on tlie dorsum as indicated by 
the dotted lines in tlie figure. 

Median tentacle does not reach to tip of subtentacles ; its 
basal region is much onci'oaclied upon by the base of lateral ten- 
tacles ; the style smooth with a distinct subterminal bulb and a 
terminal filament. A similar featuie is shown l^y all other tentacles 
and tentacular cirri, which are likewise smooth tlu-oughout. Sub- 
tentacles large and thick, showing a well marked inferior ridge ; 
they are largely exposed on cacli side of tlie l)ase of lateral tentacles. 
Tentacular cin-i. with very long (Mi'riplior(\ arc thrust considerably 
outward. 

Dorsal ciiTi cxlciul latiM'ally a little beyond the bundles of 
ventral lii'istles. Each of Ihcni with a distinct suhtcnninid ])nlb, 
and a pale tcrniiiial hlaiiiciil. 

Elytra in ] J pairs, hoi ne on segments 2,4,5, and so forth on 
every alternate segment down to segment 2^) inclusive. The elytron 
is of a (lull lead gray colour, with an oval white spot over the 
point of attachment. Us sui'I'ace is niinntely |)apill(\se when seen 



10 AET. IL — A. TZÜKA : 

under the microscope, but is smooth to the naked eye, with the 
exception of the posterior part, wliich is studded on the surface 
with very distinct, though low, pale, conical papillae, and thus 
presents a somewhat pustulated appearance. There is no trace of 
cilia on edges. In some specimens the elytra are chestnut -brown 
in colour, excepting the white spot already mentioned. 

Dorsal ramus of parapodium feebly developed, bearing a series 
of pale yellowish, slender, outwardly directed bristles (fig. 2) with 
fine serration, and also a group of short, curved and serrated 
bristles (fig. 3), directed posteriorly and laterally. Ventral bristles 
(fig. 4) horny yellow in colour, directed laterally and somewhat 
posteriorly. 

First ventral cirrus nearly equal in length to ventral ten- 
tacular cirrus ; it is situated on a distinct cirriphore. The cirri of 
other parapodia are of a conical form, tapering to thin end ; they 
are short, scarcely reaching to tip of ventral rami. They show 
each a brownish band in the middle of their length. 

Ventral (nephridial) papillae commence to occur on the 7th 
parapodium, each with an aperture at the bulbous end. 

Ihe bases of anal cirri unite behind the anus, which is thus 
situated on the dorsum opposite the penultimate parapodia. 

Proboscis, when fully protruded, reaches a length about equal 
to that of the anterior 8 parapodiated segments taken together. 
It is provided with 2 strong jaws and 13 marginal papillae on both 
dorsal and ventral lips. 

Habitat : — Tomo Harbour in Prov. Bingo (!) ; Sanbongi in Prov.

This form npproachos Polijno'è gijmnonota Marenz. very closely, 
but careful examination reveals points of difference sufficiently 
warranting its specitic distinction. 

The general colour of body is much lighter than in the species 
referred to, while the parallel transverse lines occuring near the 
posterior border of segments arc of a light brownish colour instead 
of being reddish. 

Prostomiujn almost white, with two pairs of deep brown 
eyes ; tentacles, tentacular cirri and subtentacles are all of a 
l)urplisli hue. 

Ventral cirri much shorter than in Folyno'c gijuinonota ; each 
with a very faint brownish band suri'ounding it at about the middle 
of its length. 

Ventral bristles (tig. 5) are of a much lighter yellow in colour 
and ai'e more slender, with the terminal portion more strongly 
curved than in Polynoc (jyinnonoia. 

As in that species the elytra are present in 12 pairs, but their 
colouration is (|uite different. While their anterior parts are almost 
white (lig. (i), the reddisii brown coloured posterior parts show 
lighter coloured small spots scattered all over. The middle parts 
show some irregulai'Iy d ist ri bated brownish pigment spots, and the 
point of attiiclnnciit is indicated only liy an ill-dehned oval white 
spot, wliieli ill one part is in direct continuation with the white 
area. 

Two cxa,tni>Ics oT this now species were collected and pre- 
served in formalin by I'rof. 1. Ijdia in Sakhalin in the summer 
of 1900.

The largest example of this species in my hand, the one collect- 
ed by Prof. I. Ltima in Chepissani, Sakhalin, comprises 27 segments 
and measures 28 mm. in length, while the breadth is 5.5 mm. 
without, and 10 mm. with, the parapodia and setae. 

An example from Yodomi in Saga mi Bay, measures only 14 
nnn. in length and o.O mm. in breadtli exclusive of parapodia and 
bristles. 

Prostomium broadly ovate, bounded posteriorly by the fold of 
nuchal plate, and anteriorly running into the bases of median 
and lateral tentacles. It is smooth, iridescent, of a purplish pink 
colour, with a, longitudinal median furrow, and bearing four black 
eyes on dorso daterai margins. The first pair of eyes somewhat 
in front of the middle of prostomium; the second, slightly smaller 
pair nearer to the posterior border of same. Lateral tentacles 
longer than caphalic lobe ; median tentacle considerably longer 
than lateral ; all tentacles having a bulbous and deeply pigmented 
region below pale terminal filament. The tentacular cirri are 
similar in structure to, but more slender than, the tentacles. All 
these organs, as also the subtentacles, are smooth. 

The cirriphore of tentacular cirri bears, on the inner edge, a 
tuft of G or 7 slightly curved and tapering spinous bristle, which 
are directed forwards. 

Elytra in 12 pairs, borne on the segments 2, 4, 5, 7 and so 
forth on every alternate segment down to segment 23 inclusive. 
They are ovate and reniform, studded with brownish chitinous 
bosses (fig. 7) and densely ciliated on the outer and posterior 
margin. The under surface is smooth and iridescent, and 
shows a pear-shaped scar where it was detached from the

elytropliore. All the elytra overlap considerably, entirely covering 
tlie dorsum. 

Dorsal bristles long, tapering, and finely serrated (fig. 8) ; they 
are generally covered with hne mud and parasitic growths. 

Ventral bristles (fig. 9) in general of a golden hue, stout, with 
a short series of spikes on the distal, slightly thickened part of 
the shaft below apex. 

Nephridial ]iapil]ae commence to occur from the Sth ]3arapo- 
dium.

Body, consisting of 28 segments, 18 — 23mm. in length; 
the breadth 2.8 — 3.0 mm. without, and 6.0 — 6.5 mm. with, para- 
podia and bristles. 

Dorsum of a dull brownish hue, speckled with white ; elytra 
with dark mottling, ^''entrai surface pale, with some dark tints 
aljout the mouth and on the sides of the posteriormost region of 
body. The nephridial papillae in the posterior half of the body 
have the column dark and the tip whitish. 

Prostomium similar in outline to that of Polynoë sqiiamata ; 
bounded posteriorly by nuchal collar. The larger anterior eyes 
are in front of the middle of prostomium. The broad basal region 
of the median tentacle is anteriorly more distinctly separated from 
the base of lateral tentacles than in P. sqiiamata ; median and 
lateral tentacks thicker, and the bulbous region below tip"

marked by a more distinct blackish band. Subtentacles somewhat 
fihform at tip, and provided with five rows of minute papillae. 

On the dorsnin of the basal joint of tentacular cirrus are a 
single large spine and a minute tuft of tapering, serrated bristles. 

Elytra in 12 pairs, borne on same segments as in F. sqiia- 
mata. They are all more or less circular in outline (fig. 10), and 
do not quite cover the dorsum, but leave bare rhomboidal spaces on 
same. They are of a more flexible nature than in the species 
referred to, and are moreover . provided with only minute tubercles 
with the exception of the first four pairs, which sliow both large 
and minute tubercles. 

Dorsal bristles shorter, thiclcer, less tapering but more curved 
than in P. squamafa, though similar in structure. 

Ventral bristles (lig. 11) with shorter, curved or falcate tip, 
having less rows of spikes as compared with P. sqiiamata. 

Nephridial papillae commence to occur from the 8th segment, 
and continue to tlie last parapodiated segment. 

iV marked difference between P. squamata and P. clara consists 
in the facb that whereas in the fori nor species tlie body and tlic 
last parapodia are of a diminutive size, the same in the latter 
species are comparatively large.

with lateral prominences lies nearer to the posterior than to the 
anterior border ; and on these lateral prominences arc situated the 
larger anterior eyes. Posterior eyes of about half the diameter of 
the anterior, situated on the postero-lateral border of prostomium ; 
invisible from above, being covered over by nuchal fold. Both pairs 
of eyes somewhat elliptical and black. 

Ceratophore of median tentacle much larger than lateral 
tentacular ceratophores, which are prolongations of the prostomium. 
Style of median tentacle twice as long as those of lateral tentacles, 
gradually tapering from the broad base to the small subterminal 
bulb, after which it again tapers to form the short terminal fila- 
ment. Style of lateral tentacles similarly built as that of the 
median, but shorter. All the tentacles are smooth ; their colour 
nearly white with a reddish brown ring around the base of style, 
and also around the proximal region of the subterminal enlargement. 
Subtentacles stout, their tip extending a short distance beyond that 
of the terminal filament of lateral tentacles, gradually tapering from 
base to tip ; the entire organ nearly white. Tentacular cirri simi- 
lar in form and colour to those of lateral tentacles, but with 
longer style. 

There are 26 segments to the body, which is smooth on both 
dorsal and ventral surfaces. Neural depression well marked, slight- 
ly wider in about the anterior J of its length than in the posterior 
parts. Nephridial papillae commence from the 9th segment and 
continue to exist posteriorly to the 24th segment ; the first one is 
very small. 

Elytra in 12 pairs, borne on segments 2, 4, 5, 7, 9, 11, 13, 15, 
17, 10, 21 and 23. They are rather small, leaving a median longi- 
tudinal portion of the back exposed, thin and semi-transparent, 
generally oval (fig. 12), with the attachment indicated by a brown- 



EREANÏIATE POLYCHAETA OF JAPAN. 19 

ish pigment spot and situated nearer to lateral than to 
mesian border ; quite without papillae or hairs on margin. 
Each elytron, in addition to the brownish spot already alluded to, 
with minute white spots scattered over its surface, and witli 
three round pigment patches. These pigment patches are arranged 
along the longer axis of elytra, i.e., in a line making an angle of 
about 30 v>^ith the long axis of body, and of which the middle 
is larger than the other two. 

Typical parapodium (fig. 13) short; dorsal ramus represented 
by a conical protuberance, with an aciculum and about 17 short 
setose bristles (fig. 14), of which the distal half of the exposed 
portion is finely serrated, while the proximal half possesses trans- 
verse rows of fine hairs. Ventral ramus conical and truncated ; its 
distal end divided into pro-and post-setal lobes ; the former slightly 
longer than the latter. Ventral bristles (fig. 15) about 25 in num- 
ber, long, with a subterminal enlargement and a terminal hook ; the 
former provided with 7 rows of transverse hairs. 

Ceratophore of dorsal cirrus reaches to about the tip of dorsal 
ramus; its style long, provided with a brownish red subterminal bul!) 
and a long terminal filament, which takes up about J the length 
of tlie entire style. 

Ventral cirrus simple and slender, its tip reaching to base of 
the bristles.

Since I jiavc not been able to examine this species myself, I 
will give the following extract from ]\1ooee's description. 



20 AET. II. — A. IZUKA : 

Body short and broad, regularly elliptical in outline, measuring 
37 mm. in length, 15 mm. in breadth, and 6 mm. in height. It 
consists of 26 segments. 

Prostomium approximately quadrate, its anterior and lateral 
margins slightly convex, the posterior concave. Eyes of anterior 
pair about twice as large as those of posterior pair. Median tenta- 
cular ceratophore about § as long as prostomium ; style 4 times 
the length of prostomium, Avith subterminal bulb followed by a 
terminal ülament of about equal tengtli. Lateral tentacles similar 
in form to the median, but only about § as long ; the ceratophore 
only .J as long as that of the median tentacle. Tentacular cirri 
similar in form, the dorsal equalling the median tentacle in length, 
the ventral somewhat shorter. Subtentacles about as long as the 
median tentacle, rather stout, densely ciliated. 

Nephridial papillae from the 4th to the 26th segment inclusive. 

Prominent dorsal papillae occur on all segments from tlie 
2nd to the 20th inclusive, being median on the 2nd and on 15th 
to 20tli segments, but in double submedian series on Srd to 14tli 
segments inclusive. Branchial filaments occur on every segment 
from 3rd to 24th inclusive, except on the 23rd, the last elytra 
l3earing segment. On elytra-bearing segments the branchial fila- 
ments arc disposed as follows : One arises from the antero- external 
and another one from the postero- external margin of elytrophore. 
The former is unbranched ; the latter is longer, and on 
typical somites divides into a short medial and a long 
lateral Ijranch. On each parapodium there are 2 dorsal, 5 or 
6 anterior, and 4 or 5 posterior filaments, the most external 
one in each case being bifid. Essentially the same arrangement 
obtains on cirri-bearing somites, but the filaments arc here more 
numerous, longer and sometimes even trilid. There arc usually 5

dorsal ptircii)odi(il liUiinontö, of wLicli tlio one at tli<j base of 
cirrus as well as the most oxtoriial on the anterior and posterior 
faces of parapodia, are usually Irifid. • 

Parapodia stout, with ventral ramus of a somewhat com- 
pressed, obliquely truncated, conical form ; dorsal ramus represented 
by a rather prominent short tubercle on the anterior dorsal face of 
parapodium near the base. Dorsal cirri very long, their tip reach- 
ing quite beyond the setae line ; of exactly the same shape and 
colour as tentacular cirri, but with a prominent bilobcd glan- 
dular swelling at base of each. 

Dorsal bristles very numerous, deli- 
cate, capillary, with line but distinct proc- 
esses of a- length o to 4 times the 
diameter of the stem. Ventral bristles 
slightly curved, with the tip smooth 
and strongly hooked, bearded toward the 
end. 

Elytra in 12 }>airs borne on segments 2, 
4, 5, 7 and so forth, on every alternate seg- 
ment to the 23rd inclusive. They are large, 
generally beaii-shaped, strongly imbricate 
and decussate. 

Cilia form a, strong marginal fringe on 
more than ■[ the circumference.' of elytra, only 
the covered anterior portion Ijcing free of 
tlieiii. Papillae covei' the entire upper sur- 
face of elytra.

LV, p. 409; pl. xxiii, figs. 7-9. 

Tho main characters of this species may be summarized as 
follows : 

Body short, broad, elHptical, somewhat depressed, measm^ing 
26.5 mm. in length, 14 mm. between tips of bristles, 11 mm. between 
lateral margins of elytra. Number of segments 26. 

Prostomium decidedly wider than long, its lateral margin 
with prominent preocular protuberances, making this region the 
broadest part of body ; the anterior pair of eyes much larger and 
more prominent than the posterior. Median tentacle with stout 
basal piece slightly shorter than prostomium, style about 4 times 
the length of prostomium and with a subterminal enlargement and 
a short terminal filament. Lateral tentacles with ceratophores less 
than J the length of that of median tentacle, continuous with 
frontal processes of prostomium. Subtentacles with very broad, 
widely separated base, fully one half of which projects beyond the 
sides of prostomium. 

Dorsal tentacular cirrus similar in form to the median tentacle, 
Ijut with a longer filament and a slightly shorter style. 

Nephridial papillae visible so far forward as the 4th seg- 
ment, but the first three are very small, the others being exactly 
as in F. chltoniformis. Dorsal tubercles likewise as in that 
species. 

Branchiae arranged in the same manner as in P. chitoniformis, 
Ijut are larger and more conspicuous though simpler in structure 
and less in number. All branchiae rather long and slender ; totally

unbranched. None on the dorsum of para- 
podium. 

Both dorsal and ventral bristles similar 
in their arrangement to those of P. chitoni- 
fonnis, leaving the entire bearded parts of ven- 
tral bristles exposed when seen from above ; 
each bristle slender, softer and more densely 
provided with longer lateral processes. The 
latter are somewhat stouter, with a less 
number of hair rows. 

Elytra resemble those of the species in 
comparison in their number, arrangement, 
form and even in the character of their 
papillae and cilia, the chief difference lying 
in the larger size of the granules and the 
strong tendency of the papillne to become

bristles. Number of segments 20. Ventral sm^face smooth, with 
nephridial papillae in segments 8-25. 

Prostominm slightly wider than long, tliough the continuation 
of the peaks into the bases of lateral tentacles gives it a some- 
what elongate appearance. Posterior pair of eyes near the hind 
end of prostomial lateral surface ; each of them deep black, cir- 
cular. Anterior pair of eyes larger, elliptical or crescentic, black, 
situated on the widest part of prostomium. Total length of me- 
dian tentacle about 5 times that of prostomium, J of the lengtli 
being made up by the basal piece and f^ ^f same by the fila- 
mentous tip ; style with a slight subterminal enlargement. 
Lateral tentacles vary considerably in length, but are longer and 
decidedly more slender, and the filiform tip longer than the me- 
dian ; subterminal enlargement scarcely developed. Subtentacles 
about 3 times the length of prostomium, thickened basally, taper- 
ing toward the end, which bears a very short terminal fikiment. 

In typical parapodium (10th), the ventral ramus is large, 
nearly truncate or slightly angulate at the point where the deep 
brown aciculum protrudes ; ventral margin horizontal ; dorsal 
margin sloping with a slight curve to the elytrophore. The dorsal 
ramus a mere lobe on the antero-dorsal face of ventral ramus, 
supported by a slender aciculum. 

Dorsal bristles forming a large diverging tuft, but their tip 
scarcely extending beyond the end of ventral ramus, of a pale 
hay colour, capillary, bipinnate, with alternating lateral processes. 
Ventral bristles arranged in 3 supra-acicular and 5 subacicular 
iiorizontal rows, amber -coloured, relatively slender, with unusually 
long and smooth tip, which, with exception of the dorsaimost bristle, 
exceeds Uw spinous portion in length ; 4 transverse rows of spikes 
on the ventralmost bristle, on the dorsaimost.

shorter than the median ; similar in colour and structure to the 
tentacles. Tentacles, tentacular cirri and dorsal cirri are all en- 
tirely smooth. 

Dorsal cirrus with the tip extending a little beyond that of 
bristles ; ventral cirrus reaching to about the base of ventral 
bundle of bristles.

strongly serrated convex margin (PI. Ill, fig. 12) ; the posterior group 
more ventrally situated, consisting of more numerous, relatively 
slender, pointed, straight or slightly curved, pinnate bristles about 
4 times longer, and with short fine processes (fig. 13). Ventral 
bristles (fig. 14) about' 25 in number, stout, slightly bent, tlie

Remarks : I have obtained this species in abundance between 
tide-marks and also in depths down to about fathoms at Mi- 
saki and vicinity. 

The breeding season extends from March to April in Misaki. 
In matures females the colour of body approaches deep greenish 
black, while in males it is generally reddish brown. The dorsum 
of the body is marked with a brown spot on every segment, but 
sometimes these spots begin to fade away from about the loth 
segment posteriorly. The colour in living specimens obtained in 
Aomori Gulf tends to a yellowish brown.

slants off inferiorly, containing a large acieulum. Bristles in two 
dense groups ; the dorsal or smaller group consisting of slender 
forms with elongated spinous tip, ending in a slightly hoolscd 
point ; the ventral group consists of bristles, the tip of which shows 
a short terminal hook with a spur beneath and a series of relatively 
long spinous rows (Woodcut B.). 

In the 50th parapodium the general structure remains the 
same ; and between the two groups of bristles in the ventral ramus, 
there occur two especially strong bristles (Woodcut A), which have 
shafts 4 or 5 times thicker than an ordinary bristle. 

Habitat : — Off Kobe, Japan, 50 fathoms (" Challenger ").

LV, p. 417, pi. xxiii, figs. 16, 17. 

J. P. Mooee's description of this species is based on a frag- 
mentary specimen consisting of prostomium and 26 anterior seg- 
ments. Length of the fragment 26 mm. and breadth including the 
bristles at 10th segment 10.5 mm. The principal characters, as 
embodied in his description, are as follows : — 

Prostomium very short, twice as wide as long ; anterior margin 
with a deep median sulcus, on each side of which the broadly 
rounded prostomial lobes pass directly into base of lateral tentacles ; 
lateral margin strongly convex ; posterior margin nearly straight.

Eye of anterior pair at about middle of lateral faces ; that of 
posterior pair, about i- the diameter of the anterior, on the postero- 
lateral curvature of prostomium. Median tentacular ceratophore 
about equal in length to prostomium ; style about 4J times the 
length of prostomium, with slightly enlarged subterminal bulb and 
short terminal filament. Colour of median tentacle coflee brown, 
except terminal filament and distal parts of subterminal bulb which 
are white. C'eratopliore of lateral tentacle § the length of median 

ceratophore, of same shape and colour ; 
style similar to median style but more 
slender. Subtentacle a trifle longer than 
lateral tentacle, its base stout, its terminal 
half rather slender with very short terminal 
filament. Dorsal ramus of parapodia small 
but prominent, bearing a few setae. Dorsal 
cirrus very prominent, with cirriphore erect 
and curved laterally ; like tentacles in form 
and colour. Ventral cirrus arises from low 
cirriphore al)out opposite dorsal ramus.

J. P. Moore's type is the only specimen as yet obtained of 
this species. It consisted of prostominm and 26 anterior segments. 
I take the following from his description : 

Prostominm abont 1 J times as long as broad ; both anterior 
margins divided by a median dorsal groove, but this disappears 
on vertex ; anterior lobes broadly ronnded, continuons with bases 
of lateral tentacles. Eyes widely separated, small, black ; those of 
anterior pair lateral in position and nearer anterior than posterior 
prostomial margin ; those of posterior pair smaller, quite dorsal in 
position, separated from prostomial posterior border by about twice 
their diameter and from each other by about 7 times their dia- 
meter. Tentacular styles all lost, their ceratophores small ; lateral 
tentacle arises without definite demarcation from anterior prosto- 
mial lobes ; base of all tentacles deep chocolate brown in sharp 
contrast to colourless prostomiam. Subtentacles very large, 
about 6 times the length of prostominm and in their thickest 
part more than J the width of same ; their base constricted at 
the point of origin beneath prostominm ; gradually thickening 
in the first \ of their length, after that tapering to the long 
slender tip. 

Tentacular cirri lost. 

Nephridial papillae begin on 5th segment. 

Parapodia long, slender, tapering with a gentle curve to the 
slightly bilobed tip. Ventral ramus divided by a vertical cleft

into two platos ; anterior plate the larger, containing the outer end 
of a rather strongly curved aciculum. Dorsal ramus rudimentary, 
nipple-like, without bristles but with a slender aciculum. Ven- 
tral bristles perfectly colourless, delicate ; their end 
somewhat abruptly enlarged, slightly curved and 
tapering to bifid tip, of which the last terminal 
process is the larger and is slightly hooked ; proximad 
from tlie 2nd terminal process there are 9 — 14 trans- 
verse combs, the teeth of which are distally minute 
but proximal ly grow in length, exceeding the width 
of tlie bristle.

lying at the posterior border and nearer each other than the 
anterior pair, each of which occupies the lateral prominence at about 
the middle of prostomium. A well-marked median 
groove divides the broad prostomium into two lateral 
halves. Median tentacle small, subulate ; lateral ten- 
tacles somewhat shorter, but the ceratophore slightly 
longer than that of the median tentacle. Subtentacles 
small, situated inferiorly, and external to lateral 
tentacle, shorter than tlie median tentacle, smootli, 
nearly cylindrical except at the blunt conical 
extremity, wliich has a few brownish pigment just 
above the distal narrowing. 

Tentacular and dorsal cirri simple, smooth, 
filiform. Cirriphore or dorsal cirri greatly enlarged, 
forming a tumid mass. Ventral cirri very short, 
subulate, not reaching tip of parapodium. 

Proboscis with 9 papillae on each lip. Two elon- 
gate papillao on each side at about the middle of pro- 
truded proboscis. Jaws amber-coloured, slender, sharp. 

Elytra in 12 pairs, pale, rather thick, friable, 
without any cilia or processes, beautifully though not 
regularly reticulated, the margin alone granular. 

Farapodia in about 23 pairs, their fleshy part 
largely developed. Dorsal ramus a soft, conical and 
minutely granular elevation, wholly devoid of bristles. 

Ventral ramus much developed, forming a long, 
sliglitly tapering process with bifid tip ; bearing one 
Ventral bristle of q^ two loug, stifl", light amber- colourcd bristles.

Body elongate -ovate, posteriorly more distinctly narrowed 
than anteriorly. It measures 24 mm. in length and the breadth 
4 mm. without, and 9 mm. with, parapodia and bristles. Number 
of body segments generally 39, exceptionally 1 or 2 less. 

Prostomium (PL V, fig. 1) exhibits as usual two pairs of eyes ; 
those of the anterior pair are situated laterally and under the 
anterior peaks, so that they are invisible from the dorsal side, 
while those of the posterior pair are situated near the postero- 
lateral margin. Median tentacle is long, while the lateral ones 
are short and scarcely reach half the length of the former. Each 
tentacle, both median and lateral, consists of a basal region and 
of a terminal style, which exhibits a distinct swelling, the sub- 
terminal bulb, before terminating in the filiform end. The style 
is provided with sparsely distributed, clavate papillae (PI. Y, fig. 
2), except in the filiform end which is smooth. Subtentacles arc 
elongate and tapering, and are beset with rows of somewhat 
truncate clavate papillae. Tentacular as well as dorsal cirri agree 
with the median tentacle in form, and are in possession of a 
considerable number of clavate papillae. Dorsal tentacular cirri 
are about equal in length to the median tentacle, while the 



EREANTIATE POLYCHAETA OF JAPAN. 47 

ventral ones are somewhat shorter than the latter. Dorsal cirri 
extend laterally nnd somewhat posteriorly beyond tips of ventral 
bristles. 

Elytr;i in la pairs borne on segments 2, 4, 5, !.. 

21, 23, 2(), 29, o2. Tlie anteriormost pair of elytra, which are 
of a rounded outline, are generally dull-white in colour, so that 
they stand in prominent contrast with the general dark coloura- 
tion caused by ii-regular accumulations of pigments, thus giving 
to the animal a very bizarre appearance as if it had a pair of 
large duU-wliite eyes. 

The remaing elytra are ovate-reniform or obliquely ovate in 
shape. Tlieir jiosterior as well as lateral margins are fringed with 
fine papilhe. 

The dorsal ramus of parapodium is but feebly developed and 
bears a, series of yellowish bristles (T^l. V, fig. 3) Avith rather 
distinct spinous nnvs and a wc^l-marked smooth part at the free 
end. The ventral bristles (PL V, fig. 4) are light yellow in 
colour, with rows of long spikes and bifurcated terminal hooks. 
The ventral cirrus scarcely reaches in length to tip of ventral 
parapodial ramus. Nephridial papilla? commence to occur on the 
7th parapodium. 

Proboscis Jong, reacliing a lengtli al)out equal to that of the

Trotia Padi, Chepissani and Lake Bousset in Sakhalin (Prof. J. 
Ijima). 

Bemarl^s : —This species occurs all along the eastern and 
western coasts of Japan from Sakhalin to Kyushiu. I have 
found no marked differeîice in size according to the latitudes. 
Thus a southern example (from Kyushiu) measured 27 mm. in 
length and 4 mm. in breadth, while a northern example brought 
back by Prof. I. Ijtma from Tretia Padi (Sakhalin) measured 30 
mm. and 4 mm. respectively. An example from the Gulf of Mi- 
yazu (.Japan Sea) measured 20 mm. in IcTigth and 3 mm. in 
breadth. The largest specimen obtained near the Misaki Marine 
Laboratory was 27 mm. long and 4 mm. broad. 

hi the Gulf of Miyazu, where, as on the Japan Sea coast 
generally, the ebb and flow of tide is not considerable, the species 
can be collected from among algae or from stoTies brought up 
from a depth of a metre or two. In Misaki it occurs abundantly 
under stones and among the oel-grass, algae, etc., near the low 
water mark. 

The species is very active and restless when disturbed, and 
when taken on haîid, it wrio-ales about violentlv, shedding ofl' 
the elytra and frequently even breaking up into fragments. It is 
a rather difficult matter to keep the worm alive in confinement. 
Under circumstances it swims making an undulatory motion with 
the body, but soon sinks to the bottom. 

In the montb.s of March aud April are commonly met with 
individuals with masses of eggs under elytra. The eggs are of a 
slightly pinkish colour and are agglutinated together by a trans- 
parent mucous secretion, so that they do not readily fall off. In 
PI, \[, fig. 1 is shown a female specimen whicli was obtained in 



EEEANTIATE POLYCHAETA OF JAPAN. 49 

Misaki, on April 2nd, 1905, and was kept alivo in a vessel for 
a few days. It carried a mass of embryos nnder the elytra, from 
the 8th posteriorly to the penultimate segment. On April 4tli 
some of the embryos began to swim about freely in the vessel, 
leaving the shelter of the mother. At first the free-swimming 
embryos were in an early trochophore stage, exhibiting a weakly 
developed ring of cilia, but soon this developed into the charac- 
teristic state that enabled the larvae to swim about very 
actively.

PI. V, figs. 5—8. 

An unique specimen of this species was obtained by Mr. 
K. Yendo in July 1903, at Shimushu, Kurile Is. It was found 
on Arshro hifidvs that was brought up from a depth of 4 fathoms. 

On careful examination the specimen was found to differ 
from tlie foregoing species in some important characters, though 
there existed n general agreement in the features of l)ristles, in 
th(! peculiar position of anterior eyes, and in the relative lengtlis 
of tentacles and subtentacles. 

Compared with tyi^ical //. imhrlcaia, the prostominm (fig. 5) 
is more angular and tlie posterior pair of eyes placed at a more 
mesiad ])Osition. The basal ])ortions of the median tentacle and 
of tentacular cirri are quite stont in proportion to their slen- 
(](')• Hhsdes; the swellings or bulbs at the base of their terminal 
liliforin portions are vci-y slight : tlie ends of subtentacles are 
greatly attenuate(l and finis foi'in filiform terminal pieces like 
tliose of the tentacles (^r tentacular cirri. 

The dorsal cirrus is of a similar length as that of //. im- 



50 AET. II. — A. IZÜKA : 

bricata, but the pigment band at the base of the distal swelhng, 
as also another faint band situated above that swelling, is black. 
The transition of the swelling to tlie terminal filament is abrupt, 
presenting an appearance as if there existed an articulation at the 
boundary (fig. 6). 

The tentacles and cirri are all entirely smooth. 

The dorsal (fig. 7) and ventral (fig. 8) bristles closely resemble 
those of H. imbricata. 

The 15 pairs of elytra are all similarly coloured and destitute 
of marginal fringes.

Several examples of this species were obtained at different 
times in Misaki and vicinity. 

The largest specimen in my hand measures 46 mm. in 
length, and 12 mm. in breadth including bristles and parapodia ; 
it consists of 40 segments. The smallest one, consisting of 39 
segments, is 30 mm. long and 9 mm. wide. 

On the posterior border of each segment, just at the base of 
each parapodium, there exists a small semicircular lamella 
directed postero -laterally. This lamella lies posterior and internal 
to the small ventral (or nephridial) papilla, and extends a little 
beyond the anterior margin of the succeeding segment. 

The colour of body in living specimens is grayish yellow, 



ElUiANTIAïE POLYCHAETA OF JAPAN. 51 

which coloui' changes in alcohol into a straw yellow or a slightly 
reddish yellow. In a specimen obtained from a muddy shore, the 
margin of elytra, tlie pear-shaped process upon them, and the 
tips of dorsal bristles are all tinted black. 

Prostomium (fig. 0) roundly liexagonal, strongly arched, and 
divided into two lateral halves by a median furrow. Its length is 
about equal to tlie breadth. The anterior border is deeply notched 
by tlie insertion of the basal joint of the median tentacle. The 
nnterior larger eyes are placed in the middle of lateral mar- 
gins, and the posterior smaller eyes at a little distance from the 
posterior margin. Median tentacle nearly o times as long as 
prostomium ; tlie lateral ones about as long as or a little longer 
tlian same. All these tentacles provided with round-tipped 
cylindrical papillae of a deep brownish colour. Subtentacles about 
4 times the length of prostomium, and covered with very short 
papillae. The dorsal pair of tentacular eirri is about equal in 
length to the median tentacle, while the ventral pair is somewhat 
shorter than same. All tentacular cirri are papillatcd like the 
tentacles themselves. The basal piece of tentacular cirri has one 
or two bristles. 

Parapodium somewhat longer than half the breadth of the 
segment to which it belongs ; the dorsal ramus has, on its in- 
ferioi' horder, a linger-like ])rocess, in which the aciculum is in- 
serted ; the ventral ramus has, on its superior border, a similar 
l)r()cess, from which the bristles arise. Dorsal cirri long and

body as well as the prostomium, leaving only a few pos- 
terior segments uncovered. The lateral and posterior half of 
elytra is beset with pear-shaped papillae of a dark colour. These 
papillae are distinctly observable with the naked eye ; with the 
aid of the microscope one sees in addition numerous small conical 
papillae arranged in rows that run antero- posteriorly but diverge 
somewhat as they approach the posterior margin of elytron. The 
lateral and posterior margins of all elytra are provided with 
somewhat long and filiform papillae. 

The dorsal ramus of parapodia bears a large bundle of strong 
bristles (fig. 10) of a brownish dark colour. The bristles of the 
ventral ramus are about 40 in number ; they are all of a pale 
yellow colour. They are smallest in ventralmost position (fig. 
11, a) and increase gradually in size dorsally (b) ; those in the 
upper part of the group arc of a form with bifurcated tip (c), 
while a few in dorsalmost position are of a form with finely 
tapering end (d). 

The first ventral cirrus is about equal in length to the me- 
dian tentacle, while those of other parapodia are conical with 
finely tapering end and do not reach the tip of the ventral para- 
podial ramus they belong to. 

Xephridial papillae are observed from the 6tli or the 7 th 
segment posteriorly. 

Anal cirri long, being about equal in length to that of the 
posterior 11 segments taken together. 

The breeding season of this species in Misaki extends from 
August to September.

I liavo not been able tu secure 
a specimen of this species. 

Prof. McIntosh's description of 
the species, based on a dried speci- 
men, may be summarised as follows : 

Elytra and dorsum mottled all 
over with dark brownish pigment, the 
prostomium being especially dark. 
Tentacles as well as tentacular and 
dorsal cirri have numerous and some- 
what long cilia, each with slightly 
bulbous tip. The elytra are studded 
all over with small spines, their 
posterior and outer borders showing 
numerous and rather long cilia. 

Both dorsal and ventral bristles 
are of a pale straw yellow colour. 
Dorsal ranms of parapodium bears 
a serries of bristles with a smooth, 
sharp point. The serrated rows are 
distinct, though the spines are not 
long. 

Ventral l)ristles have bifid tip 
and well-marked spinous rows. The 
secondary ])r(K'ess forms an acute 
angle with the lung axis of tlie liuuk 
un the tip : tliu smuuth purtion l)e-

tween the latter and the commencement of the hispid rows is long. 

According to McIntosh, this species somewhat approaches 
Tlarmothoé lamellljera, but should differ from it in the absence of 
pear-shaped processes on elytra, which are also apparently less 
minutely spinous. Further, the dorsal bristles in H. lamellifera 
do not show so long a smooth region at the tip, and the secondary 
process or spur of the inferior series should show a different angle. 

Habitat : — Dredged off Yokohama, Japan, in 5 to 50 fathoms

Body small and rather elongate, 13 mm. long and 3 mm. 
broad, comprising 39 setigerous segments. 

Prostomium furnished with four very distinct eyes, two of 
which are placed wide apart at its posterior border, while those of the 
anterior pair are longer and are situated slightly in front of the lateral 
prominence. The latter are fully seen only from the side. Paired 
tentacles rather thick at base but tapering at end. Subtentacles short, 
with filiform tip. Dorsal cirri somewhat slender ; their tip long 
and filiform. Ventral papilla a well-marked cylindrical process. 

Elytra occur in 15 pairs on segments 2, 4, 5, 7 21, 23,

nearly cylindrical papillae, and show on the posterior parts of their 
surface and along the edge a somewhat dense growth of cilia, longest 
and most abundant along the outer Ijorder. Toward the inner 
posterior Ijorder of elytra the papillae become shorter, more 
sparse and clavate in shape.

Bipeniiato-penicillate setae (fig. 9) are found only in the upper 
half of the truncated end of parapodium ; serrulate setae occur 
numerously in the lower part of the same ; spine-like setae, light 
yellowish brown in colour, are strong and have no terminal appen- 
dage (fig. 8), and are arranged in a row upon the end surface of 
the parapodium. Aciculum, one in each parapodium, is situated 
about one-third way up the vertical height of this. A tuft of long 
and soft hairs of a golden yellow colour arises from the upper 
half of the parapodium end. They are very long sometimes reach- 
ing to a length of 40 mm. or more. 

Elytra are borne on the segments 2, 4, 5, 7, 9 &c. on every 
alternate segment down to the posterior end of the specimens. 
The first elytra are large and elliptical in shape ; they meet in the 
median line ; the second ones roundish in shape, and smaller than 
the first, being only about half as large. On the lltli segment 
the median zone of the dorsal surface left uncovered by its elytra 
is about twice as wide as the diameter of the elytra themselves. 

Proboscis strikingly large and strongly muscular. Each of its 
dorsal and ventral lips is provided in the middle with a long 
papilla of a bluish-white colour. The edge of each lip is lined 
wdth a row of tooth-like papillae. Jaws two pairs, a dorsal and 
a ventral. Each jaw provided with a row of 17 small teeth in 
addition to the very strong apical fang.

maxinuim tliiekness 4 mm. 

Jn tlie specimen which is preserved in alcohol, the dorsal 
surface in tlie anterior one-eighth of the body is brownisli, dis- 
tinctly marked off laterally from light yellowish parapodia ; and 
in tliis part of the dorsum there are seen very fine transverse 
striations, which obscure the demarkation lines between segments. 
Posteriorly the colour changes into light yellowish djrown and 
finally into light-yellow near the posterior end of body, showing 
liowever a brownisli median line traceable nearly to tlie posterior- 
most end, indicating the course of the dorsal median blood vessel. 

The N'entrai surface is pale yellowish. In the median line of 
this side there runs a, brownisli longitudinal band marking the 
course of the ventral nerve chain. The band shows a slight con- 
striction at eacli intersegmental position. Moreover, the band is 
somewhat l)i'oadens anteriorly, and terminates abruptly just ix'hind

A large example at my hand measures 47 mm. in length, 
20 mm. in transverse diameter at the widest part, consisting of 42 
segments, and with 15 pairs of elytra. The posterior region of 
body, which as usual in the group is distinctly narrowed, bearing 
a proportionally larger number of segments. 

Dorsal felt extremely tough and dense, and coated with 
grayish mud. The long and abundant lateral hairs give the worm 
a woolly aspect, and their colour is of delicate green. 

Prostomium roundish, having a front a short blunt conical 
tentacle, immediately behind which are 2 pairs of eyes, the anterior 
pair being wider apart than the posterior. They are small but 
distinct black points, entirely sessile. 

A series of light bronz- coloured great setae (or spines) are 
found projecting outwards amongst the hairs. The tips of these 
setae do not taper much, but end in somewhat broad points (fig. 
4), which are covered with minute chitinous spikes, so that the 
surface is rasp-like. The inner tufts of setae, which curve r(3und 
and backward amongst the felt of the dorsum, are broad at the 
base but tapers to slender tip, also marked by slight roughness 
or points. The ventral setae anteriorly are for the most part 
(fig. 5) dart-shaped, but in some the tip is entire (fig. ö). 

Dorsal cirri long and finely tapered toward the tip, which is 
slightly clavate.

In the absence of my own observations on the species, 
the following extract is made from YIcIntosh's description. 

Body broadly fusiform, measuring about 100 mm. in length, 
and about 50 mm. in breadth including setae and parapodia. 
Number of segments 47. 

Prostomium somewhat triangular, with a slender elongated 
median tentacle, to the tip of which is attached a pear-shaped 
process by the narrowed end. Eyes small, on prominent pe- 
duncles. Subtentacles separated at their base by a frontal 
tubercle, smooth and glistening to the naked eye, but under 
the microscope their whole surface is seen to be covered with 
pointed cuticular papillae. Behind the ocular peduncles a multi- 
lobate process occurs, extending laterally and then anteriorly along 
the outer border of the peduncles. 

A typical spine-bearing segment (19th) bears dorsally a 
series of boldly curved, dull golden setae, which are rather broad

and inferiorly flattened but taper to 
the simply pointed extremity, the great- 
er part of the latter region being 
minutely nodulated. The next inferior 
group of bristles consists of a tuft of lust- 
rous brown spines (setae glochidiae), 
about 22 mm. in length and slanting 
backward. The recurved fangs of the 
spines are usually in 5 opposite, or nearly 
opposite, pairs. 

Ventral setae (sec the accompany- 
ing woodcut) have lustrous brown shafts, 
each of which lias a long and curved 
hook at the distal end, followed after 
an interval by a series of chitinous 
processes arranged in a pectinate 
manner. 

Elytra in 20 pairs, borne on seg- 
ments 2, 4, 5, 7, 1) and every alter- 
nate segment down to 25 and 28, 
then on ev(,'ry tliird segment down to 45, 
entirely coxering the dorsum. They 
are smooth, parchment-like and slightly 
ji'idescent, showing under tlie micro- 
scope granular rows radiating from

Body, consisting of 40 segments, measures 48 mm. in length 
and 15 mm. in breadth. 

Prostomium somewhat triangulai- ; median tentacle, slender 
and elongated, with peculiar enlargement on tip. Lateral regions 
of prostomium very prominent. Ocular peduncles globular ; eyes 
indistinct. Elytra in 10 pairs (McIntosh says the number of elytra 
varies from 15 to 18 pairs), borne on same segments as in typical 
Laetmatonice producta. They are more delicate than in the 
typical species, exhibiting under the microscope a finely granular 
condition with radiating lines. No dorsal felt exists. 

Dorsal spines considerably larger than in the typical species, 
and Avhile the shafts are large and flattened, the terminal portions 
are relatively small, presenting a distinct curve in certahi views. 
Number of fangs in the terminal portion varies, but is mostly o or 
4 (fig. 7). Slender l^ristles from the inner dorsal tuft overlapping 
the elytra are represented in PI. IX., figs. 8 — 9 ; longitudinal striae 
are very distinctly marked in these bristles, and numerous 
chitinous prickles surround the shaft.

The arrangement of cirri seems to be the same as i]i the 
tyi)ic;d species. Nothing is of Tnore diagnostic value than the 
condition of the ventral cirrus, whicli forms a very minute filiform

Genus Sthennlepis Willev. 

Both the genera Thalenessa and Leanira are cliaraeterised by 
tlie presence of a very small tentaculum inipar growing directly 
from prostomium without a ceratophore. The compound bristles 
of the former belong to a variety of falcigerons type with biden- 
tate appendages ; those of the latter are spinigerous. 

Whereas, Sthenelals and Sthenolepis are both characterised by 
the presence of a long tentaculum impar borne upon ceratophore 
which is provided with a pair of spatulate appendages. The 
compound bristles of Sthenelais are falcigerons like those of Thale- 
nessa, while those of Sthenolepis are spinigerous as in Leanira.

90 ART. IT.^ — A. IZUKA : 

The first elytron is small, rounded and quite smooth. Elytra 
rapidly increase in size posteriorly, and almost cover the dorsum 
in the anterior parts of body. They are soft, whitish, slightly 
translucent ; those in the anterior third of the body are quite 
smooth on both surface and margin. Posterior to the anterior 
third of body, the fold on the outer margin of elytron presents 
a series of simple and very slightly tapering papillae, but 
these are usually invisible to the naked eye. Minute examination 
shows that the outer border in anterior elytra is very prettily 
marked with regularly arranged areolae. 

The second parapodium (which carries the first elytra) puts on 
the character of tlie posterior to a greater or less extent. The 
dorsal ramus has a group of very long papillae (about five in 
number). Only the bristles nearest the body are distinctly serrated. 
Ventral ramus has bristles with the usual canaliculated tip, though 
these are more slender than those which follow. 

The third parapodium bears a long and characteristic cirrus, 
which stretches forward considerably beyond tip of the first parapo- 
dium in a straight line. The cirrus is an elongated, smooth, tapering 
process, and has a globular enlargement at base on the external side. 

In fally developed parapodia the ventral bristles are long, as 
represented in PI. X, fig. 8. 

A well marked branchia, richly ciliated inferiorly, occurs on 
every parapodium, and bears ventrally at base a diverticulum-like 
process. Ciliated pads occur one under the branchia, a second 
long and a third broadly clavate or fan- shaped one on the dorsum 
of parapodium.

Body slightly narrowed in front, nearly uniformly broad for 
the greater part of its length, though tapering again at the posterior 
end. It measures 78mm. or more in length, and its widest part 
about 6 mm. in breadth including parapodia. 

Prostomium with moderately elongated tentacles ; the median 
tentacle shorter than others in adjacent position. The base of 
external tentacles is carried farther forward than in Onupkis 
conchylega ; the anterior tentacles are similar to those of 0. 
conchjlega ; the 2 tentacular cirri about as long as in that 
species. 

The first pair of parapodia are directed forward as in O. 
conchylega ; with both dorsal and ventral cirri and a setigerous 
lobe. 

The bristles (fig. 1) have somewhat abruptly curved tip; 
with hooked end, and with a broad, pointed process immediately 
beneath it. The guard extends considerably beyond the Jiooked end. 

Branchiae begin to occur on 8th segment as a small process 
on each side ; on the 9th they are well developed and long, but 
simple ; they continue to be of the same sliape nearly to the 
posterior end of body, and on the 2nd in front of preanal 
segment they still equal the parapodium in length. At the 20tli 
parapodium the Ijranchia is more than twice as long as tlie dorsal 
cirrus.

margin of tbe tuft, followed by a series of rather short bilid 
Ijristles, the terminal hook of these being a little longer than tbe 
one below it. The entire extremity is guarded. 

The next region of the body commences at the fifth segment, 
and is characterised by the elongation of dorsal cirrus, and by 
the conversion of ventral cirrus into a flattened glandular scute. 
The first scute is the smallest, and from the second jjosteriorly 
the scutes rapidly increase in size, so that between the fourtli 
and the tenth segment they attain maximum size, but a^ain to di- 
minish somewhat in size posteriorly.

tentacles. 

The first 4 setigerons segments distinguished from the others 
liy tlieir greater length, as well as by the longer and more 
slender cirriform process of parapodia. The first segment is the 
longest of all, and in its anterior parts the widest ; the succeeding 
three segments become successively shorter, thus gradually ap- 
proaching typical form, which is short, wide and depressed with 
nearly flat dorsal and ventral surfaces. Anal segment somewhat 
funnel-like, with a pair of crowded, long, slender caudal cirri. 

Branchia simple, appearing as a direct continuation of the base 
common to it and dorsal cirrus. It is erect and just reaches tlie 
middle hne of back when best developed. Eraiichiae appear on 
5tli parapodium as a slender filament eiualling the cirrus in 
length, l)ut posteriorly they quickly increase to a considerably 
greater length, and then continue to exist without change except 
undergoing a slic^ht decrease in size as far the 110th segment. 

Hooked bristles are confined to the first tln-ee pairs of para- 
podia ; their end with 3 processes, of which the terminal one is tho 
longest ; guard prolonged into an acute tip which reaches far be-

about 20 mm. in lireadth at tlio widest region. Number of segments 
u]) to 430. In tlio anterior region of body the segments are highly 
arched dorsal ly, and gradually become low-arched toward the poster- 
ior end. Tlie colour of the living animal is black with strong metallic 
iridescence, and usually the 6tli and 7th segments are lighter 
coloured.

Maxillae deep brownish black ; the forceps gently curved, being 
3 times as long as their posterior processes ; the great dental 
plates with 4 teeth on the left, and 5 on the right ; the left 
unpaired plate with 5 teeth ; the paired lateral plates with 3 teeth

forceps and their posterior appendages taken together, rod-like, 
with white jaw-plates, the cutting edge of wliich is indistinctly 
serrated. 

This annelid secretes a pale whitish mucous tube, in which 
it lives. Once I have kept it alive for more than 4 weeks in 
an aquarium at Misaki ; it has secreted, in the course of one 
night, a pretty thick tube in which the body was entirely 
concealed.
