ON SOME MARINE INVERTEBRATA

VKOU THE

QUEEN CHARLOTTE ISLANDS*
BY J. F. WIIITBAVES.

The whole of the specimens belonging to the species enumerated in
the following lists were collected by Dr. G. M. Dawson and his brother,
Mr. Bankine Dawson, in the summer season of 1878, on the eastern
coast of the Queen Charlotte Islands, along its whole extent, and off
the noi'thorn extremity of (Iraham Island, between Virago Sound and
Noi'th Island.

With the exception of a few and for the most part common litLoral
forms, which were found to be very generally distributed, it has been
thought desirable to place on record the exact locality and station at
which each specien was obtained, by dredging or otherwise, although
the doing of this lias necessarily involved some reiteration which
might otherwise have been avoided.

For valuable notes on the echinodermata and corals, and for the
descriptions of now species of Archaster and Solaster, the writer is
indebted to Prof. A. E. Verrill, of Yale College. Mr. W. H. Dall, of
the Smithsonian Institution, Washington, has kindly examined and
identified some of the smaller and more critical species of moUusca.

The Crustacea collected by Dr. Dawson on the coast of Vancouver,
as well as at the Queen Charlotte Islands, have been reported on
separately by Prof. S. I. Smith, of Yale College.

A curious fact, established by those collections, is the occurrence at
the Queen Charlotte Islands of several species of marine mollusca
previously found only much further to the southwards, and hitherto
supposed to be peculiar to the Californian fauna. The most notable of

* The (rroup thus named lies to the North-west of Vancouver Island, in the Province of
Britiih Columbia, and is included between N. lat. S4» 15), 51>« 55* ; W. long. 131° 21, 133" 5'.

those are Leda cceldta, Hinds ; Bryophila setosa, Carpenter ; Mitrormrpha
filosa, Carjientoi" ; Odostomia straminea, Curpontor ; Lamellaria Stearnsii,
Dflll; Volutella pyriformis, Cav\wnior ; Amphissa versicolor, Dall.

AmoiiiLf the corals, too, the only locality previously known for
Parncyathus caltha was Montei-oy.

Th6 followin/:j w a list of all the specios rccognisod so far, but tlio
foraminifera, bydrozoa, and polyzoa, of which a ratlior extensive series
was procured, have yet to be studied :

SP0N(lir)iT5.

Grantia ciliata, Fabricius. Dredged at nio«leratc depths and at various
localities on the coast of the Queen Charlotto Islands, also at
Vancouver.

Tethea, Sp. undt. Not yet examincil. Houston-Stewart Channel, in
from 15 to 20 fathoniw, tv/o lino specimens.

IIydroida.

Allopora venusta, Verrill. Houston-Stewart Channel, in from 15 to 20
fathoms, five specimens.
This species is placed in this division on the authority of Prof. Vorrill.

Anthozoa.

Balanophyllia elegans, Verrill. With the preceding; also in 20 fathoms,
ai the month of Cumshewa Harbour, several tine specimens.

Paracyathus caltfia, Verrill. Same localities and depths as the last
species.

"Numerous specimens, of various sizes and varying consiilerably
in form, from narrow and nearly cylindrical to broad cup-shaped." —
Verrill.

Ophiuroiuea.

Ophioglyplia Lutkeni, Lyman. Abundant at Dixon Entrance, in 111
fathoms.
" Those arc larger than the original specimen described by Lyman,
and show some variation. On the basal poi-tion of the arms there are
two tentacle-scales. The radial-shields are long oval, with the inner
end pointed ; they only touch each other in the middle. Mouth-shields
broad spear-shaped, the outer end broad and a little prolonged, obtusely
rounded ; the side angles prominent and rounded ; the inner end trian-
gular, with slightly incurved sides. Arm spines three, acute, the
upper one considerably longest. The arms, towards the base, are high,

8

with a Hiight dorsal ridge. Color, ash-gray above, white below."—
Verriil.

Ophwpholis Careyi, Lyman. Mouth of Cumshewa Harbour, in 20
fathoms, not very common.

" Agrees with the description of the original type."— Verriil. The
correctness of the identification of this and of the preceding species
has also been corroborated by Col. Lyman, to whom specimens of both
were senf.

Amphiura urfica, Lyman. Virago Sound, in from 8 to 15 fathoms.

Several small specimens. Determined by Prof. Verriil, who

remarks concerning them :

" They have few small spinules on the plates near the edge of the

disk. The under arm-plates are squarish, with a notch on the outer

edge, as in the original specimens."

ASTERIOIDEA.

Asferias epichlora, Brandt. (?) Littoral, and apparently not very
common.

" Rays five. Spines of dorsal surface evenly distributed, nearly
equal, rather long, somewhat enlarged and sulcate at the tips, and sur-
rounded, above the base, by a thick wreath of minor pedicollarias.
Adanibulacral s]»ines in two rows, slender. Ventral spines longer,
stouter, obtuse, sulcated at tips, foi ming tour close rows."— Verriil.

Asferias ochracea, Brandt. The most common of the littoral species
collected.

Asterias fiexactis, Stimpson. Found sparingly at or near low-water
mark.

Leptasterias. ('• Near L. MuUeri and Z. tenera") Virago Sound, in
from 8 to 1.5 fathoms, several small and poorly preserved
specimens.

" Bays five, slender. Adambulacrrl spines slender, mostly two to a
plate. Lateral and dorsal spines slender, not crowded." — Verriil.
Pycnopodia helianthoidea, (Bi-andt.) Stimpson. Below low-water mark

in Skidegate Inlet, but rather uncommon.
Solaster Stimpsoni, Verriil. Sp. nov. Beach at Eamsay Island, five or
six specimens.

" This species is allied to S. ende^a of the North Atlantic. It has a
smaller disk and longer rays, usually ten in number. One of the larger
dried specimens has the radius of the disk 1-25 inches; of the rays 4 to
4-50 inches. Color of the disk and b."se of rays, above, light red ; lower

surface yellowlHh. The rays nro long, round, regularly ta
Upper Hurfaco covered with cluHterH of small blunt spinules or paxillro,
mostly six to eight in a group, on the I'ays; and ten to twelve on the
disk, where they are more crowded. In Hnuvllor specimens there are
fewer spinules in the dusters. These spinules are larger, stouter,
more obtuse and nioi-e numerous than in S. endeca. On the lower side
the iiitorbrachial spaces are smallei- than in S. endeca, with lewer
piates, each of which bears a close group, usually of four or five taper-
ing s])inules, rather larger than those of the dorsal surface, and much
stouter and fewer than the corresponding spinules of S. endeca. The
plates forming the lowoi' margin ol'the disk are less prominent than in
8. endeca; and each bears a transverse group of about twelve to sixteen
spinules, similar to those of the sides and under surface of the rays.
Along the grooves each adambulacral plate bears on its inner end two
small, short, tapered spines, which form a longitudinal row, and outside
of these a transverse row of about eight, much longer and larger, tap-
ered spines, with rough, blunt tips. These are stouter, less acute and
less rough than those of *S'. endeca. The oral plates bear six strong and
rather long spines at the inner eiul, the middle ones longest. These
ai'B stouter and not so long as those of S. endeca.

" This is, possibly, the form called Asterias endeca, var, decemradiata
by Brandt (Solaster decemradiatm St imp). But Brandt gave no
description whatever." — Verrill.

Solaster Dausoni, Verrill. Sp. nov. Virago Sound, in from 8 to 15
fathoms, one specimen.
" Of this species I have seen but a single dried specimen, with
twelve rays. Kadius of the disk, -80 of an inch; of the rays, 2*10. It
has the general appearance and proportions of S. endeca, as seen fi'om
above, but resembles Crossaster papposys beneath. The plates of the
uppei- surface and their clusters of spinules are even smaller, more
numerous and more crowded than in the former species, thei-e being
usually ten to twelve minute and short spinules to each plate. The
]>lates, when denuded of spines, are small, rounded and convex. The
marginal plates are prominent, and each bears a prominent transverse
group of numerous, small, slender spinules, forming two rows of about
twelve to fourteen each. The interbrachial spaces, beneath, are very
small and narrow, with few plates, each of which bears a group of
three or four slender spinules. These spaces are very much smaller
than in S. decemradiattis, and still smaller as com])ared with S. endeca.
The adambulacral plates bear a longitudinal group of three, rather
long, slender spines on the inner end, and outside of these a transverse
group of four or five, scarcely larger ones. The oral plates bear six

long, hliint »pinoH, the middle oiioh longoHt. Tim adambulucriil HpinoM

to ('. papposus." — Vorrill.

Cribrella Ueviuscula, Stimpnon. Common, from low-water mark to 15 or
20 fathoms.

Dermaster mbricatus, Porrier.

(~=Asteropsi8 imbricata, Cirubo, 1857. A. Agassiz, North
American Startishos, 1817 ; p. 106, pi. xv., figs. 1-7.)
A rather common and brilliantly coloured, littoral species, found at
several localities.

Asterina rniniata, Brandt. (Sp.) Near low-water mark, abundant
locally.

Mediaster a'qualis, Stimpson. Beach at Ramsay Island, one fine
specimen only.

Archastcr Dmvsoni, Vorrill. Sp. nov.

'' A large species, in form resembling .1. tniuispinus of the North At-
lantic. Radius of the disk, •(i5 ; of rays, 4 inches. The rays are long,
flat, regularly tapered. The upper surface is loosely covered with
small tubercles, bearing only circular groups of very minute, short
paxdlie toward the margins of the rays ; but along the middle region
of the rays and over the disk bearing a long, tapering, acute central
spinC; surrounded at base by a circle of small pr.xil'a^ ; between the
plates there are, over the whole surface, numerous pores. Along each
ray, toward the marginal plates, there ai-o, at irregular intervals, singu-
lar groups of small incurved spinules ; usually three or four clusters,
each cluster consisting of a row of three or four sjjinules, form one group ;
the ends of all the spinules converge to a pore in the centre of the
group. The upper marginal plates are small but prominent, and each
bears a long, rather stout, acute, ei-cct si)ino, surrounded at base by a
group of slender, unequal spinules. The lower marginal plates mostly
boar three long and largo divergent spines, the upper one largest, and
rather longer than those of the upper plates; between and around their
bases there are slender spinuloe. The adambulaci-al plates bear upon

what longer than the anterior, and rather more pointed at its extremity
below. Umbones broad and depressed ; beaks compressed laterally,
eroilod, moderately prominent, curved forwards, and placed a little in
advance of the middle. Posterior area ill-detined, indicated obscui-ely
by an oblique and abrupt compression of the valves above and behind a
rounded ridge or swelling, which runs in the dii-ection of a line which
might be drawn from the hinder side of the beaks to the posterior
termination of the ventral margin. This ridge or prominence is

in the middle of tlu! shell. Lunulc none ; lunular region abruptly and
obliquely compressed or inflected.

Surface marked by coarse, crowded and irregularly disposed, concen-
tric wrinkles or raised striae. As viewed under an achromatic micros-
cope, with an inch and a half objective, the shell is seen. to bo covered
in places with an exceedingly minute, angular and irregulai- network
of raised wrinkles and radiating striae.

Colour: — Bark rusty-brown on the exterior of the valves (])ossibIy
duo to the ferruginous nature of the mud or sand in which it lived),
whitish on the beaks and umbones. Interior, porcellanous white.

Dimensions of the only specimen collected: — Length, 10 lines;
height, scarcely 1 ; thickness, 5 lines.

specimens in Mr. Ball's possession arc from Alaska and Monterey, so
that the species appears to have a wide range on the west coast of
North America.
