Percy Moorr University of Pennsylvania. The Canadian Arctic Expedition, from 1913 to 1916, yielded a very few leeches. These are contained in four bottles sent to me along with a few bottles of planarians by Mr. Frits Johansen. There are but two species, already well known from the seas of northern Europe but as they have not been recorded previously from American waters it seems worth while to publish a notice of the extension of their known geographical range. Both belong to the family Ichthyobdellide. Family ICHTHYOBDELLID-. Abranchus scorpii Malm. This species, with which A. brunneus Johansson is probably identical, is represented by nineteen specimens varying from 14 mm. to 40 mm. long and from -8 mm. to 2-7 mm. in maximum diameter. All of the specimens are nearly terete or only very slightly flattened, the young ones most so. The greatest diameter is shortly behind the middie from which it tapers both ways but unequally. The anterior end is more slender and more gradually tapered but there is no distinct division into two regions. In the better preserved specimens both oral and caudal suckers are large, thin and widely expanded, the oral relatively less so on the larger examples. On none of the specimens is the annulation strongly marked, the somites being dominantly triannulate with the secondary annuli more or less well differentiated. Thus in the widest part of the posterior region the neural or middle primary annulus is enlarged and clearly subdivided into secondary annuli which, however, are smaller than the entire first and third primary annuli so that we have the formula (b! + b?) (b'+ 6°). In the an- terior region development of annuli has gone less far, being recognizable only in the neural annuli. The formula is, therefore, A! <(b3+ b‘)>A?. The sensille and larger non-segmental cutaneous sense organs are developed on annulus 6? and a few smaller ones on 6!, b? and 6°. The fresh colour as described in the collector’s notes is ‘‘a dark purple- brown main-color; strongest red in shape of segmental bands. The two ter- minal suctorial discs pale inside with the brown muscles shining through. Eyes black.”” The preserved specimens differ considerably chiefly as a result of size and fading. Those from station 42™ are most deeply pigmented, being of a dark reddish brown above, paler below. The margins of both discs, two transverse bands on the oral disc and radiating lines and marginal spots on the caudal disc, several transverse bands on the body, and the region about the anus also paler. Those from station 49% are pale reddish brown above with whitish transverse bands especially conspicuous laterally on the first annulus (A!) of each somite. All of the parts indicated as pale reddish on the specimens from 42" are on these whitish. Small individuals are nearly colourless. The sensille and non-segmental sense-organs are clear white and very. conspicuous on dark specimens. The three pairs of eyes are black and arranged as figured by Johansson. The caudal eye-spots also are black, small and arranged in a circle at the central ends of the pale marginal spots. . Following is a list of the specimens with labels and collector’s notes quoted in full: 4c Canadian Arctic Expedition, 1913-18 “Station 41x, C.A.E. On just dead Cottus scorpius L. Bernard harbour, Northwest Territories. End of August, 1915. F. Johansen, coll.” Four small ones. “Station 42m, C.A.E. On just dead Cottus scorpius L. Bernard harbour, Northwest Territories. Dark purple. F. Johansen, coll.’’ Three full grown specimens. “Station 49g, C.A.E. On skin of dead Cottus scorpius L. Bernard harbour, Northwest Territories. June 15,1916. F. Johansen, coll.’ Twelve specimens of various sizes. Oxytonostoma typica Malm. A single specimen having exactly the appearance of Malm’s figure of Pontobdella granulifera with which this species is probably identical. Length 22-5 mm., maximum width (behind middle) 4 mm. The body is strongly fusiform and in the posterior region slightly flattened but strictly terete anteriorly. Much enlarged caudad of the middle and tapered to ‘the very narrow anterior region which immediately behind the oral disc measures only one-tenth of the greatest diameter. Posteriorly it tapers less, the width at the anus being about one-fourth of the maximum. Oral sucker small and very deeply cupped. No eyes. Caudal sucker neither deeply concave nor strongly expanded, being about one-half the maximum diameter. Somites in the middle region are strongly marked, as though the body cavity were extensively developed and subdivided by disseppiments, as in earthworms. Twelve such are very distinct but the constrictions fade out toward the caudal end. There is here no trace of annulation. In the slender anterior region the somites are less distinct but there is some trace of annulation which extends onto the head also. On the ventral surface of the anterior half of the posterior region are six pairs of rather conspicuous, low, rounded elevations situated just behind the constrictions. In the center of each appears a small orifice (nepridiopore?). The integument presents a peculiar shiny surface as though covered by a thick cuticle like a tapeworm on which no papille, granules or sensille are visible. It is of a dirty brownish color, stained dark purple or slaty at the slight constrictions. The peculiar appearance is probably due to the stretching of the integuments as a result of extreme gorging of the digestive tract with blood. “Station 41, C.A.E. Bernard harbour, Northwest Territories. 3-5 fathoms. July 20, 1915 (dark purple). F. Johansen, coll.’’ One specimen. Platybdella sp. The Victoria \Jemorial Museum at Ottawa also contains a fish leech from the Neptune Expedition. It is poorly preserved and cannot be determined by me. Length 13-5 mm., width at middle 1-4 mm., diameter of caudal sucker 1-5mm. Noeyes. Caudal sucker prominent, thin and repand. No eye-spots. Somite appear to be triannulate with traces of the secondary furrows. “From Sclerocrangon boreas (Phipps). Neptune Exp. 1903-04.” Report of the Canadian Arctic Expedition, 1913-18. _VOLUME VIEI:.
