The single specimen is 25 mm long by 10 mm wide and consists of 30 setigers. It is pale save for dark brown setae. There are only 13 pairs of elytra; it is probably immature. Earlier, Melaenis tropicus Treadwell, from the West Indies, was re- ferred to the genus Hermione (Hartman, 1938, p. 127) ; it is herein con- sidered identical with the older H. hystrix. Distribution —In warm waters of both hemispheres. Family Polynoidae Halosydna leucohyba (Schmarda) Polynoé leucohyba Schmarda, 1861, pp. 153-154, 5 figs.

Collections —A 12a-39 (1); A 20-39 (10); A 25-39 (1); A 30-39 (2); Color variations range from iron gray to pale rust. In one specimen there are large flat pustules on elytra, ranged in an irregular row along the posterior margin of anterior pairs. Distribution —West Indian regions; the commonest polynoid in in- tertidal zones. Lepidonotus humilis Augener Augener, 1922, p. 40; 1933, pp. 194-195. Collections —A 12-39 (2); A 25-39 (1). The collections include mature individuals of both sexes. A complete male is 11.5 mm long, 3.75 mm wide, and consists of 26 setigers; it is white in the posterior half. An adult female is 10 mm long, the posterior half dark green because of crowded ova. They are present from the ninth setiger to near the end. Elytra are strongly fringed at the outer lateral edge; their surface is marmorated and provided with many small flat- headed, or irregularly topped, papillae. Distal ends of notopodia and 10 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT neuropodia have many small papillae. Neurosetae are distally bidentate and have 3 or 4 rows of spinelets at the thickened region. Augener’s origi- nal preliminary description (1922, p. 40) was later enhanced (1933, p. 194). The type specimen was said to be only 9 mm long, but no mention was made of its stage of development. Distribution West Indies; intertidal. PThormora taeniata (Ehlers) Polynoé taeniata Ehlers, 1887, pp. 51-52, pl. 10, figs. 1-8. Lepidonotus (Thormora) taeniatus Seidler, 1924, pp. 92-94. Collection —A 15-39 (2). ‘Two mature individuals, consist of 26 setigers, measure to 17 mm long by 4.5 mm wide, without parapodia; the general shape is rectilinear. The ovigerous region is dark green, present from the tenth setiger to near the posterior end. The dorsum is rust colored, save the elytra of the first pair and anterior half of the second pair, which are pale. The prostomium is distinctly lepidonotoid, the frontal processes continuous with the pro- stomial lobe, not sharply marked off as first shown (Ehlers, 1887, pl. 10, fig. 1). The anterior eyes, however, are near the anteroectal margins of the lobe as originally shown, and the posterior pair are far back, normally covered by the straight peristomial membrane. Prostomial antennae and palpi have the proportions first shown. Elytra number 12 pairs, have entire margin, and are uniformly pale russet save for a small, pale spot over the elytrophoral scar. They overlap slightly in the middorsal line, but leave exposed most of the setal and neuropodial length. They are elongate oval, in anterior-posterior direc- tion. The surface of most is smooth save for micropapillae, but the first few pairs are characterized by large, tall, yellow, blunt spines, especially in the area over the elytrophoral scar and at the posterior margin. These tall, coarse spines are most abundant on the first pair of elytra, where they are distributed over the entire surface, but well separated from one another; by the fourth pair they are not only smaller and less conspicuous, but limited to the area over the scar and at the posterior margin. Farther back the surface is comparatively smooth, but has micropapillae over all. Notosetae consist of two kinds, as characteristic of Thormora,; the spinous setae are coarse, distally bluntly pointed, disposed in a whorl around the smooth setae; the latter are much longer, slenderer, include longer and shorter ones, just as first shown. Neurosetae are coarse, yellow, distally entire, with 5 or 6 rows of transverse spinelets; the anteriormost have usually a large yellow tooth at the distal end of the spinous row, as shown for J. taeniata (Hoagland), but those in the middle and ventral NO. 3 POLYCHAETOUS ANNELIDS Te portions of the series lack this character. Parapodial lobes are short, dis- tally truncate. These specimens agree with the original account in all but two re- spects—the prostomial processes are continuous with the prostomium, not set off by a transverse line, and elytra are ornamented with some tall, yellow, blunt spines instead of pustules as shown in the original account. Ehlers’ description was based on a single specimen, only 12 mm long. Distribution.—West Indies, in a few fms. Family Polyodontidae Eupanthalis oculata, new species Plate 1, Figs. 5-8; Plate 2, Fig. 12 Collection.—A 14-39 (1 anterior end). An anterior end of 42 segments measures 21 mm long (without everted proboscis). The prostomium consists of 2 well-separated lobes, with median fissure; eyes number 4, the anterior pair very large, dark, occupy most of the prostomial lobes; the second posterior pair are very small, near the posterior margin (pl. 2, fig. 12). Frontal paired antennae are clavate; the unpaired one is inserted at the posterior margin of the prostomium and extends forward to beyond the prostomial lobe; it has a slender terminal filament. Palpi are long, slender, about 3 times as long as the prostomium. Elytra are thin, translucent, oval, with entire margin, colorless save for a narrow brown crescent at the inner edge. The attachment is far lateral, at the outer third or fourth. The first segment has dorsal and ventral cirri resembling the paired prostomial antennae but slightly longer; it lacks setae and probably acicula. The second segment resembles those farther back, has well-developed neuropodial lobe, ventral cirri, and first elytra. The notopodium is suppressed, as typical of the genus, and its ventral cirri are about twice as large as those following. The third seg- ment has dorsal and ventral cirri, resembles those farther back. Jaw pieces are yellow, the 4 main fangs falcate, the upper piece has 6 teeth right, 5 left, the lower has 5 teeth right, 7 left. In addition to the long, median processes on dorsal and ventral sides, there are 6 elongate, soft papillae, both above and below, on each side. Setae of the second segment (first setiger) are slender, slightly genicu- late, terminate distally in a long, fine point. From the next there is a pos- terior series of some coarser setae which are increasingly more conspicu- ous farther back; they are aristate. A typical parapodium is provided with a heavy, yellow aciculum, a dorsal fascicle of slender, spinous setae in which the spines are widely separated (pl. 1, fig. 8), about as many 12 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT thicker, spinous aristate setae (pl. 1, fig. 6), 4 to 6 heavy, yellow aristate setae (pl. 1, fig. 5) from which the terminal portion has dropped off in nearly all instances, in the middle portion of the fascicle, and geniculate spinous setae (pl. 1, fig. 7) in the inferior part of the fascicle. Bushy- topped or brushlike setae are altogether lacking. Spinning glands are first present from the ninth setiger, continued to the end of the piece. E. oculata differs from known species of Eupanthalis most notably in the possession of its enormous anterior eyes and the character of its supe- rior neuropodial setae. Holotype—AHF no. 72. Type locality —South of Cape la Vela, Colombia, in 21-22 fms (A 14-39). Distribution —Colombia, Atlantic side. Panthalis, sp. Collection.—A 4-39 (an anterior fragment). A single anterior end of 37 segments, measures 24 mm long. The dorsal surface is marked with reddish brown in the form of broad, trans- verse bars across the segments; a large part of the elytral surface is covered with a similar pigment. Palpi, peristomial cirri, and the first 2 pairs of elytra are marked with many fine dark specks, ranged in transverse lines on the palpi. Ommatophores are elongate oval, set off from the prostomi- um by constricted bases, with conspicuous, lenticulated eyes in their distal half. The smaller, sessile eyes are at the anterior third of the prostomium, in front of the insertion of the median antenna. The latter has its origin at the midlength of the prostomium; its style extends distally to the ends of ommatophores. The paired antennae are inserted ventrally, posterior to the base of the ommatophores. The first elytra are small, oval, the second a little larger; both are pale, with small dark specks. Farther back they increase in size but con- tinue circular to oval, with entire smooth margin and have large, rust- colored blotches instead of fine black specks. The elytrophore is far to the side, near the lateral edge. The first segment is reduced to a pair of long, forward-projecting, parapodial lobes with thick, tapering, subequal dorsal and ventral cirri, each speckled with dark pigment and provided with small dorsal and ven- tral tufts of a few fine, pointed setae. The second parapodia have the first pair of elytra, a ventral cirrus resembling that of the first, and slender, pointed setae in both notopodia and neuropodia, but spinous, geniculate setae in the inferior part of the neuropodial fascicle. From the third, setae NO. 3 POLYCHAETOUS ANNELIDS 13 resemble those farther back. A typical parapodium has a slender fascicle of penicillate setae above, about 6 heavy, aristate setae, and a full fascicle of spinous, geniculate setae below. Notosetae are fine, few in number, inconspicuous throughout. Notopodia are sheaflike, at the anterior base of neuropodia; the latter are deep, truncate. Digitiform branchiae are first present from the ninth setiger, gradu- ally increase in length but continue as simple processes to the end of the piece. Family Sigalionidae Eusigalion lewisii (Berkeley) Sigalion lewisii Berkeley, 1939, pp. 326-328, fig. 23. E. hancocki Hartman, 1939, pp. 59-60, pl. 12, figs. 141-145, 148-152. Collection —A 24-39 (1). A single specimen agrees fully with others from the eastern tropical Pacific. Distribution —FEastern Pacific, in warm waters; Venezuela. Leanira grubei (Treadwell) Sthenelais grubei Treadwell, 1902, p. 187, figs. 10-13. Eupholoé grubei Treadwell, 1939, p. 197. Hartman, 1942, pp. 106-107. Collections —A 7-39 (1); A 38-39 (2). Composite setae are tapering, pointed, lack canaliculae. The type spec- imen has been re-examined and referred to Leanira (Hartman, 1942, p. 106). Distribution—Puerto Rico; Tobago Island, British West Indies; Caledonia Bay, Panama. Leanira incisa (Grube) Pl. 1, Figs. 1-4; Pl. 2, Figs. 9-11 Sthenelais incisa Grube, 1878, pp. 518-520. Sthenelais simplex Ehlers, 1887, pp. 60-63, pl. 13, figs. 2, 3, pl. 14, figs. 1-6; Treadwell, 1902, p. 187. L. simplex Augener, 1906, pp. 106-107, pl. 1, figs. 16, 17. Augener, 1918, pp. 107-108; Monro, 1930, p. 70. Collection.—A 4-39 (1). In this single specimen the prostomium has 4 circular eyespots, on the anterior half, near the base of the median ceratophore (pl. 2, fig. 10), thus differing from the original accounts. The median antenna has a pair of lateral ctenidia, as first shown by Ehlers (1887, pl. 13, fig. 2). The first 14 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 3 pairs of elytra are oval; therafter they are sharply incised at both inner and outer lateral margins (pl. 2, fig. 9) ; in posterior segments, however, the inner lateral margin is rounded (pl. 2, fig. 11). Parapodia are strongly fringed, especially in anterior segments (pl. 1, fig. 2). A single long pa- pilla on the notoacicular lobe projects beyond the others. The acicular lobe is conical (pl. 1, fig. 1). Neurosetae are of two kinds, including a small anterior-superior fascicle of spinose setae (pl. 1, fig. 4) and whorls of composite setae with canaliculate appendage and pointed tip (pl. 1, fig. 3). Distribution.—Originally described from Congo, Africa, it has been reported from West Indian seas; this record extends the range to Cale- donia Bay, Panama. Psammolyce arenosa (delle Chiaje) Fauvel, 1923, pp. 106-107, fig. 40. P. floccifera Augener, 1906, pp. 109-113, pl. 2, figs. 24-30. Augener, 1933, p. 194. Collection A 4-39 (2). Distribution—Mediterranean and western Europe; West Indian seas. Sthenelais articulata Kinberg Kinberg, 1855, p. 387; 1910, p. 28, pl. 8, fig. 38. Collection.—A 22-39 (1). An accessory ventral cirrus is present through 5 segments. Multiar- ticulate hooks occur only in the superiormost series of neurosetae. The ventralmost hooks are bounded below by a row of fringe. In the closely related S. tertiaglabra Moore (1910, p. 395), to which S. hancocki Hart- man (1939, p. 65) belongs, an accessory ventral cirrus is present only on 2 segments; multiarticulate hooks occur in number through the neuro- podium, and there is no fringe on the ventral side of neurosetae. ‘These and other differences will be discussed more fully later. Distribution—Brazil, tropical West Indian region; central eastern Pacific, north to southern California.
