LAGISCA OCULESCENS, new species. 



Plate 47, figs. 1-7. 



Type. — Cat. No. 189-1;), U.S.N.M. Length of specimen, 25 mm. 

 Number of somites, 38. Number of scales, 15. Greatest width, 7 

 mm. Body attenuate posteriorly. 



Head (fig. 1) somewhat more than twice as long as broad, pro- 

 longed anteriorly into minute lateral peaks. Median tentacle broken. 

 Lateral tentacles attached below median, extending a short distance 

 beyond lateral lobes of head. Palps about three times as long as 

 head, longitudinally striped. Tentacular cirri, two pairs, reach- 

 ing two-thirds of length of palps, borne on long basal portion. Eyes, 

 two pairs, completely coalesced, forming roughly S -shaped markings 

 on the dorsal surface of the head. 



Elytra (fig. 2) roughly ovate, with ruffling edge; crowded into al- 

 most vertical position posteriorly by the pressure of the dorsal 

 setae. Median posterior area of elytron covered with ornate golden- 

 brown spines (fig. 3). 



Parapodia (fig. 4) with noto- and neuro-podia, each drawn out into 

 bluntly pointed processes laterally. Dorsal cirri long, sharply at- 

 tenuated at end, borne on basal portion. Ventral cirri small and 

 short. 



Setae of three kinds; all light yellow. Dorsal (fig. 5) stout, with 

 blunt naked tip and provided with minute serrations throughout re- 

 mainder of length. Ventral two kinds: many (fig. 6) slender, biden- 

 tate, provided with long barb-like teeth; a few (fig. 7) biden- 

 tate, and provided with needle-like serrations. 



Type either from Jolo Anchorage, Jolo, or from Kopoposang Light, 

 Macassar Strait, 400 fathoms hard bottom. 



Genus PANTHALIS Kinberg. 



PANTHALIS MELANONOTUS Grube. 



Panthalis melanonotus Grube (1878), p. 4S, pi. 4, fig. 1. 



One specimen of this species was found. The first seven pairs of 

 elytra were lacking, so that it was impossible to determine to what 

 extent they had overlapped. It agreed in all respects with Grube's 

 description, except that it possessed small paired tentacles situated 

 immediately beneath the ommatophores. Number of somites, 90. 



Collected at station D5209, Taratara Island, 20 fathoms, green mud 

 bottom. 



PANTHALIS ADUMBRATA, new species. 



Plate 46, figs. 9-14. 



Type.— Cat. No. 18944, U.S.N.M. Length of specimen 48 mm., 

 incomplete. Length of a complete paratype 63 mm. Number of 

 somites, 53 ; scales, 24 pairs. Width, 12 mm.
