P0LYC1LETA. 27 U 



Marenzeller, the buccal segment is three times as broad as long, and the tentacular 

 cirri equal it in length. This feature may be attributed to the method of preserva- 

 tion. The second point relates to the lateral ceratophores which according to the 

 author of the species are nearly twice as long as the submedian. This may be an 

 individual variation, an abnormality, or the distinction of a local race. Unfortunately 

 the length of the lateral ceratophore, in proportion to the total length of the antenna, 

 is not stated. The calcareous ends of the laminse ventrales of the jaws show an 

 emarginate frontal border, agreeing closely with von Marenzeller's figure.

Localities : Several specimens, Station XXV., f mile west-north-west of Foul 

 Point, Trincomalee, 8 fathoms. Station XLIIL, off Kalutara (Kaltura) ; one specimen 

 in company with Pectinaria tubes. Station XLV. , off Panadure ; several specimens. 



The tubes, 65 millims. to 70 millims., are faintly ringed at intervals of about 

 2 millims., and sometimes the annulation shows the double crescentic arrangement 

 described by Grube. In the Ceylon specimens, the branchiae commence almost 

 constantly on the 22nd foot (23rd segment) ; once I found the first gill on the right 

 side on the 21st foot. 1 only observed aciculas with simple blunt rounded apices 

 protruding from the first modified parapodium, but in the second foot may be found 

 bidentate aciculae and a compound seta as figured by Crossland, as well as acuminate 

 forms. This species is closely allied to H. tubicola, of which it is clearly a local 

 representative. A full account of the hyaline tube which is guarded internally by 

 valves has been given by Mr. Arnold T. Watson (" On the habits of Onuphidse," 

 ' Trans. Liverpool Biol. Soc., ; vol xvii., 1903, p. 303).

 (1.) Station V., off Chilaw, Gulf of Manaar, 11 fathoms. In this specimen 

 branchiae commence on the 19th foot, becoming successively 3-filar, 4-filar, and 6-filar, 

 decreasing behind and leaving about 30 abranchiate posterior segments ; they are 

 inconspicuous, barely stretching halfway to the mid-dorsal line ; body flattened and 

 ribbon-like behind the anterior branchiferous region; length 75 millims., width 

 5'5 millims. 



(2.) Galle, 14th February, 1902. Fragment of anterior region; gills begin as a 

 bud on the 16th foot and rapidly attain the maximum of 5 filaments ; calcareous caps 

 of laminse ventrales present ; pale collar on the fourth setigerous segment ; prostomial 

 tentacles with violaceous annulations ; body-colour of preserved specimen dark olive- 

 green ; width over the setae, 5 millims.
