Locality : One specimen, labelled " Purple violet Eunice," taken from Buoy, Galle. 



The dorsum of the 6th segment is pale ; segments streaked longitudinally 

 violaceous; antennae and cirri banded violaceous and white. Segments 178, incom- 

 plete behind; length 100 millims. ; width (ventral) over the feet 8 millims., over the 

 seta? 10 millims. Antennas nearly smooth, quasi-articulate, cirri smooth ; tentaculum 

 impar and submedian antennae equal to seven segments, but the former ends bluntly 

 and has probably been longer ; dorsal cirri long throughout and smooth. 



Branchiae begin as a bud on the 7th segment (5th foot), plurrfilar on the 8th, in 

 subsequent segments acquiring 14 filaments; in the 17th segment the branchial stipe 

 is shorter than dorsal cirrus, in the 28th it is equal to the cirrus, and in the 48th 

 longer than the cirrus (Plate IV., fig. 102). The general distribution of the branchiae 

 and the number of filaments will be understood from the following enumerations, the 

 Roman numerals giving the number of the segment : 



VII, VIII. , XVII. , XXVIII. , XL VIII. , LX, LXXL, CXIV., CXL., CLXX. 

 1. 4. 13. 13. 14. 14. 14. 12. 10. 5. 



In the anterior segments there are 8 or 9 dorsal capillary setae and about 20 

 compound falcigerous bidentate setae in the ventral fascicle (Plate IV., fig. 103) ; the 

 two-pronged ventral acicular setae commence at the 35th foot (Plate IV., fig. 104); 

 comb-setae (scalprate setae) more numerous posteriorly, with about 12 denticulations. 



Jaws : P. II. 6 ; L. II.-6 ; L. III. (the unpaired sinistral jaw-piece)-7 ; R. IV.-9 ; 

 L. IV. -4. 



This species belongs to that section of Eunice characterised by multifilar branchiae 

 and long dorsal cirri extending from end to end of the body. The type of this section 

 may be taken to be E. tentaculata, Quatrefages (1865, i., p. 317), from South 

 Australia (Bass Strait, Tasmania). Another example is the original E. clseyi, Baird 

 (1870), from Queensland (not E. clseyi, McIntosh), which is synonymous with 

 E. acquahilis, Grube, 'Schles. Ges.,' 1877, Breslau, 1878, p. 24, from Cape York. 



Eunice murrayi, McIntosh.

(1.) Station XL V., off Panadure (Pantura), depth 25 fathoms, inhabiting a tube on 

 the under side of a Spondylus valve ; a polynoid was in the same tube. 



Prostomium wide, frontal border deeply emarginate ; antennae moniliform ; the 

 tentaculum impar longe-articulate, stretching back over 18 segments; gills with 

 12 pinnae; guards of compound setae slightly projecting; total width in anterior 

 region, 4 millims. The tube which accompanies the specimen is encrusted with sand 

 and Foraminifera. 



(2.) South-east Cheval Paar ; occurring with Eunice antennata.
