EUNICIDAE iSS 



In regard to the jaws M. II have four to five teeth, M. Ill are bidentate, and not 

 unidentate as Ehlers records: the second tooth is small and easy to overlook. M. IV 

 are unidentate. The lower jaws are striated in front. 



Remarks. Apart from the speckling which cannot always be seen in preserved 

 specimens, the outstanding features of this species are the more or less globular pro- 

 stomium, the characteristic capillary bristles of the middle and hinder regions, and the 

 presence of two teeth in M. III. 



Lumbrinereis sp., near impatiens, Claparede. 



Occurrence. WS 756 (i). 



Specific characters. A large incomplete specimen measuring no mm. by 3 mm. 

 The head is conical, and several grooves run up from the second buccal segment to the 

 mouth. In the front region the feet are fairly well preserved and the hinder lip is 

 conical and longer than the front lip. The acicula are yellow. In the front region the 

 chaetae consist of winged bristles and simple crochets with long guards. In the middle 

 and hinder regions the guard of the simple crochets is much shorter, and the capillary 

 bristles disappear. In the present specimen they persist at any rate as far as about the 

 80th chaetiger. In the middle and hinder regions the feet are macerated and collapsed, 

 and it is impossible to see whether there is an increase in size of the hinder lip of the 

 foot in the posterior region. The jaws differ from those of a typical impatiens: M. II 

 have five teeth; and M. Ill are unidentate, and not bidentate. 



Remarks. In the form of the head and of the bristles this specimen agrees with 

 impatiens. It difi'ers to some extent in the structure of the jaws, and unfortunately the 

 shape of the hinder feet cannot be ascertained. It may represent a new species. 



The Chilean L. bifilaris, Ehlers, has a similar arrangement of bristles, but the pedal 

 lips in the hinder region become greatly elongated. 



L. antarctica, mihi, is similarly devoid of compound crochets, but it has black acicula, 

 capillary bristles only in the first 10 chaetigers, and jaws with three teeth in M. II. 



Genus Augeneria, Monro 

 Head conical and with three small tentacles at its hinder edge partly hidden in a 

 crescentic groove between the prostomium and buccal segment, as in Aglaurides. Dorsal 

 and ventral cirri and gills absent. Bristles winged capillaries and simple and compound 

 crochets. Jaws as in Lumbrinereis with a pair of mandibles and three pairs of plates. 



Augeneria tentaculata, Monro. 

 Monro, 1930, p. 140, fig. 52 a-k. 



Occurrence. St. 599 (i); WS 212 (i); WS 236 (i); WS 773 (i). 



Specific characters. One specimen is complete and measures 170 mm. by 4 mm, 

 at the widest part for 159 chaetigers. The head is of a rounded oval shape and there are 

 no eyes. Of the three tentacles lying in the nuchal groove at the back of the head the 

 median is a little larger and stouter than the rest. The second segment forms the lower 

 border of the mouth.
