DISCOVERY REPORTS 



bidentate bristles of the first four feet are as figured by Augener. The comb chaetae 

 (Fig. 45, a) have about 12 rather long closely set teeth. The capillary bristles (Fig. 45, b) 

 have a distinct narrow border along both 



edges. There is a pair of large yellow 

 subacicular bidentate hooks (Fig. 45, c). 

 The gills begin on the 4th chaetiger and 

 there are only three pairs in all. They 

 have a long thick stem with a crown of 

 spiral filaments. 



Regarding the jaws, I cannot with my 

 present material discover the shape of 

 the carriers; otherwise they resemble 

 Augener 's figure. The dental formula is 

 9 — 10 : 10 + 7 — 8. 



I have rather doubtfully referred these 

 two fragments to Augener 's species.

Description, Two fragments incom- 

 plete posteriorly. The larger measures 

 28 mm. by 4 mm. including the feet and 

 has 35 chaetigers. In spirit there are no 

 colour markings. There is a pair of 

 globular anterior tentacles. All the re- 

 maining tentacles are short and thick. 

 The outer laterals are spindle-shaped 



with massive tentaculophores : the inner laterals are more slender and subulate. They 

 reach to the anterior border of the 2nd chaetiger. The median tentacle is a little shorter. 

 The stout tentacular cirri are inserted on the anterior border of the ist segment. 



The first three pairs of feet are much enlarged and carried forward beneath the body. 

 In addition to a stout dorsal cirrus and a small conical ventral cirrus, there are a small 

 papilla on the inner and anterior face of the chaetal lobe and two papillae, a ventral 

 and a dorsal, at the apex of the chaetal lobe. Behind the first three modified chaetigers 

 the feet are of the usual onuphid shape (Fig. 46, a). The dorsal cirrus is rather short 

 and thick, just surpassing the end of the chaetal lobe. The ventral cirrus is a rounded 

 lobe and it is transformed into a pad by the 6th chaetiger. The cirriform prolongation
