TYPHLOSCOLECIDAE 89 



The upper end of the latter is produced into a kind of peak and overhangs the lower 

 end. 



The feet (Fig. 27) are very large and prominent and the pinnules small in com- 

 parison. On the first two feet I can find no trace of a rosette either on the pedal trunks 

 or on the pinnules. On the third and subsequent feet at the point where the trunk of 

 the foot at its apex merges into the pinnule there is a rosette gland on both dorsal and 

 ventral rami. It has the appearance of a small black oculiform spot and beyond it 

 towards the edge of the pinnule is an area filled with brown granules. 



I can see no spindle of fine tubules such as is sometimes visible in hyaline glands; 

 moreover, its position in close apposition to the trunk of the foot and the fact that it 

 faces outwards towards the edge of the pinnule, and not inwards towards the foot, 

 strengthen the presumption that it is a true rosette and not a hyaline gland. On the 

 lower part of the pinnule of the ventral ramus is a cupuliform chromophil gland which 

 varies considerably in size in the diff"erent specimens. I can find no trace of what Rosa 

 calls an aciileo. 



All the species of Johmtonella with a tail hitherto described have rosettes on the 

 trunks of the first two feet or an aculeo or both. These structures are absent from the 

 present species. 



Chamberlin has described three species of Tomopteris, T. mnatans, T. eura and 

 T. I'dmra; Treadwell has also given an account of two further species, T. opaca and 

 T. tentacidata. Unfortunately the nature and position of the pedal glands are not 

 specified with sufficient precision for these species to be capable of inclusion within 

 Rosa's system of classification. 



Note. This species is named after Dr Stanley Kemp, the distinguished leader of the 

 expedition.

Remarks. These specimens are conspecific with the example described and clearly 

 figured by Benham from the Ross Sea. I share Benham 's doubt whether they should 

 be referred to Wagner's North Atlantic species, and unfortunately I have no example
