described. M'Intosh's specimens were similarly deficient 

 (1900, p. 414). 



The palps appear to be long, slender, and tapering, like 

 those of Stheiielais limicola, Elders. The posterior end o£ 

 the annelid is slender and has apparently two caudal cirri. 



An examination of the complete head will determine 

 whether this form shall remain in the genus Sthenelais. 



Sthenelais limicola, Ehlers, 1864. 



One specimen was taken along with numerous examples of 

 OpModromus flexuosus, Delia Cliiaje, in 56° 48' N., 1° 19' E., 

 in 94 m. It is a deep-water form, ranging from 30 to over 

 400 fathoms, and is never found between tide-marks. 



The body is small and incom))lete. All the scales have 

 been lost, and the head is in a bad state of preservation. 



Sthenelais Jeffrey sit, M'Intosh, 1876. 



Specimens of this annelid were taken from the seas to the 

 north of the Shetland Islands. It has been recorded only 

 from the Atlantic Ocean to the west of Ireland, and has still 

 to be found in the North Sea. It would seem to prefer a 

 deep-water habitat. 



The largest of the specimens (incomplete) are about 35 mm. 

 in leno-th. The body is long and narrow, and tapers gently 

 towards the posterior end. No eyes are visible in any of tlie 

 specimens. The proboscis has ten irregularly conical terminal 

 papillae dorsal ly and ventral ly.
