450 A. E. Verrill— Marine Nemerteans of ISfeiv England. 



truncate at the end. Otherwise it agrees very well with the larger 

 specimens. The cirri are, however, relatively shorter, their length 

 being scarcely more than the breadth of the bod}^, but they taper to 

 slender tips, as do those of the adults. They are directed back- 

 ward. , 



This specimen is somewhat translucent in alcohol and the thin, 

 marginal bands are very distinct along the sides of the body and in 

 the tail fin. The intestinal pouches, proboscis-sheath, and other in- 

 ternal organs show more or less distinctly, especially posteriorly. 

 In the head there are about 20 sense organs (?) in each lateral 

 cluster. 



Length 35'"'" ; breadth of body 5'"'" ; length of head to base of 

 cirri 4'"'" ; its breadth 4'""' ; length of cirri 5""". 



Perhaps this may be a male and the larger and flatter specimens 

 females. 



A specimen from station 2229 agrees in most respects with the 

 fuUgrown ones described above, except that it is smaller and has 

 short nuchal cirri. In this the body is relatively narrower and less 

 flattened than in the larger examples, but the head, caudal fln, and 

 proboscis are nearly as described and figured. The nuchal cirri are, 

 however, short, tapered, blunt, not much longer than half the 

 breadth of the head, and stand out rather rigidly from the sides 

 of the neck, and nearly at right angles with it. 



This specimen is about 30'""' long ; 7'""' broad ; caudal fin 3-5""" 

 broad ; length of cirri 2'"'". It has been treated with hardening 

 reagents for sections, and is therefore strongly contracted. 



A single specimen was taken at each of the following stations by 

 the steamer Albatross : 



Station 2036, N. lat. 38"^ 52' 40", W. long. 69° 24' 40", 1735 fathoms. 

 Adult. 



Station 2076, N. lat. 41° 13' OO", W. long. 66° 00' 50", 906 fathoms. 

 Young with small cirri. 



Station 2229, N. lat. 37° 38' 40", W. long. 73° 16' 30", 1423 fathoms. 

 Young with small cirri. 



Station 2236, N. lat. 39° 1 1' 00", W. long. 72° 08' 30", 636 fathoms. 

 Adult. 



The specimen from Station 2236 is marked as having been taken 

 in the trawl-wings. Many of the specimens of other groups, thus 

 taken, undoubtedly came from near the bottom, but on the other 

 hand, it is eas}^ for any surface species to be taken in the same nets 

 while the trawl is being loAvered or when it is being taken in. Con-
