214 GRIFFIN. 



13. Amphiporus drepanophoroides n. sp. 



Color red above, white below. Length probably not over 

 4—5 cms. Form short and stout. Eyes numerous in rows 

 along antero-lateral margin of head. 



Internal Anatomy, Proboscis-pore terminal. Cephalic 

 gland prominent. Integumentary glands also prominent in 

 head, all situated ventrally and ventro-laterally. Further back 

 they commence to thin out (at first in the mid-ventral line) and 

 disappear completely a short distance behind brain. Mouth 

 opens into rhynchodeum. Cephalic organs large, anterior por- 

 tion opposite ventral commissure, closely pressed against brain, 

 further back they become pushed in between dorsal and ventral 

 ganglia and extend back of dorsal ganglia. Their canals open 

 laterally in front of ventral commissure. Differs from all the 

 preceding Amphiporids in the smallness of the rhynchocoel, 

 and in having the latter enclosed in a thick muscular sheath in 

 which longitudinal and circular muscles are interwoven. No 

 forwardly extending intestinal caeca. Circular muscle-layer 

 quite thick.

14. Lineus striatus n. sp. 



Owing to loss of all color notes and drawings by shipwreck, 

 no detailed description can be here given of its appearance dur- 

 ing life. 



Color brownish red on dorsum, sharply marked off laterally 

 from the much lighter ventral portion. Dorsum marked by 

 numerous creamy white transverse bands which cease at the de- 

 markation-line between the dorsal and ventral coloring. Tip of 

 head brilliant red. Length probably not over 4 cms. 



This form seems from the above quite similar to Micnwa fascio- 

 lata, yet it is at most but one-half the size of the latter, much 

 flatter, the pattern much sharper and constant, and in all speci- 

 mens obtained no cirrus was present. For these reasons it must 

 at present be referred to Lineus.
