tus ('93, PI. 2, fig. 45), and as has been described for other species 

 of Drepaxophorus. 



Proboscis pore situated ventrally a httle behind end of snout ; 

 mouth opening when body is contracted a short distance behind 

 proboscis pore (PI. 24, fig. 180). 



Length of body 5-10 cm. or more ; width, 4-5 mm. 



Color. — Dorsal surface of body dull reddish or orange, thickh^ 

 covered with very fine brownish dots of such great number and 

 minute size as to give the impression of a general reddish l)ro wn 

 tinge ; deej)er red in the brain region because of the pink color of 

 the brain. Head is somewhat darker in color than rest of body and 

 has on its dorsal surface two indefinite darker brown patches. 



Ventral surface pale flesh color with a tinge of orange ; intestinal 

 lobes commonly impart a tinge of buff. 



Ocelli. — Upwards of 25-35 large black ocelli occupy each side 

 of the head between brain and tip of snout, and are conspicuoiis 

 from the dorsal surface. The ocelli in each cluster appear to be 

 scattered irregularly, and somewhat removed from the lateral mar- 

 gins posteriorly (PI. 17, fig. 106 ; PL 24, figs. 179-181 ; Text-fig. 22). 

 In addition to these ocelli, which are visible from the dorsal surface, 

 a single row of 25-30 large ocelli is situated on each side much 

 nearer the ventral surface, and these are seen distinctly only from 

 below (PI. 24, fig. 180). They lie ventrally near the lateral margins 

 of the snout, and are placed side by side and almost in contact. 

 The single row becomes more irregular and often divided into two 

 posteriorly (PI. 24, figs. 180, 181; Text-fig. 22). The pigment 

 cups of nearly all of these ocelli are directed toward the lateral 

 margins. 



Proboscis. — In the single individual of tliis species which came 

 into my hands alive the proboscis had unfortunately been discharged 

 and lost before the worm was found. 



Proboscis sheath with interspersed longitudinal and circidar mus- 

 cular fibers as usual. It extends to posterior extremity of body, and 

 is provided with diverticula as in related species. These diverticula 

 are of moderate projjortions or rather slender, and extend laterally 

 above the lateral nerves where they expand into thin- walled sac- 

 cules. Khynchocoel vessel passes outside proboscis sheath in the' 

 anterior third of eso])hageal region. A single specimen (probably, 

 but not certainly, belonging to this species) collected by the Alba- 

 tross (definite locality unknown) had 32 proboscidial nerves.
