Descriptio)t. — Body threadlike, greeni.sh yel- 

 low, about 12 mm long by 0.1 mm. Prostomium 

 (Figure 3a) elongate, slightly broader at trun- 

 cate posterior end. Four tapered and subequal 

 antennae, a pair of indistinct eyes, no occipital 

 papilla. Proboscis diffusely papillose. Three 

 well -developed and separate tentacular seg- 

 ments bearing three tentacular cirri and setae 



from second. Formula 1 4- S — r + S — . Ventral

cirrus of second segment iV-,) lamellar but 



tapered distally and longer than V3. Normal 



parapodia (Figure 3b) with a long, blunt, setig- 



erous t9.^, aii eliDigated oral do)'sal ci)'rns 



and a similar but smaller ventral cirrus. About 



eight spinigerous setae per foot; shaft-heads 



(Figure 3c, d) symmetrical and serrated; blades 

 (Figure 3e, f) grading in length. 



Remarks. — As Southern (1914) has remarked, 

 the fact that ti'ntacular cirrus \'2 is longer and 

 more tapeied than \':, makes it difficult to sepa- 

 rate Protomystides from Phyllodoce.

 m (*).

 lantic; Mediterranean; in 10-4,950 m.

Descrijitioii. — Body threadlike, very slender, 

 brownish green, about 15 mm long. Prostomium 

 (Figure 3k) about twice as long as broad, with 

 two pairs of frontal antennae and indistinct 

 brown eyespots. No median antenna. Proboscis 

 with numerous dark brown papillae. Three pairs 

 of tentacular cirri on first and second segments. 

 Both tentacular segments distinct, separate and 

 without setae. Third segment without a dor- 

 sal cirrus but with setae. Tentacular formula: 



1 + 



Srr. First tentacular cirrus cylindri- 



N -^ 



cal and tapered, about 1.5 times segmental 

 breadth, second dorsal cirrus (D2) similar but 

 slightly longer, second ventral cirrus (V2) short, 

 only slightly longer than ventral cirri of subse- 

 quent segments. Normal parapodia (Figure 31) 

 with short, fusiform dorsal cirri, bluntly conical 

 setigerous lobes longer than dorsal cirri but 

 shorter than the very long fusiform ventral cirri. 

 Setae (Figure 3m) four or five in number with 

 bifid or even trifid shaft-heads and short, knife- 

 shaped blades with deeply serrated edges. Pygid- 

 ium with two very long slender anal cirri. 



Remarks. — The blades of the setae fall off 

 easily and this has given rise to Southern's 

 statement, repeated by Fauvel, that simple setae
