Harmothoe abyssorum (figs. 30-35). 
Fig. 30. View of the head ( X 10). 
31. Front view of the prostomium, showing the tips of the “ peaks ” and the 
relative position of insertion of the median and lateral tentacles. 
32. A cirriferous parapod (camera, X 10). 
33. A tubercle of an elytron, side and top views (enlarged). 
34. A dorsal chseta ( X 90). 
35. A ventral chseta ( X 90). 
Eulagisca corrientis (figs. 36-38). 
Fig. 36. The head dorsal view ( X 5). The tentacles are broken off, the palps are 
represented as having been cut away to a greater or less amount, and the sub- 
tentacular frontal cone (/.c.) is seen below and projecting beyond the tenta- 
culophore. The peristomial parapod is produced into a fine point (l) between 
the dorsal and ventral cirri. 
37. View of the head from in front ( X 5), showing the position of the frontal cone. 
The three tentacles are seen to lie in the same plane. The peristomium is 
foreshortened, and only the apex of the lobe (l) and insertion of the two cirri 
are indicated; (l) elytrophore of second segment. 
38. The second elytron ( X 10). 
Plate 7. 
Eulagisca corrientis (figs. 39-42). 
Fig. 39. The eleventh parapod, anterior face (x 2|). 
40. One of the upper dorsal chsetse ( X 45). 
41. A ventral chseta from the middle of the bundle ( X 45). 
42. A ventral chseta from the lower part of the bundle (X 45). 
Hermaaion rouchi (figs. 43-47.) 
Fig. 43. One of the most dorsal chsetse from a large individual ( x 45). 
44. The apex of one of the smaller dorsal chsetse from the upper part of a bundle, 
from one of the smaller individuals ( X 250). 
45. The apex of one of the largest dorsal chsetse, much worn ( X 250). 
46. One of the uppermost chsetse of a ventral bundle of a large individual ( X 45). 
47. One of the lowermost ventral chsetse of a large individual ( X 45). 
Eulalia hunteri (figs. 48-52). 
Fig. 48. Anterior end of the worm ( X 9). 
49. The head (x 27). Only the appendages of the right side are completed. 
50. A parapod, anterior face (camera, X 20). 
51. A chseta ( X 250) : the appendix is not necessarily curved. The outline is too 
heavily drawn; it is in the object extremely fine. Note the peculiar articulation. 
52. A group of pharyngeal papillse (x 35); three are shown from above.
