120 AUSTRALASIAN ANTARCTIC EXPEDITION. 



Eulalia mcleani (figs. 53-57). 

 Fig. 53. Anterior end (enlarged). 



54. A parapod ( X 20). 



55. A chaeta ( X 500), side view. The appendix is not necessarily curved. 



56. The articulation of appendix ( x 500). 



57. Pharyngeal papillae ( X 70); the two broader ones are seen in a plane different 

 from the rest. A top view of one is shown. 



Pelagobia viguieri (figs. 59, 60). 

 Fig. 58. (There is no drawing corresponding to this number.) 



59. The peristomial cirrus ( x 90) showing the axial chitinous support. 



60. A portion of the cirrus near the base ( x 720), showing the tapering proximal 

 termination of the axial supports, and the thickened cuticle on the posterior 



face of the cirrus. 



PLATE 8. 



Vanadis antarctica (figs. 61-63). 



Fig. 61. A complete chseta (camera, X 30). It was drawn in two parts, a small bubble 

 of air lay about half-way along, which enabled me to join the two sketches 

 accurately together. 



62. Two aspects of the articulation at different foci ( X 360). 



63. Another form of articulation less commonly met with ( x 360). 



Tomopteris carpenteri (figs. 64-66). 



Fig. 64. Head and first segment ( X 10). The cirrus is cut short; its supporting chaeta 

 is shown as projecting a short distance beyond the cut end. 



65. The head of a soft specimen (X 10), showing the epaulette of the left side 

 triangular, as is figured by Quatrefages for the species. 



66. A parapod ( x 10). 



Nereis loxechini (figs. 67-75). 

 Fig. 67. Head of a well-preserved specimen ( x 10). 



68. Head of soft specimen ( X 5). 



69. A parapod of 20th segment, ventral view ( X 10), (a) anterior face, (p) process 

 of the posterior lip. 



70. The 8th parapod in outline ; anterior face ( x 20). 



71. The 34th parapod in outline; posterior face (X 20). 



72. The 80th parapod in outline ; posterior face ( X 20). 



73. One of the stout brown heterogomph falcigers, from the supra-acicular 

 bundle ( x 250). 



74. Heterogomph falciger, from the sub-acicular bundle ( X 250).
