THE YOYAGE OF H.M.S. CHALLENGER. 
D. The Australian Eegion. 
The types in this area are in many cases peculiar and novel. It and the Indian 
region are distinguished by the ^irominence of the Chloeia group, and the Australian 
specially by the remarkable nature of the Polynoidse, e.g., Lejndonotus cristatus, Polynoe 
mirabilis, Polynoe platycirrata, Scalisetosus ceramensis, Eunoa iphionoides, and Eunoa 
ahyssorum. The latter is also the region of fine examples of the genus Thalenessa, of one 
of the most remarkable discoveries of the Challenger, viz., the branched Syllis, of many 
Eunicidee, from the large Eunice amphroditois downward, of Nicidon, the edible Palolo, 
and the striking Nothria willemoesii with its spinose tube. Comparatively few of the 
species range into the other areas if we except the ubiquitous varieties of Lcetmonice 
producta and one or two others.
