Owing to lack of full and accurate descriptions, and espe- 

 cially figures, of the remaining genera of the family, I am 

 unable to state how many more can be consistently char- 

 acterized as Polynoe or Harmothoe in the wide sense. 



Polynoe squamata (Z.) And. et M.-Edw. 

 Plate VII, Fig. 30. 



The occurrence of this North Atlantic and Arctic species 

 on this coast was quite unexpected, inasmuch as it does not 

 appear to be so widely distributed, or to occur in such high 

 latitudes as the ubiquitous Harmothoe imbricata. I believe 

 it has not hitherto been reported from the Pacific, or indeed 

 from the western portions of the Arctic. 1 



It is by no means a common species on the California 

 coast, and, as far as my observation goes, does not occur 

 within the littoral zone. The nine specimens at my com- 

 mand were all obtained in Monterey Bay; some dredged in 

 twelve fathoms on stony ground, others brought up on 

 stones by a Chinese fisherman from a depth of 90 to 100 

 fathoms. 



I find nothing in the external anatomy of these specimens 

 that would justify specific distinction from P. squamata. 

 They are all much smaller than the general run of Atlantic 

 specimens (the largest measure only 16 mm. in length), but 

 otherwise it is difficult to find even varietal difference be- 

 tween them and specimens of typical P. squamata from the 

 New England coast. 



1 This species is entered in Dr. Woodworth's catalogue of Prof. Alex. Agassiz's collec- 

 tion from this coast, as having been obtained from the Gulf of Georgia. Nothing has 

 been published concerning it.
