The coelenterates described in the following pages were collected by- 

 Mr. Owen Bryant at various points along the east coast of Labrador 

 and the south and east coasts of Newfoundland during the summer of 

 1908. The collection consists of twelve species of Craspedotse, one 

 siphonophore, three Scyphomedusse, and three ctenophores. None of 

 the species are new, but inasmuch as the medusa fauna of this region 

 has not previously been studied, the records are of importance from 

 the standpoint of geographical distribution. As might have been 

 expected from our knowledge of other groups of animals, several of 

 the species were previously known only from Greenland and from 

 northern Europe. Such are Sarsia princeps and Ptychogastria polaris. 

 Catablema vesicaria, Bougainvilleo^ superciliaris , Stauropliora lacini- 

 ata, and Aglantha rosea were already known from both sides of the 

 north Atlantic, so that the occurrence of these forms in the region in 

 question, bridging over the gap in their known distribution, was to be 

 expected. The capture of jEginopsis laurentii is of especial interest, 

 since there was already good reason to believe that tliis species would 

 be found to be of general boreal occurrence when the Arctic coasts 

 of North America were more thoroughly explored from the faunistic 

 standpoint. 



Although all the species are well known, two, Catablema vesicaria 

 and jEginopsis laurentii, are of great systematic interest. For- 

 tunately both are represented by such good series that, in the former, 

 I have been able to make a study of the tentacles and of the gonads, 

 and in the latter to verify many points of anatomy important in the 

 general classification of the Narcomedusse. It has been a pleasure 

 to work on specimens of Medusae so excellently preserved as those 

 prepared by Mr. Bryant.
