including many of these within it. This is an idea which, 

 however, will require considerable discussion hardly appropri- 

 ate to this report, and I must defer a consideration of it to a 

 future occasion. 



Family ANTHEADJB Hertwig, 1888. 



2. CONDYLACTIS PASSIFLORA Duck. & Alic/l., 1 866. 



The Dry Tortugas; i specimen. 



There was no room for doubt as to the identification of this 

 specimen and as the species had already been studied (Mc- 

 Murrich, '89) I did not think it necessary to mutilate the 

 single example of it in the collection. 



Family BOLOCERIM McMurrkk, 1893. 



3. BoLOCERA POLLENS Sp. nOV. 



Station No. 64. American Shoal light bearing N. by W. 

 about 8 miles; no fathoms; 1 specimen. 



The single specimen which I regard as the type of a new 

 species of Bolocera was obtained at the same station as the 

 large specimen of Halcurias. It was badly distorted and 

 rather poorly preserved and I contented myself with cutting 

 out a small portion of the margin for an examination of the 

 sphincter and with removing some of the tentacles for a study 

 of their sphincters. The results of this partial examination 

 were, however, so decisive that I think there can be no doubt 

 but that we have to do with an undescribed species. 



In its general appearance the specimen resembled greatly 

 B. ■pannosa which I described for the Albatross collection 

 (McMurrich, '93), having the same flaccid tentacles and 

 being approximately of the same size. On account of the 

 distortion which the specimen had suffered it was difficult to 

 obtain exact dimensions, but the base measured about 2.8 cm. 

 in diameter and the column about 1.2 cm. in height. The lower 

 portion of the column was smooth or shows only fine longi- 

 tudinal lines due to contraction, but the upper part for a dis-
