of the specimens of Kumlien belong to the narrow form, and grew at 

 low-water mark. A specimen from forty fathoms is eight inches long, 

 with broad ultimate divisions. 



Halosaccion ramentaceum, J. G. Ag. 

 But few specimens of this common species were collected, and none 

 of them were at all equal to New England specimens in luxuriance 

 of growth. The specimens of Phyllophora membranifolia mentioned as 

 collected by the Howgate Expedition in the Bulletin of the National 

 Museum, No. 15, are in reality narrow forms of H. ramentaceum. 



PnYLLOPHORA INTEURUPTA, J. G. Ag. 



Fine typical specimens of this species were collected at Point 

 Barrow, but only a single specimen appears in the collection from 

 Ungava Bay. 



Kallymenia Pennyi, Harv. ? 



Ungava Bay (Turner, no. 451 and 4873). Two small portions 

 of a Kallymenia were among the mounted si^ecimens, and there were 

 besides several much larger specimens in the rough-dried material, 

 some of which bore cystocarpic fruit, so that there can be no doubt 

 of the generic detei'mination. None of the specimens showed any 

 trace of a stipe or a point of attachment. The more perfect were 

 nearly a foot in diameter, and deeply and irregularly lobed at the cir- 

 cumference, the general outline being somewhat oval. Some of the 

 fronds were perforated with a few holes, the largest of which were 

 half an inch in diameter, but the majority were much smaller. The 

 holes were evidently not the result of erosion or decay, but similar to 

 the holes which normally appear in the fronds of certain Alga3. The 

 color was the same as in British specimens of K. reniformis, but the 

 thickness of the fronds was somewhat greater than in that species, 

 although it should be added that different authentic specimens of K. 

 reniformis vary considerably in thickness. 



Tlie present form certainly is not K. ornata, P. & R., which has a 

 different color, substance, and habit, and, in spite of the existence of 

 perforations in the frond, I think it must be referred either to K. reni- 

 formis or K. Pennyi. With regard to the last-named species, the 

 descriptions are hardly sufficient to enable one to distinguish it with 

 accuracy, and the question arises whether it may not, after all, be a 

 luxuriant Northern form of K. reniformis. K. Pennyi was originally 

 found in the Gulf of Cumbarland, and in all probability the speci- 

 mens from Ungava Bay may be referred to the same species, whether
