branched. The distance between branchings is from 6.8 cm. to 9 mm. (on distal parts). The 

 polyps are regularly and thickly emplanted on all sides of the branches, there being but a 

 slight indication of median grooves on the anterior and posterior surfaces ; but more thickly 

 on the distal than on the proximal parts of the colony. They are arranged in somevvhat 

 irreoular diagonal rows of about four to each row, reachino- from back to front of the colony. 



The individual calyces are much as in the last species, being club-shaped with their 

 openings turned toward the branch and often pressed against it. A typical calyx measure 

 2.8 mm. in height and 1.3 mm. in greatest diameter. The adcauline wall is about 1.3 mm. 

 long, the calyx being less extensively appressed to the branch than in J. gemmacea. The 

 oral end shows a small central aperture surrounded by eight rather shallow lobes. I am unable 

 to detect any spicules on the tentacles. 



A cross section of the axis near the base shows a distinct difference from other species 

 of the genus examined. There is no central core of homogenious consistency, but the whole 

 axis is made up of interwoven calcareous and horny material, very much as is represented by 

 Kölliker in his figure of the axis of J. gemmacea 1 . 



Spicules. These are much as in the last species, being almost exclusively of two 

 types, the most common being doublé heads or rather club-stars according to the nomenclature 

 adopted in this work. The second form is a typical doublé star. I can find no true spindles 

 except some very minute ones which I suppose to be young spicules. 



Color. The colony is deep crimson throughout. The axis has an olive green cast and 

 the polyps are white. 



This species is closely allied to J. gemmacea. It differs, however, in being more robust 

 in habit, in the size and shape of the calyces, in having no tentacular spicules, and in color. 

 This last character, however, would not, alone, be a sufficiënt one to justify us in regarding 

 it as distinct. It differs from J. racemosa in size of calyces and in the character of the spicules. 



Note on the genus Scirpearea. 



The writer has already (p. 5) given his reasons for regarding this genus untenable. 

 He is further of the opinion that the species heretofore included in Scirpearea could be acom- 

 modated in other genera. Some of these species could be placed in Juncella, and such 

 species as Scirpearea furcata Hickson a could go into the genus Scirpearella as defined by 

 Wright and Studer.
