Juncella elongata, Pallas. Plate I. fig. 10 ; Plate IX. fig. 17. 



This species is represented by two branched pieces, 220 and 160 mm. in 

 length. In both the base is present, and consists of a flattened portion, slightly 

 conical in one specimen, spreading over the surface of a calcareous con- 

 glomerate. 



The axis is calcareous, rigid, and brittle ; it is slightly oval in section, but in 

 the younger portions it becomes quite cylindrical and tapers till it is thread-like. 

 It shows a very white core surrounded by a brownish cortex. It has a maximum 

 diameter at the base of 3 '3 mm. 



The verrucse are low and truncate, and arranged in four rows in the older 

 portions. In the younger parts they appear to be arranged in two rows on the 

 opposite lateral faces. They have a height of about 0'5 mm. and a diameter of 

 1"5 mm. at the base. 



The coenenchyma is thick, brick red in colour, and contains three types of 

 spicules, of which the following measurements were taken of length and breadth 

 in millimetres : 



1. Spiny spindles, 0-13x0-025 ; 0'12xO-03; O'lxO'03. 



2. Double clubs, 0-09x0-05; 0'08x0'045; 0'OG5xO'04 ; O'OGxO'04. 



3. Double stars, 0-08x0-04; 0'07x0'04; 0'07x0'35. 



There is a trace of a bare space and a ridge-like mark ; otherwise the 

 specimens agree well with Juncella elongata. 



Locality : Bay of Bengal ; 88 fathoms. 



Previously recorded from Atlantic (Pallas) ; West Indies (Ellis and Solander) ; 

 variety from N.E. coast of Australia (Ridley) ; var. capensis, Algoa Bay (Hickson). 



Juncella miniacea, n. sp. Plate V. figs. 7 and 12. 



A fragment of a beautiful vermilion red colony, 43 mm. in height. 



The stem, which lacks its basal portion, bears two large cirriped galls, one 

 near the lower end and the other almost at the middle point. It gives off three 

 alternating branches all in one plane. On the stem and branches the polyps are 

 closely disposed and arise from all sides, even on the surface of the galls. The 

 axis is very calcareous, straw-coloured, flexible, cylindrical, with a .smooth surface 

 and a diameter of 0"5 mm. near the lower end. 



The verrucae occur in a crowded irregular spiral, the fourth being often 

 vertically above the first. They are large and prominent, ovoid in shape, and 

 usually curved towards the axis. The polyps are wholly retracted, and in this 

 condition the apex of the verrucse shows a small median aperture marked by an 

 eight-rayed star. They are T25 mm. in height, and have a basal diameter of 



1 mm. and an apical diameter of 0"75 mm.
