on the other two surfaces. The tips of the twigs and liraiiohcs are occupied liy 

 two divergent verrucfe with a small interval between them. There is a flat spread- 

 ina; basal attachment. 



The axis is altogether horny, dark brown in colour, hollow in the younger 

 parts. It is marked superficially Ijy a peculiar network with pits in the 

 meshes. 



The polyps are long, 4 nnn. in height, even in a somewhat retracted condition. 

 Ova are abundant, and are arranged in a loose necklace on the mesenteric bands. 

 The non-retractile portions of the polyps are wider than the apices of the verrucoj, 

 and stand out like domes. The spicules on the anthocodife are arranged in a crown 

 and points ; the crown consists of 3-5 (usually 4) rows of slightly curved warty 

 spindles ; each point is triangular in form, and consists of one basal spicule 

 and three pairs of converging spicules, of which the two outer pairs reach 

 to about the same level. At the apex of the triangle there are some minute 

 spicules. 



On the aboral surface of the tentacles there is a baud of longitudinally 

 arranged small spindles, with a few arranged transversely. 



The verrucas are conical in shape with a broad base, and are slightly flattened 

 in the plane of branching. The spicules are arranged in eight bands, each of which 

 consists of two rows of converging spicules. The points of the bands project a 

 little at the top of the verruca. The verrucse vary in length from r9-3 mm., and 

 have a basal diameter of slightly over 2 mm. 



The general coenenchyma is thin, and allows the dark brown axis to shine 

 faintly through the coating of long spindles. 



The spicules of the polyps and verrucae are spindles, straight or slightly curved, 

 covered by warty protuberances. Several of the smaller forms have sharper spine- 

 . like processes. The following measurements were taken of length and breadth in 

 millimetres : 



l-4x0-18; r2x0-22; 07xO-15; 0-4x0-03; 0-16x0-04. 



The spicules of the coenenchyma are shorter and thicker warty spindles. 

 Their dimensions are : 



0-9xO-lG; 0-8x0-12; 0-26xO-06; 0-16x0-05.

Calicogorgia rubrotincta, n. sp. Plate IX. fig. 9. 



This species is represented by two complete reddish colonies, 139 and 96 mm. 

 in height, 88 and 64 mm. in maximum breadth. 



The main stem rises from a flattened basal portion. The axis is dark l)rown, 

 cylindrical, with a diameter of fully 1 mm. It shows no eftervescence when treated 

 with acid, and is formed of layers of dark brown horny fibres with a core of a
