One example, found stranded on the beach. The specimen is 

 not in a good condition, and is doubtfully referred to this species. 



CLASS ACTINOZOA. 



Subclass ZOANTHARIA. 



Order AN TIP ATH ARIA. 



FAMILY ANTIPATHID.E. 



ANTIPATHELLA BROOKII, sp. nov. 



The corallum is erect, pinnate and branched in a single plain ; 

 it is 8 cm. in height and 6 -5 cm. broad ; the stem (?) at the base 

 is 1 mm. in diameter. 



The specimen consists of two main fronds, having the shorter 

 branches fused here and there at the base but free at the summits. 

 Each frond gives off a series of alternate rarely opposite pin- 

 nules. The primaries arise almost at right angles, and are slightly 

 curved upwards at a short distance from their origin. The second- 

 aries also are at right angles to their support ; they are generally 

 straight, simple, or with numerous short branchlets, occasionally 

 a few are elongate and slightly curved. 



The primary pinnules are from 2 to 3 cm. in length, and pretty 

 regularly 4*3 mm. apart ; the secondaries are from 5 to 15 mm. 

 in length and 3 mm. apart ; the tertiary pinnules vary from 1 to 

 7 mm. in length. 



The polyps on the pinnules are situated on the anterior surface, 

 forming a single longitudinal series ; there are six to 1 cm. ; they 

 are about I'l mm. in length, and are separated from each other 

 by short intervals varying from 0'2 to 0-4 mm. 



The polyps do not commence at the bases of the branchlets ; 

 there is generally a nude space from 0-4 to 0-6 mm. in length 

 at their point of origin from the stem. The latter also usually 

 has a similar polyp-less space above and below the base of a 

 branchlet. On the stouter portions of the corallum a few of the 

 polyps are radiate or subradiate, elsewhere they are elongate. 

 There are two distal and two proximal tentacles situated in a line 

 with the pinnule, and two placed transversely one on each side 

 of the mouth which are generally smaller and inserted on the 

 sides of the pinnule, not on the anterior surface as is the case with 

 the other two pairs. The tentacles are about 0-25 mm. in length. 

 The oral prominence is slightly elongate transversely, it is O'l mm. 

 in height, 0-5 mm. in its longer and 0-35 mm. in its shorter dia- 

 meter. The mouth is a narrow, elongate, slit-like opening, with
