V. '07. 10 



Caligorgia flabellum has a wide geographical distribution. 

 It has been taken in the Indian Ocean, off the East Indies 

 and Japan, and in the Eastern Pacific off Central America. 

 It has been recorded from the West Indies, but this record 

 is considered doubtful (Versluys, 1906), as the description 

 given is not full enough for a certain identification of the 

 species.

11 The specimens of this species that were sent to me 

 "consist of three pieces, preserved in spirit, from S.K. 

 "223. Lat., N., 53 7'; Long., W., 14 50'; 410-500 

 " fms. ; 12th May, 1905; and two dried pieces from 

 " Helga CXX. 77 mi. W.N.W. of Achill Head; 382 

 "fins; 24th August, 1901. Assuming that the three 

 " pieces preserved in spirit are parts of one specimen, as 

 "they undoubtedly are, the total length was 780 mm., 

 " but it was incomplete at both ends. The dried speci^ 

 " inens were together 470 mm., but were also incomplete 

 " at both ends. It is noteworthy in the first place that 

 although considerable lengths were obtained there is no 

 " sign that they were branched. It is therefore probable, 

 "although not absolutely certain, perhaps, that one 

 " character of the species is that it is unbranched. The 

 ' ' basal end of the spirit specimen is overgrown by a piece 

 "of coral (Lophohelia v. Amphihelia ramea?), but the 

 " true base is broken off and lost. The axis at the base 

 "is 5*25 mm. in diameter, and diameter of the lower 

 " whorls of zooids is about 10 mm. At the distal end (of 

 " the specimens) the axis has attenuated to a diameter of 

 " 2 mm., and the diameter of the whorl to about 8'25 mm. 

 ' The axis is throughout of a beautiful bronze colour. 

 " There are from 8J-9 whorls in every 30 mm. of length, 

 " the whorls being about 1 mm. apart. The number of 

 " zooids in a whorl varies. At the basal end there are 

 ' ' about 14 zooids in a whorl , at the other end about 9 

 " zooids in a whorl. In the intermediate regions I have 

 " counted 10, 11, and 13 zooids in a whorl. The smallest 

 " number in a whorl is 9. 



" The zooids are 3' 5 mm. in length, if as a measure- 

 " ment of length is taken the distance between the base 

 ' ' of the basal scales and the apex of the aboral opercular 

 " scale. It seems from this measurement that the zooids 

 " are the largest of any known species of the genus, but, 

 "as in other characters , come nearest to the zooids of 

 " S. Studeri, in which the length is 3'25 mm. or less 

 " (Versluys, 1906). As in other species of the genus, 

 ' ' there are three pairs of large abaxial scales on the bod y- 

 " wall of the zooids and eight large opercular scales.
