308 PERCY SLADEN TRUST EXPEDITION. 
they recede from this side they gradually get smaller, and on the surface opposite the 
larger spines they are entirely absent throughout the length of the axis. Blunt in shape, 
they turn sharply upwards and are much papillated. 
The skeletal canal occupies } of the total diameter of the axis. 
A straight axis 46 cm. long with base, but lacking the top, occurred with the ahove 
specimen. This specimen measures 6 mm. in width at the base and 2°5 at the broken end. 
The spines are arranged in numerous irregular rows and have the same shape as the above 
specimen. In the place of the blank line, however, there is a mass of small spines like 
secondary spines. It is possible that these two parts belong to the same colony.

Genus CIRRIPATHES, Blainv. sensu Brook. 
9. Cirripathes anguina, Dana. (Plate 41. fig. 3.) 
Only two specimens of this genus were obtained, both belonging to this species. The 
larger colony measured 20 em. in height, the smaller being half that size. 
The polyps are arranged in irregular spirals around the corallum. The skeletal canal 
is large. The spines are blunt cones which point somewhat upwards, arranged in 12-14 
irregular sinistrorse spirals. They are a little larger on the outside of the spiral.

Genus SCHIZOPATHES, Brook. 
10. Schizopathes affinis, Brook. (Plate 41. figs. 1, 2.) 
The colony consists of a single straight axis 36 em. high giving off alternating branches 
to the number of 72 on each side. Theseare 19cm. long at the bottom of the series and 
evadually shorten to a length of 3 cm. as the apex of the colony is approached. A regular 
interval of half a centimetre separates the branches except at the tip, where they are
