The type-specimen of S. crinita, LonscL, now in the British Museiim, is a large mass about 4^ inches in length and composed of long basaltiform corallites, which diverge from one another bj the interpolation of new tubes with a very gentle outward inclination. The average diameter of the corallites is about half a millim., and they are polygonal in shape and in close contact throughout. The growth of the corallum was periodic, and the entire mass (as shown in Lonsdale's excellent figure) is stratified, the polygonal coral- lites showing a slight transverse wrinkling as they approach the upper surface of each successive stratum. It seems almost certain, however, that the type-specimen is only tlie central portion of a large corallum of which none of the outer portion is preserved ; and there is therefore no reason to doubt that the corallites in the peripheral region of the corallum would exhibit the characteristic annulations of the genus.
