St/mphf/ltia labi/rinthica, sp. n. 



Corallum large, massive, rudely inverted, conical, with 

 plane or slightly convex surface. Lateral and under surface 

 with longitudinal striae, apparently not spinous, tiiis surface 

 usually covered by attached organisms quite close to the up[)er 

 margin. Upper surface of sinuous labyrinthine calicinal 

 series, the walls com])letely amalgamated, with no traces of 

 grooves between. Width of calices 13 to 15 millim., depth 

 8 millim. There are usually two septa connecting the cali- 

 cinal centres, sometimes traces of a third, sometimes only one 

 is present. There are about fourteen large and small septa 

 in the distance of 10 millim., the large septa with prominent 

 spinous teeth, the smaller serrate or unequally jagged. 



There is but a single specimen, which is 7*5 centim. in 

 height and 25 centim. across the surface. 



This species is nearest allied to S. agan'cia, E. & II., and 

 to S. acuta, Quelch, but from these it is readily distinguished 

 by the narrowness and less dej)th of the calicinal valleys. 

 It has been compared with S. neijlecta, a MS. species in the 

 British Museum, but its mode of growth and other features 

 readily distinguish it from the type of this form.
