It was observed that the exterior of the tubes, in fractured specimens, was invariably 
delicately wrinkled in the peripheral regions ; but the fortunate oeenri’ence of a 
weathered and aemi-decom])osed specimen in Mr. T)e Vis’ Collection, revealed the 
presence of very fine and regular moniliform constrictions of the genus. These do not 
seem to bo visible in any other state, and are certainly not to be seen in thin sections, 
so far as our united observation has gone. 
The corallum is usually from five to six millimetres wide, two tubes in the 
peripheral region occupying the space of one millimetre. The bifurcation is very 
regular, the branches always terminating in a lobato, or semi-plumose expansion. They 
possess this character to a much larger extent than any other Stenoporce, and the 
individual branches are shorter. Herein lies a marked difference to Dana’s illustration 
of his Stenopora {Clicelcles) gracilis* !a\di an equally strong resemblance to his figure 
of Stenopora ovata, Lonsdale. f 
_ The axial portion of the corallum is as correspondingly narrow, as the peripheral 
IS wide, and the angle of deflection between the two is a most marked one, quite a right 
ungle, the peripheral portion of the tubes being perfectly horizontal. 
When compared with Stenopora Jnchii the present species, S. gimpiensis, appears 
more robust, with stronger branches, and in place of the regular annulations, the 
exterior of the tubes is but faintly wrinkled. The stability of character displayed by 
this coral marks it as a good species, which T propose to call Stenopora giinpiensis, from 
its frequent occurrence in the rocks of that Goldfield. The figures (PI. 6, figs. 14 and 
are not eminently satisfactory, and it will be refigured in the Supplement to this 
Work.
