of course specifically distinct from our coral. I have been un- 

 able to secure specimens of Worthen's species for comparison, 

 and in his description he does not mention the generic charac- 

 ters nor does he figure the interior of the specimen so as to show 

 whether or not it had any tabulae. If it turns out to be a Lo- 

 phophyllum , his name will, of course, have priority.

Meek's description, in part: " Corallum simple, attaining a 

 rather large size, elongate conical, and often geniculated or bent 

 when two or three inches in length, but becoming nearly 

 straight, subcylindrical and considerably elongated in the larger 

 half of adult individuals. Epitheca thin, with small encircling 

 wrinkles and strong undulations of growth, showing no traces 

 of septal cosko when unabraded, but, where even slightly worn, 

 exposing the regularly disposed septa and thin intervening dis- 

 sepiments distinctly. Galice circular or slightly oval, compara- 

 tively shallow, with thin margins, from which it slopes rather 

 steeply inward for some distance and then descends very 

 abruptly into a deeper, narrow, central depression ; provided 

 at the outride of the general curve of the corallum with a mod- 

 erately distinct septal fossula, formed by the shortening of one 

 of the primary septa, and the bending down of the tabulae at 

 tli at point. Principal septa from 30 to 48, extending from 

 about one-half to two-thirds the distance from the exterior 

 toward the center, stout and usually straight inside of the 

 outer vesicular zone, but becoming distinctly more attenuated 



- seen in transverse sections) and somewhat curved or a little 

 tlexuous in crossing the vesicular area, where they alternate 

 with an equal number of very short, thin ones ; tabuhr very 

 wide, or occupying about two-thirds the entire breadth, as seen
