greAV in an obUfjiie or creeping jiosition, the branches heing nearly 

 all secund and crooked, and the branchlets much shorter and erect. 



The spicula include several forms and sizes of double-spindles. 

 The larger double-s])indles are slender and acute, with a wide median 

 space ; each end with three or four whorls of well sc]>arated, nearly 

 simple warts; the whorl next to the median space is largest, the 

 others diminishing regiilarly to the ends. Stoiiter double-spindles 

 much shorter and thicker, blunt at the ends, of several sizes ; lai'gest 

 ones Avith a wide median space bordered by whorls of large rough 

 warts ; beyond these, and close to the warty end, there is a much 

 smaller whorl, with small crowded warts ; the shortest ones have the 

 two whorls on each half and the terminal cluster of warts crowded 

 together into a sort of rounded triangular head ; some very small 

 ones have the second whorl well separated from the median and close 

 to the end. Other small spicula, approaching the form of double- 

 heads, have a very narrow median space bordered by close whorls of 

 very small, crowded, rough warts, which are confused with the ter- 

 minal cluster ; in an end view the whorls show four or five close warts. 

 Cross-shaped s]>icula occasionally occur, which have four nearly equal, 

 club-shaped arms, covered with rough warts. The longer double- 

 spindles measure •102""" by -036"'"', '096 by '042, '096 by -036, -090 by

The spicula, though much smaller, resemble most those of L. rigi- 

 da and X. cuspidata^ from which it differs in the length and slender- 

 ness of the branchlets, etc. When young it branches much like L. 

 alba. 



F. — Imperfectly flabelliform. Brandies free, rather stout, rigid when dry. Ter- 

 minal branchlets elongated. Cells in lateral bands, flat or slightly prominent.
