grew in an obliqne or creeping position, the branches being nearly 

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



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

 The larger double-spindles are slender and acute, with a wide median 

 space ; each end with three or four whorls of well separated, nearly 

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

 others diminishing regularly to the ends. Stouter double-spindles 

 much shorter and thicker, blunt at the ends, of several sizes ; largest 

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

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

 smaller whoi-1, 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, crow^ded, rough warts, which are confused with the ter- 

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

 Cross-shaped spicula occasionally occur, which have four nearly equal, 

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

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

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

 da and L. mispidata, from which it diiFers in the length and slender- 

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

 alba. 



Y. — Imperfectly flabelliform. Branches free, rather stout, rigid when dry. Ter- 

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