MISS E. 8. BARTON ON THE GENUS TURBINARIA. 219 
numbers under Turbinaria vulgaris, J. Ag., and under var. decurrens and var. trialata 
in MM. Mazé et Schramm’s ‘Essai de classification des Algues de la Guadeloupe,’ 
рр. 132 & 133. Porto Rico, Herb. Sintenis! Ad ins. Bahama, Palmer! 
This new species, which recalls both 7. decurrens and T. Murrayana, differs from the 
former in the absence of vesicles and in the character of the branching, and from both 
in having а round lamina. From 7. Murrayana it differs further in its branched stem, 
much more slender stem and leaves, and in having a tricostate lamina. From T. trialata, 
which name it has borne іп M. Mazé’s collection of Guadeloupe Algæ, it differs in the 
absence of vesicles and in having toothed wings to the petiole in the mature state. 
Var. WEBERs, mihi; lamina triangulari, petioli angulis edentatis. (Tab. LIV. fig. 4.) 
Hab. Ad ins. Edam et Enkhuizen prope Bataviam, Domina Weber van Bosse legit ! 
This variety shows the tricostate character of the lamina even more plainly than the 
typical form. Though the wings are edentate as a rule, occasionally one tooth may be 
found. 
6. T. DENTATA, n. sp. Caulis ramosus, ramis abbreviatis, vesicularum petiolo subtri- 
quetro angulis obsolete marginatis, vesiculis inflatis cum dentibus validis seriatim 
ornatis, laminam acute dentatam sustinente. (Tab. LIV. fig. 5.) 
Hab. Ad Macassar, Domina Weber van Bosse legit! 
This species approaches Sargassum in appearance more nearly than any of the others ; 
in fact, so far as leaf characters go, it exhibits the appearance of a Sargassum without 
leaves, but with vesicles adorned with a crown of teeth, from which others descend in 
rows to the petiole.

Dawson Turner, Joc. cit. р. 51, says, “ The var. В above described was found by 
Dr. Smith among some loose papers in the Linnean collection, but without any remark, 
or any clue that might lead to discover whence it came.” In the Linnean Herbarium
