NO. 1 TAYLOR: PACIFIC MARINE ALGAE 149 



Bonnemaisoniaceae 



Plants of moderate size, slenderly branched, with an evident axis and 

 extensive branch systems; the minor branches commonly beset vi^ith nu- 

 merous slender branchlets of limited growth forming brushlike tufts ; spo- 

 rangia absent ; spermatangia covering enlarged branchlets ; carpogenic 

 branches three celled, formed in the cortex of the fertile branch, a peri- 

 carp formed partly from the lowest ceil of the carpogenic branch.

 Asparagopsis Sanfordiana Harvey

Mexico: Is. Revilla Gigedo, from the shore pools at Sulphur Bay, 

 I. Clarion, no. 39-44, 17 Mar. 1939. Ecuador: Manabi, dredged in 

 4-15 meters' depth off I. Salango, Schmitt no. 398B-35, 18 Jan. 1935. 



Asparagopsis Sanfordiana f. amplissima Setchell & Gardner 



Setchell & Gardner 1824a, p. 760, pi. 22, fig. 3, pi. 41. 



The specimens from Punta Cristofer reached a maximum length of 

 33 cm, although broken, and so exceeded the length specified for this form 

 in the above description very considerably. However, one should note that 

 the typical form of the species has been recorded in excess of 25 cm tall. 

 The primary lateral branches are longer than those described by Setchell 

 and Gardner, reaching 8 cm, though theirs in turn were longer than the 

 typical form of the species, which reach about 2.5 cm. The specimens from 

 the Is. Revilla Gigedo and from I. Santa Maria are rather fragmentary, 

 but probably also belong to this form.
