I have named this new species in honour of Mr. George Murray, of the British 
Museum, who first drew my attention to it as probably an undescribed form. Its 
nearest ally is T. decurrens, from which it differs in having a short, thick, unbranched 
stem, in the absence of vesicles and the arrangement of the receptacles.

I have not maintained the two varieties havanensis and capensis of Kützing, since 
these appear to me to represent little more than growth-forms; intermediate specimens 
certainly exist. Turbinaria heterophylla, Kütz., also appears to come under this 
species. So far ав one may judge from his excellent figure, it is an irregularly grown 
specimen of T. trialata, nearly related to the form he describes as var. capensis. I have 
examined the specimen of Sir Hans Sloane in the British Museum, and it also falls 
under T. £rialata.
