366 Mr. H. J. Carter on some West-Indian 



with the usual aculeations) belongs to the genus "'Tuba " as 

 much as the former, I have given this generic name to it, but 

 would place fin's in the 6th group, viz. " Aculeata." The speci- 

 men of T. 2)^icifera is composed of thick ridged fibre, with a 

 circular fringed orifice, about 10 inches high by 5 inches in 

 diameter ; and that of T. Eschriclitii, which is long and 

 trumpet-shaped, is more or less covered with a remarkably 

 irregular form of the outgrowth mentioned, about 164 inches 

 high and 3 1 inches in the longest diameter at its orifice, which 

 is elliptical and not fringed. All three specimens have the 

 same light fawn-colour, and all three the same kind of acerate 

 spicule; that of T. pUcifera is 18 by |-6000ths inch, and 

 that of T. Eschriclitit 18 by |-6000ths inch, in their greatest 

 dimensions respectively, so that it is finest in the thickest 

 fibre, but very scanty in all three. 



Each specimen presents a young one at its base, which is 

 hlind at the free end (that is, without orifice).
