On Prof. G. Sequenza’s List of Tertiary Polyzoa. 265 
XXVITI.—Note on Professor G. Sequenza’s List of Tertiary 
Polyzoa from Reggio (Calabria) *. By the Rev. THomas 
Hincks, B.A., F.R.S. 
WE are indebted to Professor G. Seguenza for a very able 
report on the Tertiary formations of Reggio, which includes 
a list of the Polyzoa found in the various beds of the district. 
Many species supposed to be new are described and illustrated 
by excellent figures. Amongst these are a number of forms 
that seem to me to have been raised to specific rank on very 
insufficient grounds ; and as the maintenance of false species 
is clearly an injury to science, I venture to submit this portion 
of Prof. Seguenza’s work to some critical revision. 
Lepralia elegantissima, Seguenza (p. 83, pl. vii. fig. 11). 
This is undoubtedly referable to Cribrilina radiata, Moll, 
form ¢nnominata, Couch. The species is a variable one; but 
Seguenza’s Miocene form does not depart in any essential point 
from the type. It agrees very closely with the Pliocene Lepralia 
innominata of Manzoni (Sitz. d. K. Akad. d. Wiss. in Wien, lix. 
Bd. i. Abth. Jiin.-Heft, 1869, pl. ii. fig. 13), The characters 
relied upon by Seguenza as distinctive (absence of avicularia, 
free development of ocecia, &c.) are quite insignificant. He 
remarks that L. e/egantissima is most nearly allied to L. radi- 
ata and L. figularis, and more especially to the Floridan form 
of the latter . This form, however, is not the true jigularis, 
but merely a variety of radiata to which I have no doubt 
elegantissima also must be referred. 
Lepralia radiato-foveolata, Seguenza (p. 129, pl. xii. fig. 20). 
Identical with Microporella violacea, Johnston. There is 
perfect agreement with the latter species in all the essential 
characters, and even the superficial sculpture has a very exact 
parallel in the Crag form of JZ. violacea, which I have de- 
scribed in my ‘ History of British Marine Polyzoa’ (p. 218, 
pl. xxx. fig. 4) f. 
Cumulipora porosa, Seguenza (p. 130, pl. xu. fig. 21). 
Not distinguishable from the well-known Smittia trispinosa,
