ON FOSSIL POLYZOA. 135 



In his ' Bryozoa of the Bay of Naples ' (p. 273, op. cit. Ap. 1879), Mr. 

 Waters associates with A. repent!, Wood, the Diastopora echinata, Rss., and 

 D. repi. ns, Smitt, and describes, but does not figure, a variety of ^4. repens, 

 Wood, as A. repens, var. vitriensis (habitat on Terebratula vitrea). Mr. 

 Hincks, however ('Brit. Mar. Polyzoa,' p. 427), gives the following 

 synonymy : Stomatopora major, Johnston = Tubulipora repens, S. V. Wood 

 = Alecto repens, Busk, ' Crag Polyzoa,' pi. 112, fig. 8 (not fig. 5). 



6. Stomatopora granulata, M.-Edw., Hincks, p. 425, pi. lvii. figs. 1, 2; 



Busk, ' Brit. Mus. Cat. III.' p. 23, pi. xxxii. fig. 1 = 8. granulata, 

 D'Orb ; S- incrassata, D'Orb., 'Pal. Fr.' = ? Alecto parasita, 

 Heller, ' Bry. Adr.' p. 40, pi. iii. fig. 10 =? Alecto parasita, 

 Manzoni, ' Castrocaro,' p. 41, pi. vii. fig. 69 = ? Stomatopora. 

 minima, Roemer, 'Bry.' woodcut, p. 22, pi. iii. fig. 2. 

 Range. — Hincks says, ' Gres vert inferieur, France ; Norddeut. Tert. 



Oligocan' (Roemer, 8. minima) ; Castrocaro (Manzoni). Living: Adriatic 



and Brit. Seas. 



7. Stomatopora rugulosa, Rss. ; Axdopora ibid. Rss. ' Foss. Pol. dos 



Wiener Tert.' Marine Limest. 



8. Stojiatopora divaricata, Rss. ; Aulopora, ibid. Rss. ' Foss. Pol. de3 



Wiener Tert.' Marine Limest. 



9. Stomatopora regularis, Gabb & Horn ; Alecto ibid., G. & H. ' Mon. 



Foss. Pol.' Cretaceous, New Jersey. 

 I give the above on the authority of the authors rather than suppress 

 the names. 



10. Stomatopora major, Johnst. ; Hincks, ' Brit. M. Pol.' p. 427, 



pi. lviii. and pi. Ixi. fig. 1 = ? Tubulipora repens, S. Wood; 

 Alecto ibid., Busk, ' Crag Poly.' p. 112, pi. xx. fig. 8 (not 5) = 

 Tubulipora fimbriata, ? Michelin (Busk, loc. cit. p. U2) = Idmonea 

 ramosa, D'Orb. p. 632, figs. 1, 2 (Busk, loc. cit. p. 112) ; Waters, 

 ' Bry. Bay Naples,' loc. cit. p. 273, as Alecto repens, Wood. Syn. 

 Waters, iJiastopora echinata, Rss. ' Foss. Polyp, des W. T.' p. 52, 

 pi. vii. figs. 14, 15 ; IJiastopora repens, Smitt, ' Krit. Fort.' p. 395, 

 1866. 

 Range. — Miocene, Eisenstadt (Rss.) ; Pliocene, Crag, Castrocaro 



(Manzoni — as S. major, Hks.), Coralline and Red Crag. Living: Several 



localities, Brifc. Seas ; Naples. 



11. Stomatopora dilataxs, Johnst.; Hincks, 'B. M. Poly.' p. 420, 



pi. lvii. figs. 3, 3a = Alecto ibid., ' Crag Polyz.' p. 112 (A. 

 ililatans, W. Thomson, pi. xx. figs. 6, 7) = ? Alecto repens, 

 Manzoni, 'Castrocaro,' p. vi. fig. 72 (Hincks) = (Syn. Busk) 

 Diastopora echinata, Rss. ; Idmonea divaricata ?, T. depressa (?), 

 I. cenomana (?), I. clegons (?), D'Orb. Compare the synonymy 

 of 8. major and 8. dilatans. Hincks gives ? Proboscina ramosa 

 = Idmonea cenomana — as syn. of Stomatopora expansa, Hincks, 

 ' Brit. M. Poly.' p. 432, pi. lxii. fig. 1. 

 Range. — English Crag (Busk) ; Miocene and Pliocene (remains for 

 closer comparison). Living, Brit. Seas. 



12. Stomatopora incrassata, Smitt (sub-genus Proboscina, Smitt), 



Hincks. ' Brit. M. Poly.' p. 436, pi. lix. figs. 2, 3 = Filisparsa 

 ibid., D'Orb. 'Pal. Fr.' p. 817. For other synonymy see Busk, 

 ' B. M. Cat.' pi. iii. p. 24. In a fossil state it is almost impossible 

 to correlate, with any degree of positive exactness, these and 

 recent forms. The relationship which these synonyms are
