340 Prof. T. Rupert Joues on the 



spot remind us of Cjpriclinal characters (as, indeed, the author 

 himself seems to have thouglit) ; but, though some recent 

 species are deeply sculptured, there are none just like this. 



This Cypridina (?) has iDcen described and figured by 

 Dr. Georg Giirich, of Breslau, in his " Das Palajozoicum im 

 Polonischen Mittelgebirge," in the Verhandl. Russisch- 

 Kaiserl. Mineralog. Gesellschaft zu St.-Petersburg, ser. 2, 

 vol. xxxii. (1896) p. 378, pi. xv. figs. 12 a^ b, c, as Bolbozoe 

 polonica. He found it at Niestachow, Kleczanas, Zalesic, 

 and Brzezinki, in Poland. Specimens vary from 3 to 8 

 millim. in length. (PL XVII. fig. 16.) 



6. In one of the pebbles (consisting of a quartzite doubt- 

 fully of either Silurian or Devonion age) from the Triassic 

 Conglomerate at Budleigh-Salterton in Devonshire, the late 

 Mr. J". W. Salter found a Cypridinal specimen, wliich was 

 subsequently figured and described (but not specially named) 

 in the Geoh Mag. dec. ii. vol. viii. (1881) p. 337, ph ix. 

 figs. 7 a, 7 b. It measured 7 by 4'2 millim. 



Being a mere cast in granular quartzite, with a part of its 

 edge still imbedded, its real outline could not be determined ; 

 but it somewhat resembled certain forms of Cypridina brevi- 

 mentiim and Polycope simplex^ figured in the Monogr. Car- 

 bonif. Entom., Pal. Soc. 1874. (PI. XVII. fig. 15.) 



7. Cyprosina W/iidbornei, J., is a Cypridinid peculiar to 

 the Devonian Limestone at Lummaton, near Torquay, Devon- 

 shire, as far as known at present. It was described and 

 figured in the Geol. Mag. dec. ii. vol. viii. (1881) pp. 338- 

 340, pi. ix. figs. 1-3 and 5 ; see also the Rev. G. F. Whid- 

 borne's Monogr. Devon. Fauna South England, Pal. Soc. 

 part i. (188*J) p. 53, pi. iv. figs. 1-4. Its beak is small, and 

 it has " a short transverse (vertical) sulcus at or near the 

 middle of the ventral region." It occurs of different sizes, 

 the largest measuring about 18 by 12 millim. (PI. XVII. 

 fig. 8.) 



8. In his Monograph on the Devonian Fauna of the South 

 of England, vol. i. part i. (1889), the Rev. G. F. Whidb^rne 

 describes and figures some rather obscure casts of carapace- 

 valves referable in all probability to Cypridina (pp. 4.5, 46, 

 pi. iv. figs. 6, 10, and 18) ; Cypridella (p. 47, pi. iv. fig. 5) ; 

 and a new species, Cypridinella cmca (p. 46, pi. iv. fig. 16). 

 These range from 3*5 to 10 millim. in length, and were all 

 obtained from the old Lunnnaton quarries, near St. -Mary- 

 Church, not far from Torquay.
