IV. — Some Mediterranean Bryozoa.

[Plate XII.] 



In ray collection there are many specimens which I have 

 intended to describe or revise, but the description of various 

 large collections has prevented, and I am glad now to make 

 a beginning by dealing with five interesting forms from 

 Naples and Oian : — 



Pedicellina hirsuta, Jullien. 

 Lepralia bifurcata, sp. n. 

 Lepralia circumcincta, Neviani. 

 Lepralia oranensis, sp. n. 

 Lagenipora ignota, Norman. 



Pedicellina hirsuta, Jullien. (PI. XII. figs. 1 ? 5.) 



Pedicellina hirsuta, Jullien, ' Bryozoaires, Mission" du Cap Horn,' 

 p. 13, 1888. 



The small specimen from Naples seems to correspond with 

 Jullien's description, and has large recurved spines all over 

 the zoceeium, curved and pointed at the base, and their form 

 suggests that they were movable. The peduncle is large 

 and is also covered witli spines, while the stolon is much 

 narrower than the peduncle. 



In my specimen I am not able to see clearly the base of 

 the peduncle or the adjoining stolon, but believe it is correctly 

 drawn. The contraction near the base has no appearance of 

 being accidental, though more complete material is desirable. 



This specimen was referred to in my description of the 

 Red Sea Bryozoa*. It will be noticed that the zoceeium 

 and peduncle are very exceptionally large (calyx about 

 0*38 mm., peduncle about 0T1 mm.). 



Loc. He Hoste, Orange Bay, 20 met.; Naples. 



Lepralia bifurcata, sp. n. (PI. XII. figs. 2, 3, 4.) 



In specimens from Capri the zoaria have two branches 

 bifurcating at a very wide angle (fig. 2 a). 



ltound the zoarium there are but few zocecia, from four 

 to eight, either surrounding an imaginary axis or slightly 

 flattened. The zocecia are irregularly quadrate, granular,
