A. W. WATERS—REPORT ON THE BRYOZOA, 145 
This also is seen in typical S. wnicornis, though not usually as marked. 
This is what Pallas described as Eschara spongites *. 
Although many large pieces have been examined, no ovicells have been 
found. There are about 18 tentacles. The surface pores of this variety are 
usually larger than those of S. wnicornis typica. 
Pallas described this species, and referred to the diagonal arrangement of 
the polypides, and (p. 45) says “& osculo, ad alterum plerumque latus 
declinato.” He refers to figures by Imperato, Besler, and Gaultier ; but the 
figures of Imperato are very unsatisfactory, merely representing some 
incrusting growth on the root of a seaweed, but there is nothing to indicate 
the genus or species, or even the order. However, I have frequently seen 
Schizoporella sanguinea in the Mediterranean incrusting this seaweed just as 
ficured. Gaultier’s figure to which Pallas refers occurs on the back of a 
titlepage. The titlepage of each part has the figure of a coral on the back, 
and the tail-pieces are also corals, each with a short description. (Gaultier’s 
figure is very characteristic of what I described as S. errata, and the inscription 
underneath is “ Porus anguinus crustaceus tubulatus capsulis minimis ex 
Museo N. Gaultieri, No. 55.” This was known as ‘ Lapis Spongize,’ and was 
used medicinally. Doubtless the medicinal efficacy did not depend upon a 
strict adherence to one species or variety. 
This is not the S. spongites of Smitt, Hincks, and Thornely, showing how 
dangerous it is to try and identify species insufficiently described by older 
authors. 
I have seen this variety in Lamarck’s collection marked spongites, but there 
were some other things also with the same name. 
Loc. Mediterranean, Naples, Corsica. From s.s. ‘Thyra’ from the Medi
