Loc. Red Sea. Wasin, 20 fath. (520), collected by Crossland, 



Smittina sp. 



There is a small piece of Smittina encrusting Adeonella platcdea, 

 which has the peristome very much raised, especially at the distal 

 part, and there is apparently a triangular avicularium in the lip. 

 There are perforations round the ])order of the zocecium, and the 

 small ovicell is not much raised and is at the base of the peristome, 

 and at each side of the ovicell close to the edge there is a small 

 clear spot. There are two openings in the ovicell of S. ocidata 

 MacG., and sometimes others; and I find in a specimen sent me 

 by Jullien as iS. longirostris J., there is a similar spot at the side 

 of an ovicell. Jullien's species has large frontal avicularia, 

 whereas none are found on the small fragment. The lyrula is at 

 first very narrow but spreads out widely on each side. I hesitate 

 to give it a name until better specimens are found. 



Loc. Ras Osowamembe, Zanzibar Channel, 10 fath. (504).

Miss Philipps described and figured the ovicell as with opaque 

 granulations, globular and depressed ; and Miss Thornely, not 

 aware that the ovicell had been seen, described it as with large 

 circular pitted areas punctured in their centres. In a specimen 

 in my collection, from " Singapore or Philippines," the ovicell has 

 the pores fairly similar to, and about the same size as, the poi'es 

 of the zooecia. MacGillivray had previously described the ovicell 

 of his L. feegensis, but as the avicularium, which is directed down- 

 wards is in quite a different position, I doubt whether it is the 

 feegensis of Busk. He described the ovicell as large, rounded, 

 prominent, and marked similarly to the zooecia. In the specimens 

 from Zanzibar (501) thei'e are no ovicells, glands, ovaria, or 

 testes but in those from (511) there are many ovicells which are 

 perforated, though when the ovicell contains an ovum or embryo 

 these perforations look dark and opaque. 



There are about 2(5 tentacles, and the operculum closes the 

 ovicell. There are several ovarian cells in an ovarium.
