POLYZOA. 109 



Catenicella elegans, Busk (1). 

 Locality : Gulf of Manaar (attached to floating oyster cages). 



Family: CELLULARIID.F,. 

 Scrnpocellaria cervicornis. Busk (2).

Scnvpocellaria diadema, Busk (2).

 Station LXIIL, west of Periya Paar, 17 to 55 fathoms (large quantities). 



Scrupocellaria scrupea, Busk (2).

Caberea retiformis (Pourtal^s). 



The peculiar, unequal development of the fornix, mentioned by Miss Phillips (25), 

 is a characteristic of these Ceylon specimens. The upper half is developed into a 

 long, sharp process, while the lower is scarcely produced below the stem by which it 

 is attached to the zooecium. Avicularia are present both along the median line and 

 on the ocecia. 



Locality : Off Galle in deep water. 



Family : BICELLAPJID/E. 



Diploecium simplex, Ktrkpatrick (20). 

 Localities : North of Cheval Paar, 7 to 10 fathoms ; oft* Manaar; and off Galle. 



Bugula neritina, Linn. 



There is one specimen in the present collection which differs from the others, being 

 lighter in colour, less rigid in growth, and with avicularia. Hincks (12) mentions 

 these last as present on some of his specimens, therefore there does not seem sufficient 

 reason for separating the two forms. The avicularia are large, placed on the outer 

 sides of the zooecia, and have long mandibles. Ooecia are present in the position usual 

 for the species. 



Localities : Palk Bay ; and Gulf of Manaar. 



Beania mirabilis, Johnston.

Family : CELLARIID^E. 

 Cellaria johnsoni, Busk.

 Watering Point, 34 fathoms.
