Vomeriila esperioides, Ridley and Dendy [15, p. 60, pi. xii. fig. i, pi. xvii. figs. 



2, 4, 12]. 



One large conical specimen resembling in size and shape 

 the type specimen, figured in the Challenger Report {loc. cit.) 



Locality. — South-east of Cape Colony, 47 fms. 



Distribution. — Agulhas Bank, 150 fms, and off Rio de la 

 Plata, 600 fms. (" Challenger ").

Plate v., Fig. 18. Plate VI., Fig. 19a, b. 



Sponge club-shaped, with expanded, flattened upper end, 

 presenting several circular oscules, each subdivided by partitions 

 and with raised rims. 



Consistence firm. Surface smooth. Colour dark brown. 



Skeleton consisting of a central loose network of slender 

 spiculo-fibre surrounded by a hard rind, and with a dermal 

 layer of tangential oxeas not united into bundles ; loose 

 scattered oxeas in the choanosome. 



Spicules. — Oxea, 190 x 9 /*, slightly curved, terminating 

 abruptly in sharp points. 



Locality E. — Off Cone Point, Natal, 34 fathoms ; bottom, 

 broken shells. 



The one specimen representing this species is 6 cm. high, 2 

 cm. in diameter at the base, and 5 cm. in diameter at the flat 

 summit. The specimen, which apparently has been torn from 

 its attachment, reveals a loose network in the interior ; the torn 

 skeleton fibres form long loose shreds. There are three oscules 

 with rims, the largest being 6 mm. in height, 10 mm. in 

 diameter, and with nine circular sub-divisions ; some smaller 

 oscules are almost flush with the surface. 



The new species is near P. cohtxrcns, Carter [5, p. 446], from 

 Port Phillip, but the latter is narrower at the summit than at 



* ivftiTos, with fine threads.
