MoLGULA, sp. A few specimens were dredged between the Salstone 

 and Snape's Point, and also on the shell-gravel of the " Bag " at the 

 mouth of the Kingsbridge estuary. 



Styelopsis grossulahia {van Bcneden). A few small specimens 

 attached to shells, etc., were dredged in the channel west of the Salstone. 



Phallusia mammillata {Gnvier). A few specimens were found on 

 the shore on both sides of the Salstone. 



AsciDiELLA ASPERSA {0. F. Milllcr). One of the commonest ascidians 

 in the Salcombe estuary. It was found on the shore on the Salstone 

 and on the zostera banks at the north-east end of Salcombe Harbour. 

 At the end of September, 1898, A, asioersa were extremely abundant 

 on these banks, whereas during the present summer (1900) they were 

 found only occasionally. On the zostera banks the specimens were met 

 with in clusters of two or three together lying on the surface of the 

 bank, but not attached to it in any way. Many specimens were 

 obtained by dredging in the Kingsbridge estuary, and it was also 

 dredged, though in less abundance, in Salcombe Harbour. 



AsciDiELLA SCABRA {0. F. Midler). Common in dredge material 

 from the Kingsbridge estuary, especially in the channel between Salstone 

 and Snape's Point. Dredged also in Salcombe Harbour. 



Perophora Listeri, Wiegm. Growing on shells dredged from the 

 channel west of the Salstone. 



Clavelina lepadiformis, 0. F. MuUcr. Very common on the shore 

 on the west side of the Salstone, attached to stones, less common on 

 the south-east side. It was also found on the rocks at the mouth of 

 Salcombe Harbour. 



BOTRYLLUS violageus, H. M.-Ediu. On stones and rocks at the 

 mouth of Salcombe Harbour. It was scarce on the shore at Salstone, 

 and was not found elsewhere in the estuary. 



Amaroucium Nordmanni, M.-Edio. On the shore at the Salstone in 

 company with Morchellium argus, but not plentiful. The specimens 

 were recognised and identified by Mr. Garstang. 



Morchellium argus, M.-Fdw. Very abundant on the harder parts 

 of the shore in the Kingsbridge estuary, attached to stones and gravel. 

 It was a striking feature of the fauna on the muddy gravel forming the 

 south-east shore of the Salstone, and was plentiful on the western side 

 also. In Salcombe Harbour it was occasionally met with on the zostera 

 banks, but became less frequent as the mouth of the harbour was
