In regard to Turbellaria, Mr. F. W. Gramble while working at tlie 

 Port Erin Biological Station last summer drew up a list of the species 

 found in the neighbourhood. This has been published in full in ' Trans. 

 Liverpool Biol. Soc.,' vol. vii. pp. 148-174. The list contains records of 

 twenty-eight species, representing twenty-three genera. Of these the 

 following live species are new to British seas : — Promesostoma ovoideum, 

 P. lenticulatum, Byrsophlebs intermedia, Plagiostoma sulpliureum, Oligo- 

 ■cladus sangninolentus. 



The PoLTZOA collected on the various expeditions have been examined 

 by Miss L. R. Thornely, who reports that amongst the many forms col- 

 lected, amounting to about eighty-one species, three at least are new 

 records to the district, viz., Aleyonidium mamillatum, Palmicellaria Skenei, 

 and Lepralia edax. 



The COPEPODA obtained both by surface nets and also from the mud 

 and other material from the dredge have yielded Mr. Thompson in all 

 136 species, of which eighteen are new records to British seas and eleven 

 are new to science. These last are : — Ameu-a attenuata, Cletodes monensis, 

 Herdviania stylifera, Cyclops marimis, Hersilioides Puffini, Jonesiella 

 kycsnce, Laophonte spinosa, Lichomolgus maximus, Monstrilla longicornis, 

 Stenhelia denticulata and 8. hirsuta. These new species are all described 

 in full, and figured, in Mr. Thompson's ' Revised Report upon 

 the Copepoda of Liverpool Bay,' just published (August 1893) in 

 ' Trans. Liverpool Biol. Soc.,' vol. vii., so it will perhaps be sufficient 

 for the purposes of this report to state the localities at which the new 

 species and those new to British seas were obtained, as follows : — 



Labidocera acutum, Dana, off Puffin Island, 10 fathoms, dredo-ed. 



EucluBta marina, Prest., in ascidian, Garwick Bay. 



Herdmania stylifera, LC.T., 12 miles west of Port Erin, 39 fathoms, 

 in mud. 



Cyclops marinus, I.C.T., 20 miles off Southport, 20 fathoms, dredged. 



Oiardella Callianassce, Canu, Liverpool Bay, surface. 



Hersilioides Puffini, I.C.T., off Puffin Island, surface. 



Stenhelia denticulata, LC.T., in Port Erin, 5 fathoms, mud. 



Stenhelia hirsuta, LC.T., 12 miles west of Port Erin, 39 fathoms, mud. 



Ameira attenuata, LC.T., in Port Erin, 7 fathoms, mud. 



Jonesiella hymnce, LC.T., in Port Erin, 5 fathoms, mud. 



Laophonte spinosa, LC.T., in Port Erin, 7 fathoms, mud. 



Cletodes monensis, LC.T., 12 miles west of Port Erin, 39 fathoms, 

 mud. 



Monstrilla Dana, Clap., off Puffin Island and off Port Erin, surface. 



Monstrilla longicornis, LC.T., off Puffin Island, surface. 



Monstrilla rigida, LC.T., off Puffin Island, surface. 



Lichomolgus maximus, LC.T., in Pecten, off Port Erin, 20 fathoms. 



Sabelliphilus Sarsii, Clap., on Sahella, Beaumaris and Puffin Island. 



Artotrogus orbicularis, Boeck, Puffin Island, shore. 



It will be noticed that one of the above new species has required the 

 formation of a new genus, which Thompson has named Herdmania.^
