quantity inside old Balonus shells. We devoted some 

 time to Lift or in (i rud 'is and its varieties of which we took 

 a good many, particularly var. globosa. Then the var. 

 elevata of Patella vulgata is very abundant at Port St. 

 Mary. We also took the var. coeridea at the Calf Sound. 

 At Fleshwich we found Patella athletica and H el don

 Trochus helicinus, and Lacuna divaricata, which I took

Messrs. Leicester and Byne have drawn up a paper 

 on the Mollusca round the south end of the Isle-of-Man, 

 which will probably be published soon. 



In addition to the above reports, I may state that — 



(1) Mr. T. S. Lea has continued on two occasions in 

 mid-winter and mid-summer his interesting work in 

 photographing marked areas of rock in the littoral zone 

 in order to compare their condition from year to year and 

 at different seasons. These faunistic photographs have 

 been exhibited as lantern slides to the Biological Society 

 by Mr. Lea. 



(2) Mr. F. J. Cole, during a month's work at Easter, 

 continued his studies on the budding and growth of the 

 colony in compound Ascidians commenced the previous 

 year. He also devoted some time to the collection and 

 preservation of material for his L.M.B.C. Memoir on 

 Sagitta, the Arrow-worm. Now that we are specially 

 looking for Sagitta, we find that it is remarkably variable 

 in its appearances and disappearances, being sometimes 

 very abundant everywhere (we have had a record lately 

 of 90 specimens in one haul), and at other times apparently 

 absent both in surface and bottom waters for days at 

 a time. Sometimes it is to be found by sinking the tow- 

 net when none are present on the surface, and during 

 some night tow-nettings which I took in September I
