Limnsea truncatula Miiller. — Borough ; Woolacombe. on the 

 leaves of Iris pseiidacorus. [Braunton by Mr. Champion]. 



var. minor Moq.-Tand. — Borough, at the edge of little streams. 

 Numerous. Confirmed by Mr. J. W. Taylor. 



[Planorbis spirorbis Miiller var. leucostoma. — This variety 

 was identified by Mr. J. W, Taylor. Braunton, by Mr. Champion. 

 Not in last Census, and though recorded in Victoria History, no 

 locality is given. The species was also found at the same place by 

 Messrs. Beeston and Wright]. 



Pomatias elegans Miiller \=^Cyclostoma KwzM\ — Woolacombe, 

 on the golf-links. Many dead specimens taken in 1906-7. In July, 

 1908, tlie Rev. C. Chichester brought me four living specimens from 

 the golf-links, and informed me that he had frequently taken them 

 alive before. I afterwards found six others on a different part of the 

 links. There had been rain in the morning, which had evidently 

 induced them to come to the surface, and they were lying mouth 

 downwards, partially buried in the sand under privet and herbage. 



Sphaerium lacustre Miiller var. ryckholtii Norm. — Damage, 

 pond. Variety identified by Mr. J.W. Taylor. Abundant in company 

 with Pisidium casertanum Poli. Not recorded in the last Census. 

 [Braunton Burrows is the only locality given for the species in North 

 Devon in the Victoria History, and Messrs. Beeston and Wright state 

 that they found it scarce in the dykes near there]. 



[Pisidium subtruncatum Malm \=P. fonti?iale Jeffreys]. — 

 Saunton, ditch ; Braunton].

 writers, and also P. cifiereti>n Alder]. Twitchen, pond in garden ; 

 Woolacombe, pond ; extremely abundant at Damage ; near Ben- 

 nett's Mouth and Borough Stream. The specimens from these two 

 last localities are stated by Mr. B. B. Woodward to be more roundly 

 oval than usual. [Saunton, ditch. The largest specimen taken 

 measures 5'o mm. in length and 5*5 mm. in breadth. Mr. B. B. 

 Woodward remarks that many of the specimens from this locality are 

 remarkably thick, heavy and tumid]. 



[Pisidium nitidum Jenyns. — Saunton, ditch]. 



Pisidium obtusale Pfeififer. — Woolacombe, pond. 



Pisidium gassiesianum Dupuy. — Twitchen, pond in garden. 

 [Braunton, by the Rev. C. Chichester]. 



Pisidium personatum Malm. — Church Close, stream, numer- 

 ous ; Borough, stream ; Borough, pond. [Also specimens from 

 ditches at Braunton and Croyde are probably this species]. Mr. 

 B. B. Woodward considers all the specimens more oval than the type.
