Bessell, J. B., Some rare and curious diatoms. (Journ. Tor- 

 quay nat. Hist. Soc. I. 1. 1909. p. 13—14.) 



The author enumerates several diatoms of interest found by 

 him near Torquay last summer. They are: Achnanthidium flexel- 

 lum Breb., Gomphonema intricatufn Kutz., Achnanthes coarctata 

 Breb., and Navicula pusilla W.Sm., at Anstey's Cove. On the moors 

 at Moretonhampstead were found Pinnidaria acrospheria Breb., 

 P. suhcapitata Greg., Gomphonema subclavattim Grün., and some 

 unusually large specimens of Navicula elliptica. Several species scarce 

 on the Devon coast were found at Corbyn's Head, as well as the 

 spore form of Chaetoceros, formerly known as Syndendriiini dia- 

 dema Ehr. E. S. Gepp.

 Dominica, British West Indies. (Trans. Proc. bot. Soc.

This Short paper contains the first published record of marine 

 algae from Dominica. Twenty species are enumerated, as well 

 as a few varieties, none of which are new. The specimens were 

 named by Mr. E. M. Holmes, who has added a few notes.

 Island. (Journ. Bombay nat. Hist. Soc. XIX. 3. November 1909. 

 p. 762-763.) 



The author gives an account of two monoecious species found 

 in ponds by rice-fields at Matunga during the rainy season. One 

 of these grows associated with the aquatic plant, Hydrilla verticillata, 

 and with Oedogoniutn sciitatiim, and is referred to Chara verticulata 

 Roxb. The other species is not gritty or brittle, and is referred to 

 Chara ßaccida A. Braun. - E. S. Gepp.
