from each side of the abdomen, forming a little semicircular 

 row of oblong horny teeth. I am not aware whether its 

 note is considered musical or not, but my friend informs 

 me it is very loud and like a police whistle. I am 

 unable to say whether its life-history is known or has been 

 recorded, the literature at my disposal affording but scanty 

 information." 



Mr. Main exhibited his method of holding a twig with 

 larvae or imago in position for photographing. It consisted 

 of a compound clamp or test-tube holder used in chemical 

 experiments and an ordinary retort stand. He showed how 

 the twig could readily be moved in either a horizontal or 

 vertical plane or rotated. He also exhibited an appliance 

 (ball and socket joint) for fitting on the camera stand, to 

 allow of the inclination of the camera in any direction with- 

 out or with extremely little adjustment of the legs of the 

 stand. 



Mr. Step exhibited, on behalf of his daughter Miss Mabel 

 Step, a remarkable flower of the common primrose. It was 

 an amalgamated series of flowers in one ; the parts were in 

 thirteens, 13 stamens, 13 sepals, and 13 petals. The stigma 

 was short, with a bilobed disc at the summit. He also 

 showed specimens of the uncommon fungus Hirneola auricida- 

 judcea, or Jew's ear fungus, from the Mickleham Downs, 

 where he had not met with it before. It was attached to 

 dead elder stems. 



Mr. Manger read a paper, "The Echinoderms " (see 

 page 10). 



APRIL 2-jth, 1905. 



The President in the Chair. 



Mr. Harrison exhibited living larvae of Agrotis ashworthii 

 from N. Wales, and gave an account of the larval habits. 



Mr. Turner exhibited a specimen of the cristated form of 

 Sedum reflexum. Mr. Step said that this species of Sedum 

 was prone to variation, and this form was known as the 

 " cockscomb stonecrop." He also remarked that the normal 

 form occurred in several places in Surrey, but that probably 

 it was not indigenous in this part of the country. Mr. 

 Turner also showed cases of Coleophora saturatella on broom 

 twigs ; he thought they were probably the cases of last 

 year's larvae from which the imagines had emerged.
