 Richard Owen, Esq., in the Chair. 



Living specimens were exhibited of a species of Bee from South 

 America, together -vvith portions of its Comb, contained in the fissure 

 of a log of wood. They were presented to the Society by Mr. Bigg, 

 who stated, in a note accompanying the specimens, that they were 

 found about three weeks since on spUtting a log of peachwood from 

 the Brazils for the use of a dye-house, on the premises of Mr. Apple- 

 gath, a calico-printer at Crayford in Kent. The wood had been 

 previously lying in the docks, and had been perhaps eighteen months 

 from the Brazils. 



Mr. Curtis, to whom specimens were submitted for examination, 

 States that they belong to the genus Trigona, Jur., and form a very 

 pretty and apparently undescribed species. 



Mr. YarreU exhibited preparations of both sexes of Syngnathus 

 AcuSylAvva.., and Syngn. Typhle, Ej., in illustration of the follo\ving 

 extract from the manuscript notes of the late John Walcott, Esq., 

 author of ' A Synopsis of British Birds,' ' History of Bath Fossils,' 

 and ' Flora Britannica Indigena.' This manuscript, which is volu- 

 minous, and relates wholly to British Fishes, was viTitten during the 

 author's residence at Teignmouth, in the years 1784 and 1785, and 

 has been forwarded by his son William Walcott, Esq., of South- 

 ampton, to Mr. Yarrell, for his use in a projected work on ' British 

 Fishes.' 



" Syngnathus Acus and Typhle. — The malė differs from the female 

 in the belly from the vent to the tail fin being much broader, and in 

 having for about two thirds of its length two soft Haps, which fold 

 together and form a falše belly. They breed in the summer, the fe- 

 males casting their roe into the falše belly of the malė. This I have 

 asserted from having examined manj^ and having constantly found, 

 early in the summer, roe in those without a falše belly, but never any 

 in those with ; and on opening them later in the summer there has 

 been no roe in (what I have termed) the female, but only in the falše 

 belly of the malė." 



The specimens exhibited of females of Syngn. Acus and Typhle had 

 no anai pouch, and the opened abdomen exposed two lobes of ova 

 of large size in each. The anai pouch is peculiar to the malęs, and 

 is closed by two elongated flaps. On separating these flaps and ex- 

 posing the inside, the ova, large and yellow, were seen lining the 

 pouch in some specimens, while in others the hemispheric depres- 

 sions from which the ova had been but lately removed were very 

 obvious. In each of these the opened abdomen exhibited true testes. 



Mr. Walcott adds : "They begin to breed when only betv^een 4 

 and 5 inches long." A specimen oi Syngn. Acus, nearly 1 6 inches long, 

 wa8 exhibited, indicating, probably, its extreme growth. A female
