Fig. 5. Lagena marginata (Walker and Jacob), var. catemdosa, nov. (p. 28) : 



a, lateral aspect (at jyp are shown parasitic-alga-borings in the shell- 

 flange) ; b, oral aspect, x 17. 



6. Nodosaria {DentaUna) soluta, Eeuss. var. mthaculeata, nov. (p. 3). X 10. 



7. Bilocuiina tubu/osa, Costa (p. 7). An abnormal specimen with two 



apertures. X 16. 



8. Amphisteghia radiata (Fichtel and Moll) (p. 45) : a, lateral aspect ; 



b, peripheral aspect. X 1(1. 



9. A. radiata (F. & M.) (p. 45). A transverse section showing the asymme- 



trical habit of growth in the successive layers of whorls, the non-tubulate 

 umbonal centres, and the somewhat irregular overlapping of the 

 whorl-layers on both sides of the shorter axis. X 14. 



10. A. radiata (F. &M.) (p. 45). Small portion of a median horizontal section 



of the test, showing at a a two septa traversed by the canal-system ; 

 below this at b is the marginal cord of the preceding whorl with its 

 canal-system. X 135. 



11. A. hauerina, d'Orbiguy (p. 46). Part of a septum, showing interseptal 



canals at a. This is taken from a typical fossil specimen of Amphi- 

 stegina from the Vienna Basin, for comparison with the recent form, 

 A. radiata (F. & M.). X 520. 



12. A. radiata (F. & M.) (p. 45). One of the chambers of the peripheral 



whorl in a median horizontal section, enclosing a young individual 

 consisting of two chambers. X 135. 



2. An Enumeration of the Hemiptera-Homoptera of the 

 Island of St. Vincent, W.I. By P. R. Uhler. 

 (Communicated by Dr. D. Sharp, F.R.S., F.Z.S., on 

 behalf of the Committee for investigating the Flora 

 and Fauna of the West-Indian Islands ^) 



[Receiyed Noyember 16, 1894.] 



The Homoptera of St. Yincent, collected by Herbert H. Smith, 

 constitute an assemblage of forms mostly small and neat, which offer 

 a striking contrast to the large and showy insects that inhabit the 

 regions of the South-American continent a few hundreds of miles 

 away. It is not, however, to this nearest part of the continent 

 that we must look for the source of distribution from whence this 

 assemblage was derived. The Mexican character of the fauna 

 seems unquestionable. 



Fam. CiCADiDiE. 



Genus Proarna, Stil. 



Pboarna hilaris. Germ. Silb. E,ev. Ent. ii. p. 69, 34. 



Numerous specimens were collected at various localities in the 

 island. The individuals are of different sizes, the males being

 Uhler in the P. Z. S. 1893, pp. 705-719, and 1894, pp. 156-160. The species of 

 MembracidiB, described by Dr. Goding, and mentioned jiostea p. 57, form also 

 part of the collections transmitted by the Committee to N. America for 

 examination. — D. S.]
