P. mazatlanica Pfr., ii, 204. 



Section Patulastra Pfr. (44). 



P. massoti Bgt. has been shown to be a Pnnctum. P. luseana 

 Paiva becomes a synonym of P. placida Shuttl., an earlier name. 

 The name luseana is repeated by error at foot of p. 47. P. tenuicos- 

 tata Shuttl. being preoccupied in Helix, Servain calls the species 

 shuttleworthi. 



Section Gonyodiscus (p. 45). 

 Add to list of species, p. 47, the following Palrearctic forms : 



P. machadoiMilne-Ed\v. P. kompsa Mabille.

 P. putrescens Lowe. bot. Gesell. Wien. 1892, p. 27. 



P. ganoda Mabille. 



Section Lyrodiscns (p. 48). 



The type of this group is believed by Wollaston to be a Zonitid. 

 This is not unlikely, but the shells before me are dull, and the 

 animal is unknown. 



Section Lynda Wollaston, 1878. 



Lynda WOLLASTON, Testacea Atlantica p. 382, type H. loweana. 

 Wollaston is disposed to class this elegant, spirally laciniate Pat- 

 uloid snail with the Mad ei ran H. lentiginosa. The single species is 

 from Lanzerote, Canary Is. 



P. loweaua Wollaston: (Not loivei Fer.) 

 torrefacta Lowe not C. B. Ad. 

 usurpans Furtado, iv, 40. 



Section lulus Woll., 1878, 



This (preoccupied) name is proposed by Wollaston (Test. Atlant. 

 p. 326) for the Patula garachicoensis Woll. (H. agrestis Lwe. in lilt.\ 

 a minute form found in Tenerife, Canary Is. It is said to have rela- 

 tions with P. putresceii* Lwe. of Palma, and P. bertholdiana Pfr., of 

 the Cape Verdes. P. garaehicoensis has not been figured, and I have 

 seen no specimens. A variety submarmorata is described by Woll- 

 aston.
