NOTES ON VERONICELLA In Journ. Institute of Jamaica, Vol. 

 '2, p. 1)01 (1899), Mr. H. Vend ryes publishes without descriptions the 

 names of two varieties of V. sloanii credited to me. I had not in- 

 tended to publish these names, as they seem to represent mutations 

 only, but since they are published, it may be well to explain that v. 

 maculata is F, No. 24, and v. subpalllda is G, No. 20, of Ckll. & 

 Larkin's paper on the Jamaican species of VeroniceUa in Journ. of 

 Malacology, Vol. 3, pt. 2, 1894. Mr. Vendryes lists Limacettus 

 lactescens from Jamaica, but it belongs to North America, and has 

 not been found in the West Indies. When the locality of it was 

 unknown, 1 guessed that it might possibly have come from Jamaica, 

 along with the VeroniceUa described at the same time by Blainville. 

 Dr. Simroth has lately (cf. Zool. Record for 1898, Mollusca, p. 62) 

 applied the name decipiens to an African VeroniceUa. This must be 

 changed, as Semper has used the same name for a South American 

 species. T. D. A. COCKERELL. 



My friend, F. W. Kelsey, of San Diego, Cal., recently sent me a 

 peculiar Lithophagus, taken near that city, which I at once recog- 

 nized as a Myoforceps, and Dr. Dall afterwards kindly determined 

 the species as M. aristatus Dillwyn. The finding of this interesting 

 species, with its elongate, crossed ends, in shell ground which has 

 been well worked for so many years, is worthy of note and to the 

 credit of the enthusiastic collector named. The fact that mature 

 specimens are found imbedded in hard rock is proof that it is not of 

 very recent introduction. FRED. L. BUTTON.

SYNOPSIS OK THE RECENT AND TERTIARY LEPTONACEA OF 

 NORTH AMERICA AND THE WEST INDIES. By WM. H. DALL. 

 (Proc. U. S. Nat. Mus., vol. xxi., pp. 873-897, plates 87 and 88, 

 1899.) 



" The Leptonacea form a very interesting and puzzling group. 

 Their characters combine features characteristic in other Teleo- 

 donts of immaturity, with such as are more probably due to environ- 

 mental modifications. Without being in themselves prototypes, they 

 exhibit features which we may readily suppose might have been 

 characteristic of prototypic Teleodonts. Groups which are really
