It is most unfortunate that the locaHties from which the types of 

 the above new species were obtained were not specified. 



As parts of the above paper and of the present paper are based upon 

 the same collection, a brief discussion of the major differences in the 

 results is given. 



Figures of surface views and thin sections and the description 

 published by Gorter and Van der Vlerk (25, p. 105, pi. 11, fig. 3) 

 are not L. (Lepidocydina) r. douvillei Lisson, as these specimens have 

 an embryonic apparatus at least twice the size of topotypes of L. 

 (Lepidocydina) r. douvillei Lisson that are in the collection of the 

 Scripps Institution of Oceanography. The figures appear to be L. 

 {Lepidocydina) trinitatis H. Douville. 



The name L. {Lepidocydina) kugleri Gorter and Van der Vlerk 

 appears to have been applied to specimens of L. trinitatis that have a 

 well-developed flange. A study of a large number of specimens of 

 L. trinitatis from locality 163 Venezuela, Soldado Rock, and Bella 

 Vista, San Fernando, Trinidad, shows the presence of a complete 

 series of forms of L. trinitatis ranging from flat, lenticular forms with 

 a narrow flange to highly inflated umbonate types with a wide flange. 

 There appear to be no structural characteristics upon which this series 

 may be divided into two or more recognizable species. L. {Lepidocy- 

 dina) kugleri Gorter and Van der Vlerk, like L. trinitatis Douville 

 var. carribbeanensis Hodson, L. trinitatis var. venesudana Hodson, 

 L. (Lepidocydina) hubbardi Hodson, L. hubbardi var. bolivarensis 

 Hodson, L. hubbardi var. aurarensis Hodson, and L. (Lepidocydina) 

 weeksi Hodson, seem to be based upon individual variations of 

 L. (Lepidocydina) trinitatis H. Douville. 



Gorter and Van der Vlerk (25, p. 99) report the presence of L. 

 (Polylepidina) adkinsi Vaughan in material from localities 1149 and 

 1 1 52. Thin sections of our material from these localities contain no 

 sections which are L. (Polylepidina) adkinsi Vaughan.
