6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



Gorter and Van der Vlerk (25, p. 104) identify specimens of 

 Lcpidocyclina occurring in material 1116 and 1120 as L. (Nephro- 

 lepidina) umrginota Michelotti. These specimens are not L. (Nephro- 

 lepidina) marginata but are L. (Lepidocydina) sanluisensis, n. sp. 

 As is stated in the discussion of L. sanluisensis, n. sp., this species 

 closely resembles L. (Ncphrolepidina) marginata in form and surface 

 ornamentation, but differs in the character of the embryonic ap- 

 paratus, belonging to Lcpidocyclina s.s., whereas L. marginata is 

 distinctly a NcpJirolcpidina. It is very probable that Gorter and Van 

 der Vlerk may have based their determination upon a specimen with 

 a deformed embryonic apparatus, because one of our specimens from 

 locality 1120 showed an embryonic apparatus which was so deformed 

 as to have a nephrolepidine form. The other sectioned specimens 

 have the true Lcpidocyclina s.s. type of embryonic apparatus and are 

 identical with the cotypes of L. {Lcpidocyclina) sanluisensis, n. sp. 



Helicolepidina spiralis Tobler is reported by Gorter and Van der 

 Vlerk (25, p. 97) as occurring at locality 163. This species may be 

 present, but it was not recognized in our material. 



L. (Lcpidocyclina) pustulosa H. Douville was reported by Gorter 

 and Van der Vlerk (25, pp. 96-97) as occurring at localities 163 and 

 165. Their illustrations seem to be closer to L. {LepidocycVum) trini- 

 tatis H. Douville than to L. pustulosa, especially plate 12, figure 8. 



Lepidocydina occurring at localities 469 and 476, reported by Gorter 

 and Van der Vlerk (25, p. loi) as ''Lepidocydina sp. (small speci- 

 mens)", are L. {Lepidocydina) canellei Lemoine and R. Douville. 



The several species of AsterocycUna specifically identified by Gorter 

 and Van der Vlerk are from localities not represented in our 

 collections.
