Lagena juddiana, sp. nov. (Plate 54. fig. 7.) 



Description. — This species is allied to Lagena striatopunctata, Parker and 

 Jones *, but is more elaborate in the surface-ornament. The perforations on 

 the riblets are triangular, each being partially closed by a pointed or cusp-like 

 valve. Beneath each perforated area there is a depression or excavation. 

 The intercostal area is a moderately deep groove. Length of figured 

 specimen '725 mm. ; greatest width "5 mm. 



I have much pleasure in naming this interesting species after Professor 

 J. W. Judd, C.B., to whom I am especially indebted for the privilege of 

 working out portions of the material from Funafuti. 



Occurrence. — Sta. 13, 1050 fms. Two examples.
