Text-fig. 52. Sulculeolaria turgida, posterior nectophore, 'Discovery II' St. 1581, x 11. A, ventral view; B, lateral view. 



[Galetta] Sulculeolaria angusta sp.n. 



The outline of the anterior nectophore (Text-fig. 53 C) has the general Sulculeolaria form. The halves 

 of the long ' mouth-plate ' or lamella of the anterior nectophore have a roundly pointed posterior edge as 

 can be seen in a well-preserved specimen after staining. 1 The somatocyst is minute, but varies in size. 



The profile of the posterior nectophore is long and narrow, without the ' broad baso-ventral sector ' 

 of Bigelow. The lamella of the posterior nectophore is roundly notched as in Galetta chuni, but is 

 thicker in its basal half. About the centre of the mouth-plate appears a variable little prominence. 

 It lies at the terminal end of the thick basal part of the lamella. Between this and the notch is a thinner 

 area. No lateral ridges or wings have been seen, even on well-preserved specimens of the posterior 

 nectophore. 



1 It is generally advisable to stain Sulculeolariinae. With specimens preserved in formalin which has been buffered with 

 hexamine, this may be done fairly quickly, after one or two washes in distilled water, by adding two or three drops of Delafield's 

 haematoxylin to a watch-glass of distilled water.
