130 Mr. F. E. Bedclartl on the 



Rhododrihis minutus * is tlie only member of tlie familj 

 known from that country; but 1 liave specimens of anotlier 

 (untlcscribcd) species, and if Captain Ilutton is ri<;htt in 

 referring liis Lumhricus hcvt's and L. uUginosus to Perrier's 

 genus Digastevy we have a third Cryptodrilid genus in New- 

 Zealand. ^^ Hypoga'on orthostichon " is not referable to either 

 IlhoJodrilus or Cryptodrilus. It seems nearest perhaps to 

 Y\c\c\\<dY^ s, \ Notoscolex { = Megascoltdes, M'Coy). I am not 

 at all certain that it belongs to that genus, for the definition 

 given by Fletcher is not at all satisfactory ; indeed the 

 discrimination of the genera of Cryptodiilidaj is unquestion- 

 ably the most difficult part of the classification of the 

 Uligochffita. 



As 1 do not wish, pending a revision of the Cryptodrilidse, 

 to add unnecessarily a new generic name, I shall describe 

 fc)chmarda's species as 



(9) Megascolides orthostichon (Schm.).

I do not attempt to give here anything more than the most 

 obvious characters, as I could only dissect one specimen, 

 which I have been careful to injure as little as possible. 



The seta3 are in eight equidistant rows. 



The elitellum is a complete girdle, and occupies segments 

 xiv.-xvii. inclusive. 



The male pores are upon segment xviii. ; there appear to 

 be no genital papilla? developed in their neighbourhood or 

 anywhere else upon the body ; the male pores correspond in 

 position to the ventralmost setai. 



The gizzard is in segment v. 



The nephridia are apparently of the " dift'use " type ;t hey 

 were not at all obvious. 



The sperm-sacs are in segments x., xi., xii. 



The ovaries are in segment xiii. The receptacula ovorum 

 arc ])resent and occujiy the usual })osition in segment xiv. 



Ihe atria are short and tubular in Ibrm ; the chief part of 

 the atrium is a white glandular tube which communicates 

 with the exterior by a very short muscular duct. There 

 appear to be no penial sette.
