130 Mr. F. E. Beddard on the 
Rhododrilus minutus * is the only member of the family 
known from that country; but I have specimens of another 
(undescribed) species, and if Captain Hutton is right} in 
referring his Lumbricus levis and L. uliginosus to Perrier’s 
genus Digaster, we have a third Cryptodrilid genus in New 
Zealand. “Hypogieon orthostichon” is not referable to either 
Ithododrilus or Cryptodrilus. Jt seems nearest perhaps to 
Fletcher's {| Notoscolex (= Megascolides, M‘Coy). I am not 
at all certain that it belongs to that genus, for the definition 
given by Fletcher is not at all satisfactor ; indeed the 
discrimination of the genera of Cryptodrilide is unquestion- 
ably the most difficult part of the classification of the 
Oligocheeta. 
As I do not wish, pending a revision of the Cryptodrilide, 
to add unnecessarily a new generic name, I shall describe 
Schmarda’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 sete are in eight equidistant rows. 
The clitellum is a complete girdle, and occupies segments 
X1Vv.-xvil. inclusive. 
The male pores are upon segment xvili.; there appear to 
be no genital papillae developed in their neighbourhood or 
anywhere else upon the body; the male pores correspond in 
position to the ventralmost sete. 
The gizzard is in segment v. 
The nephridia are apparently of the “ diffuse ” type ;t hey 
were not at all obvious. 
The sperm-sacs are in segments X., X1., Xi. 
The ovaries are in segment xii, The receptacula ovorum 
are present and occupy the usual position in segment xiv. 
‘Lhe atria are short and tubular in form ; 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 sete.
