The South African Hirudinea. 315 



HIRUDO MORRISII sp. nov. 



Locality. Wit Eiver, Bain's Kloof, Wellington. 



Diagnosis. Body flattened and elongate in living condition. 



Dorsal surface greenish brown with seven dark bands continuous 

 along the length of the body, the outermost on each side broader 

 than the others. 



Papillae not very distinct in living condition, two in each of outer- 

 most dark bands, one in dark band within this, and a fourth to the 

 outer side of the median dark band. 



Ventral surface slate colour, the ventral surfaces of anterior and 

 posterior suckers much lighter. 



Outermost limits of dorsal surface, where it meets ventral surface 

 ornamented with a prominent yellow band. 



Two specimens of this species were obtained and kept alive for 

 some time. The specimens eventually died in an expanded condi- 

 tion, but appear to have a much greater body depth than when 

 alive. 



Greatest length 46 mm. 



,, breadth 4-5 ,, 



depth 3-3-5 ,, 



Posterior sucker (longitud.) 3'5 ,, 



(transv.) 4 



The species is quite distinct from H. septemstnata ; indeed the 

 only point of resemblance concerns the number of dorsal dark 

 bands. 



HIRUDO NOTABILIS, sp. nov. 



Locality. Ceres, Cape Colony. 



Diagnosis. Body distinctly flattened and very broad. (Killed 

 condition.) Dorsal surface yellowish brown with seven very pro- 

 minent dark bands extending along the whole length of the body. 

 On either side of the median band in the middle and posterior region 

 of the body is a discontinuous faint dark band which merges at 

 intervals into inner side of the main band on its outer side. 



Papillae distinct in the preserved specimens, one in each outermost 

 lateral band and one in each band on the inner side of this. 



Ventral surface slate colour, the ventral surfaces of the anterior 

 and posterior suckers much lighter. 



Dorsal surface with a broad prominent yellow marginal band. 



A large number of specimens of this species was kindly forwarded
