the possibility that two distinct forms of the diadema type, a 

 small and a large, occur in Ceylon, in Avliich case the name 

 lankadiva belongs to the former. So long as this remains 

 imcertain;, I prefer to use Kelaart's name for the form here 

 under consideration. 



Hipposiderus euotis, sp. n. 



Diagnosis. — Facial portion of skull broad : anteorbital 

 Avidth' 10-3-10-6; teeth moderate: upper row 13-2-13-7. 

 Ears large : width 29-29'8 * ; size rather moderate : forearm 

 84-5-89-2. 



Details. — The skull of this species bears a certain resem- 

 blance to that of H. lankadiva ; it is of about the same size, 

 Avith very "nide temporal fossse (large zygomatic width), and 

 with approximately the same shape and development of the 

 sagittal crest ; but the facial portion is considerably broader, 

 the region between the nasal sw'ellings and the sagittal 

 crest distinctly hollowed out, as in H. diadema, not convex 

 or flattened as in H. lankadiva. The teeth are markedly 

 smaller than in this latter. 



The shape of the posterior leaf is as in //. diadema. 



Type. — Young adult (apparently full-grown), skin. Bat- 

 chian. Collected by Dr. A. R. Wallace. Tomes Collection 

 (unregistered), 



Hipposiderus dinops, sp. n. 



Diagnosis. — Facial portion of skull excessively broad : 

 anteorbital width 1 1 ; teeth very large : upper row 14*6. Ears 

 excessivelv large : width 32"5 j size the extreme : forearm 

 96-5. 



Details. — The ^kuU is of the same size as in H. lankadiva, 

 or rather larger, but the facial portion is much broader, 

 the legion behind the nasal swellings distinctly concave ; the 

 coronoid process of the mandible markedly higher and 

 broader. The premolars and molars are as in //. lankadiva, 

 but the upper canines much broader at base. 



The lower leg is extraordinarily lengthened : 44 mm., as 

 against 35"8 in the largest //. lankadiva. The tail, too, is 

 markedly longer. The third leaflet external to the horse- 

 shoe very small. The upper border of the posterior leaf as 

 in euotis and diadema. 



Type. — ? ad. (in alcohol). Rubiana f:, Solomon Islands. 

 Collected by C. M. Woodford, Esq. Brit. Mus. no. 88. 1.5.22. 



* Measurements from two dried skins, therefore probably a little too 

 small. 



t A minute islet very near the western coast of New Georgia (see 

 map in C. M. Woodford, ' A. Naturalist among the Head-hunters,' 



London, 1890).
