 and turtles.

Placobdella hoUensis I Whitman). 



A single specimen colored exactly on the pattern of liraf's figure and with typical annulation and 

 eyes was taken at East Swamp, Rondeau, Ontario, August 28, 1899. 



Many examples of this species are provided with cutaneous papilla almost as large and rough as 

 those of /-*. rugosa, and it is often difficult to assign examples to one or the other species. Generally 

 the eyelike character of the anterior dorso-medlan sensillse is sufficient and this species is seldom so 

 broad and flat, nor is the lack of agreement of the dorsal and ventral furrows so evident as in P. rugoia. 



Placobdella montifera nom. nov. 



This is the sjiecies known in my paper on the Hirudinea of Illinois as Ileiiiiclepsis carinala (Ver- 

 rill). The resemblance to one species of HemUiepsis is entirely superficial and the name carinata has 

 been already used by Grube for a species of this genus, requiring that a new one be coined. In the 

 character of its papulation, the incipient subdivision of its annuli, and the papillse of the posterior 

 sucker, which are very small and number 110 or more, this species approaches Actiitobddla. The form 

 of the broadly expanded head is, however, distinctive of it among the known species of leeches of 

 North America. 



(379(() Long Point, Canada, Avigust 28, 1899; from rice grass. 



(403-0 I^ong Point', Canada, September 24, 1899. 



Placobdella phalera (Graf). 



Several specimens of a small leech which is rather doubtfully referred here conform closely with 

 tiraf's account of the arrangement of pigment, reserve cells, and other features of P. phalera. Two <«f 

 the most striking characters 6i the species are the strongly developed band of reserve cells, apjiearing 

 on the surface as a white or pale-yellow stripe, which extends entirely across the neck at somite VI, 

 and the serrated margin of the posterior sucker, which has a circle of small papillse as in AcliiinhilcUa 

 anneclew, but lacks the definite agirreu-ati'l u'lan^N. 



(178a) Ea-st Harbor, near LakeM^li-, (i|,i,,. AiiL'u:^t4, 1899; from flag leaves. 



(196a) East Harbor, Sandusky, nhi,,, Aii-nst 7, 1899. 



(324a) Long Point, Canada, August 16, 1897. 



Actinobdella annectens sp. nov. (text tigs. 1 and 2). 



Most interesting of the leech collections is a specimen, fortunately well preserved, of a new species 

 of Actinobdella which, together with an example of A. inequianmilala described in the Report on the 

 Leech Fauna of Minnesota, clearly shows that this genus belongs to the Glossiphonidte and not to the 

 Ichthyobdellidse as I was erroneously led to suppose from a knowledge of the superficial characters alone
