758 SUMMARY OF CURRENT RKSEAROHES RELATING TO 



in Baird's Catalogue as a species of Von Siebold's, does not appear to 

 have ever been described ; the author now gives an account of it. 



Helminthological Notices* — Dr. Sonsino has given an account of 

 the entozoa of the Long-eared Fox (Megalotis cerdo) of Egypt. Among 

 them are Taenia echinorhynchoides sp. n., on the rostellum of which there 

 are twelve to sixteen transverse rows of hooks similar to those of T. 

 cucumerina ; Echinorhynchus pachimithus, which is much smaller than 

 E. gigas ; Pliysaloptera cesticillata and HeteraJcis crassispiculum spp. nn. 

 A larval form of cestode fuund in the subcutaneous connective tissue of 

 the Jackal (^Canis aureus) is suspected to be the young oi Boihriocepiialus 

 Mansoni. 



Tristomum elongatum-j — Prof. M. Braun makes some additions and 

 corrections to v. Baer's description of this Trcmatode. The excretory- 

 organs open by a large flask-shaped vesicle in the region of the pharynx ; 

 numerous fine anastomosing vessels may be easily seen in the anterior 

 transparent parts of the body, but ciliated infundibula could not be 

 detected. All the vessels are, on each side, collected into an anterior 

 and posterior primary trunk, which open separately into the base of the 

 excretory vesicle. In front of the pharynx the brain may easily be seen, 

 as well as four thick nerve-trunks, which soon break up into anastomos- 

 ing branches and supply the very mobile anterior part of the body; 

 posteriorly there arise two thick trunks, which soon bifurcate and can be 

 followed to the hinder end, where they pass into the sucker. There are 

 two larger and two smaller black eyes on the brain. Numerous yolk- • 

 follicles are to be found among the enteric aijpendages ; they pour their 

 secretion into two anterior shorter, and two posterior and longer yolk- 

 ducts ; the latter unite and pass into the yolk-reservoir, which lies in 

 fj'ont of the ovary ; from this a canal takes a somewhat winding course 

 to the uterus. In front of this last lies the cirrus, the nature of vsrhich 

 was misunderstood by von Baer. No vagina could be found in the fresh 

 animal, and the author doubts whether one is present. Further, histo- 

 logical, details are promised.

Anatomy of Dinophilus.J — Mr. S. F. Harmer gives an account of the 

 anatomy of Dinophilus tseniatus, a new species found at Plymouth. 

 With regard to the affinities of the genus, the author agrees with pre- 

 vious observers, and especially Weldon, as to its archi-annelid relation- 

 ships. He points out that the presence of two rings of cilia on each 

 segment is common to the new species and to Protodrilus leuckarti. 

 There is a close resemblance in the nervous systems of these two genera, 

 save that that of Dinophilus (like that of Histriohdella, an undoubted 

 archi-annelid) is segmented. The nephridia of D. tseniatus closely 

 resemble those of Protodrilus^ as described by Hatschek. In many of 

 its features Polygordius differs from EinopMlus far more than does 

 Protodrilus, but, on the other hand, Histriohdella is probably more 

 closely related to Dinophilus than is Protodrilus. Although it seems so 

 clearly an archi-annelid, we may agree that Dinophilus gives evidence of 

 having been derived from Platyhelminth-like ancestors. In the per-
