 fortiter sat crebre'piinctatis, fascia rufa ante medium ad suturam

This species is very close to C, (ethiops^ but is relatively 

 narrower and has the elytra a little more acuminate at their 

 apex. The thorax has a strongly marked, impressed, trans- 

 verse line in front of and behind the disk, so that the disk is 

 more convex than in C. cetMopSj somewhat shining, with a 

 median impressed line; the sides of the disk with some rather 

 large deep punctures. The elytra are clothed with short 

 pubescence, but the rather coarse and moderately close 

 punctuation is nevertheless visible, especially at the base ; 

 just before the middle there is a bright red fascia, nearly 

 rectilinear posteriorly, but obliquely narrowed anteriorly near 

 the suture, where there is a slight interruption. 



XIII. — On the Organization of the Gy prides. 

 By Prof. Carl Claus *. 



Since the publication of Zenker's well-known Monograph 

 (1854), although the number of forms described as species 

 and the division of the old Miillerian genus Gypris into sub- 

 genera and new genera have advanced considerably, our 

 knowledge of the organization of the freshwater " Ostracoda " 

 has made no particular progress. With the exception of my 

 little treatise on the developmental history of Gypris^ pub- 

 lished twenty-two years ago, and the recently issued memoirs 

 of some pupils of Weismann's (Stuhlmann, Nortquist) on the 

 so-called mucous glands, recognized as an ejaculatory appa- 

 ratus, of the male Cyprides, we stand essentially on the plat- 

 form of Zenker's Monograph, and for information on the details 

 of organization are compelled to go to that work, which, not- 

 withstanding the imperfect methods of investigation prevalent 

 at the time of its publication, furnished many important 

 results. Nevertheless it does not come up to the present level
