Caligus Stromii — StrtJm, Kiobenhavn, Selskabs Skrifter, x. 23. t. 7. 



f. 1-7. 



Female. Carapace oval, the frontal plate somewhat prominent, 

 without sucking discs; thorax about the same length as the carapace, 

 narrower at upper extremity, broader at posterior extremity and ter- 

 minating in two rounded lobes. The horny tubercles on the medium 

 line of the lower portion of thorax above the vulva, large and simple. 

 Abdomen long and narrow, nearly as long as the thorax, terminating 

 in two lobes which give off several short, stout, plumose setae. The 

 sternal fork is short and simple. The oviferous tubes are long. — 

 Length of whole body (exclusive of tubes) half an inch. 



Male. The male is much smaller than the female. The carapace 

 is oval, much larger in proportion to thorax than in female ; thorax 

 narrow and posteriorly notched rather than lobed on each side. Ab- 

 domen much shorter than in female, terminating setse of caudal ap- 

 pendages longer and beautifully plumose. About half the size of 

 femah. 



The Cal. Vcspa (female) of M. Edwards is only 3 lines long and 

 has the carapace narrow in front and very broad posteriorly, while 

 in this species the carapace is almost an exact oval, and the animal 

 (female) is fully half an inch in length. In C Vespa the horny 

 tubercle at base of thorax is small and setiferous, while in this species 

 it is simple and of considerable size. The Vespa is said by M.Edwards 

 to have been found in the gills of a salmon. This species I found on 

 different parts of the body of the fish ; and I have since then received 

 specimens from Dr. Johnston, who found them also on the body of 

 the salmon. M. Edwards does not appear to have ever seen the 

 male. — From the Transactions of the Berwickshire Naturalists' Club,

Fossil Infusoria in Amber. 



In a paper recently read before the Berlin Academy, Prof. Ehren- 

 berg drew attention to the occurrence of fossil Infusoria in amber, a 

 fact of considerable interest connected with the phsenomena of the 

 tertiary formation of the earth's surface. The following nine species 

 had already been detected by him in amber : — 



Amphora gracilis. Navicula amphioxys. 



Cocconeis borealis. Bacillum (tenuis). 



Cocconema Cistula } Pinnularia capitata. 



Fragilaria rhabdosoma ? Gastrum. 

 Navicula affinis. 



Navicula amphioxys is most numerous, and with Cocconeis and 

 Amphora together with Pinnularia Gastrum form the mass. — W. F.
