The first chapter is " liber die Drlisen in den Boineu der Phronimiden," the second discusses 

 "die Gehause der Phronimiden" (Gerstaecker). 



This paper, according to Haller, explains in great detail the gland in the grasping-hand of 

 Phronima sedentaria, pointing out its position, form, number of outlets, microscopic 

 constitution, and suggesting that it is either a poison-gland, or more probably emits a 

 secretion necessary for dissolving the interior of the creature used by the Phronima as a 

 nest or nursery.

This paper raises certain objections to the views of Exner and Grenacher on " mosaic vision," 

 which are met by Grenacher in an appendix (pp. 168-170) to his great work on the 

 subject, Untersuch. iiber das Sehorgan, 1879.

Caprella fretensis, n. sp., is described and figured, from two specimens found at Salcombe in 

 South Devon, at which place the estuary yields Proto ventricosa, 0. F. M., and many other 

 Amphipods. Meyer accepts Caprella fretensis as a distinct species, but considers it 

 extremely close to Caprella septentrionalis, Kr0yer. It is abundant at Ilfracombe, and 

 very variable, some specimens coming far nearer than others to the pubUshed accounts of 

 Kr0yer's species just mentioned. 



The correlation between the spines on the pabns of the hind legs, die Einschlagdorne, in the 

 Caprellida;, and the generic divisions of that family, is noticed. Mayer, die CaprelHden, 

 p. 13, remarks that it would be difficult to carry through the employment of this character 

 for generic division, since Caprella acanthi/era, for example, would then have to be 

 transferred to another genus. This indeed is on other grounds suggested by Boeck, who 

 thinks that Caprella acanthifera may belong to his genus ^giiiella. Of Stimpsonia
