CRUSTACEA (i^SPIA. 287 



Occurrence. — Of this species only 3, partly defective specimens were 

 collected by Mr^Warpachowsky at Stat. 53, occurring north of the island 

 of Kulaly. 



In the collection of Dr. (irimm there is a single specimen, which was 

 taken in the middle part of the Caspian Sea, near the western coast, from 

 a depth of 10 fathoms. 



Gen. G. Pandorites, G. 0. Sars. 

 Syu.: Pandora, Grimm. 



Generic Characfers. — Body but little compressed, and quite smooth 

 above. Coxal plates of moderate size; 1st pair tlie smallest; 4tli pair but 

 slightly emarginated posteriorly. Epimeral plates of metasome well develope d 

 Urosome short and stout. Eyes placed close to the lateral lobes of the cephalon. 

 Antennae rather slender, but not nmch elongated, equal-sized, the superior 

 ones with an accessory appendage. Oral parts normal. Gnathopoda very un- 

 equal, and of the same structure in the 2 sexes; the anterior ones of normal ap- 

 pearance, tlie posterior ones, however, peculiarly developed and rather power- 

 ful, resembling those in the genus Ganimar acanthus, the propodos being 

 greatly expanded distally, with tlie palm arcuate and having below a parti- 

 cularly long and slender spine. Pereiopoda not much elongated, and of normal 

 structure, basal joint of last pair lamellarly expanded. Last pair of uropoda 

 small. Telson likewise small and cleft to the base. 



Eemarks. — This genus has been established by Dr. Grimm to include 

 a rather peculiar Gammarid from the Caspian Sea to be described below. 

 But as the name lie proposes. Pandora, has been used long ago, and as 

 also the derivations Pandorina and Pandorella have been appropriated in 

 Zoology, I propose to change the name to Pandorites. Besides the typical 

 species, P. podoceroides. Dr. Grimm refers another form to the same genus 

 under the name of P. cocca. But this form differs essentially both in the 

 structure of the antennaB and gnathopoda, and cannot therefore in my opinion 

 be regarded as congeneric. The specimens of the latter form contained in the 

 collection of Dr. Grimm and taken from the very considerable depth of 108 

 fathoms, would all seem to be still immature.

 (PI. XIX). 



Specific Characters. — Body rather slender, with evenly rounded back, 

 and exhibiting in its outer appearance some resemblance to that in the
