mension, while the long jalates, which are exceedingly variable in form 

 measure about 0,2 to 0,8 mm. Some of the rods are fairly regular with 

 a few perforations in the middle and many smaller ones at the extre- 

 mities (11). In the oral disk, and in the membrane between the oral 

 scales and base of tentacles are many very irregular perforated rod-like 

 plates, and branched rods, the latter usually without perforations. No 

 tAvo of these rods and plates are alike, so that a description is futile 

 (figs. 9, 13). 



Some of the viscera has been ejected through the mouth, even dis- 

 placing the calcereous ring. A descri^^tion of the internal anatomy 

 therefore cannot be given. 



Remarks. — This species is characterized by the possession of 

 3 complete longitudinal series of pedicels on the sole, by the heavy dor- 

 sal scales, and absence of regular anal and oral valves , as well as by 

 the forms of the deposits herewith figured. In Thé el's key to the genus, 

 californicus would be ranked along with phaniapus^ complanatus, and 

 pandanensis^ from which it differs not only in the form of the body, but 

 in details of deposits. Psolus digitaius Ludwig has peculiar digitate 

 tentacles, while Psohts fimhriatus Sluiter is a near relative of it and 

 hence is not directly comparable, although both species have 3 series of 

 pedicels on the sole. Psolvs parmatus Sluiter differs in general form, 

 and in having less numerous pedicels, as well as in other details of 

 structure, including the deposits which depart widely from those of ccdi- 

 foi'nicus, Psoitis pauper Ludwig and Psolus japonicus Ostergren are 

 comparable with fabricii. and Psolus propiiuptus Sluiter with squamatus. 

 Consequently the are very different from the present form. 



4. Zwei neue beschuppte Copeognathen aus dem Bernstein. 



Von Dr. Günther Enderlein, Berlin. 

 Mit 6 Figuren.; 



eingeg. 4. November 1905. 



Der gütigen Erlaubnis des Herrn Geheimrat Prof. Dr. Branco 

 und der freundlichen Unterstützung des Herrn Dr. Stremme verdanke 

 ich die Möglichkeit, 13 der Stücke \onÄi?i2Jhiento>}iwnparadoxu))iPict. 

 Hag. 1856 untersuchen zu können, die Hagen bei seiner ausführlicheren 

 Beschreibung (1882) vorlagen. Bei Untersuchung dieser Exemplare, die 

 aus der Künowschen Sammlung stammen und jetzt im Besitze des 

 paläontologischen Instituts des Kgl. Museums für Naturkunde in Berlin 

 sind, ergab sich, daß zwei der Stücke (Nr. 91 und 94 der Künow- 

 schen Sammlung) durch die Form der Flügelschuppen von allen übrigen 

 Stücken abweichen. Durch eine vergleichende monographische Durch-
