type, and restricted the name to Gray's later described Patiria ocelli- 

 fera and crassa. SI a den in 1889 added a third species. These three 

 species are without a tenable generic name, and the group may therefore 

 be called Parasterina, the type being Patiria crassa Gray. 



11) Palmipes Agassiz 1835, is antedated by Anseropoda Nardo, 

 1834, type Aster las placenta Pennant. Palmipes is not tenable. 



12) Pararchaster Sladen 1885, though invalidated by the previously 

 described Benthopecten Verrill (American Jour. Sc. XXVIII, 1884, 218) 

 is still employed by Ludwig and others. 



13) Pentaceros Schulze 1760. As noted under A. s tropecten, Schulze 

 is not a binomialist ; added to this his Pentaceros, even if a genus (which 

 it is not) has no specific names, Sherborn to the contrary, notwith- 

 standing (Index Animalium). Under Pentaceros Sherborn cites »gibbus« 

 and »planus «. Schulze, however, says: Die Arten sind entweder 

 platt, planae, oder aber »höckericht und bauchicht« gibbae« — plural 

 descriptive terms of the most general character. Under modern rules 

 absence the of a species upon which to hang the generic term would 

 be enough to throw out Pentaceros. Schröter in 1782 (Musei Gott- 

 waldiani Testaceorum Stellarum marinum, etc., Nürnberg, p. 58) used 

 Pentaceros, but he is not a consistent binomialist, and his »generic« 

 names are not tenable. Pentaceros for starfishes was first given binomial 

 standing by Gray in 1840, but this is unfortunately invalidated by 

 Pentaceros Cuvier and Valenciennes, 1828, for fishes, leaving Oreaster 

 Müller and Troschel, 1842, in possession of the field; type 0. reticu- 

 latus (Linn.) M. and T. The family becomes the Oreasteridae. 



14) Pentagonaster Schulze. This will meet the fate of Pentaceros, 

 and is superceded by Goniaster Agassiz (type, Asterias tessellata Laink). 

 The name Pentagonaster was given validity by Gray in 1840 for a small 

 group of which P. pulchellus is type. Steplianaster Ayres, adopted by 

 P erri er, is long antedated by Pentagonaster Gray, while Phaneraster 

 Perder is similarly invalidated by Goniaster. The Goniaster of Sladen 

 is quite another animal and has been renamed Psen dor caster by Verrill.

Als ich meine im Jahre 1905 gesammelten Cestoden durchgesehen, 

 habe ich ein Exemplar gefunden, welches mir von Prof. Dr Samfirescu 

 zugesandt worden war. Auf der Etikette war nichts andres ange- 

 geben, als daß der Cestode von einem Bahnbeamten herrührt. Dieser
