A revision of Ernst Haeckel's determinations of a collection of Medusae 1 5 1 



No. 22 in the list, Greenland, H. P. C. Molllr, is determined by Haeckel as 

 Sarsia g/acialis; this specimen really belongs to S. princeps. Haeckel's statement 

 of the colour of the species was based on sketches made by H. P. C. Moller. These 

 sketches are in our museum and they were drawn partly at Frederikshaab in 1839, 

 partly at Godthaab in 1840; they evidently represent Sarsia tuhulosa and noi princeps, 

 showing no trace of an apical canal. 



No. 11 in the list, taken north of the Faroe Islands by Steincke and identified by 

 Haeckel as Codonium princeps, is unfortunately not in the collection. It is very 

 improbable that this species should have been found in this southern locality. 



Since no type-specimen was pointed out by Haeckel, I designate No. 12, Umanak, 

 Fleischer, 1865, as Neotype. 



Sarsia tubulosa 

 1879, p. 16. 

 Specimens identified by Haeckel as Sarsia tubulosa are retained from the following 

 localities: 



(15) Iceland; Steincke. 



(16) Bordeyri, northern Iceland; Steincke. 2 specimens. 



(17) Isafjord, Iceland; Mariboe, 1865. 2 specimens. 



(18) Faroe Islands; Steenstrup, 1844. 2 specimens. 



Steenstrupia galanthus 



1879, p. 31. 



[Steenstrupia nutans (M. Sars)] 



No. 118 in the list, 49' N. 7" W., off the mouth of the English Channel, Hygom, 



1857, is labelled by Haeckel Steenstrupia {rubra Forbes?). There are two specimens, 



belonging to S. nutans. 



Stomotoca pterophylla Haeckel. 

 1879, p. 52, PL IV, fig. 10. 

 (168) 20' 36' N. 76" W., north of Cuba; Andrea, 1867. 3 specimens, one of 

 which I designate as Neotype. 

 Mayer (1910, p. 113) gives a new description of this species, slightly differing from 

 that of Haeckel. Mayer presumes that certain errors in Haeckel's description are 

 due to the state of preservation of the specimens. It is true that this may account for 

 the absence of an apical projection and the finely serrate inner margin of the ring- 

 canal. The so-called " Ocellarkolben " are rudimentary tentacle bulbs, and they have 

 no ocelli; their number is as stated by Haeckel, and on the whole the description is 

 in good accordance with the structure of the specimens. 



Pandea saltatoria 



1879, p. 54. 



In the text of his monograph Haeckel only mentions the original specimen from 



Norway described by M. Sars (1835) as Oceania saltatoria {Pandea saltatoria Lesson 



1843), a species which has never been identified with certainty, though Hartlaub 



(1913, p. 336) is inclined to think that it was an Aglantha.
