largest of wliich inea.siued 1^ iiiclies long; "they i)rcseiited the peculiarly flexed state 

 of tlie chylous iiitestiue or stomach, as described by Dujardiu." Cobbold determined 

 the worms as "characteristic specimens" of .1. Himplex Eudolphi, and states that 

 ".4. ddphini of Uud<)li)hi" must clearly be regarded as identical with this species. 



K'egarding Cobbold's statements, it may be remarked that they were made two 

 years before Krabbe determined what a " characteristic specimen" of .1. simplex was, 

 and aKso, as his later articles show, he did not clearly understand the history of .1. 

 (Iclphiui. His determinations, therefore, are worthless. Cobbold (1870", p. 42) refers 



again to the specimens collected by Anderson, and states 

 they correspond to A. ,simplt'.r of Dujardiu. 



Ivrabbe (1S78, p, 47-4!», r.'suine, p. V2) referred to A. sim- 

 pler all the ascarides found in the toothed whales from the 

 coast of Denmark, Faroe, and (Ireenland, namely, in two 

 specimens of Lnijcnorhiinchm albirostris from Denmark, in 

 seven specimens of Beiuf/d Iritcas {^Deiphinaptcrus leiicas) 

 from (xreenland, in one specimen of Ili/peroodon rostratus 

 from Faroe, and in three specimens of Monodon monoceros 

 from Greenland. He also had some young specimens of AfiafHa from Phomcnn com- 

 mnuis ( = 7*. pliocaciid), but he could not deli nitely stale that they belonged to .1 . simplex. 

 In one Behiya leucas 177 specimens were taken, about one-third of which were males; 

 the males measured 130""", the females L'OO"'"'. This form (.4. simph-x) belonged to 

 S('hneider's (iron)) A (intermediate lips absent, labial dentigerous ridge present). 

 The ]ii)s were of nearly equal size; each bore anteriorly two lobes (fig. 23), which 

 were constricted from the base and armed on their inner surface with a row of small 

 teeth; on the end of the tail of the male (tig. 24) there were four pairs of conical 

 papilliie, of which the outermost 

 was longest; between these and 

 the cloaca were found two short 

 papillae, occasionally apparently 

 united in a double papillae; on 

 each side autero-lateral of the clo- 

 aca were six short i)apillae, then 

 followed on each side one row of 

 long papillae or two rows which 

 were closely approximate. Krabbe 

 obtained from Koren specimens of 

 the worm which Crei)lin had de- 

 scribed from Jiahieiioptcra rostrata 

 as Ascuris unffuliralris, but was 

 unable to notice any specific dif 

 fercHces between these and the form he (Ivrabbe) had determined as ^1. simi)lex. 

 The following year Cobbold (1879, p. 42G) reverts to the species A. simplex, but 

 has decidedly confused the history of the worms he discusses. He states that A. 

 simplex was originally found in the dolphin of the Gauges, and later by Albers in the 

 <:ommon porpoise; he admits .4. Dussumierii as distinct from A. simplex, but claims 

 that "Lebeck's A. delphini''' is identical with the latter species; yet the worms from 

 the dolphin of the Gauges which he (Cobbold) examined and determined according to
