to two females. The length of the females about 60, of the malea 

 about 45 millims. 



II. Ascarides from Toothed Whales. 



Of these Schneider only describes Asairis lobulata, found in 

 PJatanista gnngetica. It belongs to the same group as A. osculata. 

 Rudolphi described A. simplex from Phoccena comtminis ; and Du- 

 jardin refers to the same species a worm from a dolphin taken near 

 the Maldive Islands. The twenty bottles in the University Museum 

 contain three species : — 



1. Ascaris lofmlata, Schn., from the buccal cavity of a Gangetic 

 dolphin in the Hooghly. 



2. Ascaris simj^hx, Rud. To this species the author refers all 

 the Ascarides obtained from toothed whales and dolphins on the 

 coasts of Denmark, the Fteroes, and Greenland, namely : — from 

 Lagenorhynclms albirostris (2), Denmark; Beluga leucas (7), Green- 

 land; Hiiperoodon rostratus (1), Fferoes; and Monodon monoceros (3), 

 Greenland. 177 individuals occurred in one whitefish, in the pro- 

 portion of one male to two females. The latter reached 200, the 

 males 130 millims. in length. 



This worm belongs to Schneider's first group. The lips are very 

 similar, and have in front a pair of lobes separated from the rest of 

 the lip by a sinuosity ; on the inner side of the lobes there is an 

 armature of teeth. Of the caudal papillae of the male the four 

 nearest the apex are conical and arranged in pairs, the outer one of 

 each pair being the longest. Close behind the anus are two short 

 papillae on each side, or sometimes only one large one ; and on 

 each side of the anus there is a group of six short papillae. 



Ascaris angidivcdvis, Crepl., the only species described from a 

 whalebone-whale, was obtained at Bergen by Koren from Balce- 

 noptera rostrata. The author finds that it is identical with A. sim- 

 plex. 



3. Ascaris conocephalus, sp. n. This species was described by 

 Diesing under the name of Conocephalus Ujpicus; but the hood in front 

 of the mouth described and figured by him does not belong to the 

 worm, but is composed of coagulated mucus or of portions of the 

 intestinal epithelium of the dolphin in which it was found. It has 

 been obtained in great numbers, usually from the stomach of dol- 

 phins, from various parts of the Atlantic between Africa and Ame- 

 rica. Of 370 individuals in our collection about half were males. 

 Females 90, males 70 millims. long. 



This species is nearly allied to A. simplex. The labial lobes, 

 which are armed with teeth, are narrower and separated by a 

 deeper notch from the rest of the lip. Of the papillae in the male 

 three, or sometimes only two, of the hindmost are conical ; close 

 behind the anus there is on each side a group of seven short papillae. 

 The other papillae are arranged in three well-marked rows, but 

 they become smaller and less regular towards the anus. — Oversigt
