 coming free of the tail 7^'". Of the spur 7i"'. Expanseofwings8"3"'. 



Hub. same as the former. 



4. Rhinopoma CarGlinense, GeofFr. As, from want of a good 

 description, I am not certain with regard to the determination, I will 

 communicate the description of the animal in my possession. 



Fur brownish gray. Above darker than beneath. Base of the hairs 

 whitish. Ears wide, naked, only haired outwardly at the cohesion, 

 and inwardly in front where the concavity commences. 6 — 7 warts 

 on the front margin of the ear. Furnished with longer bristle-hairs 

 on the nasal bridge, at the toes of the hind feet, and at the anus and 

 sexual orifice. Lip large, projecting far beyond the inferior lip. 

 Wings blackish brown. The membrane between the anterior and 

 posterior legs is, in the vicinity of the body, beset with small tufts of 

 hairs. The margin of the interfemoral membrane has, in the neigh- 

 bourhood of the tail, two tooth-like projections, of which the exte- 

 rior one originates from the end of the spur. Tragus 4-angular, 

 at its inner margin somewhat sloped. Length of the entire animal 

 4", of the body from the tip of the nose to the commencement of 

 the tail 1" 11"', of the tail 2" 1"'. Usually the tail is inclosed 8'",

 No. IV. Remarks on the Structure and Habits of Lepidosiren 

 annectens. 



As stated at the commencement of these * Horae/ and im- 

 plied by our motto*, we consider them intended to convey 

 whatever information, whether partial or complete, may come 

 in our way, and tend to illustrate zoology. The appearance 

 of Professor Owen^s important and carefully wrought paper 

 upon Lepidosiren annectens, printed in the last volume of the 

 Transactions of the Linnaean Societyf^ had been some time 

 looked for, and the interest which its perusal excited was still 

 further heightened by the loan of the other specimens of the 

 remarkable animal which Mr. Weir discovered on the Gambia, 

 and which have been kindly trusted for some time in our pos- 

 session by the sister of that gentleman, now residing in Edin- 

 burgh. Upon examination of these specimens, some of the 

 external parts appeared to vary from the figure and descrip- 

 tion given by Mr. Owen ; and as every observation relating to 

 the structure of an animal so curious must draw out some in- 

 ference associating with those around it, we shall describe 

 them minutely. But for the sake of those who may not have 

 access to the valuable Transactions alluded to, which, through 

 the various changes incident to scientific societies, especially
