41. Ancliura fusiformis Meek. 



This species was found associated with No. 39, at Coalville; and also 

 in the Cretaceous sandstones at Old Bear Eiver City, some thirty -live 

 miles to the northeastward, where it is associated with Inoceramusprob- 

 lematicus &c. 



42. Turritella coalvillensis Meek. 



This, together with Nos. 33, 34, 36, 43, 44, 45, 48, and other species, 

 was found in a calcareous sandstone layer in the first ridge of Mr. 

 Meek's section at Coalville. It has also been found in Southern Utah. 



43. Turritella spironema Meek. 

 See remarks under No. 42. 



44. Turritella [AcUs f) micronema Meek. 

 See remarks under No. 42. 



45. Turhonilla {Ghemnitzia f) eoalmllensis Meek. 



This form is much like those in the Laramie beds of Bear Eiver Valley 

 which Mr. Meek and myself have referred to Goniohasis. None of the 

 Coalville specimens are entirely perfect, but, so far as I can see, their 

 marine associates only, suggest the impropriety of classifying them 

 generically with the Laramie fossils just mentioned. 



46. Eulimella f inconspicua Meek. 



This, together with No. 35 and other species, was found by Mr. Meek 

 in stratum No. 16 of his section at Coalville, associated with brackish 

 and fresh water forms. See remarks under No. 29. 



47. Eulimella f chrysalis Meek. 



See remarks under Nos. 29 and 45. 



48. Eulimella f funicula Meek. 



This species, unlike the two next preceding ones, which have been 

 referred to the same genus, has marine associates only, having been 

 found at Coalville only in a layer of calcareous sandstone in the first 

 ridge of Mr. Meeli's section. I described and figuretl a form from the 

 North Fork of Virgin Eiver, Utah, in vol. iv Expl. & Sur. West of the 

 100th Merid., and referred it to this species, with which it is probably 

 identical. It was there associated with a form which I referred to 

 Admetopsis gregaria Meek, and the two species are also found associated 

 together at Coalville. 



49. Valvata nana Meek. 



This little shell was discovered by Mr. Meek in stratum No. 16 of his 

 Coalville section. See remarks under No. 29. 



50. Fusus {Weptunea f) gabhi Meek. 



This and the follomng species were found in the sandstones of the 

 second ridge of Mr. Meek's section, and, so far as I am aware, they have 

 never been recognized at any other locality. 



51. Fusus (Neptunea) utahensis Meek. 

 See remarks under No. 49. 



52. Admetopsis rJiomhoides Meek. 



This form and No. 53 are associated together at CoalviUe, and I be- 

 lieve them to be specifically identical. 



53. Admetopsis gregaria Meek. 



See remarks under Nos. 48 and 52.
