The specimen on wliich Dr. Winkler founds his new species is 

 from the Lithographic stone of Eichstadt. It is in a good state of 

 preservation, its length being thirteen inches ; the head is somewhat 

 mutilated, but the orbital, opercular, and maxillary bones, are easily 

 recognized, but, unfortunately, there is no trace of the teeth. A 

 slender line which extends from the neck to nearly the end of the 

 tail, marks the position of the spinal marrow (moelle epiniere), or 

 dorsal chord, forming a ribbon divided into small squares, and which 

 is protected above and below by bifurcated bones, which terminate 

 in single points, — the neural and hagmal arches. The fins are entire 

 and in their natural positions. A large portion of the integumentary 

 envelope is preserved, which our author thinks is naked or devoid 

 of scales, but covered with numerous small spots or groups of very 

 fine strife, and these groups have between them spaces which are 

 not striated. On examining these striae with a magnifying glass, 

 he finds that they are composed of long tubercles, a little undulated, 

 and sometimes bifurcated, and they are covered by a fine coat of 

 enamel. Upon comparing his specimen with the figures and de- 

 scriptions of the other most perfect example known, the Ccelacanthus 

 striolaris, Miinster, our author finds that both specimens are alike in 

 size and general form, and in the relative size of the head to the 

 body ; in the number and position of the fins, and in having a prin- 

 cipal, and an accessory caudal fin placed at the end of the dorsal 

 chord ; and also in the dorsal and anal fins being each supported by 

 a broad flat bone, and not upon interapophysary osselets. He says 

 they differ in the following particulars : — 



1. C. striolaris, according to M. Willemoes-Subm, has 19 rays in the second 

 dorsal fin, his has but 13 or 14. 



2. The anal and second dorsal fins have each 19 rays in G. pencillatus ; in his 

 specimen there are but 10 or 11 rays. 



3. A difference' of a few rays is also observed in the first dorsal. 



4. The difference in the number of the rays of the pectoral fin is also great 

 between the two species, — 13 or 14 in C. pencillatus, 20 in his. 



5. The ventral fin in. G. striolaris is small; in his specimen it is the largest of all 

 the fins. 



6. C. Kohleri shows plainly fulcra to the first dorsal and the caudal, but none of the 

 fins of his specimen have these small spines on the edges of the rays. 



7. The specimens in the Munich Museum have scales, and also fulcra, which are 

 but modified scales, and the absence of fulcra in his specimen coincides with his view 

 that the skin was naked or covered with small dermal tubercles. 



These differences, he thinks, are quite sufficient to prove that his 

 Caelacantli is a new species, and which Dr. Winkler names GoelacantJms 

 Sarlemensis, for the very novel reason that it was first studied 

 and described in the town of Haarlem.
