First record of Pilumnopeus convexus (Maccagno, 1936) (Crustacea, Decapoda, Pilumnidae) from the Indian coast

Pilumnopeus convexus (Maccagno, 1936) (Pilumnidae) is recorded for the first time across the Indian coast. The species has so far been reported from coastal waters of the Red Sea, Pakistan and Persian Gulf. P. convexus can be easily distinguished from closely related species in having transversely hexagonal carapace, acute anterolateral teeth and tip of the male left gonopod curved to form a hook like structure. Possible explanations to the new record are discussed

Extraosseous Ewing′s tumor of larynx: A rare presentation

Primitive neuroectodermal tumors (PNETs) are a group of highly malignant tumors composed of small round cells of neuroectodermal origin that affect soft tissue and bone. PNET of the larynx is extremely rare. We report a case of a 41-year-old male who presented with the complaints of progressively increasing stridor of 3 months duration, which was diagnosed as a case of neuroectodermal tumor in the subglottis. Patient was subjected to microlaryngeal surgery and the tumor was excised. Postoperatively, patient was given three cycles of chemotherapy comprising of ifosfamide, etoposide, and mesna, along with granulocyte colony stimulating factor, with 21 days interval. After chemotherapy repeat computed tomography scan showed no evidence of the tumor and no lymphadenopathy. Patient is symptom free for 18 months following completion of treatment. He is under regular follow-up and is undergoing monthly serial endoscopic evaluation

On population structure and breeding biology of burrowing crab Dotilla blanfordi Alcock, 1900

Background The present study investigated the population structure and breeding biology of the burrowing brachyuran crab species Dotilla blanfordi Alcock, 1900, which is commonly found on the sandy beach of Bhavnagar, located on the Gulf of Kachchh, Gujarat coast, India. Methods Monthly sampling was conducted from February 2021 to January 2022 at the time of low tide using three line transects perpendicular to the water line, intercepted by a quadrate (0.25 m2) each at three different levels of the middle intertidal region: 20 m, 70 m, and 120 m. The quadrate area was excavated up to 30 cm and sieved for specimen collection. The collected specimens were categorised into different sexes viz., male, non-ovigerous female, or ovigerous female. For the fecundity study of D. blanfordi, the carapace width (mm) as a measure of size as well as their wet weight (g), size, number, and mass of their eggs were also recorded. Results The study revealed sexual dimorphism among the population, with females having significantly smaller sizes as compared to males. The overall population was skewed towards females, with a bimodal distribution of males and females. The occurrence of ovigerous females throughout the year suggests that the population breeds incessantly throughout the year, with the highest occurrence in August and September. A positive correlation was observed between the morphology of crabs (carapace width and wet body weight) and the size, number, and mass of eggs
